    I recently purchased an EVOC Clevo P650HS-G from HID evolution and chipped in for the faulty pixel warranty and for the backlight bleed minimization. Since the value of this choice arises from time-to-time...

    The first thing I did was activate the laptop by plugging it in, then immediately checked the screen by popping in a flash drive with the portable freeware_DPT.exe, Dead Pixel Tester http://dps.uk.com/software/dpt, which has a variety of patterns and 16 color screens that are helpful if your color vision isn't perfect RGB, or if you think staring at Dark Yellow is way more fun than staring at RED. It has a helpful utility for marking putatively faulty pixels (see pic) as well as a "dead pixel exerciser", for which I have no idea about it's efficacy.

    Turns out a lot of faulty pixels disappear if you clean the screen (lol)

    I'm happy to report I didn't find any dead pixels on immediate boot, a month later, or now (~2 months). So, either I'm really bad at detecting faulty pixels, or the guarantee was worth it. Either way, I'm satisfied.

    DPT also has a black screen that's useful for checking for backlight bleed. My first impression is that backlight bleed was obviously noticeable in the righthand upper and lower corners and at one bright point near the taskbar search box. In a blacked out room with the monitor brightness at 100%, the corner bleed was substantial and the bottom-left light exit point was like a little flashlight. Of course that's not how I plan on using my laptop, and with the monitor at 30-40% in a normal computing environment the corner bleed isn't noticeable, and even in a dark room with a black screen displayed only the upper corner shows a faint yellow tinge.

    The lower point source of light was more problematic, but it reduced by at least half after relieving a little bezel pressure. After a few days of raising/lowering the lid paired with a very slight retweak or two, it settled into it's "rightful" place, and it is similar to the upper corner bleed though a bit brighter. In a normally lit room the point source bleed is not observable; in a dimly lit room with a black screen it's noticeable even at 30-40% brightness, but not on the blue/black Win10 desktop.

    Perhaps the backlight bleed guarantee was worth it, perhaps not. My previous panels weren't IPS, I don't have a slew of new P650 screens for comparison, and I certainly don't know the batch of panels HID received, so it's all subjective and qualitative... and since it comes down to perception (eyeballs and wallet), I'm going to say I'm satisfied with the backlight bleed minimization guarantee as well.

    Cost for minimizing back light bleed is a bit much tho.

    My screen came with a good bit of bleed because I didn't pay extra for it. Sorry state of affairs when you have to pay extra to get a good screen on an already expensive laptop.

    True on the cost, but if the quality range in production is that wide, you either have to take your chances or pony up the cash.

    Here's part of my rationale:

    If I don't pay for the 'insurance' I may get a nice display with a good bezel assembly, or I might not.
    If I'm not satisfied with the display/assembly I'll have to:
    • hope the bleed is bad enough that the seller sends out an RMA. Knowing that 80% of the screens are deemed 'less desirable' indicates that a pretty small proportion must be classified as unworthy (and it's subjective)
    • wait once again for my new laptop...
    If an RMA isn't sent, and I want the reseller to exchange the display, I'll have to hope the reseller will:
    • not make me pay the full shipping costs
    • not make me pay for labor
    • give me a discounted price on the new display (likely they would do their best to make sure it was a better display, but that's reseller dependent).
    • Even with getting a good deal from the reseller, I'd be at least buying the display twice.
    • (and you still have to wait once again for the laptop)

    • The other option is just to source, buy, and install a replacement display myself. It's possible to get a screen for less than a $100, but when it's all said and done you've already paid for a screen and half no matter what.
    Better just to chip in, have them select the 'best' of the lot, and know you have a very strong argument that they need to RMA it pronto (and throw in a new keychain or two) if they let a crappy display/assembly slip by.

    Not really a sorry state of affairs...it is the nature of IPS panels, and is therefore going to be present to some degree or another on any laptop with an IPS screen.

    The alternative is...??

    The alternative is good QC sourcing only the best panels for you for the high end laptops you sell instead of making customers pay extra for what should be a standard feature at this price range.

    Well, not exactly. If Clevo, or any of the manufacturers, did that, the base price would have to raise significantly, and you would have to throw away about 80% of all IPS panels manufactured.

    Unfortunately that is a wonderful pipe-dream, but it is just not a reasonable expectation.

    As far as I know, HIDevolution is the only company offering the Minimize LCD Backlight Bleed option. Buying from anyone else...you get what you get...it is a pure lottery.

    hahaha! so true! some people just cannot read between the lines!

    No I would rather cheap out on a 100 USD fee, take my chances, get a crappy screen, then go and complain and deal with the hassle of returns and wait for ages without a laptop because I wanna save 100 bucks.....NOT! :rolleyes:

    I'd pay for quality any time of the day

    Yep. Minimize backlight bleed is worth it. With HID's options, you can get the exact laptop you want, with realistic expectations. CPU that can overclock well, a panel that looks like it's worth the cash you spent. And Xotic PC only offers the dead pixel warranty (which most people offer). Only HIDevolution offers this AND minimize backlight bleed.

    I don't know why people think that HID actually MAKES the laptops. Clevo makes them. Hid only puts the other components in and makes it ready to use like a boss.

    Now if only Clevos had the MSI Steelseries keyboards.... right Phoenix? :)

    OLED baby. Time for The Laptop industry to move on.

    The first Thinkpad Yoga and Alienware 13 OLED panels are now 2 years old and have not shown any big issues.
