P-6831 LCD Quality

Given that we know there are at least two different LCD models available with the Gateway FX P-series notebooks, it's important to make it clear that we are reviewing the 1440x900 WXGA+ LCD. The LCD on our particular notebook comes from Samsung, the LTN170X2. As usual, we are dealing with a TN panel, which means worse viewing angles and 6-bit colors. The good news is that the pixel response time is better than older notebook panels (16ms vs. 25ms), and the backlight is rated at 200 nits.

While Samsung states that the contrast ratio is 500:1, it seemed much worse in person and testing confirmed that at least on our particular model the contrast ratio was much lower. Images appeared to be washed out in comparison to other recent notebooks, although we did notice the improvement in brightness. Let's start with a look at brightness levels and contrast ratio.




The white levels are good for a laptop, coming in at over 200 nits. Unfortunately, black levels scale proportionately, and the result is a relatively poor final contrast ratio of around 250:1. We've mentioned in the past that marketing has gotten a bit carried away with the importance of certain specifications, contrast ratio and response time being two of the biggest culprits. The thing is, such specifications are important when they fall below a certain point. It's difficult to tell the difference between a 2000:1 and a 1000:1 contrast ratio, but the difference between 500:1 and 250:1 is very blatant. We're not quite sure why our test results and the LCD specifications differ so much; it could be that Gateway cut some other costs related to the LCD and that's why the contrast ratio is much lower than expected. It's not enough to make us actually recommend against purchasing the P-6831, although if you demand a high-quality LCD you might want to look elsewhere or use an external display.

A new addition to our LCD testing is a look at color gamut. This is something we have wanted to add previously, but we hadn't found any good utilities for generating the appropriate charts and data. We recently found out about Gamutvision, a utility developed by Imatest LLC. They were kind enough to provide us with a copy of their software, and it does exactly what we need. We compared the color profiles of all previously tested laptops to the Adobe RGB 1998 color profile. Below is a chart of the gamut volume for the Gateway P-6831 FX, along with a graph showing the percentage of the Adobe RGB 1998 gamut from the various laptops. Prepare to be disappointed….

Display Quality

We commented in the past about how great the LCD on the ASUS G2P looks in comparison to other laptop LCDs. We now have some more detail as to why it looks better. Nearly all of the laptop LCDs we have tested provide less than 50% of the Adobe RGB color gamut — and note that there are more exacting standards than Adobe RGB 1998. The G2P sets the high water mark at 73.28%, while the vast majority of the other notebooks fall under 50%.

    Ive had this laptop for just over a month now. Cant beat the bang for the buck. I got the last one here in Edmonton for $1350. This was when the price was $1700 in the states I was quite surprised to see such a price difference. Now I don't even see it listed on bestbuy.ca, I wonder if they stopped selling it here in Canada.

    I have just installed 2 of 3 upgrades, another WD250GB 5200rpm HD in Raid0 and a 2nd 2GB stick of ram. I did not however make a backup DVD as was mentioned, and now am looking for some of the apps that came with it. Is anyone that made one of these back up DVD's able to get me a copy? If you reinstall from the DVD that came with the Laptop does it install the aps that was on there? repartition the hard drive for recovery? I installed with another disk I have for ultimate x86. I have x64 on my desktop and had a few problems, but I don't have 4 gigs ram on my desktop. I'm trying to find a T9300 for less than $350 here in Canada but thats seems hard to do.

    Also my ram index rating in the windows benchmark stayed a 4.5 and did not go up to 4.8 as some have mentioned. It lists 4 gigs ram in the post, but of course displays only 3 gigs ram when in vista as a result of running x86.

    I bought this when I was down in Texas on vacation 2 weeks ago, saw what was in it and thought "wow, that's a beast" and then I saw the price tag and my jaw dropped. I immediately went home and found this was by far the cheapest computer with a viable mobile graphics chipset for the performance I wanted if I ever did in fact get a laptop.

    Plays WoW like a champ, and that's pretty much all I got it for; for those who knock it for the processor, it's definitely not bad for what it is, the laptop eats my old northword core 2.4 w/6800nu that I have sitting at work for breakfast. The only thing I can see the laptop really limiting would be strong physics based games, such as Crysis.

    I wasn't even looking for a laptop at the time, but this thing definitely got my attention and I ended up going back the next day and buying the last one in stock. Unfortunately it came with the 1.66 cpu, but it really doesn't bother me since I got what I paid for.

    Speaking of which, a great thanks to the writer of this article for including that it was on sale this week; I like to read reviews of things I buy in a sort of "it was ok to spend all that money since you got a really good deal on it" sort of way, and I ended up going to BB and utilizing their 2 week price match guarantee and got $107.50 back (the $7.50 is from Texas tax going to Illinois tax).

    Overall an excellent review and I highly recommend this laptop to anyone who is considering it. Thanks for the fantastic review and also for saving me some $$

    hey i was looking at this laptop to buy what i mean was is i chose and still waiting to buy but i saw you say the crysis part and i looked at youtube alot and over half the people who showed crysis vids on there was using this laptop (the P-6860 not P-6831 though) just thought to tell you that and it has no lag of what i saw except one guy mad a explosion of 3,000 barrels of oil and couldn't watch or his computer would start lagging a bit Reply

    I played with this laptop at Best Buy when it was on sale for like $1150 or so. I have to say, this laptop has an amazing keyboard. Not just for a laptop, it was one of the nicest feeling keyboards I have ever used. It had perfect spacing and a really nice feel, it gives even high-end desktop keyboards a run for their money. This laptop really is amazing for its price, too bad I don't have much use for it otherwise I might buy one :D Reply

    Superb review! Many thanks.

    I'm in the process of upgrading computers for my house, and I'd like to purchase gaming laptops for their portability.

    Question of the Day:

    The myriad games that were tested are helpful, but there's an elephant in the room that currently has over TEN MILLION subscribers which makes this laptop a very likely culprit for which a gaming computer will be used:

    World of Warcraft

    How would this laptop perform with a 1920 x 1200 external monitor? Any noticeable difference from a 'regular' desktop using a midrange dual core processor and a Nvidia 8800 GT 512MB video card?

    If there's not a noticeable difference between this laptop and a desktop, I'm sold.

    WoW is extremely *un*-demanding when it comes to graphics. Part of the reason WoW is so successful is that you don't need even a moderately powerful system to run it. You can max out the detail settings on a Radeon 9800 Pro card, based on what I've seen, and still run at 1920x1200.

    This laptop has a GPU that is the mobile equivalent of the GeForce 9600 GT, which is more than capable of running WoW at maximum detail... probably even at 2560x1600, although the video output options won't support that. So, if all you're interested in playing is WoW, you'll be very happy with the performance the P-6831 offers.

    To the guy who said laptops are the "losers choice for gaming" - I'm not sure that I agree with that statement, but hey it's the internet so we can all vomit our opinions without actually having to prove what we say.

    I have owned a Dell XPS M170 laptop (Pentium-M 2.0,2GB 533MHz RAM,7800 Go GTX 256MB) since late 2005 and I can still play games like Bioshock, BF2142, World in Conflict and COD4 very easily on med to high settings (Crysis on med, more lowish) on my "ancient" notebook. Oh, by the way, this notebook scores a blistering 3400 in 3DMark 06 (further reducing my confidence that it is a measure of actual gameplay).

    This Gateway should have an equally good lifespan. I don't really see any games being developed that are going to knock this laptop down (seeing as most new games are first and foremost developed for older console tech). Obviously you will have to make some graphic compromises as time goes by, but a $1500 investment (with CPU upgrade) is as good as it gets for the portability/performance it offers.

    The only problem I see is the size (like my M170). I am positive that most mobile gamers like me plug it into an external LCD when at home (or work), so the internal screen is only used when truly mobile (at school, at girlfriends, in the car, etc). For that reason, I think Alienware has hit it on the head with the 15.4" M15x. Small screen, yes, but much easier to fit into a backpack and use at school. The 17" is just way too big to do this and the Alienware is $3000 afterall.

    Gateway would have the one laptop to rule them all if they made a 15.4" version of this under say $1500.

    Anyway, great review. PS - it would be nice if gaming laptops had a movable screen (like the HP 12.1" laptops) so we all don't develop carpal tunnel as we age.

    Great review. I think I found my new laptop. I especially like how you can upgrade it. I've got a t9300, a 2GB stick of RAM, and a 7200rpm hdd lined up to go in when I get one :D Reply

    Jarred, could you give a few more details about the LCD, such as backlight bleed and viewing angles? Reply

    Asus F3kA Seriies, out of the box with 2gigs of Ram, and ATI HD 2600 512 MB Video Card. $899

    I have this notebook. I bought it when it was $1000. I upgraded it to 4 Gigs of RAM, and Run Vista 64 on it. Asus even provides drivers for Vista 64. (Though they tell you they don't support Vista 64)

    I am just curious on the price to performance. I believe the Vid Card in the Gateway is superior, and the processor is as well. But the Asus is very good for gaming comes with a 30 day zero dead pixel warranty, and 1 year accidental damage warranty, and 2 year standard warranty on the rest of the notebook. So the value is extremely good.
