Does anyone knows why Aximmetry lowers the resolution by half? For example I have a LED wall with 4508 w x 1536 h pixels and when I open Aximmetry in the video outputs appear 2254 x 768 for no reason. The display/LED wall is listed correctly as a display on Windows and also on Nvidia Control Panel.
You have probably set the Windows display settings to Scaling at 200%.
