Brightness can't catch up! Please help!

Jul 15, 2009 4:04PM PDT

I have a 42" Vizio VO420E HDTV that I've been desperately trying to watch my old DVD collection on.

First I tried DVD upconvert with my Xbox 360 via VGA cable....terrible.

Second, I ordered a few HDMI cables and tried those with the 360 and SD DVD....terrible.

Finally, I've tried 2 different HD Upconvert DVD Players via HDMI and the standard DVD's still looked like crap. What's more, I've now noticed a new problem:

When the movie(s) switches from a very dark scene to a very bright scene, the picture takes a about 3-5 seconds before the brightness of the new scene can catch up! I went back and retested all the methods and it happened for every single one!

I tried: different DVD players, different cables and different DVD's. Same thing every time. However, this problem doesn't happen with 360 videogames, nor regular TV.

A buddy of mine has an old Memorex DVD upconvert and I don't remember this ever happening to him on his Vizio. Is this normal? Is it just because the TV is too advanced and the SD DVD's can't catch up? Or is there something wrong with my TV?

Please help!

The set is using dynamic contrast. Now go try that same content and players on a plasma display.

For the DVD part, make sure you set the player setting to 1080i, 1080p (which ever one your tv is) and list the brand of the others you have tried. Most no name brands will suck, most newish brand name players on that sized tv DVDs should look somewhat good, every few will do a real good job.
And make sure your tv is not set on Vivid mode.

turn off all video processing that you can

Try to go into your display setup menu and turn all the video processing enhancers to off.
