As promised, here are some pics I took of the convergence issues on my new HL61A750. I'm using "just scan" with a PC hooked up to HDMI3/DVI input running at slightly smaller than 1920x1080/60Hz to correct the extra ~2% overscan that remains.
As you can see, it's off by about one pixel. It tends to be better near the bottom of the screen and near the center. In the black and white pattern, on the white half, it is supposed to be a single pixel black line, and on the black half, it is supposed to be a single white line. My camera is exaggerating the effect a little bit, but you get the idea...
I checked my old roommate's older 56" lamp-based DLP (is an 87-series I think from a few years ago... not exactly sure) the other night when I went to his place, and his convergence is near perfect all over the edges. There is a slight hint of the green/red shifting, but it's barely noticeable even when you are 3 inches from the screen.
Is there a setting in the service menu that can adjust this, or should I exchange the TV? I ordered it online from Circuit City. Will they pick up and deliver a new one, or do I need to figure out a way to get the TV into the store? Thanks in advance.
