I have a Toshiba PORTEGE X20W-E laptop with a USB-C hub that can display to a 1080P monitor via USB as a dual monitor.
I want to buy a larger 27inch QHD 1440P monitor.
How can I find out if my laptop can output 1440P?
Can't find anything in the manual that specifies the resolution.
I find that 27inch with 1080P isn't sharp, especially when you have the laptop next to it displaying 1080P on a 12.5 inch screen.
Find out what your graphics card is, find specs for said graphics card, you should have your supported output.
For example yours is:
