God damn! Seems like even the professionals don't clearly agree on length/performance standards.
I'll try this club3d cable, and if I still get issues I'll try an optical cable, and if I still have issues after that I'll just live with it.
Maybe I should just man up and move my tower on top of my desk.

The club3d cable did not resolve my issue with bf2042 locking up for half a second every 8 seconds or so :(.
I'm making major assumptions that it's the HDMI cable causing this however, I just can't think of what it would be.
Maybe I'll try an optical cable.

Hell yeah I want that pop! I crank up the saturation values when using RTX HDR and I could care less what the creator intent is :D
 
Wanting a picture that Pops is equivalent to using Ketchup on a fine ditch. Feel free to do so, but dont complain when more informed folks give you the weird looks. :D
 
I turn the saturation up a little in my LG OLED's game mode in it's OSD for SDR games since I found it a little dull compared to the other non-game picture modes. Then I use reshade to turn it back down to where I like it on a per game basis, along with tweaking a few other parameters. When I launch a HDR game and HDR game kicks in, it uses it's own HDR game picture mode so that saturation slider I adjusted higher only affects the SDR version of game mode. HDR games don't need the saturation boost from my experience, HDR range is very colorful. Some games have their own saturation slider in the HDR settings of the game though, so depends how you look at it.

More SDR games are able to use win 11 AutoHDR and now nvidia RTX HDR now, so their appearance is enhanced compared to default SDR game mode.

As if we care lol. Image quality is personal preference just like sound. Some want that bass boost cranked up, others do not. I bet you're also the type of person who would never use motion interpolation feature on your TV and whine about soap opera effect, and you know what? That's totally fine because it's your preference, not everyone has to like what you like. It doesn't make us any less "informed". Plenty of people here love using wide gamut mode for playing SDR games. To me, playing SDR games with it's default muted colors that are considered "accurate" is like eating your food plain and without any seasoning.

You are aware but - just an aside since you mentioned it. OLED is so fast you pretty much have to use some level of interpolation or low framerate video playback will look stuttered in some scenes. LCDs are so slow they hide low framerate media/video choppiness in transition blur/smear of their slower response time.

I'm very interested in seeing how samsung's new AI upscaling chip performs in the 8k 900D whenever some real reviews start coming out. It supposedly does great things for things for motion, like the ball in different sports content. It's a FALD LCD so won't have the same stutter look as an OLED on lower frame rate, panning etc. content, but theoretically they could someday put the same chip in more of the gaming tvs and monitors, hopefully even future QD-OLEDs.

. . .

From what I've been reading, nvidia's RTX HDR "autoHDR" can cause an appreciable performance hit. I've heard 6% to 10% compared to other "hdr injector" methods (some people report up to 20% but I haven't seen any confirmation of that). Considering that, some people are using special K (accurate to 480nit) , or Ilium Reshade filter to do their own 'autoHDR'.


Special K HDR Retrofit:
https://wiki.special-k.info/en/HDR/Retrofit

Special K vs. Native HDR

View: https://www.youtube.com/embed/p7J1KnTPa_c?autoplay=1

Excerpt from the video. Unless special K has changed since, this 480nit limit on most games might apply:
"I've tuned these values not to give you the most contrast or to give you the most peak brightness possible but to more accurately match the native HDR presentations in terms of average picture level, contrast, saturation, black levels, and leaving the peak brightness to wherever those sliders leave the peak brightness to - in this case, it's about 480nits. There is not much you can do about this currently with special K. This is the brightness you are limited at. It is still significantly higher than it will ever be in SDR if you're watching SDR in a reference grade environment - and it gives you some little fine tuning adjustments if you want a more punchy image or if you want a more contrasty, less saturated . . whatever you want the image."

"To go over it again, if you were to play a game like Farcry 3 which doesn't have a HDR presentation at all , without having to guesswork where to slide the sliders to - you can just use these pin values and know in the back of your mind that 'if this game had a HDR presentation, this is roughly what it would look like'. "

"There are some limitations with special K currently. Special K currently does not allow you to have a peak brightness whilst retaining the average picture level as dim as it should be, past ~ 480-ish nits and this is just a limitation of how the tone mapper and such works. There are some edge cases or different examples for example Halo Infinite - because the game's native SDR presentation has pixels that exceed 255 RGB value it goes past that and special K can extract this information when you inject it in and it will present it in a brighter format. Halo infinite with these settings goes above 1000nits whereas most games where I can't get that extra information will cap at around 480. You can go past this, obviously the slider is there you can do whatever you want. However for a reference image, the settings in the description are what you see on screen"

Reshade Illium HDR
(have to disable autoHDR in windows to use this method)
You install reshade with full add-on support (his stuff is included nowadays in reshade install, you have to check his shaders when reshade prompts you to download shaders), then you download his add-on from GitHub - it’s 2 files - autohdr32, autohdr64, choose the one that’s right for the game, depending on whether it’s 32bit game or 64, put it next to game exe. Launch the game, in reshade go to add-on options, click on auto hdr, check use hdr box, and optionally “use scRGB”, it’s a bit better quality of colors and banding, but doesn’t work with frame gen games. Restart the game, find Lilium’s inverse tone mapping, enable it. Then you’ll have to manually set peak brightness, tonemapping method, and gamma method. If game looks too dark, it’s probably linear gamma, otherwise use gamma 2.2 or srgb.

Then load Lilium’s hdr analyzer after inverse (load order matters) to check if peak nits are right, blacks not crushed or raised. You can set the MAX_CLL in the Ilium filter to what the game is trying to output (shown in the hdr analyzer in the top left of screen sort of like a fps meter), then change the target peak luminance in the filter to the peak nit of your screen (e.g. around 800nit on the older OLEDs).

Some games it messes up things. I think it’s because in scRGB mode it’s trying to remaster 8bit into 16bit and that doesn’t go well sometimes. In last epoch for example hdr10 works fine, but with scRGB some ui elements disappear.

You can also try Special K. It’s also very good, works almost the same, but remastering 8bit, 10bit, 11bit comes as an option for dx11 games, for both hdr10 and scRGB. So it might work better. It also has built in features to reduce latency, so it might help with stuttering.

PlasmaTVforGaming youtube channel: SDR enhancement info about the way he uses Reshade in SDR games on a HDR capable screen


View: https://www.youtube.com/watch?v=GXRLSc4soiY

HDR gaming on the PC keeps getting better. New Reshade and Lilium Shaders update. SDR HDR trick [Plasma TV for Gaming Channel, 5 mo. ago]

"We can get a nice HDR effect using Reshade for games that do not support native HDR, or AutoHDR from windows 11".
"Enable SDR black floor emulation. It's not losing any details. We can get a perfect black floor with a single click, you don't have to tweak settings up, down and do a lot of guesswork"
"There is a white point heading, max it out as bright as possible" (after following his earlier steps in the tutorial)

That or you could use windows auto HDR on supported titles, which is less than a 1% performance hit supposedly. Win11 auto HDR might even get a higher max CLL than 400 - 480. I don't know windows autoHDR's max accurate nits before it screws up the image (crush black detail, clip bright colors to white blobs, etc), or nvidia RTX HDR's for that matter. The nvidia RTX HDR performance hit is probably less of an issue on older/easier to render games but losing some fps might not be great when you are trying to scale the top end of your frame rate graph over 120fpsHz or 200fpsHz depending on your monitor, and you are trying to keep the bottom end of the graph from sinking down farther than w/o RTX HDR in demanding parts. Anyway, there are some options at least to get better than SDR using one of a few other methods, and those suites of shaders usually provide more tweakability if you want to micromanage more.

Performance hit seems to vary. Could be based on how much the tensor cores are already being utilized prior to running RTX HDR, or just how fast the GPU is in general like say a 2060 will suffer greater performance hit than a 4090, but I'm not sure. Either way this is a solution that is readily available at the push of a button (two actually since it's Alt + F3) and it just WORKS. For years now I've grown tired of dealing with games that have broken HDR implementations or no implementation and I can't be bothered to manually fix every single one of them every time. RTX HDR has provided me with what is essentially an instant fix for such scenarios and I am so glad it exists.

More options (like RTX HDR) the better, and it could get better performance eventually, and into the 5000 series. Hopefully dlss, frame gen, and rtx hdr will all continue to mature across generations.

For anyone wondering, I installed the beta version of the amd driver and it resolved my screen freezing in bf2042. I waisted all the time swapping cables for nothing lol.
 
Do we know what brightness figures the C2 has with ASBL disabled? Does it actually get brighter or not just dim as quickly?

I have all of that disabled on my C2, I could not deal with the dimming. It is no brighter, it just remains constant.

For sure. I'm kind of thinking of just using RTX HDR for everything. Gaming wise I mean. Closest to a one and done maybe. Have it set up similar to Plasma for Gaming's recommendations.
 
I updated my C2 42" to WebOS 23 and it could just be my imagination, but the input latency feels slightly worse. Maybe I need to reset the firmware and set it up again. :inpain:
 
If the 42 inch had a 1000R or more curve, I would have kept it. However, it appears that the LG 45 inch Ultrawide OLED monitor is better suited for my needs.

The thing is, it is not stretched at all, it is a proper 21:9 resolution. Also, it actually looks fantastic on the desktop and in games. You just have to make sure not to sit on top of it. 😊

Of course its 21:9, that wasn't the concern. Its just so few pixels for the size, which is better suited to 34". 45" is the domain of upcoming 5120x2160 UW's, IMO.

If I am understanding correctly, the LG Flex is simply a flexible version of the LG 45 Ultragear, which has a permanent 800R curve. (It is what I have.) If the C2 were curved, I would have kept it but, for me, a flat 42 inch unit was too large, overall, since I am 5ft 7 inches tall and therefore, my head does not come to the top of that screen.

3440x1440 at 45" is 82 PPI. It's the same pixel density as a 27" 1920x1080 monitor.

3440x1440 is also not a "proper" 21:9 resolution. It's an approximation. 21:9 = 2.[3]:1, while 3440x1440 = 2.3[8]:1. The proper 21:9 resolution would be 3360x1440, just like it should be 5040x2160 instead of 5120x2160.

That would mean all the 21:9 monitors are not correct but, close enough. However, the PPI of the LG monitor is something you will not notice, unless you are sitting on top of it. I sit back from it and at first, I was concerned I would not like the text sharpness but, I actually do not notice. I do run Mactype, since it is a RWGB monitor, and that helps a lot, although it appears good on my Ubuntu install as well.

Hi guys, im having some difficulty with ultrawide resolutions on my 7800xt and CX.

It wont display 2560x1080 properly (it stretches it) - until i enable GPU scaling. I dont wanna use that as its not as nice. What am i missing?

I believe you will need to use 2560x1440 not to have it stretch.

If you're trying to set an UW res for a 4K display, you'll want to stick to 3840x1600. That's mostly 21:9 and fits the width of the display natively.

Yep, otherwise, after he sets the screen to a 21:9 aspect ratio, he will get black bars all around.

If you want to keep it on display scaling, make sure aspect ratio control on the TV is set to Original. You can divide 3840 by your desired aspect ratio to prevent scaling artifacts. 3840x1620 is the same aspect ratio as 2560x1080.
 
Is it confirmed that you can infact disable ASBL on the C3 even though the options are removed in the service menu by using either LGTVCompanion or ColorControl software? I heard/read that they could somehow restore the missing options in the service menu to actually disable TPC and GSR?
 
Brightness bump on the C4 seems pretty decent actually.

1712702179912.png


Here is the C2 for comparison (RTings never tested a 42" C3 so can't compare that):

1712702214771.png


About 15% bump it looks like. Now if LG would just give it MLA...
 
Looks like it will match the PG42UQ then because it always had that brightness in reserve, LG was just conservative.
