Re: 3090 FTW3 Ultra - Experience & Tips 2020/10/20 11:46:02 (permalink)
I have been participating in this topic which has lots of good info for 9 series TV
https://www.avsforum.com/threads/2019-lg-c9%E2%80%93e9-dedicated-gaming-thread-consoles-and-pc.3123168/page-162
 
there are some nuances between 9 and X that will make it hard to compare experiences 1:1
 
You can request a beta firmware to be sent to your TV, or you can update manually with the correct tools using the engineering menu. The official update will not be pushed until November at the earliest. The update they push out seems to be 4.9, while engineering menu gives access to some version 5 betas.
 
Right now it seems that the updates they push fix the G sync issues with 30 series cards, but may introduce some with 20 series cards that worked fine on the old firmware. I believe this is the reason why they are only pushing it to people who requested it who have 30 series cards in hand.
 
I requested my firmware update over LG chat last week, was told about 5 business days. Still no update on my end as of this morning. They asked for my personal info, as well as my TV serial number and wired mac address. It seems that to push the update they want you connected via ethernet, not wifi.
 
Hope this helps. I will update more when I receive the update to my E9.

Any good ones that you can recommend?

HDMI cable? The 10 foot one here worked great for me: https://www.amazon.com/gp..._s00?ie=UTF8&psc=1


 
I will be looking at trying this same 10ft cable soon when my 3090 gets here, fingers crossed that it works out ok here as well. The 6ft cable from Monoprice that everyone recommends I'm sure works fine, but it's just a little too short for what I want it to do unfortunately.

New to this thread, so I’m just starting to explore this with my LG 65C9AUA. Apparently this can support 120Hz 4K G-Sync with a firmware update to 04.90.33. I’m currently at 04.80.03 and I don’t know how to get the required update. Another big problem is my inability to get a 3090 FTW3 Ultra, however I’m hoping my notification will come soon and solve that issue.
 
Will this firmware 04.90.33 update be available online?
 
On the topic of cables, I had a heck of a time getting my 4K UHD player to play HDR content without “sparklies”. The only cable I found that works is a “ECHOGEAR 8ft Braided HDMI Cable - 4k & HDR Compatible” I got from Amazon. It’s supposed to support HDMI 2.1 (48 GBPs), and I can say it definitely solved my sparklies issue. Don’t know if anyone else has tried this cable, but it’s the one I’m going to try when I can get my 3090 and figure out how to update my C9’s firmware...


You have to contact LG and request the beta update. You have to give them your serial number and wired mac address and they'll push the update to you.

I'll add a section in the first post about cable results.   so far I had 5 failed cables, and only 1 working.
 
Please share your specific cables that are working or not working and I'll update the OP.  For it to be "Working" it means ZERO issues. every game works, windows runs 4K full color with 32-bit 10 bpc @ 120hz,  there is never any flicker, all games launch FULLSCREEN and run without issues, artifacts.



I would put another section with the "Mostly Working" title. For example, the 30 foot optical 8k monoprice cable mostly works for me. All I need to do is turn "Instant Game Response" mode off and on before playing a game to get g-sync to work properly, everything else works perfectly fine. And it's the only long optical cable that I found that works that well.

And here I thought I was working around the damn black screen flickering that is getting worse on .26. So, bit of a back story - after updating from .25 to .26 I wasn't getting this issue. Then it started happening only sometimes when I turn the TV on, and I found that turning HDMI UHD Deep Color on and off fixed it, then later I had to do it twice. This morning that didn't work at all, so I tried another suggestion of turning off the Instant Game Response and turning it back on. It still flickered.
 
This might be a byproduct of me starting to run my 3090 working folding@home full time over night - these drivers are still spotty, and I sometimes see that afterburner is all funky town graphics (indicating a driver failed and recovered).
 
Just for shrimp and giggles, I am going to get a new cable to test - I still think that it's a driver and or TV firmware (since .25 worked fine), but it won't hurt to have a second 8K cable.


Dang, that sucks. Thanks for reporting it though. I'll stay on .25 for now then. Maybe things will be better in .27?


Are you using a multi monitor setup? And if so have you tried the nvidia hotfix driver?

I'm going to be trying out these hotfix drivers later tonight. The flickering it mentions might just be the fix I need, since technically my AVR even as an audio source counts as another display:

As a matter of fact I do. I have two ultra wide monitors along with the CX. I'll give the hot fix driver a test in the morning. Thanks for the heads up on this one.

Nope, the hotfix drivers don't fix it for me. It actually seems a LOT worse for me. Hopefully that new cable will be the fix. Ordered that 6ft Monoprice one that was listed as working a few posts up.
 
Edit: Can't get the screen to stop flickering. The menu overlay from the CX flickers as well when I lose video from the PC. Setting 4:2:0 instead of RGB seems to have fixed it. Strangely, setting ANYTHING other than 4:2:0 8 bit will cause the constant flickering as well. I'm really hoping that it's just the Zeskit cable that started not being able to handle 40.1 gbps.
 
Edit: This morning I turned on the CX after having my 3090 crunching folding@home units all night long (left it at 4:2:0 8 bit) and no flickering!. I felt froggy with a new idea, so I moved the Zeskit cable away from power plugs and the 3090 and instead routed it over the top of my big ace computer case and added four EMI chokers. I then set RGB 10 bit (Gsync and HDR were still enabled) and I am NOT getting that constant flickering, or even occasional flickering. So it was EMI that was causing a reduction in the usable bandwidth of the cable - something that could also be fixed by using a $200 fiber optic 2.1 cable, or this $25 Zeskit cable with ~$6 worth of EMI chokers and unsightly routing (which I'll try the old routing with the EMI chokers later).

For #7, "Section 3, override to NVIDIA color settings and choose 32-bit, 10 bpc, RGB, FULL. and apply"

What is the purpose of this?

The earliest drivers from Nvidia defaulted to 8bpc & Limited range, so you would not be getting the full HDR color capabilities of the 3000 series card and TV/monitor via HDMI 2.1.  if the default has it gray'd out and it's the same 4 settings, then you are OK - You don't have to override, but early on it was not correctly identifying the TV's full capabilities. 
 
essentially, this LIMITED vs FULL option lets you go FULL deep black levels, where limited stops going darker before the TV's capability. it gets technical but you can quickly google if you want to know the finer details of it.  but basically - if card & monitor can support, you want FULL.
 
And the 8bpc vs 10bpc has to do with gradients of color and total color pallette - 8-bit file works with RGB using 256 levels per channel, while 10-bit jumps up to 1,024 levels per channel. This means a 10-bit image can display up to 1.07 billion colors, while an 8-bit photo can only display 16.7 million.  so essentially 5x more colors are possible just by simply changing this setting.. in real-world, things will have better gradients and look smoother.

Nickvdm - it would help a lit to have a link or a model number, I find a lot of different belkin HDMI ultra cables. and all the ones I see do not support 4K @ 120hz 48gbps... so that's good if it does or if you know specifically which one works for you.

Re: 3090 FTW3 Ultra - Experience & Tips (for LG CX OLED users) 2020/10/21 19:54:58 (permalink)
It's been a couple days for me since posting last. Figured I'd share some more experiences. I don't know why, but the black flickering associated with instant game response is completely gone now. The first time I disabled Instant Game Response, the flickering went away. But then apparently I lost my gsync capability. So then I tried the recommended approach of turning it off then on again right before launching the game. It worked! But then I left it on and have played a number of different games over the past couple days without issues with the TV even after involuntary reboots (I double checked... it's definitely on in the settings, and I see the popup when I launch a game)
 
But I am experiencing instability with my PC. I have 9900k with the 3090 (MSI Ventus) and it's powered by a HX850i and have two monitors the CX and a 32" Samsung 4K. But with spontaneous reboots while gaming, it really smelled like a PSU issue. But 850W is definitely fine, especially with the very efficient Corsair HX. I never bothered hooking up the diagnostic cable (mini USB into USB header) and then I can monitor everything about voltages (in/out), peaks, temps, fan speeds etc. I can say that during benchmark tests and throwing the kitchen sink at it, the PSU barely broke a sweat. The biggest peak I saw was in the 560W range. So the PSU is fine. Don't let people convince you to buy a 1000W+ PSU to power the 3090 beast. 
 
What I actually think is happening is the card is overheating and forcing a reboot. While monitoring temps, I'm definitely seeing results in the high 70s... and it looks like it might trip at 83C (according to Afterburner settings -- stock values). I'm watching this closely because normally when I'm actually playing a game, I'm not really watching for temps -- and when it trips, it's too late. But it happened twice last night. It seems to happen after playing for about an hour or so... it seems the card needs time to heat up gradually.

So that's my next struggle. I haven't played around with underclocking it yet -- I feel like I shouldn't need to especially for this price. I have the latest drivers as of 3 days ago. No Man Sky seems pretty fragile with stability compared to Assassin's Creed Odyssey -- both 4K Ultra, definitely getting ~90FPS in both games which is a joy, but both games have rebooted my PC.

Sounds more like a power supply issue.

The HX850i is on the known good list - though it's possible that it has aged and is not delivering the same power that it was (or the PSU is getting too hot and shutting off (bad PSU fan/fan blocked from getting air in)).
 
As to the OP - try setting the temperature slider to max. It raises the power slider too, but the temp goes to 91 instead of 83. You can always set a more aggressive fan curve as well, to keep the temps lower.

I'm overclocked to 5.1ghz on a 10900k and using an Asus tuf 3090. Autocad and extremely heavy rendering via v-ray and revit. I've been working 9 hours striaght and the weekend I ran flight sim 2020 maxed out for 6 hours and I have yet to experience any issue with the GPU. In my living room I have a 65" 4k samsung. In my office I have a 43" pg43uq driving at 144hz via displayport. My power supply is an evega 1600watt titanium. Yes I know I don't need a 1600w but it was on sale for the same price as a 1000 watt gold. If I were you I would try a different psu for testing. Also do you have custom modded cables? I have found that sometimes with custom cables the gauge is slightly smaller than stock on specific conductors and all it takes is a gauge smaller or a bad pin crimp connection and you will build resistance. It may appear power is okay but you won't see that in watts. It would be in amps. After the pc reboots shut it down and really feel the gpu cables and make sure they do not feel hot.

I swear the very first thing I did was install the latest Nvidia drivers. But somehow they didn't stick. I installed them again, and now most everything is fine, except for my embarrassment. I did an overnight test of AC:Odyssey where the camera was just spinning. Temps on the GPU were stable at 68C. PSU was level at 515W (when actively playing I've seen a peak of 560W). Corsair is fantastic and my last set lasted a decade. My HX850i is barely a year old.
 
That said, my big mistake in testing was that I kept looking at No Mans Sky. It just crashes like crazy (freezing up). Usually within a couple minutes of firing it up. So I guess there is something else going on there. (Maybe Gsync related)... or just a bug in the game code. It didn't crash at all with the 2080 Ti. It's the game I've been actively playing. 
 
At least all my firmware is updated and Windows 10 is now on winver 2004, which was a major windows update.

Hey all I have a 55CX with a 3080 so hopefully you all can help me out. I have been noticing some minor artifacts if I go over 100 fps. If I set a limiter for 100 fps everything is all good. I did apply the LG 3.11.25 firmware update manually and everything works fine, no flickering or black screen, GYSNC working. But for the life of me I get annoying micro vertical artifacts showing when I'm gaming over 100fps. All my setting Windows are set for refresh rate of 120 same goes for NVIDAI CONTROL PANEL. I have tried everything from having vsync on/off but I can't seem to go over 100fps without noticing those artifacts? could I have a bad card? My temps are fine within 50-60 degree, using all 3 PCIE power so power is not issue. I tried playing with OC setting plus just stock setting still the same. Games I have seen it are in Wolfenstein New Collosus, Metro Exodus and DOOM. So if anyone have these games can you  play 4k while playing at 120fps?  Could it be my hdmi cable? I play Destiny 2 and I'm getting over 120fps 4k max settings no issues, so any help is welcome thank you. Also notice if HDR is not on these 3 games work fine. But Destiny 2 has HDR and is working fine, so I'm stump. 
 
Edit:
I reseated my card made sure it was very sturdy and connected, seems to be fine now as well. False Alarm

Happy to report that I installed version 5.00.03 on my LG E9 via USB, and now it works flawlessly in 4k12hz + HDR + G sync. Very easy to update using a USB stick and the download from this link for C9 and E9 models

So I think I resolved my stability issues... I bought a HX1200i to replace the HX850i -- the 850 is only a year old and is likely just fine. When I took it out, instead of using a single cable to power both GPU slots, I used two separate cables. Maybe that would have fixed my original problem? I only have a couple hours of stability since the swap -- so I'll need to game some more. My biggest power spike at stock card settings is 576W paired to a 9900K. My leading theory is that the 3090 has wild mood swings and even a rated power supply might not be able to adapt fast enough. Hard to say without more testing....

In any case, the 2080 Ti never had issues being connected to the 850 with a single cable (two 6+2 pins, one cable) though it draws less power. 
 
Also these are the cables I'm using without issue: https://www.amazon.com/Cable-Matters-3-Pack-48Gbps-Support/dp/B081NXV3ZR (I nearly returned them before realizing the Instant Game Response was responsible for the black flicker -- though it's completely gone now and it's always on. So no idea what changed).

Fire up a game with NV control panel running to make sure that the TV keeps gsync enabled once the game is running. If so then you're good to go. :)

One more tip - I've been having issues coming out of sleep, and I believe I narrowed it down to Philips Hue Sync app causing the issues.   I discovered this while trying to watch a video with light sync and it crashed my PC one time, tried a different video and it was in a bad black flicker, tried a few more times in different apps and video content and continued to get crashes, reboots, flickers, total loss of video signal.
 
for those not familiar with this app - it uses your video & audio signal to control Hue bulbs and adds the ambient room lighting.  it injects itself in  the signal stream like an overlay.
 
I've now uninstalled Philips Hue Sync and for the first day in weeks my PC woke out of deep sleep.  I think philips is aware of issues because they rarely update this app and over the past two weeks they had 3 updates.. latest version came yesterday made things worse and that sparked my thought to test and remove it.

Update to confirm for those that may be interested: I'm using the 3m cable from Zeskit mentioned earlier in the thread with no issues at all up to 120Hz on my LG CX65 & 3090 FTW Ultra. (latest hotfix drivers, manually set the profile/resolution/refresh, latest XOC BIOS on the 3090)

I have HUE as well, but I never hooked it up to my PC -- I just use Alexa voice commands to drive it. I found that the software on HUE is pretty bad (and SLOW). Btw, my GSYNC is on all the time -- I have it set for both windowed mode and full screen mode. I like to play games in borderless window so I can multitask other things. I had a lot of issues with full screen on the LG (via HDMI)... especially when you are playing at lower resolutions which is what I was doing with the 2080 Ti before I got the 3090. Now it's less of an issue because I play at 4K in everything.
