Windows 10: "SDR content appearance" Slider is missing.

So I have a laptop connected to a samsung TV via HDMI, but after 30 mins or so, the TV screen becomes dim and dark. I followed one of the tutorials on the Samsung website and it says I need to adjust the "SDR content appearance" slider to get the right balance, but that option is missing and I don't see it anywhere, can anyone help me with this?I'm running Windows 10 Home 64 bit, my product is a HP Laptop 15-ef1040nr and the processor is a AMD Athlon Gold 3150U with Radeon Graphics 2.40 GHz with 4.00GB RAM.

Windows 10 HDR & SDR

Hi i would like to know is it possible in windows 10 to watch a HDR content on a SDR monitor so it looks like a proper SDR content.

Because more and more movies is HDR and on my HDR tv it is all great even in windows playing HDR content AND SDR content on HDR screen works properly. Problem is when playing HDR content on normal pc monitor picture is way to dark contrast is all wrong.
Yea i can fix it in some way in the players with the brightness and gamma sliders but it still doesnt look like the original sdr content.

I would like to fix this issue because soon al my video content will be in HDR but i am not always vieving this on HDR screen. Sometimes i would like to watch it on my phone or my pc or my friends house and in all those places with SDR screens looks way
worse than a normal SDR content.

 

SDR content brightness revert to 0 after monitor HDR status change

I'm currently running windows 11 OS build 22000.282, using Odyssey G9 monitor from Samsung showing as LC49G95T in 'Settings-System-Display-HDR'.

After use HDR option turned on, my monitor blacked for a few seconds, then at the top left corner it shows 'DisplayPort1 (HDR)', then my screen slowly getting dimmer and dimmer (while I'm at desktop and only Settings opened). Changing SDR content brightness slider is indeed working, and I can make SDR content looks as bright as before HDR turned on. But if I try to launch a game doesn't support HDR or Auto HDR, for example Rainbow Six: Siege, my screen blacked few seconds and top left corner says 'DisplayPort1', my game looks normal as in SDR mode.

Then when I close the game, my screen blacked and it goes back to 'DisplayPort1 (HDR)', and slowly getting dimmer and dimmer, the brightness at this point is the same as the SDR content brightness slider in HDR settings moves all the way to 0.

When I check in the settings, the slider keeps at the spot last time I configured, but if I move it a little, the brightness changes to set value. This option is currently broken for me, as every time my monitor goes from non-HDR to HDR, I need to move the SDR content brightness slider again to make it work.

 

SDR Content appearance setting issue: dark screen after each user session change

Hello,

After each user session change, that means every day since april 2018, I have to adjust the SDR content appearance setting because this setting value is not taken into account at logon. The result is a dark screen.

The SDR Content appearance slide remains at the correct saved value (around 60% in my case), but I have to touch it (every day) to have my screen at the correct SDR brightness.

It is an issue that has last since Windows 10 build 1803 when HDR capabilities have been introduced in Windows 10. I just reinstalled Windows (last version) on a blank disk and I still have the issue.

It is a very annoying bug and I don't understand why it has not been fixed since april 2018. It is not listed in the known issues:

Thank you for help,
