Subjective Analysis (continued)
Generally, we follow up our application analysis with a table pitting two LCDs against each other using benchmarks that we derived from VESA's handbook and test patterns from DisplayMate/CheckScreen. All of our monitors are running on an X800 Pro AGP over a DVI connector unless denoted otherwise. Monitors that don't have DVI connectors are compared using a D-sub connector instead. We have simplified our table a little bit so that we can fit all of our data on the same page, but our Notes From the Lab section flags any behavior that we would typically note on the table. The table ranks each benchmark on a scale of 1 to 5, 5 being the best rating and 1, the least desirable.Here is generally how we rate a category:
5 - Outstanding; we have not seen anything to date that could rival our impression of this monitor's performance.
4 - Good, but room for improvement. There are units on the market that perform better.
3: Average; this monitor performs well enough to maintain the status quo, but does not excel.
2: Improvement needed; this monitor performs poorly in performance of this category.
1: Unacceptable; this product does not pass even basic performance requirements.

Notes From the Lab
Above, you can see the Planar PE191M only scored N/A on its screen uniformity test. While the monitor is quite good, the cluster of defective pixels really strained our eyes and we found it fairly difficult to get an accurate reading of the screen uniformity. When we look for screen uniformity errors, we usually look on the corners and sides where light may be seeping through from the backlight around a poorly insulated edge. Since the dead pixels were in the corner, we had trouble when attempting to inspect the corner accurately.You'll notice that our LCDs grab 4.5s pretty much across the board with the exception of the BenQ. Spotting 6-bit LCDs are fairly easy for people who do a lot of graphics work. The image below displays 256 different shades of blue across the top; it represents the 256 hues of blue that are found in an 8-bit sub pixel. No amount of dithering can render this square correctly on a 6-bit LCD.
As expected, the lack of a digital cable on the Samsung 910V hurt it in more ways than one. For most of our other LCDs, we knew that we were getting the correct signal with the test pattern rendered the way in which the LCD manufacturer had intended it to render. After testing a few monitors on a digital connection, we almost immediately recognized small amounts of interference on the 910V, and we did the best that we could to record our observations on the other tests.
We were not real surprised to see the Samsung 193P pull ahead in a lot of the subjective testing. It's a $700 monitor, and it should perform better in many situations. Samsung seems to have a knack for making good panels. However, if we had to pick a second best performer (other than the Dell 2001FP), we were a little surprised to see that the ViewSonic Q190MB and the NuTech L921G had posted generally sound performance numbers. Color was on balance, screen uniformity was there, and glare was fine.

I just (like two hours ago) got my Dell 2005FPW...played an hour of CS:S. Didn't notice any ghosting, blacks were all black, etc. I have my desktop set up stretching across this LCD and my old Sony Trinitron 17" and the color and sharpness on the LCD is markedly better. It actually surprised me; I thought I was giving up color in trade for a wider monitor that's a little easier on the eyes. Nope. It looks great, plays great, and, according to my girlfriend, is lots more stylish.IceWindius - Tuesday, November 30, 2004 - link
Screw LCD, SED is the wave of the future.Until then, i'll stick with my Viewsonic CRT monitor, thank you.

Can anyone go back to the issue that someone asked prior about running non-native resolutions? My biggest deterrent about LCDs was always the fact that if I run my desktop at 1280x1024, I have to run all of my games at that, too. Sorry, but unless I'm buying two video cards a year, that's sometimes hard to do.Can you use other resolutions without getting crappy images?
Yes, at times I have considered selling my 19" and 17" CRT dual monitor setup for one, single 19" LCD. But then I think, nah I love my Philips, and two monitors is cool. Plus I'd hate to have to run all my games at such a high res.

Cat: The lower the refresh rate on the video card, the more sluggish the mouse feels to me. Anything below 75 Hz feels terrible. Setting it up to 100 Hz (assuming your card and display support it) feels extremely fluid. I'm just suggesting possibilities, so YMMV.TCfromNL: From what I can tell, the article doesn't make any such claims about whether you have problems if the GIF appears dithered on your display; it's just presenting a visual aid.

It depends on each peoples eyes, I guess it's not quite as noticable to some. Also not all the 25ms screens are created equal.I have a 25ms LCD, and I don't really notice ghosting, I got it over 2 years ago, though when it cost alot. Though 25ms for an LCD to do continous motion as that enough to generate 40FPS, I also don't really play that many FPS. The new LCD's that are capable of 12ms are amazing that like double the FPS at maximum.
Yeh it would have been nice to test some of the newer LCD panels as well, but to me I don't know why people want it so bright, my LC is around 350:1 range and I already fine that awfully bright, 800:1 just seems so much :S

I'm confused, how can all those 25ms monitors have no noticeable ghosting. I've always known that a black-white measurement does not truly show how much ghosting there will be, but a 5?TCfromNL - Tuesday, November 30, 2004 - link
Okay. Small problem with the 256-shades-of-blue thing, referred to as "the image below".Since it's a GIF, it only contains 256 shades of color, tops. Including all the greys.
I imagine you have a losslessy (or un-)compressed 24-bit copy somewhere. Still, it's not nice to scare your readers by displaying some 20-shades-of-blue thing while saying that if it doesn't display smooth as a baby's skin, which it doesn't, the viewer's monitor is at fault.
Further, nice article. But since these monitors are all 1280x1024 (except for the 20" Dell), I can't help but leave disappointed. I don't like squarish monitors. There's a reason why TV evolved from 4:3 to 16:9. I agree with the cry above: IT DOES NOT MAKE ANY SENSE.

Now to find a good but reasonably priced DVI KVM switch.KristopherKubicki - Tuesday, November 30, 2004 - link
Klah: have they benchmarked any units using that methodology except the example? I checked around and couldnt find any.Kristopher

"klah: I was only aware of Xbitlabs doing so. We feel that the methods for measuring reponse time thus far are OK, but not represent gray to gray response time measurements well. Its something we are working on and we will probably have a better methodology before the next roundup.Kristopher"
Here is Tom's methodology:
