Use a screen saver set to activate after a few minutes. This means five or less.
Is every system and the graphics card compatible with the TV? If it isn't, you won't be happy.
If you really want to know performance, go to a store.
Look in the hardware sections of different Linux/GNU and *BSD forums to see what the people posted as problems and performance for both lcd and plasma monitors.
i currently have a sanyo 27" walmart tv. i am about to purchase a 1080p hdtv and a playstation 3. i will be connecting my playstation 3, my pc laptop, and my mac desktop up to this display to use as a monitor, all wired to my surround sound system.
I have done some reading, and i cannot figure out what kind of display to purchase. there are so many fans and arguments of plasma vs lcd that i cannot get a straight answer. This is made even more difficult being that i will be using it for gaming and as a pc monitor. lcd seems more logical for this dual-use, but i hear alot about refresh speeds and the shades of black. on the plasma side, i hear alot about burn-in which hinders use as a pc monitor.
the tv will be getting alot of use as both a monitor ( i do graphic design work in windows and mac,) and as a game system (my kids and I all play games alot.)
So some help would be greatly appreciated. which should i go for? plasma, lcd, projection?
also, i am looking at a budget of no more than about 1500.00 . i don't need something huge, but 32" or bigger is a must. i want something with longevity being that i do not have the money to buy a new tv every year. this is a purchase that i have been saving for.
so yeah, please give me some sound advice or links to studies or tests that will help me in this major purchase. thanks.
