LG 48CX

Picking up a 55cx in a few days...I am pumped! Should push my 9900ks/rtx 2070 to the limit. Will report on my experience.

Can anyone recommend some dark, atmospheric single player games that look fantastic on the screen? It is halloween after all :).

I am planning on checking out all the amazing planet coaster custom parks on the steam workshop and also replaying some of the silent hill series...maybe some doom 3/tc's and REmakes.
 
LOL wut?? I mean the LG can run up to 175Hz or nearly a 50% increase in refresh rate over the CX so sure I can believe it delivers better sample and hold motion clarity in that case. My Omen X27 which is a 240Hz fast TN also beats my CX at 120Hz sample and hold. But 3x more clear? Yeah sounds like BS to me even my Omen isn't 3x more clear. Not a surprising claim from someone who has an obvious hard on for the Nano IPS panels I guess 🤣
My hard on certain things is definitely impressive, but displays is not one of them. Maybe it's not EXACTLY 3x times smoother, ffs I didn't measure. But the difference is huge none the less in favor of the Nano IPS. Just no contest, really. Sample and hold does its thing even to the fastest OELD pixels or whatever. The Predator was set to 144hz btw, I forgot to mention. No really, OLED with no VRR at 120hz simply sucks in comparison.
Add 1100+ dimming zones to the 38" LG panel, call it gsync ultimate and it will wipe the floor with the OLED TV all day and night in every contest possible. That's how it is.

Anything without VRR sucks whether it's OLED and IPS. And since you wanna play the make believe products game we can say the same thing about a CX. Give it a 240Hz/360Hz refresh rate along with Panasonic's heatsink implementation that allows OLED's to hit 1000 nits peak brightness and now what? OLED will stomp that IPS in every contest possible. Faster response times that make every bit of use out of 240Hz/360Hz, per pixel dimming with 1000 nits peak brightness WITHOUT SHITTY BLOOMING, the only last bastion left for IPS is that silly overexaggerated viewing angles argument.

No it won't because it will still have tempo burn in and if you unplug it from the wall socket the tempo may become the permo. The ahva-like viewing angles also are not going anywhere with 360hz. And concerning the blooming... shocking, but OLED has it too. Turn off the lights and set the black background, move the cursor around and you will see 3-5cm white blooming around it. Just like FALD, lol. Honestly I tested it yesterday after reading online that OLEDs have blooming too. It is not as severe as FALD blooming of course! I don't think you will notice it outside the all black background, but still.
In any case I do not want to pee on the OLED parade too much and I agree that it is the best display option for gaming for 2020 at least, considering the price, mind-blowing HDR performance and blacks without obvious blooming and overall image quality. My point is that without VRR - OLED sucks just like any LCD monitor in terms of image smoothness and clarity in motion in comparison to the modern 38" IPS with hardware g-sync module. On that we agree, it seems.

Edit: And the worst thing is the fucking size which is not going anywhere either.

Size is a completely subjective matter, the CX being no smaller than 48" isn't an advantage or disadvantage that's all personal preference. And HDR is a good point because as good as the GL950 is, it has no meaningful HDR at all which means moving forward it is going to get quickly outdated as more and more game developers get the hang of implementing HDR into their games.

Dude what are you talking about? OLEDs do not have any bloom. The way your eyes work when looking at a very bright object on a pitch dark background is not bloom. And it's nothing like a FALD. You have to be really confused or have some kind of eye problem to think that.
 
Yeah was about to say... Also the temporary burn-in (more accurately image retention) isn't a thing on every OLED panel. My CX doesn't have it (at least with my settings it doesn't, not running at full brightness all day). Rtings measured some (but it's probably hard to even see in real life) on their 48 but not 55. Apparently it varies from unit to unit.

Exactly, this is the way the eyes see things specifics. I can't describe how exactly that works but it surely looks like fald halos )) Aaand I don't think it's only the eyes, I think it is also the inner reflections from the glass, that covers the OLED panel.

Except OLED does not have blooming, not in the way FALD backlights have. This demonstrates what FALD does and what you just won't see on an OLED thanks to per pixel local dimming:



What you are talking about is what happens if you turn on a flashlight in the dark. It appears very bright compared to turning it on in a room with some ambient lighting. It has more to do with how our eyes perceive it than anything that the OLED is doing.

I will give you the size, it's not all that practical but out of all the compromises currently available, it's at least something you can reasonably do something about - just put it a further away! Or use it like an ultrawide with a black background. I measured that if you use it at 3840x1600 (or the equivalent of that in terms of window sizes so you can run at full 4K) you have effectively a 43" ultrawide.

There is never a perfect display tech on the market but I really hope OLEDs start becoming available at smaller sizes. I would instantly go buy one if LG released a 120+ Hz OLED version of the 40" 5120x2160 panel they are planning.
 
Any area blooming you see on an OLED is because of how your eye takes in light. There is no actual blooming on an OLED panel.

This. I see "blooming" on my c9 but it is nothing like on a LCD. My eyes just suck. I don't find it distracting on a OLED but it doesn't annoy the shit out of me when I see the halo effect on LCDs. I never like FALD cause of it.
 
I think I found a mode that actually works, and I also suspect explains why some people can uncheck the "enable settings for the selected display".
If windows VRR is enabled, that probably kicks in when g-sync is turned off. and windows VRR actually seems to work perfectly. when you disable "enable settings for the selected display" I think you are turning g-sync off and letting windows VRR take over. That's probably why it has worked for some people, and others have just said nope, doesn't work whatsoever.
So to verify, I can turn off g-sync completely in nvcp (entirely uncheck "enable g-sync. g-sync compatible), and turn on VRR in windows, and it all works. I have left it that way for about an hour now, no tearing or stutter when capped to 118, 115, 110, 100 fps.

Full settings:
windows 10 pro 2004 - under display-> graphics settings: hardware accelerated gpu scheduling on, variable refresh rate on
OLED55CX6LA (european model, .26 firmware) - game mode, all processing off, instant game response on, amd freesync off
Clean install 456.71, global vsync-on, low latency mode: on, 3840x2160, 120Hz, 10bpc, rgb, full. g-sync unchecked altogether.

The green-button-spam window reports vrr on, but does not show the fluctuating refreshrate (whatever, it was broken and showed 5.5 hz anyway). Pendulum demo does not work, I assume since it specifically wants g-sync, and g-sync is technically off. It clearly works in games. I'm fully expecting it to break and stop working minutes after I type this, would just be typical of the cx behaviour :D
 
This is just not true. The 360hz panel is 2.6ms g2g average which is plenty for 240hz, though some transitions are too slow for 360hz, but you still get some benefit.. The Samsung G7 is ~2.9ms, which is plenty for 240. There ARE some slow transitions that exceed the full transition time but that's not the same thing as "refresh rate is all marketing".
I'll just note that g2g times tend to be "best case"; you don't have equal transition times between the entire color range.
 
Yes LG, please make the CXI with 240Hz. Will give me a perfect excuse to buy another one of your TV's next year. I am now a confirmed OLED addict and want more!

All the Windows setting should be doing is allowing Gsync/Freesync/HDMI-VRR(?) to work on older titles though; it shouldn't override anything as far as GPU specific settings go. You sure you're not running with just Vsync in this mode?

I am sure that I am running with v-sync on and as mentioned frame capped to 100, or 110, or 115 or 118, and all these framerates are smooth, tearing and stutter free.

Ya, Windows VRR setting is just an override for Windows Store apps; they used to break Gsync/Freesync, and even though newer games play nice, older still don't. The VRR setting is essentially an override to allow Gsync to work in those old games

Windows VRR does *not* perform VRR on its own. It's solely a UWP compatibility tweak

The smoothness people see from turning off Gsync, or unchecked the "Enable settings" button... might just be the smoothness of high refresh gaming + Vsync. Which seems even smoother because of the jank that Gsync is currently exhibiting

Same goes for 4:4:4 8bit Gsync. Pretty sure it's still broken, but it's smoother than 10bit. The only confirmed non-stutter solution at all FPS I've seen on reddit and other forums is 4:2:0 8bit

Nope, it 100% works, and nowhere in the setting itself does it state what you claim. frame limited 100 or 110 or 115 fps would've had stutter and/or tearing and it has absolutely none.

Windows might not say it, but Microsoft did

https://devblogs.microsoft.com/directx/os-variable-refresh-rate/

This new OS support is only to augment these experiences and does not replace them. You should continue to use G-SYNC / FreeSync / Adaptive-Sync normally. This toggle doesn’t override any of the settings you’ve already configured in the G-SYNC, FreeSync, or Adaptive-Sync control panels.

This new toggle enables VRR support for DX11 full-screen games that did not support VRR natively, so these games can now benefit from your VRR hardware.
 
That was over a year ago on an older build. That's not what it says or does now.
16 months and one major windows build and several smaller windows builds ago, or so :D

I made a video, with a pattern that would easily show tearing. It is also perfectly smooth, but i guess thats hard to see in a 30fps video. 115 fps limit clearly visible + gsync off and 10bit full 120 4k.

Vsync can remove tearing, and regular stutter is hard to notice with high fps on a high refresh rate monitor. Try disabling Vsync. If Gsync is still active, there will be no tearing at sub 120Hz

I'm not saying Microsoft didn't change how Windows VRR works, but come on; to imply they stealth changed it in a significant way is just a bad faith argument. In the absence of new information (and one which would fundamentally change how the feature worked), you go with what they published

Although at this point, optimistically hoping for a loophole is all we've got while we wait for LG

You need to test that with a game that can not deliver constant 100+ fps. *constant* limited fps will almost never induce stutter or tearing. Even with g-sync and/or vsync off.

Vsync can't to my knowledge do large range vrr, no. Very few would ever have bought a single g-sync monitor then.
But i tried to disable v-sync, and that changes the mode from VRR to fixed and hides the VRR option in windows (and to even turn VRR back on again, g-sync needs to be turned on first), so v-sync is either a dependency, or by some strange magic the windows VRR keeps g-sync alive after it is disabled, but without glitching.

Further things that point to it truely working:
*BFI (truemotion) is grayed out, if it was just v-sync, it should be possible to enable.
*Also consider what's more likely, than an option called VRR does VRR; or nvidia stealth-adding VRR to v-sync without mentioning it?
*green button spam says VRR

That would be really funny. But honestly I would love to see it after the awful Ampere launch.

Vsync (in general) has no limits of frame rate or refresh rate. It's not dependant or limited by VRR in any way

Vsync matches the GPU to the monitor. It will only output full frames. Thus no tearing. But if a fully rendered frame isn't ready in time for the next refresh, it will display a duplicate. Thus stutter. And input lag

Gsync matches the monitor to the GPU. As soon as a fully formed frame is ready, it displays it. Stutter is greatly reduced (only frametime stutter) as well as input lag. That's why people pay for it

You want Vsync on when you use Gsync to eliminate tearing when the frame rate exceeds the VRR range. But you can always leave it off. They're separate settings not dependant on the other. They enhance eachother but don't rely on eachother

I think the most likely option is that Windows VRR does exactly what Microsoft says it does. They gave it that name when they released it and clearly outlined its purpose. If the name is misleading, then it's a bad name. But regardless of the label they gave the toggle, it toggles what they said it does

In regard to the linus video.. I scrubbed through it and only found a brief mention of 200Hz while he was actually messing with the monitor on his desktop and his subjective few words on how smooth he felt it was. I just want to remind people that the desktop is pretty much always at the max fps, e.g. 200fps at 200Hz monitor. On a 4k screen with very high+ to ultra settings on demanding games, let alone adding things like RTX and hairworks, mods, etc. you are probably going to get much reduced frame rate averages let alone minimums. You can dial some settings in/down but some games will be lucky to get 100fps average.

For example

Horizon Zero Dawn ultimate quality 4k
RTX 3090 ~ (59fps) - 79 fps average - (..99?)
RTX 3080 ~ (50fps) - 73 fps average - (..93?)

Assassin's Creed Odyssey Ultra High DX11, TAA
RTX 3090 ~ 94 fps average (prob something like 74 <<<< 94 >>>>114
RTX 3080 ~ 87 fps average

Metro Exodus Ultra, DX12, TAA
RTX 3090 ~ 89 fps average (prob something like 69 <<< 89 >>> 109
RTX 3080 ~ 76 fps average

Dirt Rally 2.0
RTX 3090 ~ 80 fps average (prob something like 60 <<< 80 >>> 100)
RTX 3080 ~ 70 fps average

Borderlands 3 Bad Ass, DX12, TAA
RTX 3090 ~ 76 fps average (prob something like 56 <<< 76 >>> 96)
RTX 3080 ~ 65 fps average


For reference....

......25ms / 16.6ms <<< 13.3ms >>>> 11.1ms / 9.52ms

at...40fps / 60fps <<< 75fps >>> 90fps / 105fps


So on most of the heavy hitting games you aren't even hitting 120fpsHz average so nowhere near120fpsHz solid... (let alone 200fpsHz or higher on high rez monitors capable of that).
If you dial your settings in(down) to get 100fps average you'd be getting around
(70) 85fpsHz <<<< 100fpsHz >>>> 115 fpsHz (117 capped).

DLSS could help with some games but then people will be tempted to use RTX/raytracing for even more eye candy so they still aren't likely to be getting or maintaining 120fpsHz. That is in general but there are some games with much higher frame rates of course but they are the exception (Doom Eternal 3090 = 204fps , 3080 = 177fps).

I have high hopes for Cyberpunk with DLSS. I'll turn raytracing off in order to get 100fps average or so if I find I have to though.

Those numbers for AC Odyssey are too high (I have clocked a lot of hours on that game). It's about 60fps average (70 for the 3090) at 4k on ultra. Some places in the game run a bit better of course but some places will also have you dropping lower. The benchmark on that game is actually good and representative of real gameplay.

But yeah even by lowering some settings VRR is critical to have a good 4k experience - and 120hz is plenty for the time being. Still wouldn't mind a super high hz mode for older games or competitive games I play on the lowest settings. Like Diabotical (arena shooter) I'm playing at 250fps on the CX right now with my 1080 ti.
 
120Hz is definitely plenty for now. In a few more GPU + CPU cycles we will have hardware that's capable of doing over 120fps at 4k and hopefully LG will have 240Hz OLEDs by then.
 
G-SYNC Off + Windows VRR On + frame rate limit just results in Vsync stuttering. It's smooth only at a locked 120 fps. The TV reports Fixed mode instead of VRR mode, as expected. The Windows VRR setting is just a compatibility setting.

NVIDIA supports non-validated FreeSync monitors (VESA Adaptive Sync) over DisplayPort which doesn't use their database of timings. Unchecking Display Specific settings is probably taking a similar code path for HDMI VRR.

Stupid questions: I just went ahead and ordered this 48in monitor.. I currently have a GTX 1080 TI. What's the best I can get out of this with GSYNC? 1440P 120hz? Also, can I use my existing HDMI 2.0 cables until I am able to upgrade to an RTX 3090 + HDMI 2.1 cable? Thanks

The bad news: you won't be able to utilize G-Sync/VRR as it's not supported on that series.

The good news: you WILL be able to run full 4K at 120Hz...but not at 4:4:4 without a GPU that supports HDMI 2.1. I'm currently running 4K/120Hz at 4:2:0 on my 1080Ti, but I find it perfectly acceptable for anything except small red text which is extremely distorted. But it's rare for me to encounter red text, so I'm dealing with it until I can get a 3080. I could also get around it by running 4:4:4 at a lower resolution or refresh rate, but it's not a big enough problem for me to bother switching.

Unfortunately no G-Sync support on the 1080 Ti with this TV, that requires 20 series and up. Highest res you can get is 4K 120 Hz 4:2:0. Yes you can use your HDMI 2.0 cables.
