I've got this same TV. Got it half a week ago.
I've not been able to get the 1:1 pixels working with VGA

. I would like to know how? if any one knows? I've set the res to 1366 x 768 and played around with the clock settings on the TV but I get blurry pixels every few pixels across the screen. Up and down seems fine but. It's like if you set the wrong Res on a PC LCD monitor. I've not bought a DVI to HDMI cable yet so don't know if I will have same issue? Will this give me 1:1?? I have a nvidia 6800GS graphics card on PC. I would perfur to use Video input instead of HDMI for my PC as I want to use the HDMI port for my HD cable TV some time in the future.
Some info on my TV for you .
Get hissing noise from speakers. Even if I have volume to low. Ended up plugging PC speakers into Headphone socket for my sound.
1 dead black pixel half way down the screen, but not a problem.
Only one HDMI input. Means I'll have to end up buying a switcher box. They are mega expensive I found

.
Inputs share the same Audio inputs. Means I'll have get a Audio switcher. Bit like the one on boxrick's picture I guess.
TV does not seem to auto switch between... if TV program is in wide screen or just normal screen. Have to press the Zoom button to the correct ratio or I get short fat people :D.
2nd Scart is not RGB and get a poor picture with it. 1st Scart is better. Got my Digi Freeview box plugged into it. Not a too bad of a picture. Colours maybe not as good as a normal TV but almost there. Then again I say that about LCD TV's that cost £700 British pound.
I Not tried HD yet. So can not comment on that.
Funny thing I read in manual. Max lifetime of back light 50'000 hours. wow :D Let me get my calculator out. Say I have TV on 5 hours a day. That means the backlight will last 27 years

How do they know these things?
So if any one can answer the 1:1 pixel problem? thanks a lot.
