I just bought a new HP Omen 32 monitor and it is capable of 2560 x 1440. But in Windows 7, 32 bit, it maxes out at 1920 x 1200 when I go to the display tab in the Control Center. My NVidia display also supports 2560 x 1440. How can I get it to display maximum resolution? How do I talk to my video driver? Thanks.
I just ran into same problem but think I found a solution.
In NVIDIA control panel -- display -- change resolution, select omen monitor, then click customize. Then on pop-up window, choose create custom resolution. You just type in 2560 and 1440 respectively, and let it run a test. Mine shows test successful and allows me to keep this custom resolution. The next time I try to change resolution for the monitor, there is this 2560 x 1440 option showing up.
I am no computer expert but this works so far. Good luck! (probably belated..)
