LG 48CX

I am thinking it may be the less frames I am experiencing that feels like higher input lag.

Gears 5 is running constant 120fps that could be why it feels more responsive and feels like no input lag is present.

Fallen Order and Shadows of Tomb Raider run around 60-100fps and both feel like there is some noticeable input lag.

My friend told me it is because v-sync is enabled. But i tried v-sync both enabled and disabled and could not discern much difference.

Is it correct to enable v-sync when also using g-sync?

Yes. You almost always want Vsync on with Gsync. That's how you get the best experience. Vsync on prevents screen tearing above the refresh rate, and for any random frame generated with a frametime faster than your refresh rate

Vsync and Gsync together will not add any noticeable input lag

The strange thing is without vsync enabled I got screen tearing even at 80-100 fps range. With vsync enabled everything is fine. Gsync enabled all the time. Any idea what could be causing this?

 

[kalston]

The explanation is in the link you quoted.

tl;dr when g-sync is enabled the v-sync setting controls a core functionality of g-sync without which tearing can still happen.

This thing is $1450 with $100 Hulu code, $100 Costco card and five year warranty right now through Costco. We pay for Hulu and get groceries at Costco so kind of like $1250. I had it shipped to my dad’s in NH too to duck the sales tax. Nice deal compared to the one I bought and returned earlier this year for $1600 after tax. Seems like all the problems are essentially fixed now.

Just the VRR gamma shift still lingers but you can do various things to reduce it.

As I understand it, and the way I do it, is to enable GSYNC -AND- VSYNC in the Nvidia control panel BUT keep VSYNC DISABLED in the games themselves.

Also, I set my frame limiter in the Nvidia control panel to 117fps to keep games from hitting or exceeding 120hz which can cause VSYNC only to be used which could reintroduce extra input lag.

I'm playing through Shadow of the Tomb Raider right now and I'm not feeling any notable lag and I've been paying attention for it. It's been a pretty incredible experience so far. There's no sign of "wow, the screen moves way after my mouse does." Also I'm fairly competitive in Rocket League and there's not any feel of control lag at all. For reference, my last screen was a low lag 1440p IPS gaming monitor. I know the CX is been tested as a little higher, but it's still supposed to be under 20ms.

VSync should always be enabled in the game, as the engine has different code paths and input lag optimizations for VSync.

 

[chimera991]

Your choices are:

• 4K 120 Hz 4:2:0 8-bit SDR with G-Sync (HDMI 2.0)
• 4K 120 Hz 4:4:4 10-bit HDR without G-Sync using Club3D DP to HDMI 2.1 adapter (this is what I use)
• 4K 60 Hz 4:4:4 8-bit HDR with G-Sync (HDMI 2.0)
• 4K 60 Hz 4:2:2 10-bit HDR with G-Sync (HDMI 2.0)

I would never run 4:2:0 for desktop use. https://github.com/Maassoft/ColorControl is a great tool for quickly switching between resolution/color depth settings.

Whats the best setting for desktop use where its on for at least 8 hours a day (work)?

Also, I cant figure out how to have different picture settings despite having a B8 and C9, this one just doesnt have picture settings that stick..

What about ULLM with LG CX ? Did you or someone else make some test with that ? Should we expect any issues ? Should we get better frametimes with ON/Ultra ?

 

[Porter_]

That's right. 4:2:0 looks like crap on the desktop and even in games with small text. I would buy the Club3D adapter and play at HDR 4K 120 Hz RGB 10-bit without G-SYNC. Otherwise I would play at HDR 4K 60 Hz RGB 8-bit with dithering with G-SYNC, or HDR 1440p 120 Hz RGB 8-bit with dithering with G-SYNC.

Your choices are:

• 4K 120 Hz 4:2:0 8-bit SDR with G-Sync (HDMI 2.0)

• 4K 60 Hz 4:4:4 8-bit HDR with G-Sync (HDMI 2.0)

thanks guys, much appreciated.

It should be enabled only in games that specifically work fine with it, like CS: GO. It causes stuttering in most games if globally enabled.

I tried to play this game on the CX, just couldnt do it, its too big.
And not sure how anyone expects to play competitive (i mean I dont like to lose or get my ass kicked). After switching back to my 1080p 24", it felt better and let the ass kicking commence!!!

Ahh man, so many contradicting views.

 

[shadow2761]

I'm playing through Shadow of the Tomb Raider right now and I'm not feeling any notable lag and I've been paying attention for it. It's been a pretty incredible experience so far.

I also tried SOTR last night and I can definitely notice lag but only in certain areas where the frames dip below 80fps.

In the areas where the frames are high, i.e. near the beginning pf the game there is barely noticeable lag for me.

Are you playing it max quality 4K? What GPU?

I got 1st place on the scoreboards in FFA and TDM multiple times last night on Black Ops Cold War, and that's with a 77"

You get used to it pretty quickly I think.

Firmware for Europe is up on LG support sites

Realistically, it doesn't matter if it's enabled in the Nvidia CP or in the game as long as you aren't having an issue with it. The general rule is GSYNC and VSYNC both on if you want to use GSYNC. That much at least has been nailed down for a long time.

You can in theory leave VSYNC off and GSYNC on but if the game exceeds the monitors max refresh rate, and therefore GSYNC maximum frame rate, GSYNC will turn off and tearing may result again... the thought process for allowing this being that input lag will VERY SLIGHTLY reduce with GSYNC off at the extremely high frame rates and some gamers may want this result... only having GSYNC on when the frame rate is really low, but not when extremely high in order to minimize all possible input lag.

But frankly, the lag reduction is tiny, and pretty much no one who runs GSYNC wants any kind of transition happening into and out of GSYNC mode because that breaks the whole purpose of having it on... continuously controlled smooth frame deilvery with no tearing.

This is also why most of us run with frame rate limits turned on (set a few FPS below max screen refresh rate) whenever possible and why it's so NICE having that option directly in the Nvidia drivers now. By not allowing the max refresh to hit or exceed the GSYNC upper limit we can keep (in theory) EVERY game inside the GSYNC window all the time. It's a great thing. A few games aren't working with the Nvidia frame rate limit but most are and hopefully all will going forward.

Otherwise just shut GSYNC off, turn VSYNC off, set every option on your screen you can find to minimize latency and go. You'll have the absolute minimum input lag but will have some screen tearing. You choose your poisons.

Back to the VSYNC thing for a moment. If a game has specific problems you notice with leaving it enabled in the Nvidia panel and not in the game, just try it the other way. But things should improve as we move forward with this. I'm running under the assumption that the Nvidia control panel VSYNC control is more likely to properly interface with GSYNC settings when they are both being set and controlled from the Nvidia panel rather than whatever implementation the game has even though the game's implementation of VSYNC interally may be "better" for the sake of actually using VSYNC stand alone. But once again, just do whatever works for the games you are playing.

 

[t1337duder]

I've never experienced tearing with G-Sync with V-Sync on or off. In different games I've tested, the max they will go to is with 120FPS.

4K 120 Hz 10-bit SDR. That's what I use it for most of the time for personal use while for work it runs at 4K 60 Hz because my Macbook Pro can't do any better.

 

[Makeroflostsouls]

Sweet just updated to the new .30 update and it fixed my black screen issue with starting a game. Can’t wait till evga list their 3080 water block cards. Still on my 5700xt.

 

[MrTX]

Hi guys, I just bought the LG CX48, and I have this thin vertical black line on the right side of the TV. It appears on all scenes and inputs. The weird thing is this happen after I did an update to 3.11.25. It wasn't there with the original version it came with (3.0 or something). Anyone has any idea on how to fix this? Will it go away or did I get a defective panel?

Edit: Just did a manual pixel refresher and it's gone. Phew.

I'm using a laptop with GTX 1660 Ti and HDMI 2.0 cable at 1440p 120hz 8bit RGB for now (until I can build my pc next month). My laptop can run 4k 60 hz but there is no option for this in Nvidia Control Panel. Does anyone know why? (I see PC 4k 120hz, but I can't run it because I'll get No Signal when I select it.)

It should be in the TV resolutions section. Check what Windows Display Settings offers.

Gotcha, thanks. Gonna have to settle for 4k 60hz 420 for now. Still looks awesome!

I would never run 4:2:0 for desktop use.

I would make a single exception for if you're using at least 200% DPI scaling since 4:2:0 by definition has the same chroma resolution as 1080p 4:4:4, and as someone with a father that needs the DPI scaling really cranked up (read: 150% on a 25" 1080p display; same desktop realestate as 720p) I'm not about to tell people what is and isn't "too big".

I tried to play this game on the CX, just couldnt do it, its too big.
And not sure how anyone expects to play competitive (i mean I dont like to lose or get my ass kicked). After switching back to my 1080p 24", it felt better and let the ass kicking commence!!!

Presumably you're using the 55" or 65"?

I say this because the 48" has the exact same PPI as a 1080p 24" display, so all you'd have to do is either run in windowed mode with 100% scaling or set your desktop/in-game resolution to 1080p but with GPU scaling enabled and set to "centered" (unless there's a specific "1:1 pixel" setting for 1080p resolutions on the TV?) . It'll result in window boxing, but it'll be the exact same size as that 1080p 24"

...but at that rate you might as well make a custom ultrawide resolution with a 1080p vertical resolution instead (2560x1080, 3840x1080, etc).

 

[chimera991]

Having a hell of a time using my work setup, its only outputting 4k@30hz. Hate the input lag. I think if LG really wants to advertise this as a "monitor" they should have included 1 DP input. I've already confirmed the laptop and docking station can do 4k60hz. It just has to go through DP. I was too late in canceling my club 3d DP to hdmi adapter, which I hope fixes this issue. Other wise, no 4k60hz for me on my work setup.

Really underwhelmed with the LG 48CX. Maybe its because I already have a b8 and a c9, so I've gotten used to owning an OLED.

I'm hoping the C1 or whatever the successor is to the 48CX has the goods we've all been waiting for.

Negative, I'm on a 48CX, I assumed everyone here is the same since the thread is about the 48CX... But yea, playing on a big ass monitor is a no go for me, also I'm just used to gaming on a 1080p when it comes to online FPS. I have a 280hz monitor for fps games. Everything else I'll be using the 48CX. Now to just get my hands on a 6800xt or a 3080...

 

[SmootyPoody]

Hi guys. Sorry to hijack the thread. I just bought a super ultra-wide 49" Samsung (C49RG90S) and I am having a hard time adjusting to it after being on 2x 24" for 10 years. I think I need some tools to work better with WIndows 10's.. ehh. windows.. I am so used to use the built-in maximising windows, but on such a monitor is is not really useful. Anyways...

My real question (and if anyone has any suggestings for the first problem I am happily taking them) is regarding the title of this thread. Right now there are some great deals on LG OLED CX's. Its only 55" or 65" so no 48" unfortunately. But does anyone has experience using the 55" (size wise - is it too big? I am sitting about 75-85cm away from the back table edge)?

How are people combating the viewing distance with that god aweful stand it comes with? So I am on a height adjustable table and I really appriciate the posture change and this creates a problem, because as said I am thinking of buying one of the 55"s and to combat the viewing distance I would wall mount it. But then I cant use my height adjustablility - which I am okay to sacrifice but dont want to if I don't have to. So what to to. Are there any 3. party stands that can be mounted to the table that make the display sit at the table edge far away from the viewer? or any height adjustable wallmounts?

Thank you for anyone answering any of my questions (or can point me in directions that can).

LG definitely calls it a TV, and it's definitely in the TV section of their webpage. This sounds like the dock has the deficiency not the TV.

But there's an easy way around this (and what I'm doing while working). RDP into your work laptop from whatever you normally have the TV connected to, issues all resolved.

 

[elvn]

After hearing that the VRR issue is actually fixed and finally having confirmation and details about the VRR raised black levels, I saw that the LG 48 CX was back in stock at best buy and decided to place my order.

With the bb warranty (burn in insurance for 5 yrs) and 8.75% tax here it came out to $1936. That is the most I've ever spent on a display outside of a living room TV. The only thing in that range would be my 27" apple cinema display back in the day was $1200+ (a little more adjusting for inflation) back before 2560x screen pricing came down later.

Not to get too political but my area in NYState could be headed for another covid shutdown due to high incidence so I don't know if I'll be able to do store pickup when it comes in. I'll have to see how it goes. A lot of people in my area ignore masks and gathering guidelines so the cases have spiked a lot.

I'm not really intersted in the dp adapter without VRR so I'm planning on just running it at 60fpsHz RGB with VRR on my 1080ti(s) for now. I'll probably play some souls and souls-like games since most of those are 60hz capped (other than sekiro which can be unlocked but I don't own that one yet). I'll see if I can get 60fps solid at 4k at least, and souls games and souls-like (nioh) probably look great on an OLED because they tend to be dark and horrific.

Hopefully I'll be able to get the 3090 I want in the 1st quarter of 2021 for hdmi 2.1. "2.1 in 21"...
Sucks I have to wait but it'll be closer to tax return and I usually get some back so it would work out ok in the end I guess as long as I can get one.

Congrats man. I think I’m with you, I’m going to forgo the adapter and just live with 60Hz VRR until I can snag a 3080Ti (or maybe a 6900XT).

Couldn't you just "bypass" the dock display output wise and keep the dock for other peripherals? Most modern laptops have a usb-c adapter which could be adapted to hdmi 4k 60hz with something like this:
USB-C to HDMI Adapter,iVANKY 4K@60Hz USB Type-C to HDMI Adapter

I mean, hot plugging one cable wouldn't be that terrible and usb-c are easy to connect. Similarly I always try to port video signals directly to screens avoiding passing them through a sound receiver.

 

[kalston]

I think you already knew but no VRR at all with a 1080 ti on this display, even at lower refresh rates. But you can still do 120hz 4:2:0 which looks fine in the majority of games. Depending on the game I did that or 60hz with RTSS scanline sync (lagless v-sync).

I would not have paid for a slightly overpriced Ampere card (it was from an approved shop but they still have some room to scalp) if I could do VRR with my 1080 ti even at just 60hz. But yeah I wanted to have fun in the coming months (winter AND lockdown here).

 

[kasakka]

Gotcha, thanks. Gonna have to settle for 4k 60hz 420 for now. Still looks awesome!

HDMI 2.0 should do 4K 60 Hz 4:4:4 just fine.

Your issue is the crappy shit your laptop maker put into their setup. But a DP to HDMI 2.0 adapter should fix the issue. Just for fun I tried what happens if I plug the Club3D DP to HDMI 2.1 adapter into my USB-C to DP 1.4 adapter. On my Macbook Pro it worked basically the same as just using a USB-C to HDMI 2.0 adapter with 4K 60 Hz being the max res. Which is a bummer because I really would like to get 120 Hz in that situation as well.

While a DP port on the CX would have been welcome, don't expect to ever see one. It's a TV after all. It's not worth the cost for LG to put one in when for most people the HDMI 2.1 ports will do the job, especially as HDMI 2.1 sources become more common.

I'm not even sure where they can go with these things next year. 4K 240 Hz is unlikely to happen if they keep the 40 Gbps bandwidth limit. I don't know how DSC would play with that. I suppose they can make them a bit brighter and fix the issue with VRR black levels but I fully expect the C11 to be unremarkable just as the CX is compared to the C9 series.

Yeah mainly I just don't want to pay for the dp adapter since it can't do VRR either, so whatever I'm stuck with will have to do. 60hz is fine for the moment until I get a hdmi 2.1 gpu. I'll also hook up my ps3(not 4)to try it out. Hopefully q1 2021 for an actual hdmi 2.1 feed.

 

[MrTX]

HDMI 2.0 should do 4K 60 Hz 4:4:4 just fine.

Hmmm..when I select 422 or 444 in NVCP, I get No Signal on the TV. You think it's a bad cable?

Also, I shutdown my laptop and TV last night and went to sleep. Today, I turn them back on and the TV input icon reverts from PC icon to HDMI icon. Is there anyway to make it remember the setting (because without PC mode icon, the mouse cursor has a noticeable lag)?

Make sure HDMI Ultra Deep Color is enabled and Home dashboard icon for the input is set to PC. It could still be a crappy cable.

For me it does remember the icon state. They go missing only when the HDMI cable gets unplugged so this might be some quirk of whatever you are using. My 2080 Ti or Macbook Pro don't have this issue.

I went out and got new cables today and it seems I am getting Gsync. Still have the audio lag.

My shark has not come in but when I use either of my HDMI adapters, I do not seem to be able to get the audio to send over from the PC to my receiver. I remember reading here that people got Audio to send through there was just a lot of flickering (I can attest that this is true).

Oddly this Club 3d adapter does not seem to be sending any of the audio even though windows says it is.

Any ideas?

Couldn't you just "bypass" the dock display output wise and keep the dock for other peripherals? Most modern laptops have a usb-c adapter which could be adapted to hdmi 4k 60hz with something like this:
USB-C to HDMI Adapter,iVANKY 4K@60Hz USB Type-C to HDMI Adapter

I mean, hot plugging one cable wouldn't be that terrible and usb-c are easy to connect. Similarly I always try to port video signals directly to screens avoiding passing them through a sound receiver.

I experimented with plugging the hdmi from laptop directly into the 48CX, and still 30hz at 4k. Its a work laptop so i need to get permission to use intel graphics control panel which is in the microsoft store. no longer on Intel's site.

Your issue is the crappy shit your laptop maker put into their setup. But a DP to HDMI 2.0 adapter should fix the issue. Just for fun I tried what happens if I plug the Club3D DP to HDMI 2.1 adapter into my USB-C to DP 1.4 adapter. On my Macbook Pro it worked basically the same as just using a USB-C to HDMI 2.0 adapter with 4K 60 Hz being the max res. Which is a bummer because I really would like to get 120 Hz in that situation as well.

While a DP port on the CX would have been welcome, don't expect to ever see one. It's a TV after all. It's not worth the cost for LG to put one in when for most people the HDMI 2.1 ports will do the job, especially as HDMI 2.1 sources become more common.

I'm not even sure where they can go with these things next year. 4K 240 Hz is unlikely to happen if they keep the 40 Gbps bandwidth limit. I don't know how DSC would play with that. I suppose they can make them a bit brighter and fix the issue with VRR black levels but I fully expect the C11 to be unremarkable just as the CX is compared to the C9 series.

DP, especially the new 2.0 ones have a bandwidth of something like 80gbs. If LG wont do it for their tvs, hopefully one the other brands steps up and offers a 4k 240hz display add oled to make it the top dog monitor/tv.

Anyone have luck getting atmos sound using a displayport to hdmi adapter to an atmos receiver / Soundbar?

My shark has not come in yet to fix my audio lag. Was hoping this club 3d adapter would do the trick but it seems to just cause a lot of screen flickering with 0 sound. Have tried multiple cables but it does not seem to work.

A passive DisplayPort to HDMI 1.4 cable can handle that.
