That is a question I have. VT30 is supposedly awful using VGA. Locked at 1366x768 just for one thing but DVI to HDMI cables should work in theory? My GTX 580 has a mini hdmi output as well. However think it´s only for audio? The cable I got is about 1 metre so not sure I will be able to test it.
But as in DVI output haven´t stumbled upon that during my research.. Maybe some HannsG monitor I read about several years ago.I suppose it´s in the PC monitor sections you would have to look to find that and a TV tuner. For some reason VGA is favoured.
As for monitors crapping out yes from reports from stores they do mention Samsung get a lot of returns. They do sell a lot of tvs so partly that but a lot of returns is for bleeding (non uniform backlighting for their leds. Their old plasmas had some peeling issue.
There is also a Sony KDL40W4500 that appear to self destruct after 2,5 years. If I would fanboy about a brand it would have to be Sony still though. All Sony monitors I have owned have never broken on me. Have a heavy dinosaur 29 inch Trinitron CRT that still holds after 15+ years. The Sony CRT monitors same story and my 6 year old Bravia 1 LCD TV show no sign of wear except for the reduced backlight and hardly any bleeding visible. They have been in the budget segment for some time but now they seem to feel they should do super expensive tvs again.
As for Panasonic they have shut down two fabrics or is in the process to. At least one oriented to plasma so they don´t appear to do all that well just like Sony. Flattest tv wins it appears nowadays which mean Samsung and LG.
