I'm pretty sure that my setup is pixel-perfect (960x540), because there are no smudges and its really clear.
I'll say this with 100% certaintity only after I run some test patterns to very that (any ideas?).
Also on DVI, I get a pixel perfect match but only on 856x480, I haven't figured out the timings for 960x540 and I'm sure its just a matter of tweaking it.
Overall, the picture quality via 960x540 (VGA) and 856x480 look real close to me, so thats why I havent experimented much on getting the DVI 960 res. to work.
PS. I didn't figure out the powerstrip settings myself so I'll give credit to Koslian who mentioned them in another post. :)
