The following summarises the HZ30W's performance in video applications:
Massive 30" screen size and widescreen aspect ratio make it great for watching movies, and bigger than many LCD TV's
Massive 2560 x 1600 resolution support for high definition content (even supporting 1600p content which is apparently the future of HD!)
The resolution can be a problem however since any SD content (and even 1080p for that matter) content needs to be scaled up, and the resolution means any imperfections and pixelation are accentuated even further. Not a good screen for watching anything from close up
Wide viewing angles thanks to the S-IPS panel, good for several viewers watching at once
Decent black depth from this panel, especially once calibrated. This is usually a weak point of S-IPS, but in the case of the HZ30W, black point is good. This ensures detail in darker scenes is not lost
Panel uniformity is good, with only a slight leakage along the bottom left hand edge. Not something you notice in movie viewing, even with black borders from DVD's
HDCP support over the dual-link DVI allowing encrypted Blu-Ray and HD-DVD content to be played back properly
Lack of any additional interface options is a shame. There's no HDMI, DisplayPort or Component here for connecting external devices
Noise is noticeable due to the screen size and resolution, and particularly apparent with low definition content. You need to sit a fair distance away to get away from this. HD content still looks very nice though, even from up close
