It doesn't seem nearly as sharp as it should be.
When connected to the Mac, the aspect ratio is locked at "standard" and I'm unable to change it. Westinghouse tech support claims that when the HDMI is driven by a computer that the ability to toggle aspect is disabled. When connecting other 1080p devices, the VR-3225 switches to full and the screen looks correct.
Am I doing something wrong? Does this thing have to go back?
A common issue when first hooking up a TV to use as a monitor, they are never plug and play. But 99% of the time this issue can be corrected.
And no, it is not normal, overscan should always be disabled in the videocard control panel. You have discovered a bandaid solution, but your problem lies elsewhere. There is a setting mismatch or conflict here, settings in both the graphic driver and TV menu.
You can start by disabling all TV visual enhancement settings, (except
contrast/brightness/backlight) even the sharpness setting should be lowered almost all the way down.
And as mentioned prior, your rez should be always
be set to 1920x1080 @ 60hz. Every once in a while, with certain TV's or hardware, the refresh needs to be set to 59hz (like with my panasonic).
You may want to make these changes one by one, testing along the way. And jot down the default settings in case you have to reverse any of the changes you made.
Hopefully you are in the 99% i mentioned and that your issue is correctable. Don your patience cap and good luck either way.
