JPG Resolution test pattern on Hit. 57S700

I found a resolution chart jpg on www.imaging-resource.com and I scaled it down to 1620x1080 with a Lanczos filter:

I downloaded it into my camera's memory card, and stuck it into the Hitachi's card reader. I can't take a picture of the image because I only have one card (duh!).


There is a bit of overscan in my set. There is some fairly strong line twitter visible in horizontal lines at about 550 lines.


With vertical lines and the vertical wedge, there is strong detail to about 750 lines, then contrast fades and you can't really count the lines at around 825.


With horizontal lines and the horizontal wedge, some artifacts start to appear at 800 lines, but you can make out detail to a bit over 1000 lines.


FYI the test pattern is exactly one pixel wide at very close to 1080 lines.


So, is this a good result? I have done manual and electrostatic focusing on my set.


At my 9 ft viewing distance I can barely make out the 800-900 lines horizontal resolution. If I step into the next room at 13 ft, I can just see about 500 lines (~DVD resolution). So I guess 57" is just the right size.
