Vizio VO37LF 37" 1080p LCD TV

Last week I bought and returned a 37" Toshiba HDTV due to unacceptable lag when gaming. Since that time I've searched the web a lot, but I haven't really found any credible information on the amount of lag found in other models - so I figured I'd just have to spin the wheel again and hope for the best. So I spent the store credit I got for returning the Toshiba on another 37" LCD - this time the Vizio VO37LF. It cost $40 more than the Toshiba ($690 total), but it's 1080p.

And I'm happy to say, despite not having a Game Mode per se, the Vizio is worlds better than the Toshiba for gaming. Rock Band 2 (Wii, 480p over component) lag calibration worked out to 30ms video / 20ms audio (vs 50ms video / 100ms audio on the Toshiba in Game Mode).

I played a couple of songs in DDR Supernova (PS2, 480i over Component) and got a AA on Difficult, beating my old record I got on the 20" CRT! Not a bad first impression.

As far as picture quality goes - upscaled SD is sharp, maybe a little too sharp (text looks great and is much more legible than the 20" tube; some graphics look blocky, though). OTA HD looks pretty nice too, maybe not quite as nice as the Toshiba, but I haven't played around with the settings much (and the quality of the feed has a big impact, I'm sure).

Things I have not yet tried: Watching DVDs (the PS2 can allegedly do this in 480p; if it doesn't I might have to grab an upscaling HDMI player). Connecting a computer (it can supposedly do 1080p over VGA).

Update: I watched a few minutes of Apollo 13 on the new TV. The PS2 does indeed play DVDs in progressive-scan, and it looks great. Very detailed - you can read the labels on the spacecraft buttons and probably count the actors' eyelashes in close-up shots. From a normal viewing distance on the couch, it looked almost indistinguishable in quality from OTA HD. I have no need for an upconverting DVD player - from a 480p signal over component, the TV does a good enough job of it on its own.

Update 2: I plugged a MythTV box into the VO37L via the VGA port. It works beautifully at 1920x1080. My Tux Racer framerate at this resolution is poor (GeForce 6150 integrated video isn't up to HD gaming), but HD content in MythTV look great and plays back smoothly at a little over 50% CPU utilization (Athlon 64 3200+). Note: You can perform an auto-adjust with the remote control (top item in the on-screen menu) to get the TV to re-sync to the analog video signal. I had to do this while displaying a test pattern to get the picture lined up exactly with the edges of the screen.

Update 3: The TV resolves pixel-perfect 1920x1080 from my laptop via both VGA and HDMI inputs. (I had to play with my video driver's underscan setting to get it to do this over HDMI, but this is the computer's fault, not the TV's.)

Also, I've noticed a few defects with the display:
  • Two dead pixels (dark, not bright, so they're not covered by Vizio's "no bright pixels" promise). These are, however, not noticeable from a normal viewing distance (and not noticeable at all unless there's a bright background).
  • A bright spot at the top of the screen, just left of center. It's only visible when the screen is black, and looks like a reflection - except it's there even when the room lights are off.
  • Brightness falls off a bit on the extreme left and right sides of the display. Not noticeable while watching TV, but a slight distraction while using the TV as a computer monitor.

  • Still happy with your Vizio? I'm considering the Toshiba and the Vizio from Costco...

  • Yeah, I'm still happy with the Vizio, and would definitely recommend it over the Toshiba if you're into rhythm games at all.
