HP L2335: Low Response Time and High Resolution LCD

Quantitative Analysis
For the duration of this review, we connected the HP L2335 to a Radeon X800 Pro with factory default settings on the DVI connections unless stated otherwise. Brightness has been set to maximum as well.Luminance
Brightness ranked as one of our most important display qualities. On a display like the L2335, a dim image can make for a very poor viewing experience, since the resolution is so high. Fortunately, large displays are usually compensated for this with the addition of larger and brighter backlights. Too much compensation will result in an overly bright image, to which black levels and contrast ratios will suffer. Below, you can see a comparison of the brightness for each of our LCD monitors.
Our Contrast Ratio
We will use the same observation from the 19" LCD Roundup several months ago. Using PreCal and our ColorVision Spyder, we will measure the luminance of a pure white image and a pure black image on the LCD monitor. The observed contrast ratio is simply the highest recorded luminance divided by the lowest. All measurements are in candela per meter squared; larger contrast ratios are more desirable.| Observed Contrast Ratio | |||
| Highest Recorded (white image) | Lowest Recorded (black image) | Observed Contrast Ratio | |
| Apple Cinema 20" | 247.4 | 2.4 | 103.1 |
| BenQ FP931 | 256.4 | 3.6 | 71.2 |
| Dell 1905FP | 234.6 | 2.6 | 90.2 |
| Dell 2005FPW | 280.4 | 2.6 | 107.8 |
| HP L2335 | 280.5 | 2.6 | 107.8 |
| NuTech L921G | 278.2 | 2.6 | 107.0 |
| Planar PE191M | 234.0 | 3.0 | 78.0 |
| Samsung 193P | 230.4 | 2.2 | 104.7 |
| Samsung 910V | 219.8 | 2.6 | 84.5 |
| Sony SDM S94 | 233.8 | 3.0 | 77.9 |
| ViewSonic Q190MB | 261.8 | 2.6 | 100.7 |
Again, there is no surprise here where the HP performed the same as the Apple Cinema Display and the Dell 2005FPW. Since all three use LG.Philips LCD panels within the same generation, we had expected this. Again, note that the accuracy of our ColorVision Spyder is within 0.2 cd/m2 only, and this plagues the accuracy of our results. Our numbers should give you a good estimation of where each display falls in line with another, but it is far from an absolute authority.

Wish I could afford it!slayer01 - Friday, July 8, 2005 - link
I work for LG and repair LCD monitors all day, and LG does make some good panels and monitors. But LG has screwed Dell for the last few years and Dell is probably going to drop them from all the Dell models. LG and Dell have been battling the "mura issue" as of late.bersl2 - Friday, July 8, 2005 - link
Now, take *exactly* this display and scale it down to 19"-20" and $750-$800, and maybe then we'll talk.racolvin - Friday, July 8, 2005 - link
I'm obviously missing something somewhere. Can someone give me a link that would explain the diff between SIPS and PVA? I have the Dell 2405FPW and so far its been awesome - and yes, I game with it :) There was obviously some preference for a SIPS panel that I just don't understand, and since I had considered the HP before I bought the Dell, I'd like to understand what I missed the first time around :)Questar - Friday, July 8, 2005 - link
"...the drab silver bezel reminds us of a circa 1998 HP desktop."Or maybe a 2005 model? All HP corporate systems have a silver bezel.

What? No solitare benchmark?Gatak - Friday, July 8, 2005 - link
I'd like to see colour accuracy with the tested TFT monitors. As a graphics artist and photographer this is very important. More so than response times.Capt Caveman - Friday, July 8, 2005 - link
I've had this monitor for over a year. Back then it cost $1400 and was a steal compared to the Sony 23" and Samsung 24" LCDs both over $2000.I've always enjoyed playing games on it and glad to see it get some props. I was jealous of the Dell 24" LCD for it's price and supposedly 12ms response time but I guess that's just marketing spin and the L2335 is actually more responsive. Nice Review

awesome. so does it take the gaming crown?
