My 49-Inch CRG9 monitor (model LC49RG90SSNXZA) has a picture-by-picture (PBP) feature which I have used with a Lenovo PC for the past 18 months with only one minor problem (the right side won't come out of sleep mode but that's not the purpose of this post). I recently purchased a new Lenovo ThinkPad P1 Gen 4 (model 20Y3003TUS) that I use with the Samsung monitor in picture-by-picture mode, but now the right side has a gray tint while the left side does not. Do you know how I can get the gray tint to go away?
I'm connecting the laptop to the monitor using a ThinkPad Thunderbolt 3 Dock (model DBB9003L1) and two DisplayPort cables.
I upgraded the monitor's firmware with this file about 4 months ago: m-RG949CCAA-1007.2[2D8D].bin
