Laptop LCD Roundup: Road Warriors Deserve Better

Brightness and Contrast Ratio
For these tests, we depend on the hardware colorimeter and software to help calibrate and measure the results from the displays. As previously stated, we use a Monaco Optix XR (DTP-94) colorimeter and Monaco Optix XR Pro software. On desktop displays we normally do some basic calibration to try and select an optimal brightness level, and we also look at the maximum and minimum brightness available. At least for the laptops we've seen so far, we really see no purpose in reducing the maximum brightness level except when running off of batteries. The ASUS G2P might be bright enough that that's an option, but the other three laptops already feel rather dim to begin with.
Objective testing confirms our impression that the ASUS G2P is easily the brightest display out of these laptops. The black levels may not be as dark as some people would like, but the net result is that you get a nice bright picture with a good contrast ratio. The ASUS A8Js goes the other route, offering mediocre whites and the worst blacks out of any of the laptops. This results in a very low 231:1 contrast ratio. The Dell and MSI laptops are similar in that both have dark blacks but only moderate whites. While this ends up giving the Dell XPS M1710 the highest contrast ratio, we definitely prefer the overall experience of using the G2P display.

I am not all that opposed to lower resolution screens when it comes to a laptop. Laptop video chipsets are often times slow enough as it is, and when my 7200 G0 64MB (256MB TC) is attempted to be used for gaming, 1280x800 gives a much better experience then some 1980x1600 breatly resolution.MrPickins - Tuesday, May 22, 2007 - link
4 screens, and not a single one a 15" model? How does that constitute a "roundup"?This article needs far more models tested to be worthwhile.

It's a roundup of what we have right now. I have some 15" laptops coming for review, and if this wasn't made clear we will be performing these same tests on all future laptop reviews. This was just a way to jump start things before the laptops we currently have are sent back.MrPickins - Tuesday, May 22, 2007 - link
Don't get me wrong, I like the article's intent, and the tests run. I just feel it would have been better to wait and give a large comparison all at one time, rather than piecemeal.EarthsDM - Tuesday, May 22, 2007 - link
Great article. If you guys wouldn't mind, could you do these tests to the MacBook and MacBook Pro? In light of this new lawsuit (see below) I'd like to know how good my MacBook Pro's display is, i.e. 6-bit or 8-bit. Thanks!http://arstechnica.com/journals/apple.ars/2007/05/...">http://arstechnica.com/journals/apple.a...it-over-...

Great job on the article. I had no idea the G2P's display was so demonstrably superior to the competition. I'd be interested to see these tests performed with two more variables:1) How do screen options within a single laptop model score? For example, if you get a Dell Inspiron with the default screen vs the upsell for the "Ultrasharp" model. Such a comparison could also give you two systems that are alike in every other way so you could discern the impact of the "better" screen on battery life
2) I always hear about how Macs are better for multimedia applications. Does the colorimeter and software work with Macs, as well? If so, I'd be interested to see whether their color accuracy is truly better than those of competing laptops.

I'd assume you could test the colorimeter on a Mac running Windows, shouldn't affect the screen quality.bldckstark - Wednesday, May 23, 2007 - link
Apparently recent testing on the Mac's have shown that the display performs better under Windows than OSx. This is one of the reasons they are being sued right now for claiming better visual representation than "regular" notebooks, when they appear to be the same as all the rest.I don't know anyone who has a Macbook, Pro or not so I have not seen this.
I have been on the edge of buying a Macbook for some time, but when push came to shove, I bought a Lenovo. It is hard to find someone (now I am sure millions will reply since I said this) that thinks the other manufacturers are even in the same league as IBM was. So far Lenovo has been doing a good job of keeping the Thinkpad up to snuff, so I couldn't reasonably spend my money on something I had never seen before and had no consistency in manufacturing from one model to the other. Besides, there is that keyboard 8^)

This article was TREMENDOUSLY helpful. As most laptops are bought online it is impossible to be able to determine what an LCD looks like, short of going to a company's kiosk.Please continue to do reviews like this.

Agreed. It's about time someone included one of the most important part of a laptop in the review process. I also appreciated the comparison to desktop LCDs. I have been sticking with my CRT, in part, because of the stark difference in viewing quality between my laptop and desktop PCs.
