I've been having a problem with Lightroom for at least the past few releases now (it's been going on a while, exactly how long I couldn't tell you) where the image on my second monitor is blurry. I'm using Loupe view in Normal mode and the image just doesn't seem to render sharp. The strange part is, I can click the image to zoom in and it will render at full resolution, and then when I click again to zoom back out, the image will stay tack sharp for a second or two and then it suddenly goes out of focus again. I can actually watch it go from sharp to not sharp after zooming out. The image is fine on my primary monitor.
I'm currently on Lightroom CC 2015.1 on a Windows 7 Pro 64 bit PC. If I can provide any additional details I'd be happy to.
Make sure that your standard preview size is large enough. You set this in catalog settings->File Handling. It needs to be large enough for your highest resolution monitor.
Hello, I checked this setting and it is set to Auto (1920px) which is the correct resolution for my monitor. I tried upping it to 2048 just to see if it made a difference but I am still seeing the same behavior. I also tried switching the preview quality from Medium to High without any luck.
Just to add some additional details, I was playing around a bit and I noticed that the primary monitor does exhibit the same behavior as the secondary monitor, but only when in the Library module. When in the Develop module the primary monitor looks sharp but the secondary monitor still looks blurry.
