Man, you gotta tinker with the settings I guess. You did not say what it was or was not doing, so I’ll have to be general.
I was lucky with my TV. A friend was not so lucky either. Here is what we did.

First, Hit the Nvidia site and get the latest video Driver 196.212. Actually, I think Windows update is pushing it out now too.
Second, get into the nvidia console and set up the HDMI out to 720P (my fav for on line content and surfing) or 1080p or i.

Now, the rest is up to the TV settings. Those settings can be adjustable for every input on the TV or apply overall. Every TV is different too and labels the views differently. You Need to turn off Overscan if possible..that oversizes the picture beyond the frame or viewable area of the screen. No cinema, or stretch or anything of the sort. You want Normal setting if available.

Flip through the Settings on the output format or view until you get the best picture you can. Older HDTV’s are funky. You may even end up with a flawless video picture, but the desktop icons may be all fuzzy. If you end up there, then changing the DPI settings on the revo may finish ya up.

I’m having a bitch of a time getting my new 3610 to size correctly on my 50″ Vizio. Any other desktop/workstation sizes appropriately but the 3610 (even if downloading all aforementioned drivers).

What’s the trick?
