damoninja Posted May 12, 2008 Posted May 12, 2008 Hi all, I'm using a TH-50PX70A panasonic 50" tv, resolution is 1360x786. I can use analogue on this display great, but i get a bit of interfernce from my nvidia graphics card. Anyway, it looks perfect apart from small lines you cant notice unless youre close. It shows up worse on some images. When i use DVI with this screen resolution, it looks like crap. It's as if its blocky almost, it's like the pixels dont line up with the ones on the screen which is fine for movies but absolutly crap for text, windows and what not... Its all distorted and impossible to read... If anyone can provide assistance id really appreciate it, cheers.

When you use the HDMI option, most likely you're not running in the native resolution of the screen. 1360x786 is not a TV resolution - its a PC monitor resolution - and is generally not supported over HDMI. You'll find you're probably driving the screen at 1280x720 (also called 720p) over HDMI, which is a standard high definition resolution. Because of this, computer stuff will look bad, but TV should still look fine (it's usually scaled anyway to suit the screen). There is not much you can do about this - it's a limitation of the HDMI implementation of your TV. Your alternative is to use another input type, not HDMI.
Yapab Posted May 12, 2008 Posted May 12, 2008 I didnt know this was the case, I thought DVI should be better than the analog DSUB? Maybe try playing with the resolutions? Hopefully I wont have this issue with my HTPC when I get a new LCD TV, I thought they would give crip PC text! Yapa
OzRob Posted May 12, 2008 Posted May 12, 2008 I thought DVI should be better than the analog DSUB? Maybe try playing with the resolutions? DVI is not the problem, it is HDMI. DVI is a PC connecter format and is used on monitors. If your LCD had a DVI socket then it probably allows the use of PC resolutions. HDMI, whilst it uses the same digital transmission format as DVI, is not implemented in the same way. It was designed as a consumer interconnect, not a PC one. Many TVs implement HDMI only for standard broadcast formats, ie. 560p, 720p, 1080i, 1080p. They do not accept other resolutions like 1360x768. While you can put a DVI/HDMI adaptor on a PC graphics card output, when it's plugged into the TV it must abide by the rules set by the HDMI socket of the TV. Bottom line is, a TV is NOT a monitor. If you want crisp, clean text via a digital connection then you either get an LCD TV which has a native resolution the same as one of the standard HDTV resolution (like 1920x1080) and use HDMI or buy a digital monitor instead of a TV and use DVI. SOME TVs do accept resolutions other than broadcast standard ones over HDMI, but this is the exception rather than the rule.
