Hello everyone, I've never been able to use the HDR feature on my Cooler Master Tempest GP27U since the day I bought it. The monitor has the latest firmware installed, the graphics card drivers are up-to-date, the graphics card is an RTX 5080 and supports HDR, the monitor is connected to the card with a DisplayPort cable and the cable supports HDR, I've done color calibration with a Windows application, and I've enabled HDR in Windows settings and in the monitor's own settings, but when I open an HDR movie or game, the colors appear very dull (HDR setting is also enabled in games).How can I solve the problem?
