Most newer-model mainstream TVs and monitors all have 60Hz HDMI inputs while the output speed after processing is what is noted on the box; primarily 120Hz or 240Hz on TVs these days. You would get similar performance whichever you went with. I like the LED monitors or TVs better. It's all a matter of personal preference and how you want to arrange the furniture. I would think you'd go with something called a TV because it has a larger screen. While the smaller monitor, in my opinion, tends to give the whole thing a more personal feel.
The picture definitely differs from brand to brand. Go to the local electronics shops and check out the pictures. Try out the controls too. I've noticed a lot of shops will dull down the pictures of those units they aren't pushing while optimizing the screens of those they are pushing at a particular point in time. Playing with the settings allows you to optimize the picture.
I should point out that this is only for gaming. I have a 55" HDTV already for watching tv. I just been using a 21" Trinitron monitor for 10 years, and while it still works great and I do like them, the contrast certainly suffers.
sounds like I need to go with an LED.
I had read about the different kinds, the Twisted Nematics (TN), IPS, and MVA technologies.
While they are cheaper, I do not want a TN monitor due to their poor color. Is there a way to see which technology each monitor is made on?
I am thinking about spending $300 to $500.
Seems like Viewsonic and Asus make the nice monitors and for a HDTV id go Samsung or Sony.
