Clevo P750ZM LCD: 4K IGZO

HiDPI panels are becoming increasingly commonplace, and while there are still compromises involved (e.g. at least a few games that we tested didn’t like having scaling at something other than 100%), it’s definitely more of a future-looking decision. I’m not sure anyone other than an eagle would really use the Windows desktop at 4K with 100% scaling on a 15.6” display, but that option is always there. Personally, 2560x1440 would have been more reasonable, and you can even add that option via the NVIDIA control panel (which I did), but IGZO does generally mean you get one of the best quality panels currently available. Let’s see how it looks.

Display - Max Brightness

Display - Black Levels

Display - Contrast Ratio

Display - White Point

Display - Grayscale Accuracy

Display - Gamut Accuracy

Display - Saturation Accuracy

Display - GMB Accuracy

Uncalibrated, the maximum white level of 350cd/m2 is good if not chart topping. The black level of 0.29 nits at max brightness is also great, leading to a roughly 1200:1 contrast ratio. However, we noticed at lower brightness settings that the contrast trails off – we measured closer to 1000:1 at 200 nits for example. The average CCT isn’t perfect but it’s not terrible. Still, looking at the various delta E results shows the display could benefit from calibration.

Post-calibration the LCD is nearly perfect in most colors, with a few that still fall above 3.0 dE. Most of these problem colors are orange or blue hues, but there are plenty of close colors that are well below 3.0 as well. The greyscale Delta E is essentially perfect, as are the primary colors, but the saturations and colorchecker results are a bit higher. In short, it’s a great display overall and better than most other laptop panels…but it’s still not perfect.

    So you got a sample from Clevo resellers after all ? :)
    Now that's a laptop.
    Are you considering to review Clevo P651SG ? Less bulky and scary :)
  • Flunk - Tuesday, March 10, 2015 - link

    No, that's a desktop replacement. You don't want to put that thing on your lap. Still, it works for the segment it's in, top performance with near-desktop bulk.

    We can certainly try to get the P651SG for review to see how it compares with the others. I suspect it will be quite similar in performance to the Gigabyte P35W v3 review I'm working on, so it's more a question of whether you like the Clevo design more.

    It would be nice to see whether the desktop CPU really gives an edge in games over the mobile 4720HQ in the P651SG. The latter has soldered GPU and CPU though.

    They crammed a 4790K into a laptop?! Thats gutsy. Although I suppose not technically a laptop, more like a portable workstation. I think if it was mine I would choose a 4690K over the 4790K, they run noticeable cooler, even when overclocked to the same speeds.

    I used to be a consultant visiting 2-3 clients a week working on their systems but my laptop was my testbed. The software was like a 747, doesn't matter if it's one or a hundred clients but it was a heavy beast to get off the ground. That's exactly the niche this machine is built for, high specs/performance running on-site, on power but portable between installations. I even used one with a defective battery for a year or so, didn't matter.

    with the Clevo P577wm having had extreme desktop CPU and 2 GPU's so this has been done for years, though this might be the first 15" notebook to go with a desktop cpu.

    Not quite my friend. May I introduce you to my Eurocom, from 2000, 1st 1GHz Desktop CPU in a laptop, with 133MHz FSB.

    It was fully loaded, and around ~$5k at the time, coming with a MASSIVE 512MB of RAM.

    The fact that it had built in Firewire, V.90 modem, dual PCMCIA, dedicated video card with a whole 16MB of vram, dual HDDs. What I really liked was the screen, resoultion of 1400x1050 at 15", which still betters some craptops sold today.

    Also, a bit of a timeline on Eurocom (and thus Clevo, in effect):

    The keyboard and build quality / aesthetics were pretty poor though. I gave it away to a buddy in 2008, and he seemed quite pleased with it. But man did it get hot, as did the 1.7GHz one I had about 5yrs later (also a desktop cpu). My M570RU (with mobile cpu) was much, much better though, in every way.

    I'm pretty much an Alienware convert now though, but I could be tempted if price, spec, and screen were right...

    88W ? There's no way it's an 88W chip. Even the desktop version is 4790S which is 65 watts. And Haswell mobile is 47 Watts with most of the performance. The MSI has double the battery life.
  • flyingpants1 - Tuesday, March 10, 2015 - link

    Wow. Just.. wow. I understand desktop replacement, but 4790k overclocked is overkill.

    Is there a version with GTX 980m, but without a desktop CPU?
