Is this correct. If I purchase a NEC 42MP4 that has a native resolution of 1024x768 and I wish to connect my HTPC to the plasma monitor. I want to get the settings so that windows is displayed in wide screen without distortion of icons, pics, etc and at the same time have TV programs in 16:9 aspect filling up the whole screen. Now I have done a few calcs on the signals that the NEC can handle and the only input signal that maintains the 16:9 ratio similar to the native resolution is 1360x765.


I have a PCI dvb-t card and does this mean that 720p (1280x720) would have to be scaled up to 1360x765 by my HTPC then sent to the NEC where it would be then converted to the pixel ratio of 1024x768?


The NEC allows for progressive video so does that mean that a 720p signal is going to look better than a 1080i signal or will the 1080i signal be re-sampled in the process and displayed as a 1024x768 progressive signal making for negligible difference between 720p and 1080i (720p up-sampled and 1080i down-sampled but 720p is approx native res of screen) on this monitor depending on the scaling circuitry.


Also can someone give me an approximate size on how big icons are on a 42" monitor with 1024x768 pixel plasma. do web pages and word etc look ok at a distance, ie easy to read and lastly what are some of the settings you would have to change to get windows operable at a viewing distance of 10' say.

This monitor accepts 720p (aka 1280x720p). This is pretty standard for 16:9 HD content (along with 1920x1080i) and should scale pretty well to the native res.


With static displays, 1080i may look marginally better than 720p when scaled to 768p. For action shots, 720p will probably look better than 1080i but that depends on the how well your monitor de-interlaces the input.


If I recall from my 42" plasma setup at home, your icons will be about 1" high at 1024x768. Text is small at 10' (unless you like eye charts). I'd consider using 480p (look for 720x480 or 864x480p) as an alternative.

With normal Windows settings (fonts, icon sizes etc), at 10', a 1024 X 768 plasma is going to be pretty hard to read. And if you send it a non-native resolution as you will have to do so that everything is displayed correctly, its only going to get worse as everything will be softened up. However, if you only plan to use the HTPC for video playback, you could run 1024X768 and get correct AR as the soft dvd players, Dscaler, etc have complete AR control built in. For all other PC use, I would either get a 42"ED plasma or a 50" HD plasma that has square pixels.

I was figuring that i would have to play around with text and use large icons etc but i am starting to think that this monitor is not going to be acceptable for my use. Because at the widescreen input ratio of 1360x765 there is going to be a number of scalings involved causing degradation in PQ and also at this resolution the refresh rate will be 60Hz in a region that uses 50Hz frame rates. So this will mean some sort of pull down method will be used and will not produce the PQ i would hope for in a AUD$10k screen.


the only other way which i would be happy using this monitor would be to feed it its native res which comes in refresh rates of 60,70.1,75,85 and 100.6Hz. But to do that i would have to make windows in 16:9 aspect at resolution of 1024x768, is there anyway of doing this, it should be possible? The HD6UY will have the same problem if i am not mistaken but it doesnt even handle a 16:9 PC input, so something definitely need to be derived if these monitors are going to be connected to a PC.
