I bought a Vizio VX37L at Costco the other day. The first one had a defective screen and the picture was grainy and looked awful overall. The second one has a better picture but the colors look somewhat washed out. They are not vibrant at all. The display models (I went to two Costco's) looked pale compared to those around it. I had noticed this before I bought it, but guessed that they just didn't have everything turned up on the display unit, actually they did, that's just how the picture looks. I'm dissappointed in this, especially because the L37, it's less featured and lower contrast brother, got such awesome reviews.
The tuner is nice, I picked up 136 hd channels and 80 regular channels via my basic cable connection. The regular tv channels look extremeley pale and greyish. Plus they are all fuzzy, not very good clarity. The hd channels are hit or miss. So far, Starz! is the only channel with a really nice picture, though it's still a bit faded out looking. To be honest, with the exception of the one channel, everything looked better on my old RCA 36" crt tv. DVD's are less than inpressive, currently I'm using the components and feeding it a 480p signal. These looked much better on my old tv too, and that was fed through a 480i signal over component. There is a lack of detail that was there before and the colors are all lifeless and dull.
I'm going to return it in a few weeks, after I decide what else to get.
