How to test LCD monitors?

I will be buying a second hand monitor, a Benq LED Benq 24 V2420H FullHD.

What methods can I use to test that the monitor is OK. I mean like dead pixels etc.?


Solution 1:

Best way I can think of is show a fullscreen completely white image. Try to get the contrast on the monitor up a bit, then the dead pixels should stick out like a sore thumb.
