I’m guessing that doing this will actually make your color look too dull and washed out because your monitor should actually be using rec709 coordinates in all non-HDR modes.

It is okay if I use USB-C to HDMI via a dongle.

For instance, to get 21:9 aspect ratio back, I scale to 3440 x 1440.

Im running this on a 2080 ti with a Predator X35 monitor. Free Sync Extended smooths 4k game play on my Windows 10 Nvidia 2080 Rig. The desktop isn’t supposed to be seen with that gamma profile on macOS or Windows. I bought an HDR10 supporting LG Ultragear IPS monitor recently. However, I am pulling my hair out trying to calibrate(HDR settings) this thing and my LG C6 OLED. I just installed the firmware update in order to correct the 'green' issue over DP, but now the HDR is a mess. When HDR 10 is passed in it'll show a popup with something like 'HDR' displayed and there will be specific display modes for that type of content. 3) LG 27GL850 - A balance between resolution and frame rate. Because for some reason, LG wants to keep the black stabilizer at 50% locked. I'm trying some HDR10 content MKV files for testing purposes. I recently purchased 2 Asus ProArt PA32UC monitors that support HDR. When Windows enters HDR mode, OS will convert the non-HDR content (such as desktop, common apps) into sRGB mode. Hdr looks washed out lg monitor Actually it should be the exact opposite, colors should look much more intense and have more saturation, the enviroment should be sharper and more clear difference on black and white.
