I recently purchased an ASUS PA32UCXR 32” HDR monitor (the one recommended by Greg Benz) to add HDR capability to my photography workflow and skillset. Upon my first dive into the Lr HDR space a couple days ago, I immediately ran into problems. As part of the troubleshooting process, I reached out to Greg Benz.
Issue description: Lightroom desktop (8.5.1) running on my Windows PC, the window is on the new 32” display in HDR mode and connected to an NVIDIA Quadro P2000. When the mouse enters into the image portion of the Lr window, the GPU load jumps to ~80%. At that point, any attempt to open or close the album pane on the left, or the edit pane on the right, results in no response. The GPU is still at ~80%. If the mouse exits the Lr window, the GPU drops back to ~0% and the requested action from above takes place. So, say I have a single image open in the window and want to switch from album to edit pane. I have to take the mouse out of the Lr window, come around to the right side, select the edit pane, and then move the mouse outside the window again to get the edit pane to appear (and the album pane to close).
I have discovered this problem does not exist with Lightroom web, and Chrome is able to handle HDR images properly. Ultimately, I have been able to solve the problem by moving the HDR display to the onboard Intel UHD Gfx 770 and moving my 24” SDR monitor to the NVIDIA Gfx. (i.e. I swapped the two monitors to the alternate Gfx hardware. As part of the debug effort I upgraded the NVIDIA driver to the latest version, which didn’t help. Capturing a screen recording on the HDR monitor is more challenging than I expected. I’ve tried three different apps so far. None of them support HDR, which apparently causes them to “shut down” the HDR pipeline in the recording process and then the problem I’m reporting disappears. I will try OBS Studio to see if that helps.
In the meantime, attached are three pictures for your consideration. They show the upper right portion of a Lightroom Desktop window with the Windows performance monitor to the right. In the first picture the mouse cursor is just to the right of the Lr window and normal shape and size. No Gfx issues. Next picture shows the cursor has been moved into the Lr window. At that point the cursor changes shape and size, and the Lr buttons on the right hand side are non-functional, except the crop tool. By non-functional I mean that the requested pane does not appear, even though the selected icon turns bright indication Lr know it has been pushed. At this point, if I drag the cursor outside the Lr window, it returns to its normal shape, the Gfx utilization drops to zero, and the last selected pane on the right side opens up. That’s the third picture.
