Here are my specs and details:
- The monitor is a BenQ GL2450 whose native res would be 1920x1080.
- The OS is Win 7 x64.
- The Mobo is a Gigabyte F2A88XM-D3H with integrated Graphics (Radeon HD 7480D).
When I select the 1920x1080 resolution, yet my BenQ immediately reports:
"Nonpreset mode, recommended resolution 1920x1080."
I've installed Catalyst control center, installed the mobo drivers, updated the graphics drivers, nothing helps to solve this.
Windows and Catalyst both report 1920x1080 being set, yet the monitor seems to refuse to go into that mode. In reality the resolution looks to be something funky like 1700x1200, as the right portion of the monitor shows a fat black bar, and the taskbar is half-way cut off. Lower resolutions aren't correct either, having different parts of the screen cut off at times.
It's also listed as a "non-PnP monitor" under hardware manager and refuses to be anything else.
Could the cable be at fault? It's connected to the PC via a VGA cable, the monitor's input says D-Sub. Do I need to use DVI-D instead? Because I just set up this computer for my grandpa and we don't have one here, only VGA, and would prefer not having to buy one if that's not the source of the error.
