Is refresh rate important in LCDs?

I was looking at that monitor at CompUSA last night and it was set at 60hz at 168x1050 and I didn't see any flickering. I don't think its as important as it is on CRT's.

It is impossible to see flickering in LCDs because all the pixels are lit continuously.

I believe most LCD's have a refresh rate of 60MHz. Once you have LCD, you'll never go back.

60Hz, not MHz.

for lcds, the refresh rate is how often a pixel receives an update. this will only really matter in games as you will be limited to seeing 60fps no matter how fast your computer renders the scene.

If you have V-sync enabled the refresh rate of the LCD will be the highest framerate you'll see in games, however if you disable this feature you may notice more tearing in the graphics.

However a steady 60fps is plenty fast & 75fps is even better.

The highest most LCD's go is 60hz at native res.

The highest I've ever seen one is 75hz and thats only at 1280x1024.
For the most part, it's gonna be 60hz so it's not so much that it matters (cause it doesn't) but that you don't really get a choice.

I have LCDs at home and work, and I have no problem going back to my 22" AG CRT.

that's not surprising considering the backlight is fluorescent

That can be a problem for me. I remember being in school, and those fluorescent lights drove me insane. It's like sitting under a strobe light.

It's strange to say this but they put me in a daze. Even at work nowadays, I experience the same thing. If I sit under those lights for a few hours I just zone out. I'm ok under incandescent lights and sunlight near a window is the best.

On my CRT monitor, anything under 85 hz drives me up the wall, and 60 hz will make me feel ill after a few hours. Also, the LED taillights on some of the newer cars look really bad to me.

Apparently almost every 75hz LCD out there simply discards every fifth frame when operating at that refresh rate, so they don't really work at 75hz at all. However, the 75hz setting is often still preferable to 60hz due to how vsync works. The tearing or heavier framerate drops in a game are usually much more noticeable than the skipped frame.

I think it's all in your head. LCD backlights are cold cathode fluorescent lights. They don't flicker the way old fluorescent lights did.

How is it all in my head when I can see it without a problem? Not all of them seem to do it, either. But on some of them it's completely obvious.

Are you able to see the LED taillights flickering on new cars, or do you think that's in my head, too?

Ok, which model. I don't remember seeing any new working LCD monitor that flickers.

Didn't I hear something about 120hz refresh rate monitors awhile back that supposably had better picture quality? I forget.

I would look for a 20" monitor instead. 22" screens are simply stretched out 20" screens. Same resolution, bigger gap inbetween pixels. 0.282 vs 0.258 dot pitch. You're trading size for image quality.

It wouldn't be a new model, there were some at my old job a few years ago that did this. Once in a while I'll see one at work like this, but it's probably not new.

I figure that they're getting better, that's why I posted another thread on this forum asking which one I should get.

Those aren't actually 120hz. They insert a black frame between every two real frames, which apparently improves the response time. I don't know when they are supposed to come out though.

BenQ has this technology in some of their newer displays right now. Not sure about any other manufacturers, but I know BenQ has already implemented that technology (more info available on their site).

You need to get your workplace to switch from magnetic to electronic ballasts for their fluorescent lights. Modern ballasts eliminate the fluorescent strobe problem. Doing so will save them money in electrical costs in the long run anyway.
