Centrino 2 Laptop Roundup

Display Quality

The last area we want to test is the display quality. We have stated repeatedly that laptop LCDs pale in comparison to typical desktop LCDs, and unfortunately we see that trend continue. We test color accuracy using ColorEyes Display Pro, and we test with two different colorimeters. The first is a DTP-94 we have been using for some time, but we have added an i1 Display2. We test both colorimeters with ColorEyes Display Pro, generating both LUT and Matrix color profiles. The reason we do this is that some displays respond better to LUT profiling while others work better with Matrix profiling. We select the best result out of the four tests for our color accuracy charts. The change from Monaco Optix XR has also invalidated our previous color gamut results, so we will only have color gamuts for select laptops. (We use the matrix color profiles for gamut, as they usually have ~10% higher gamut volume.) We will also report the maximum LCD brightness and contrast ratio.

Out of these three laptops, the ASUS G50V is the clear winner. In fact, when you consider contrast ratio it's not even close. Color accuracy is actually quite good on all three laptops (though still not at the level of what we see on a decent desktop LCD), but color gamut is another extremely weak point of laptop LCDs. The poor contrast ratio results for the ASUS U6V in particular are disappointing; we had hoped that all LED backlit panels would show improved contrast ratios and color gamuts, but clearly that's not the case. Given the choice, however, we would still take the Acer 6920G LCD over any of the other current offerings.

Also worth mention is that the trend to use glossy panels continues; all three of these laptops come with glossy panels - the HP dv5t unit has a "designer glass cover" similar to what we see on the newest Apple MacBooks - so reflections can be a problem. Using any of these notebooks indoors never bothered us, however, and outside of the HP they don't seem to be quite as reflective as the Apple offerings.

    See http://www.anandtech.com/mac/showdoc.aspx?i=3435&a...">Anand's article on the subject. The MacBook battery life dropped in half with Vista... but then that could just be that Apple didn't optimize for Vista properly. What we would rather see is a Vista PC that can compete with MacBook; I can't think of a good reason why it can't be done, unless Vista just has some junk that refuses to allow power saving features to fully activate.

    I think it is only fair to the other laptop manufacturers that you at least show the battery life of a Mac running Vista alongside their favourable results, I doubt anyone is still allowed to supply review samples with XP... it's not their fault Vista is crap!

    The VAIO SR series claim 6 hours of battery life running Vista. This is a 13.3" notebook with a 6-cell battery. Can you guys verify this claim, ask for a demo unit maybe?

    I'll see what I can do; Anand has had Sony hardware in the past, so maybe he can get me a laptop from them.

    Supposedly the SR also has "battery leakage" issues as well where it will drain over time even when it's off. I have a Z series and can hit 4-5 hours myself. That's at about 50-60% screen brightness, wifi on, pretty much everything else disabled, in stamina mode, with the processor pretty much sitting at Super LFM the whole time.

    Still rocking this laptop today, with an X9100 Core 2 Duo Penryn at 3.45GHZ via multiplyer overclocking. Installed the 17 fin Forcecon fan while I was at it, the same that's comes with the Asus G51VX and G51J for more airflow. 8GB of RAM.
    Still my main machine today. Refuses to die even with a few years of nearly 24/7 GPU & CPU thrashing at 90C +.. The chassis is beat up though, starting to crack on the main chassis around the hinges. But, can get a used 1 on Ebay for cheap.. Batteries no longer made for it so i have a few genuine 9-cell batteries in my fridge.
    About time to upgrade to a Coffee Lake laptop maybe, but I like my Windows 7 setup.

    If you want to long time use your laptop then HP is the best device because its processing system is so fast. And it have more storage and battery life is also good. And the best thing <a href="https://hpetechnicalsupportnumber.com/"> HP Support Assistant</a> always available for customer help.
