As I understand it, and I'm not an electronics person so I am open to correction....... The refresh rate on an LCD doesn't as such exist.

An lcd screen, (or rather the pixels, (lcd thingys)) operates in an on or off mode and stays that way until it's told otherwise although in on mode it can have different strengths of brightnes and colour.The whole screen is lit by a backlight which may technically have a refresh, (flicker) rate but its way too fast to see or notice.
Anyhow as I was saying yes 60hz is the go

*for the electronics people please excuse the non-technical descriptions, it's the best I can do.

Might I suggest keeping your computer / video card they way it is and buy an LG LCD, the are cheap, reliable have quite a reasonable picture quality.

I'd concur there. Check your local crime, I mean Cash Converters.
I noticed my local the other week had a bunch of refurbished 19" Viewsonic LCD's going for about $150.

Mostly you will find the new LCD's to be very good.
They all use 1 of 2 screens.
There are only 2 factories in the world that make the damned things anyway.

At least that was the case a couple of years ago.

So the only real difference is in most peoples mind.
The advertisers convince them, theirs are the best ones.

There is some thing about the "greyscale" refresh of LCD's that can let them down. And in the early cheaper models "true black" was a complete furphy.
But, that is pretty much over now as well.

Sorry, Garry. But, I reckon your major problem is Vista.

Maybe you mean the contrast ratio?

In general 500-600:1 contrast ratio in normal room lighting condition is considered adequate, (by me it is).

Saying that I believe the newer LCD's have ratios up to 1000-2000:1

I don't quite understand it myself.

It seems to be similar to the colour refresh rate of the pixels on screen, but, it's something to do with the transition of greys on the screen.

(I'm a steamship engineer, spooky white mans magic inside electrickery things.)

Having said that, the newer LCD's are leaps and bounds ahead of any CRT, or Plasma. The speed they operate at, and the contrast ratios, (and there is another thing about the actual overall brightness of the screen as well) all combine to make a damned good unit now.
I'd never use anything but LCD now.

Oh, and the "viewing angle" is very important.

Remember the early LCD laptops? EEEooowwwy.

now theres an interesting observation,,,

I am quite happy with my 21" Hitachi CRT,,
I can run it at 1600X1200 at 100hz,,

It would be interesting to have an LCD side by side to compare,,,

The 21" sony's were(still are??) the benchmark against which all screens should be compared.

Atomic magazine Issue 85 (Feb 2008) - The truth about frames,
is an article about frame rates.
Explains a fair bit about CRT / LCD / FPS etc.

Is Atomic still up and running? Wow.
I'd better go down the newsagent's one of these days.

its not a bad tech forum,, if you can deal with 14 year olds,,,,

any comments re above ? as I was about to post a new thread before I read this one.

I was seriously thinking of obtaining a 2nd hand Sony (Dell, et al) 21" CRT screen instead of a new LCD screen.
