Author Topic: 19" 8ms LCD Screens (Read 340 times)

Anyone own one of these 8ms LCD's? Able to give an opinion on what the display is like for flightsims? Sold my 21" CRT and need a replacement when in a few weeks.

Cheers

Have a 21 viesonic VP201, and I think its 20 something MS... but I think it looks way better then my last CRT, and AH looks great.

Plus it is light.

There are already a couple 4ms models. The faster the better.

Yes, thanks for that. Was going to look into those also but wasn't sure on the performance gain over pricing and that maybe 8ms should be enough.

Faster isn't always better.

A lot of the faster screens are only 6 bits per pixel, so they can only display approx 260,000 colours. (you need 8 bits per pixel, 16 million colours, for true colour reproduction)

Anandtech have done quite a few 19" lcd tests recently.

VP201 is 16 ms.

There are also some LCD's that has a pretty high res time (20 something), but they use something called overdrive that actually makes them just as good as 8ms panels. I belive some LCD tv's use overdrive instead of very low ms speeds due to better colour rendering.

I think the test i saw was an Eizo or maybe Samsung model but dont trust me on that. google for lcd and overdrive and you will find some.

-edit-

"LCD Overdrive
Another well-known problem even with active-matrix LCDs is the poor response time of their LCD pixels, which can amount to several tens of milliseconds. This is made worse by the fact that small changes in grey-scale actually take longer than black-to-white or white-to-black transitions. The result is a smearing of picture motion, because the pixels cannot keep up with the changing grey-scales caused by moving objects in the image.
To overcome this problem, Philips Research has developed a technique for momentarily 'over-driving' each pixel with a voltage higher than is needed to achieve the required static grey-scale change. Establishing the correct amount of overdrive requires measurement of the response times for all possible grey-scale transitions, but this only needs to be done once for a particular type of LCD and is then built into pixel processing algorithms in the display driver electronics."

http://www.tomshardware.com had a review this week on that very topic

I have the ACER AL1912b, it is a 16 ms responce and was touted by many reviewers on newegg as having good responce and no ghosting. I have to say it works well enough and I do not regret buying it in the least, but it still has a noticeable bending of the wings effect as planes streak across my screen, and plane ID's can be hard to read when moving quickly.

My buddy liked mine so much he bought the new one, the ACER 1914 with 8ms responce. It looks a bit sharper and crisper in FPS games, an excellent all around monitor. But neither compares to a quality CRT.

I have a samsung syncmaster 930b (19", 8ms response). I like the thing quite a bit, although it was a pain in the bellybutton to set up as the colors were all jacked up. I had to do quite a bit of fiddling with RGB, contrast, gamma, and brightness to get it to look right.

In AH, I notice no ghosting of planes. I do notice that enemy icons are somewhat hard to read when they're flying by quickly. However, I'm chalking this up to the fact that I don't run the game at the monitor's native resolution (running that high kills my framerates). The icons thing isn't a dealbreaker, and I imagine it would get better if I had a box that could run the game at full resolution.

Native resolution is a must with tft, if you can't muster the res, use a smaller screen or crt instead.

The 6-bit panel is acceptable on gaming use if it gives you a 4ms response time. Sure there will be dithering but I know I won't be using my gaming box for any kind of professional imaging. I will however use it to play all kinds of games where response times are essential.

Thanks for all the info and opinions. Main use is going to be for photography and FS2004. Are the colours quite screwy if your trying to look at high quality photos?
