I just finished testing a Dell Ultrasharp 2007FP on LX2,LX3,LX4, and LX5. A 1600×1200 IPS panel made by LG.
At first LX5 didn’t work, then I realized by default, LX5 is set to 1920×1080, switched to 1600×1200 and it started working.
If anyone has the monitor, to avoid any scaling, make sure to set it to 1:1 pixel mapping. The 2007FPb also works, it’s the same monitor, just sold to businesses.
