I am able to get either a LG, Samsung or Viewsonic LCD. I want a 24" that supports full HD. It will be for use with PS3. What can you recommend?
Don't buy a monitor, buy a HDTV There are loads available out there!! Avforums.co.uk would be your best bet. Wants: 1080P - HDMI - Speakers
A Standard HDTV will likely have input lag as it will have hardware processing designed for TV streaming. If you do go down that route make sure it has a gaming mode where that processing is turned off.
I'm just about to pick up a Samsung 2333HD 1080p for £215. Its 23" but will probably suit your needs.
