A friend and I just bought two LG 42" 1080P lcds, trying HDMI via the 8800GTs we have results in a grainy image, very hard to describe, I will try get a picture sometime of it. I am using a Palit 8800gt with has a hdmi port on the back, so its hdmi to hdmi on the tv, his line goes through a dvi-hdmi adaptor.
On both our computers the image is said to be 1920x1080 but its far larger than the screen, none of the scaling options fix it, and to get the screen to fit exactly you end up needing to go down to 18xx X 9xx something (Can't quite remember), even at this resolution everything looks shocking.
After a little research it seems like its a nvidia driver problem, but with nvidia being so highly reccomended with freeview I would have thought it would be a well known problem to the Geekzone community and myself considering I have spent a fair bit of time recently looking around geekzone as I plan to put together a proper HTPC, I admit I only had a quick search around the forums for it, but didn't find any traces of people with the same problem
Over VGA its look great, I've played a bit of COD4, Crysis, Trackmania on it and its great. It would just be useful to be able to get hdmi working for the future with BR/other protected content on the horizon. Over VGA the resolution is 1920x1080, same as what it is over HDMI, but it does no scaling, fits perfectly on the screen, and looks crisp.
Has anyone experienced the problem as well and found a fix?
I am going to try get hold of an ATI card soon to try test if that works fine on the LCD. It may be the screen, but if VGA works perfectly then wouldn't that mean it has the right pixel mapping and stuff to work with PCs?
