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.

    mainly because they were mainly marketed as screens for 3D and nobody cared enough about 3d especially when they were generally $250-300 more than a basic 1080p60 screen

    oh and when 3D was around the graphics card had a hard time running at enjoyable framerates while in 3D mode. The 980m for the most part doesn't have that issue

    I've seen the overclocks for the 4790K in this chassis and it will hit the OC for a second and drop back down to the base clock speeds. Besides even in a desktop you won't get much more out of Devils Canyon. The GPU has no issues from what I recall.

    I completely agree with you on that one. Don't get me wrong, 4k is a very noticable upgrade from 1080p, but the jump to 120Hz is much more worthwhile imho.

    Unfortunately, to get movies to show smooth motion also requires computationally expensive frame interpolation software (like the SVP project); merely having a 120Hz-capable monitor doesnt really change the way 24fps material is displayed.
    While this notebook is undoubtably quite powerfull (I have been using and upgrading to the equivalent sager/clevo 15" models for the past couple of generations) it will unfortunately not be able to produce even a low quality interpolated 120Hz video stream (4 interpolated frames, from a 24Hz source, produced in a single 8.33ms frame period - ouch).
    So while I (or rather my wife) would love to be able to replace my current htpc (Intel 5960X, Nvidia GTX 780Ti in SLI) with something a bit more streamlined, I don't think this is quite the answer.

    I am, however, definitely going to upgrade my current clevo to this monster asap.

    haha wow nice htpc setup!

    yeah I'm not buying a new gaming laptop unless it has a 120hz display.

    is anyone even selling a gaming laptop right now that has one? Alienware isn't selling them anymore but you can swap the panel out on the new ones with a 120hz panel.

    Why are there never any pictures of the back of the laptop closed, or open? Does this vent out the rear like the Asus G series, or not?
  • Stuka87 - Tuesday, March 10, 2015 - link

    There are two giant vents on the back at each corner that exhaust air. It pulls air in from underneath.
  • SilthDraeth - Tuesday, March 10, 2015 - link

    Yes, I saw the vents from the top down disassembled view. but I wanted to see the assembled rear.

    Sorry -- I usually include these and didn't even realize they were missing until I read your comment. I've added two images of the back (including the ports):
