The HDMI display (set to 720p) is not in sync across the entire screen. The bottom 1/4 or so is out of phase with the rest of the image. I can't tell if it's lagging or leading, but it's very distracting, particularly in action sequences. Is there a way to fix this?

This could be a problem with the tv's memory. Try resetting the TV. Unplug the unit for a few seconds (10-60). Then restore the TV to the factory default settings. Viewsonic has changed it's menus at intervals so you may have to check your manual. It may be Menu > Setup > Memory Recall or Menu > Options > Restore Default (or something slightly different). From there, click enter, use the right or left arrow to select YES, hit enter. Leave the menu system (Menu twice). Then hit Menu > Channels and rescan all channels.
An alternative cause of the problem may be a weak signal - check that your antenna is pointing right at the station and is the correct type to get the signal at the distance you are from the station. (Usually a weak signal would also have the audio breaking up but weird things can happen.)
I hope this helps.

(who recently had a channel pair that started out with flickering signal issues and then had one channel lose video and the other audio. The memory reset and rescan resolved the problem.)

I had the same issue and the inverter board fixed it, you can find it at shopjimmy.com.
