Test Setup

We have covered this information in our desktop LCD reviews, but for those of you unfamiliar with some of the terminology used when discussing displays/LCDs we refer back to our Gateway FPD2485W review. The various specifications have become somewhat meaningless on the desktop, as the difference between higher contrast levels and higher quality isn't immediately apparent, for example. On notebooks, things are further exacerbated by the fact that most of the LCD panels don't list any specifications beyond the size and resolution. In some ways, this is the reverse of what we see on the desktop; we would almost go so far as to say that the manufacturers are aware of the poor quality of their laptop LCDs and they don't want to draw attention to this fact by listing specifications.

We couldn't dig up much information beyond the size and resolution, but we will provide actual measurements of some of the specifications later in this article. Here's a quick overview of the displays on the four laptops we're looking at today, all of which have been previously reviewed here at AnandTech. Hopefully, notebook manufacturers will begin to include more detail in their specifications in the near future.

Laptop LCD Specifications
Panel Size Resolution Panel Vendor Penel Model
ASUS A8Js 14.1" 1440x900 CMC CMO 1416
ASUS G2P 17.0" 1440x900 AU Optronics AUO 4087
Dell XPS M1710 17.0" 1920x1200 Seiko Epson SEC 3155
MSI S271 12.0" 1280x800 Unknown Unknown

Update: One of our readers suggested we try using a utility called Advanced System Information Tool (ASTRA32) to determine which LCD panels were actually being used in our test laptops. While we can't guarantee that the information is 100% accurate, it's at least something some of you will find useful. (Note for example that we were unable to get any details of the MSI S271 panel so far, but we will update the table if we can find updated drivers that will work with ASTRA32.) There is a very good chance that some notebook manufacturers will source LCD panels from more than one location, so for example the Dell XPS M1710 we have for testing may not be (and probably isn't) representative of all such laptops in the area of the LCD panel.

We mentioned in our review of the ASUS G2P that it had one of the best notebook LCDs that we had ever experienced, and our opinion has not changed. The only drawback is its relatively low resolution for a 17" laptop, but we have seen some other laptops advertising "ultra bright" LCDs with 1680x1050 and 1920x1200 resolutions, so those may be comparable to the G2P LCD. We can also say that the 1920x1200 17" laptops that we've encountered to date (the ABS Mayhem Z5 and some brief use of an Alienware notebook) appeared to be very similar to the XPS M1710 display.

Given how rapid desktop LCDs have been improving over the past three or four years, we're actually a bit surprised at the relatively low quality that we find in laptop LCDs. We understand the need to conserve power, particularly when running off of batteries, but the performance of laptops has reached the point now where many people would be more than happy with midrange (or even entry level) processor and graphics performance with a high-quality display, as opposed to extreme performance with a low-quality display. In some ways, the ASUS G2P is a perfect example of this, as its graphics chip is relatively underpowered compared to many of the other similarly priced notebooks. As we mentioned in our review, despite the "Gaming Series" moniker given to the G2P, it serves far better as a moderately powerful laptop with a great display than as something suitable for mobile gaming.

Just like in our desktop LCD reviews, we use a Monaco Optix XR (DTP-94) colorimeter and Monaco Optix XR Pro software for most of our objective measurements. Since the majority of people don't have such hardware/software available, we will also look at the uncalibrated performance of the notebooks.

    You actually need hardware as well as software for color calibration - IIRC the Monaco Optix system they use is somewhere in the $300-400 range. There are cheaper alternatives depending on what you need out of the package though.

    well... it's all about battery life is it not?... personally i think i would go for the low quality lcd with low power consumption, instead of the high quality LCD with high power requirements.... but that's just me :D

    I don't know... if darker lights save battery life (makes sense), why not just give users the option of dimming the lights when on battery power? The G2P allows a larger range of brightness than the others, though I didn't specifically test battery life at various settings. (3 hours per pass of a battery test can take a long time.) Anyway, I'd personally like to have both high quality and long battery life, with the ability to emphasize one depending on my current use of the laptop.
