A Tale of Two LCDs

Laptop LCD Quality - Contrast

Laptop LCD Quality - White

Laptop LCD Quality - Black

Laptop LCD Quality - Color Accuracy

Laptop LCD Quality - Color Gamut


Clevo P151HM / CyberPower X6-9300 Gamut


MSI GT680R Gamut

As mentioned earlier, the LCD on the MSI laptop is noticeably inferior. The sad thing is that both the MSI and Clevo use the same AU Optronics B156HW01 LCD panel, but Clevo uses v1 while MSI uses v5. Presumably the v5 panel is a lot cheaper—at least it better be, judging by the results shown above!

On the other hand, the P151HM has what is very likely the best laptop LCD I’ve used in most areas. An 800:1 contrast ratio is great for a matte LCD, color accuracy is reasonable, and color gamut is close to ideal for the sRGB space. If you’re after a high gamut panel, there are better options, but most people feel high gamut panels just end up looking oversaturated. I really wish we could draw a line in the sand and have the P151HM panel set the minimum quality level that laptop displays should reach, but instead we have a race to the lowest priced LCD notebook manufacturers can find, which is why we see so many 1366x768 laptops.

Not only does the Clevo notebook offer superior contrast, but it also offers better viewing angles. We’re still dealing with TN panels either way, which is unfortunate but difficult to avoid, but the P151HM has a much wider sweet spot for viewing.

Noise and Temperatures

MSI GT680R

CPU temperatures are about 5C lower on the Clevo when the system is under a heavy load for a long time, but the GPU runs reasonably cool in both notebooks. The catch is that the Clevo only manages this by ramping up fan speeds much earlier than MSI.

At idle, the MSI GT680R maintains a constant 34.5dB output (for around 12”); in contrast, the Clevo oscillates between 31.9dB and 35.6dB. What’s truly unfortunate is that the Clevo is the more annoying under light workloads because you notice the frequently changing noise level more than you would a steady drone. Under load, the noise situation falls even more heavily in MSI’s favor. After looping 3DMark06 at 1080p for over 30 minutes, the MSI still maintained a reasonable output of 39.1dB, and it would even drop to 36-37dB at times. The P151HM on the other hand quickly ramped up fan speed to what appears to be the maximum RPM, putting out a loud 44.3dB. Under our worst-case load (4-thread Cinebench with 3DMark06 looping), the MSI also had to increase fan speed to 44.0dB and the Clevo maintained the same 44.3dB output, but most users likely won’t be putting a 100% load on all CPU cores while loading the GPU at the same time.

Looking at the cooling arrangement, MSI actually does something quite useful. The chassis at first appears to have a rear and side vent, but it turns out the rear vent is actually an air intake. Instead of trying to pull air through the bottom of the chassis like most notebooks, the fan gets easy access to fresh air at from the back, and vents it out the left side. ASUS’ G73 chassis is still the quietest gaming notebook we’ve encountered (though we’re not sure if that translates well to the smaller G53 chassis), but the MSI cooling arrangement tends to work well. It would be nice if they could reduce idle noise levels a bit more, but a steady 34dB is better than hearing the fan spin up and then slow down ever 10-20 seconds.

    So, you want a GT555M? Me too! Check this out: SAGER NP5165 (Clevo W150HR)

    No, I want at least the performance level of GTX 460M, but with Optimus enabled. :-)

    Jarred - great review as usual - thank you, appreciate your work.

    I've been looking for a new work machine for awhile with a good screen being the priority - After reading your review, I called the Cyberpower people in the UK - http://www.cyberpowersystem.co.uk/ and am looking to order the X6 - 9300 shortly.

    The guy in Cyberpower said that the model has refreshed in the UK with a NVIDIA GeForce GT 555M 2GB GDDR5 instead of the 460. I'm still not sure if it has Optimus enabled, but it should be fairly efficient even without it. I'm hoping this model will also have a lower fan noise because of the slower gfx card.

    Apart from the look of the bezel - Assuming the fan noise isn't so bad - then the only real problem in my eyes is the very poor keyboard (which is a problem, but the screen compensates a good deal) - For the price you get a good panel, probably not that far away from a HP Dreamcolour, the 95% FHD display of the W510 / W520 or the Dell M4600 IPS (which is a 400 euro upgrade).

    So would the keyboard drive you mad long term?

    I was also waiting to see a review of the new M4600 - Have you got your hands on the precision M4600 yet? Insterested in that screen (And the precision will probably have a fantastic keyboard as well) but the price is the problem - probably a net 1k difference in both laptops (of course very different target market and build quality.)

    I know it's very strange to bring up the x6 - 9300 vs the Dell M4600 - but I am also so fed up with the quality of laptop screens over the last 6 years, I just want a laptop with a great screen above everything else, followed by price. I will do very little gaming on the x6 - 9300.

    Thanks again,
    Paul.

    I can live with the Clevo keyboard; I just have to "remap" my brain to using the number keypad for the Home/End/PgUp/PgDn keys. I'm pretty sure the notebook model you're looking at is the Clevo W150HRQ (seen here: http://www.avadirect.com/gaming-laptop-configurato... so it supports Optimus, which means better battery life. The only real question is what LCD they're using -- AVADirect says "glossy", where the P150/P151HM that I've tested both had matte LCDs (neither one from AVADirect, though). If it's the same matte LCD as the P151HM (X6-9300) reviewed here, I'd probably go for it. It's a little slower on the GPU, but better battery life and presumably a slightly lower price.
