>1080 pixel black screen

[Glydric]

I'm using arch and pure X11 without desktop manager to show only video streaming, the display is 1280x800 but i want to use in portrait so i flip the rateo (800x1280) set rotation and ... nothing no video output
After a few tries i find out that 800x1080 is the maximum rateo that i can use while 800x1081 and upper gives black screen
