For 1440p, the recommended size is 27''. Going higher may result in lower PPI, therefore I'd not suggest.1)27 inch is a bit small for my liking is there any 32 inch ones would be good
A 32'' display would be better with a 4K monitor, but you'll need a greater budget.
ASUS TUF B850-PLUS has a total of 17 USB ports.2) need to have at 3 usb on the back for my keyboard mouse & led light(or two with a monoitor havinga usb port)
