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.

coming out of the gate late (compared to the dell 2405) and also charging more for the same thing is hardly a good way to try to compete...this just guarantees that dell will continue to the winner in this round.
i mean the average consumer will see 2 of the same monitors with a $250+ price difference, hardly a decision that will take more then a few seconds to 'analyze'.
HP needs hooked on phonics...going the way of gateway, cept gateway at least mattered at one point...

It is retarded when they crack open a monitor to show the insides. There's NO REASON to do it if we already know what kind of screen it has. It can't be upgraded. It can't be modified. It's just a hunk of silicon we've all seen before. Big deal.Deinonych - Friday, July 8, 2005 - link
Dell's high-end monitor line is branded UltraSharp, not UltraSync. You may wish to change these references in the article. :)KristopherKubicki - Friday, July 8, 2005 - link
BoboSama: Unfortunately I don't think any LCD could really stand up to a CRT as far as response time (since there isn't any on a CRT) or image quality (it's much higher on a CRT).Also keep in mind that a 21" Trinitron has about the same viewable area of a 19" or 20" LCD.
What do you use your displays for primary? If it isn't gaming or photographic work then the LCDs reviewed today will probably be just fine.

I don't get the comment in the article "but it's only been a few weeks since it broke the magic $1,000 barrier."I can't see it for under $1000 anywhere...

Is there anyway to benchmark this LCD against a 21" Trinitron Flat Tube CRT for image quality and other specifications? I currently have dual 21" CRT's for development and I would like to know if two of these monitors would be a suitable replacement.flatblastard - Friday, July 8, 2005 - link
#10 We should be asking you that question, since you have both of them on-hand.flatblastard - Friday, July 8, 2005 - link
....and maybe then we'll finally have a screen technology worthy of replacing direct-view CRTs.Quanticles - Friday, July 8, 2005 - link
If you want headshots in counter-strike there's only one way to go... and those usually weight 60 lbs...two more years and maybe..

I have the Dell 2405 and the HP 2335 on hand. Has Anandtech reviwed the Dell? Which one is superior for gaming and color accuracy?Any thoughts?
