Re: HDR issue on PC

This issue has just gotten a lot worse for me. Previously the game would work (most of the time), but leave me with a black screen on exit. Now (since upgrading my Nvidia graphics driver to 451.48) I just get a black screen, and there is no way to play it (except for windowed mode, which is still a crapshoot tbh as the game keeps wanting to fullscreen itself and reenable DV). I hope this issue gets fixed eventually... even if we had the option to switch to HDR10 since the DV implementation is broken, that would be better than this.

EDIT: I found a workaround that at least lets me play, and DV is working. This is with an Nvidia 2080Ti and an LG C9. What I do is set the game (in its config file) to 3840x2160 resolution (with GstRender.HDRMode 1). I then switch the desktop to a non-native resolution (e.g. 2560x1440) and launch the game. This results in the game working fine at 4K with no black screen (no clue why it works, but it does - every time).

When you exit the game you will still be left with a black screen instead of a desktop - as has always been the case, due to the game not disengaging DV properly. If you have another screen attached, you can switch to it (hold Windows key and press P twice to switch from a secondary display to a primary one) and then disable/reenable the graphics card via Device Manager to avoid having to reboot the system.

Situation still sucks, but at least this is a functioning workaround for me.

Great post, thank you for posting. I had a 'working' workaround for SDR already, and somehow got it in DV with a normal image once or twice by messing with alot of things. But your info is correct.

Very useful windows shortkey as well that I didn't know yet.

Edit: do you also have spots / sparkles on the screen this way?

Edit2:

- The weird spots on the screen are caused by using resolution scale under 100.

- Ini file is documents/Need for Speed Heat/settings/PROFILEOPTIONS_profile (incase someone was missing this info)

- Works if you want to play in 1440p as well, windows has to be in 4k then.

- Works only for me if FullscreenScreen 1 and FullscreenMode 0, FullscreenMode can be set to 1 unwanted if you switch screens / test workarounds/ alt enter.

- Not sure what H3llf1re does to re-enable the gfx card. After playing the game, things are still not completely normal and it seems to be that Nvidia colour setting dynamic range is changed to full. Changing it back to limited will trigger the black DV screen. Reboot will fix that.

It's almost November 2020, and I've been pulling my hair out over this as well. I've spent hours searching for answers and in the process of trying suggested workarounds, I've actually broken other games. Very frustrating. Thankfully I've been able to resolve those other issues, but the Dolby Vision black screen remains.

I can at least get NFS Heat to run without triggering Dolby Vision by turning Deep Color mode off in my TV settings (LG C8). But as soon as I try and switch it back on, even after exiting the game, it triggers Dolby Vision and I'm stuck with a black screen.

After several reboots of both the PC and the TV, I'm not exactly sure what I did but somehow things are back to normal. If this is what I have to go through every time I want to play this game, then that's ridiculous. I wish I could get a refund but I'm past the date.

Was thinking to give this game a go in 2021 to find out its still as broken as it was when it came out(talking about a worthless company). I was part of the NFS franchise since NFS 1 1994 so for a long time and to see EA destroying game franchises like this it hurts they killed NFS, Mass Effect, Anthem, Medal of Honor and many more. Too bad we cant uninstall EA like we can uninstall the broken things they call games.
