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….

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%.

    I use the FX for school and my Sager 8690 for gaming. Sager looks plain but preforms likes a desktop, I wish they did a better job on the battery life. But thats where my FX comes in to save the day. Reply

    Obviously Gateway and Best Buy has decided to blow away the competition with this notebook!!

    I have been laptop Gaming for years, because my job keeps me on the road alot. It is a great way to pass the time away from family, and stay out of trouble.

    I currently own a Sager 17" laptop with the 7800m 2gb, and a 80gb hd. When I bought it new it was $2200.

    As a comparison to the Gateway, (Best Buy version)get an almost equivalent system from Sager, your looking at $2200. In all fairness, that is the 8800gtx ($395) and a 2.1 ghz (t8100) with no option of a second HD, let alone Raid 0. It also has the fingerprint scanner.

    To me the 2nd hd (even though 5400) is very important, let alone the potential for raid 0. I find that laptop HD performance is not very good overall, and can cause delays when gaming.

    Screen resolution, I have been gaming at 1680x1050 and in all honesty, it is too high for a 17" screen. Especially in the desktop. 1920 is way too high for a 17" screen, unless you have SLI8800m's. That is a completely different bracket.

    In my opinion they did an excellent job in trading off, and adding in some very key features. SO you basically save $1000.00 for a little bit less performance than a 8800 GTX machine. The key here though is at @ $1200, not $2000 you get a machine that will be able to handle just about anything you can through at it (Crysis doesn't count).

    If you are thinking about getting a laptop, for gaming...this is the absolute best smoking deal you can find!!

    Anybody have an update on when the P-6860fx will be out? Reply
  • Rekonn - Friday, April 11, 2008 - link

    Found answer today on Yahoo finance:

    The Gateway P-6860FX comes with Windows Vista Home Premium 64-bit Edition with SP1 and will be available beginning this weekend at Best Buy with a manufacturer’s suggested retail price of $1,349.99. It comes with NVIDIA® GeForce™ 8800M GTS 512MB GDDR3, an Intel Core 2 Duo T5450 processor, 3072MB of DDR2 SDRAM and a 250GB(1) 5400RPM SATA hard drive. This system also comes with a multi-format dual layer DVD-R/RW/DVD-RAM drive with LabelFlash technology(2) for burning images and text onto a DVD or CD.

    I've returned both my P-6831s because of the P-6860FX... the above post is a bit wrong about the specs... here's what I know:

    Gateway P-6860 FX
    Basically the same as the P-6831 with a few nice upgrades:

    Proc = T5550 @ 1.83-1.86Ghz (up from T5450 @ 1.6Ghz)
    RAM = 4GB (up from 3GB)
    HDD = 320GB SATA (5400rpm) (up from 250GB)
    OS = Vista Home Premium SP1 (64bit) (up/down from 32bit?)
    MSRP Price = $1,349.99 (same price before BB $100 off online)

    All other hardware appears to be the same... there's a small chance that the CD-Burner supports one more Dual Layer format, but that could simply be because of Best Buy not listing specs correctly.



    Side note... has anyone had issues with the right speaker having bad distortions on certain sounds or speach from games... both my P6831s had this issue (another reason I returned them).


    TK.



    HEY, Anandtech.com.... any chance we can get a refreshed review including the P-6860... it would be interesting to see if the extra boost of Proc and RAM with 64bit OS helps or hurts the laptop.

    ***please, please, please, please, please***

    You did forget a couple of other differences.

    BTW Get this Laptop at Best Buy!! The upgrades are well worth it as compared to the Gateway website!!!

    1) Comes with the Bluetooth the Gateway 172s does not
    2) The wireless adapter is the upgraded to support b/g/n
    3) 64bit operating system vs 32bit

    Thank goodness you can Raid 0 this puppy later, I was worried! The specs for the 172s says no raid support??

    aye, a refresh on the review for the 6860 would be great :) Reply
  • Rekonn - Tuesday, April 22, 2008 - link

    Yes, please update the review! I'm planning to buy a laptop soon and would love to see how the faster Proc, more RAM, and 64bit OS affect results. Reply
