Question

Corrupted colors in a Dual Monitor Setup

I'm running a dual monitor setup on my Win10 machine. I have a LG 27UK850-W 27" monitor as my 4K editing monitor and a Acer XF270HU 27" monitor as my 144hz gaming monitor. Both have been color calibrated using DisplayCal and a Spyder 4 recently. I get accurate colors on my LG monitor but corrupted colors on my Acer in LR Classic and PS when dragging the windows between the two workspaces. I can do this in real time, as soon as the window crosses the threshold between them the colors are all wonky.

I have tried adjusting the bit depth of each monitor with no noticble difference to this effect. I have disabled GPU performance in both PS and LR Classic with no no noticble difference to this effect. I have defaulted to the basic color profile to no effect. 

 

I'm on Win10, w/ a Vega 64 GPU and a i9-9900k CPU and running all current version of the CC apps.

The problem is the same if I start Lighroom on the LG then transfer it to the Acer. Then closing it and reopening it while still on the Acer results in the same colors. So no real change with that approach. I have assigned the sRGB profile as well with no result.

One important clarification first: You say it happens "as soon as the window crosses the threshold between them". Is that before dropping the image, or after dropping the image? This is an important distinction, because dropping marks the precise point in time where Photoshop switches from one monitor profile to the other.

 

Generally: Try to replace the monitor profiles (both of them) with sRGB and check again. This doesn't look like your "normal" defective monitor profile, it's more like the whole color management chain is falling completely apart. But start with the monitor profile.

 

Next, try a different driver for the video card. Either update or roll back. This is very specifically a gaming card, which increases the likelihood of bugs affecting PS/Lr.

I've had both programs start on each screen and trasnfer to each screen, it's still always corrupt on the Acer. I have tried changing the profiles to sRGB with no change. The GPU drivers are updated as well, with no change in the colors. I'm now on Radeon 20.1.3.

You didn't answer my question. Before or after drop?

Hi there,

 

We are sorry about the experience with Photoshop and Lightroom Classic on the Acer monitor.

 

Would you mind checking if the colors on the Acer monitor appear fine if the image in the application is opened directly on to the second monitor instead of the application being dragged over to it?

 

You can try to assign the sRGB profile to both monitors and check if that helps. Please check: https://www.lightroomqueen.com/community/threads/how-to-assign-an-srgb-icc-profile-to-your-monitor-windows.14070/

 

Regards,

Nikunj
