I tried to work with lightroom developer mode but when I select an image it still stays on the grey screen instead of showing the image I want to work on. I tried disabling my gpu but this did not change anything at all so I re enabled them again. I am trying to figure out what the problem is but all I can figure out is that maybe it is because I started the trial first to see how it works.
This might be caused by a defective monitor profile.
Try setting the monitor profile to sRGB (use Adobe RGB if you have a wide gamut monitor).
Restart Ligthroom after changing the monitor profile for the change to take effect.
If this fixes the problem, you should ideally calibrate the monitor with a hardware calibrator. This will create a new monitor profile that accurately describes your monitor.
