Avoid buying a TV as a monitor. The savings does not cover your aggravation.
I bought a couple TVs on a Best Buy sale last year. They were indeed inexpensive, and the picture quality isn't bad - MVA panels aren't as good as IPS, but tolerable. They did need color calibration.
But they're fussy about HDMI inputs. I think they expect modern encryption, when encryption is supposed to be optional. In practice, they wouldn't accept direct input from my somewhat-older graphics cards. I had to get DisplayPort -> HDMI active adapters to make the TVs happy.
And as TVs, they don't do power saving properly - they don't wake up in the morning, when the computer signal comes back. Instead, the TVs turn off after a few minutes, and have to be turned on for each computer session. Their menus are extensive, but don't cover modifying the power saving modes.
Do yourself a favor - pay the extra price for real monitors.
