what did you do exactly to make it work?

In Windows 10:

- Open "Bluetooth & other devices"
- "Add Bluetooth or other device"
- "Everything else"
- Pick your TV from the list it populates, repeat for all the copies of the TV (it is a few different devices with the same name"
- In Device Manager, verify you see your TV listed under "Digital Media Devices"
 
After crunching some numbers, I decided the 3090 is worth it. I want a significant upgrade over my 2080 Ti and a 3080 may not be enough. The 3080 is looking to be anywhere from 30-40% gain over a 2080 Ti. So if we assume 15% gain from a 3080 to 3090, that would make it about 50-60% faster than a 2080 Ti. The leap from 2080 Ti to 3080 isn't enough for me.
 
I think the big "what-if?" with 3080/90's is overclocking. It looks like clock speeds are coming down into the 1.7-1.8Ghz range. If that's just for power and heat and the silicon supports 2.1Ghz like Turing (or more), they'll be utter monsters overclocked and even a 3080 would be a huge gain over a 2080Ti. If Samsung's fab process isn't so hot and 1.8Ghz is all they can actually do, yeah it might take a 3090 to be a real solid upgrade.

3080 may be a big gain over a 2080 Ti definitely. But that would make the 3090 an even bigger one. If the 3080 is 50% over a 2080 Ti and the 3090 is an additional 15% over a 3080, total performance gain going from a 2080 Ti to 3090 is now roughly 72%.
 
Well, just bought my 48" CX. It arrives tomorrow. This thread was instrumental in my decision to purchase. Now if I can get a 3090 sometime around launch I will be ready to roll. RIP: Wallet 1970-Sept 2020.

It's ok, you won't regret it.

You can always tuck your empty wallet under your head at night and whisper "sorry" to it.
 
It seems we are talking the new Nvidia cards. Hope this is relevant.

I have a brand new 48 CX. Figuring it all out and need a better HDMI cable. But ultimately I want to run 3 of them for sim racing in triple 4k @120hz.

I currently run SLI Pascal Titans, previously on 3 40" 4k screens, and juuust got 60 fps/60hz. Do you guys think the new 3090 is an upgrade on those, even with a single card? Been 4 years I have run with this setup.

I have a 9900k too. Two of these 3090's in SLI would slay triple 4k at 120hz, right?

Definitely an upgrade. Dual 3090's should obliterate 4k120.

Thank you, brother. Glad I could skip a couple generations. Time to dig deep again! Do you have any advice on what the Pascal Titans are worth? I have so not been gaming the past 3 years. I bet they only have 100 hours gaming on them at the total upper limit.

The RTX 3090 isn't a good value? LUL WHAT? It's the fastest GPU on the planet. Do some of you really want this for free, or cheap? I really really really hate to see this logic within our HardOCP community where, it's expected that we reside within a community of "Hard" advanced users who chase performance. We do it hard or we go home.

Every generation of GPU I have to see, hear and witness this attitude here on these forums. You people have had 2 years to tuck away $20 here and $40 there. You have old hardware, older electronics, buying habits you could have sold and or changed to make this a reality.

Value is a very personal perception that is going to differ from one person to the next. Please, speak for yourself.

I challenge all of you to start selling the crap you have laying around to make this 3090 happen. 2 weeks is a long time to clear out $1,000 worth of stuff. Wife has an old juicer she isn't using or going to use, that's $50 right there, old bar stools in the garage, that's $30 or $40, random memory? That's $10 or $20 right there. Old 1tb or 2tb hard drives, people pay $30 or $40 for these all day long. Old CPU, Video Card, Motherboards? $100 ... $200? etc etc etc. A PS4 or Xbox that you really don't use? That's another thing, get rid of your old PS4 and Xbox shit now. This is def the time to do that. It's estimated that the average house hold has $2,000 to $3.000 in unwanted items laying around that have current market value. Yes, I've read that before and it's probably true.

Getting back to this "value" comment. They are giving us a TITAN class GPU with 24GB's of DDR6, not @ $2400 dollars but at the incredible value of $1500. That's $900 off. And this is still not a good value to some of you? ... Jesus.

Anyways, good luck.

And seriously, use these next 2 weeks to sell off your unwanted crap. Tech hording is lame and a year from now, all that random shit you have laying around will be almost worthless.

See you guys at Microcenter at 4AM the morning of the 24th. And, have your damn money together. I've dreamed ... dreamed of owning a Titan class GPU. Who is going to join me?

The problem is you can really only evaluate the card’s value, retrospectively, at the END of its life, based on how many games it handled and how well it handled them on your display.

$1,500 isn’t a lot for THIS card, but it is a lot for ANY card especially at the start of a new console gen when there is so little we know about the real demands 4K gaming will put on a system going forward. It could end up having much more vram than needed and not enough RTX performance, for example. Or maybe it isn’t quite enough for 4K 120fps but almost gets there. There is more to this hobby than throwing money at it.

I’ve been playing with cards since 1998. Don’t buy into hype. Even the professional reviews can be shallow. This is still only the second iteration of RTX tech. Infancy.
 
There’s a Q&A thread going on Reddit with some actually Nvidia employees. Sounds like the new cards are full 48gbps, and more importantly, will have 10bit 4:4:4 4K 120hz available over HDMI 2.1!

He didn't specifically say 10Bit over HDMI with 444 but I'll just assume they read the question properly before giving an answer. Finally we can put this to rest.
 
And lets not forget next year. Super or Ti or both variations of the 3xxx series will be released. It will also be interesting to see what the tv manufacturers roll out.
 
I want some unambiguous confirmation that Nvidia is going to support HDMI 2.1 VRR given their conflict of interest with G-Sync.

You can support HDMI 2.1 without VRR.

Nvidia just CONFIRMED this is fixed!

The GeForce RTX 30 series will support the following over HDMI: RGB/YUV444: 8, 10, 12bpc YUV422/420: 8, 10, 12bpc Same formats are supported on HDMI 2.1 Fixed Rate Link.

So what does this mean on the 48" LG CX in comparison to new OLEDs from Sony and Vizio that support the full HDMI 2.1 48Gbps? Neither of them will produce a 48" OLED display, correct? Are there any other non-OLED displays incoming that are <48" that will support the full HDMI 2.1 48Gbps bandwidth?

I am by no means an expert but basically Nvidia has just confirmed the new RTX 30 series & drivers will fully support / match the max color depth capabilities of all HDMI 2.1 enabled TVs on the market today including the LG OLED CX. Since I believe all of these TV are 10bit panels even a cut down 40Gbps bandwidth will still support the max native capabilities of the display.

You can enable 12-bit color on those displays, same on LG C9. End result will have maybe - with emphasis on maybe - some improvement to banding due to getting higher bit depth content in to the TV's processor. 10-bit color is more than enough and the actual panels are also just 10-bit.
 
Ok so I had planned on SLI 3090's for my triple CX48 setup. But I just learned the 3090 is over 5 inches WIDE. Like, how in the HELL are you supposed to fit those in even the biggest of cases, let alone maintain a second sound card for SimVibe? Madness.

I need to find out if a single 3090 is better than two Pascal Titans. I hate that the new cards are this wide. Insane.
 
This talk of getting a 12-bit signal into the TV to be down-sampled to 10-bit for the panel as being higher quality is nonsense. People cannot even tell the difference between 8-bit FRC and 10-bit. 40 Gbps for 10-bit 4K/120 Full RGB is all you need.
 
I should have thought of this before, but it just slipped my mind. I currently have my monitor connected to my 2080ti via display port and an HDMI cable to my AV receiver for 5.1 sound. How can I accomplish this with the OLED? I can buy a good sound card and use optical, but would rather not. Anyone done this?

The LG TV's have giant "G-SYNC COMPATIBLE" logos on the box and website. VRR over HDMI is supported right now on C9's and CX's on Turing cards, many of us are using it.

Just use hdmi to oled and then oled e-arc (hdmi) to receiver.
 
I've never bought a "Titan" class GPU but since Ampere's Ti replacement for the time being is the 3090, thinking back, no flagship Ti tier card has ever done me wrong. 1080 Ti was the best you could do for 2 years, 2080 Ti was the same. If you buy a 3090, you don't have to concern yourself with anything else released inbetween/above for a couple years and will be able to sell it (hopefully) for a good 60% of what you paid 2 years later. This is completely ignoring AMD (no faith) or the Corona/economic/supply circumstances that could swing it in either direction like it did with the 2080 Ti where used values = new.

I'm leaning toward the 3090 FE now.

GSYNC is supported on the LG B9,C9,BX, and CX. I believe it is also supported on the "boutique" models of OLED above those.

GSYNC over HDMI is supported on Nvidia Turing and Ampere GPUs (GTX 16xx, RTX 2xxx, RTX 3xxx).

LG worked with Nvidia to support HDMI 2.1 VRR on current Nvidia GPUs. VRR works fine over HDMI 2.0 already so there is no reason to think it would not work over HDMI 2.1.

The receiver I have only has ARC, will that be a problem? Also would a Display Port to HDMI cable be an option?
Click to expand...
Displayport is capable of carrying audio (up to 7.1 LPCM for sure, I actually do this. Not sure if it can do DTS:X/TrueHD/Atmos), but the cables don't always support it and it can be luck of the draw finding DP->HDMI cables that do.

I've had no luck with eARC going 2080ti > CX48 > Denon x4700h. It ends up killing the CX completely to the point that I had to pull the power before it would turn on again. ARC tho worked fine. I expect this will get sorted out between LG & Denon eventually.

I'm using this dp to hdmi adapter to send sound to my receiver now and everything is fine: https://www.amazon.com/gp/product/B07WD75HCD . You end up with 2 "monitors" in Windows but if you rearrange the second monitor to be in the top left corner, you won't notice it.

Thank you all for your help. I bought a $12.99 HDMI to Display Port cable and it works! Hopefully when my CX comes tomorrow it will still work :)
 
This is a mighty mighty long thread...Is the TL;DR consensus that this is currently the best 4k 40"+ option for gaming and movies? I've held off upgrading from using 2 HP ZR30w 30" 2K IPS monitors for like a decade now, mainly b/c I wanted a 4K monitor that would work great for photo editing and gaming. I don't take photos anymore so now it's just gaming, which makes choosing a lot easier.

Unless there is something totally awesome around the corner in Q4 this year or Q1 next year, I might buy myself one of these.

Thanks in advance for any answers.

Yes. If you're coming from the ZR30W to one of these, prepare to be blown away. It will be a major upgrade especially for gaming.
 
How is the text clarity on the 48CX due to the WRGB pixels? Can someone show a photo of text in notepad and Windows explorer on a 48CX?

I want to compare it to my current monitor / TV, Samsung UE43MU6100 which has a VA RGB panel.

Planning on upgrading to a 48CX if a text is not an issue and also upgrade to a RTX 3080.
 
How does it look in non-native resolution ? say you want to play some titles at 120hz at 1080p or 1440p instead of 4k - does it not look blurry ? I mean even with a 3080, you're not going to see 60FPS in Flight Simulator ...

1080p is crystal clear because it's an even 4:1 pixel ratio (it looks exactly like 1080p would look on a native 1080p 48" display, which isn't that great). 1440p isn't perfect but honestly doesn't look bad at all in my opinion.
