I have a Hitachi HD-Ready HDTV (1366 x 768 native resolution) with two HDMI input ports. The manual says that the input signal when using HDMI cable could be up to a maximum of 1080p/50Hz or 1080p/60Hz. I have just installed a PlayStation 3 and connected to the above HDTV via HDMI cable version 1.3. When setting up the PS3 I am prompted by the menu as to the resolution I want: 720p, 1080i or 1080p. Based on the HDTV manual, I set it to 1080p. My son says that it should be set to 720p as that is the Hitachi's native resolution. I am confused because the specs for the HDTV are 1366 x 768. Need your advice on this. What resolution should I set it to? Best wishes,--George

Hi George,
Your son is correct. Set the PS3 to output 720p, because your Hitachi's stated native resolution (1366 x 768) is closest to "720p" which means a resolution of 1280 x 720. If your Hitachi had a native resolution of 1080p, it would be 1980 by 1080.

It's always desirable to have the incoming video signal as close as possible to the set's native resolution, so your Hitachi doesn't have to do scaling gymnastics to "fit" the signal to its 1366 x 768 pixel resolution. The less scaling and de-interlacing taking place, the better the image will be.
