LCD vs CRT, refresh rates

Ive been looking at a couple of LCD displays for quite some time. What I noticed was that a 15 inch LCD display has a recommended resolution of 1024x768 @ 60-75hz. I have my 17in monitor running at 1024x768 @ 85hz because at 60hz my eyes cant jst take it.

My question: Is LCD 1024x768 @ 60hz equal to CRT 1024x768 @ 60hz?? Or In other words, will the LCD @ 60hz look as good as a CRT @ 85hz???

It is very different. You can look at an LCD at 75hz for days without having eye strain.

Problems with LCDs:
-the picture doesn`t look so natural like on CRT monitors
-larger pixels
-small refresh rate
-the angle at which you can look at the monitor to see the picture
-price

I think you already know the positive sides of LCDs. The only reason for me not to buy an LCD is because hardcore Quake-ing is crappy on it(becasue of the smaller refresh rate, which isn`t noticeable in normal games).

From what I understand, you shouldn't get eyestrain as easily with an LCD, since they don't actually have a refresh rate (the pixels are constantly lit if you didn't know). I can't really recommend which is better however, since I've never owned an LCD monitor.

LCD's have only one thing I dislike. Unless they're used with a DVI graphics card, you get the diagonal ripple. It looks terrible.

Invest in a radeon first...

I don't know about a diagnol ripple (could you explain that Kaitan??), but I will never go back to CRT. I've had a 15" LCD for the last 4-5 months and absolutely love the damn thing.

If you're using an LCD screen from the ordinary analogue out on a graphics card, most LCD screens appear to have faint diagonal lines coursing from top-left to bottom right. Certainly the ones at work all have that... and they're reportedly top-of-the-range flatscreens.

Funny, never seen that, and I use the analog out...

From what I've experienced, I've seen enough problems with pixel jitter and other nasties using an LCD from an analog source. I wouldn't consider using an LCD unless it was driven from a digital source. I wouldn't consider using an LCD until they get the dark performance sorted. My system is used by people who do a lot of photographic work, and an LCD just doesn't cut it against a CRT.

I can definitely agree with the dark issues, wish to hell black was 99% black and not 80%... but jitter, etc?? Maybe I got lucky with my NEC and Radeon/GF4 cards I've used, because I just don't see any distortions...

I don't know why this is, but I've seen numerous LCDs and LCD Projectors that have suffered from pixel jitter. It also seems that some patterns on the display give the system a harder time than others.

I don't know why the jitter occurs - it's certainly a sampling rate issue somewhere. On the other hand, if you have a digital output on your GFX card and a digital input on your LCD, you won't suffer the pixel jitter problem!

If you are seriously considering an LCD, there is quite a bit of first hand experience in this thread.
