I cannot find any positive comments on this low-end TV, Jose. Here's a sample post...
Pros: Decent enough for analog TV signals
Cons: Poor manual Awful PC support Limited PC resolution Sluggish remote Clumsy menu Price feature ratio
As a TV, it works as advertised. The response time on the remote isn't instantaneous, which can get annoying. That's only the tip of the iceberg though.
As a PC monitor, the 20PF5120 stinks. I tested it on a GeForce 7600GS. I
did manage to get dual monitor to work, but the manual was useless. Switching to "PC" mode doesn't work. It just registers no signal, despite being detected under Windows.
I had to switch to DVI mode to even hope to get a signal. Even then, I had to fiddle with the Control Panel to independently configure the display res to something smaller than my other LCD. Contrary to what the manual states, it would not even reach 800x600 at any of the desired refresh rates. Sadly, it was limited to 640x480.
My 21" PC monitor cost $100 less and easily handles 1600x1200. Not this TV/monitor. For a 20" LCD you'd expect higher resolutions. Very low end. One would suspect that much of the cost is due to the TV/HD support. Couldn't be the PC support. Strictly amateur hour.
