Ughh, this is endless! I've installed the latest drivers form NVIDIA, as adviced, and although improvement was present, its certainly not acceptable.
I can now use the NVIDIA Control Panel, which is great, to create my custom resolution (1680x1050). Acording to said control panel, my drivers support the resolution I created, so they asked me to test it.
I did so, and it looked fine except the image doesn't quite fit on my screen, I've tried PowerStrip's image rescalling and resizing tools, to no results. I've tried my monitors auto-sizing option, it doesn't fix it either.
It's rather easy to notice the upper-most tab of WMP is not whitin range.
