I have two monitors connected to my PC. Both are connected with display port cables.
One of them is an older 1920x1200 monitor running at 60hz.
The other one is a 4K HDR GSync compatible monitor that runs at 120Hz.
I have an NVidia 1070 video card with the latest drivers, and all Adobe apps are GPU accellerated.
If Lightroom CC is on the old monitor, it works perfectly fine. As soon as I drag it over to the new 4K monitor, the interface lags, it flickers constantly, and becomes completely unusable. However, if I go into the Windows display settings there is a setting for the new monitor "use HDR". If I turn this setting off, then Lightroom CC works absolutely perfectly on the new monitor. The old monitor doesn't have that setting, so HDR is always off on that monitor.
Please update Lightroom CC so that it works properly when it is on an HDR monitor in Windows 10.
