Dell UltraSharp 2001FP Preview: Gaming LCDs for the Masses

LG.Philips LCD LM201U04
Several months ago, we looked at Hitachi's 16ms response time LCD. This monitor was based off the first commercial 16ms panel, AUO's M170EN05. While this panel is good, it has a few adherent flaws to it. The first flaw is, of course, the 262,000 color limitation. Even though 16M colors can be achieved by dithering the pixels (emulated 24-bit), the evidence was clear when comparing our Samsung 172T and the Hitachi CML174 that Samsung had a dominate edge on color reproduction. Granted, AUO is working to fix that, but the limitations of the TN display mode will probably hinder their progress.Dell's 2001FP is particularly interesting because it uses a 16ms panel that is not manufactured by AUO, the LG.Philips LM201U04. First of all, this panel dramatically increases the pixels on the screen from 1.3M to 1.9M. The second major accomplishment is that LG was able to achieve 16.7M color reproduction as well. Put in simpler terms, this means that each subpixel on the Dell 2001FP can reproduce all 256 shades where as each subpixel on the Hitachi CML174 could only do 64. Ergo the Dell 2001FP reproduces 24-bit color, while the Hitachi CML174 does 18-bit.
The pie gets sweeter the deeper you dig. As we mentioned earlier, the AUO 16ms panel uses a tweaked version of the TN display mode. While this worked great to keep the electric modulation down (that's how it achieves 16ms response times), it does not provide the best characteristics for viewing angle. Due to the orientation of the liquid crystals in the substrate, the IPS mode can tweak a few additional degrees out of the panel. On smaller 15" and 17" panels, this is not completely necessary, but once you start getting up into the 20”+ range, off angle viewing occurs more frequently.

Above is a rough illustration of how the IPS, VA and TN display modes stack up against each other. Special thanks to our friends at LG.Philips for providing the graphics.

to those of you who have the 2001fp, are you happy with the lcd?Singletary - Monday, December 15, 2003 - link
You said: ". . . we ran ColorVision's Spyder and OptiCal software. Not only does this calibrate accurately the monitor on the DVI and analog interface . . . ."Because I can't afford this software, but have this monitor, would your friends allow you to share the calibration file for this monitor?
Thanks!

I just got one. Did you try connecting it to a HDTV cable box? I am interesting in using it as a HDTV and PC monitor at the same time!randolo - Wednesday, December 10, 2003 - link
I just bought and set up two of the 2001FP's. Interestingly, one of them displays at 1600x1200 via analog just fine (no streakiness or blur), while the other is really streaky at 1600x1200, and less streaky (but still annoyingly unfocused) at 1280x1024. Gonna do some reorientation and box-swapping to try and isolate the source of the discrepancy between the two...MONSTERUS - Sunday, December 7, 2003 - link
Hi there! No offence,but there were several parts of review that I didn't like.Most important part:"By popular request".
*The Matrix Reloaded and The Matrix — As with our previous benchmarks, these are not spectacular movies to test colors subjectively*-
Than how come you tested them and not something more colorfull? Matrix movies are all in dark tones, so they will probably look good on almost any LCD monitor.
*both movies were quite acceptable on the 2001FP*-when they say something like that I begin to suspect that movies on this monitor are just "quite acceptible",hope you know what I mean,lets say 3 out of 5 - that's what is "acceptible"means for me :-)
Other concern is that while testing games seems like you only used on game rich in color depth -
Halo,and that was gosting.
Saying "For probably 2/3 of the games we play, pixel blur is not noticeable" makes me wander what kind of games you played more.
Didn't really understand about bluring in Halo,as you said camera captured some blur,but how about your feeling? Did it disturb the gameplay?How often blurin accured?All the time,or just in some scenes?
Lots of people still wander how UT2003 goes on this monitor,because lots of developers are going to use this 3D engine for their future games.
Another concern-there was no clear saying how good watching of DVDs is on this monitor from different angles. Was there big lack on colors and tones from viewing from angle?
Hope to see some answears soon,thank you!

"Halo — We had some mixed feelings while playing Halo. Granted, we spend a lot of time playing Halo on DLP screens via component input (PS2 of course)."dude, its called an XBOX ;P

It's not fair to compare a 1280x1024 monitor to a 1600x1200 one. That aside, my old Radeon 8500 drives the samsung 213T at native DVI output flawlessly. I'd never go back to my CRT. The geometry is perfect, the color is stable and matches my print output perfectly, the gray scale levels are stable and accurate, the resolution is razor sharp edge to edge, and its easy on the eyes. It helps me spot flaws in my images that I never noticed on my CRT. Only drawback is that you can't view it from the sides, you have to have your eyes centered to the screen.henmaster - Friday, November 21, 2003 - link
Actually an 1600x1200 native LCD can also run 800x600 without interpolation, since it is a whole number multiple. So you dont need that great of a computer to run games full screen, without interpolation, on a 1600x1200 native LCD, as you can always bump the resolution down to 800x600.tygrus - Thursday, November 20, 2003 - link
The bulge near the end of the video cable is not an insulator and not a magnet. It is a Ferrite core (two halves) - it forms an inductor circuit with the cable running through it to filter spikes and filter some interference.Analog RGB signals are designed for CRT monitors. Remember that CRT's use electron guns emitting beams of electrons and electro-magnets to scan across a horizontal line hitting phosphorous dots. The signal then goes low (low electron gun emissions) while moving to the start of the next line (typically on the left). This means that any interference or poor signal quality (eg. slow slew rate) affects horizontal pixels. A slow slew rate will cause a smearing of the image horizontally. Poor signal termination (eg. Mismatch of impedance, earthing) can cause ghosting. Poor colour accuracy and interference can also be caused by cross-talk when signal wires are not properly shielded.
I've just done this quickly so let me know if you want more information.

PS. I'm not saying that this article is bad, the following is a comment/warning about articles/reviews in general in print/internet. I get frustrated with reviews that leave information out, make assumptions based on incomplete information or don't investigate/research.

The article does a good job of convering the new LCD. It does a bad job explaining the CONS of a LCD with a native resolution of 1600x1200.As with any LCD if you dont run your application at its "Native Resolution" it looks bad....just plain bad. Most people buying them dont understand this..and then think LCD's dont look good.
To run a new game like Halo on this LCD at its native resolution of 1600x1200, you would need a monster computer....like a P4 3.4EE to get any kind of playable FPS.
Sure it has that zoom out feature to avoid the problems of not using the native resolution...but then why have a 20inch LCD? It would be nice if they made a 20 inch LCD with great response times that came in different native resolutions.
I bought my 19inch because I did not have a system that could run a new game at 1600x1200 at good speed. 1280x1024 was my target, even then some games with my P4 2.4C and 9700Pro need to have AA turned off to get good FPS.
