HDR IS a little bit messed up.

[Yoshimatsu414]

I have an Acer ET430K. This is a HDR400 monitor and it displays HDR pretty nicely. Games like Gears 5 and Modern Warfare look amazing with HDR on but Assetto Corsa Competizione has a problem when HDR is enabled.

Colors in this game are displayed super over saturated and also the dark areas, like shadowed areas, are completely black, can't really make out any details. This even happens when HDR is off in game and it's only enabled in Windows Settings.

I've noticed something strange thar seems to fix the colors temporarily though. While I'm in the replay mode, if I click and hold mouse button 1 anywhere on the screen, the colors are display correctly. Once I let go of the mouse button, colors get messed up again.

Is there any fix coming for the HDR in this game? I'm glad it's a feature that was added into this game and I want to be able to take advantage of it correctly. Other games display HDR correctly on my screen so I don't think it's the screen of any other hardware.

you can adjust color and contrast in video options.

but yes, the default colors are very bad.

Sadly adjusting the colors didn't do anything for me. It just displays the HDR color maping incorrectly it seems. The brightness is dim and the colors looks overly saturated for me while in game. In the main menu is fine, but when in game, especially during replay or when a menu is on screen, it is all mess up.

interested in seeing which cables your using for your hdr setup?

And i thought i was the only one that thought cables matter....good point you made

The most overlooked piece of equipment in any setup...audio..visual etc

[Yoshimatsu414]

Yes I understand the cables are important too lol. I'm using the DP cable it came with, don't know what DP revision it is but I was assuming since it came with the screen and it's a 10bit display, they should include a cable that would be able to handle it.

I did have some issues at some point with some games where I would get the screen blinking to black for a second and coming back, this game was one of them. I solved that issue by changing the chroma sampling from 4:4:4 10bit to 4:2:2 10bit, the color issue still existed though either way. I also have an HDMI 2.0 cable and it's a 24Gbps cable. I tried that and the colors still displayed incorrectly.

Like I said before though, other games display HDR great! Like Gears 5, COD Modern Warfare, Resident Evil 2, Metro Exodus and Final Fantasy XV for examples. But I did have some games that give issues kind of like Assetto Corsa or sometimes they display fine and other times they don't like Rise of the Tomb Raider, Hitman 2 and Resident Evil 7. My experience with HDR gaming on PC has been kind of hit or miss with most games displaying fine but some others being broken with HDR on. I'm not sure if it's my display, AMD's drivers, Windows just being weird or the game itself.

Same issues here man. Just looks dim with HDR activated on ACC. All other HDR games are vibrant

[Frappete]

Same issues, ACC use a fake HDR, converted from SDR, from what i can see

HDR in ACC is garbage. Plain and simple. But then again, it's very poor in many games. Some handle HDR better than others. HDR, honestly is not a technology that is at it's peak yet. It requires a monitor with at least 600:1 contrast ratio or better. It also requires a high speed HDMI or DP cable. Lastly, some game devs have worked on the HDR feature of their game to optimize it. i.e. Motogp20. The menus don't look great, but the gameplay looks great with HDR enabled. Sadly, ACC is not one of these games. They have not put the time into it for it to look good.

Hi, did you solved the messed up colors on ACC? My game even with HDR off, gets darkened colors with absurd contrast.

[goblueteam]

for the really dark problems adjusting the contrast in the video settings helped me alot before that it was like a black mass in any dark areas i also keep hdr off on ACC i dont think it really helps at all

[Protonv5]

HDR in this game is very poor, FYI. Also, in general, for HDR you need a very bright monitor 600-1000 peak brightness

[Derek Moore]

It can get bugged. To fix it and see the proper HDR, make sure it's enabled in game, then quit. Make sure HDR is enabled in Windows HDR Settings but Auto HDR is disabled. Then restart your PC. Now simply start ACC and it should look like this:

Mine is extremely bright with hdr, I turn white balance to colder, it helps make it less bright, turn down saturation to 70

[Derek Moore]

Yeah, I switched the in game HDR color gamut from the rec2020 (which desaturated too much) to dci-p3, which would normally be too oversaturated, but I used the basic in game saturation slider to fine tune, probably to around 75 like you said, maybe 80.

[ANOK]

I forgot, also turn down the HDR UI brightness level to 50%
