Dead pixel/backlight bleed warranties from HIDevolution

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.

Spoiler: DPT- color to black

Spoiler: DPT-yellow, marked

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!

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.

 

Oh I never knew OLED screens were available for laptops!

by the way, you have an extra [/FONT] text in your signature after your Gaming Badge Image

 

Yea, They were launched in January 2016 CES and made it through all revisions into the current 14" X1 Yoga and Alienware 13

The HP Specter X360 OLED in the article never made it to the market as far as I am aware.

As you may or may not know... OLED technology does not use back-lighting and has perfect contrast levels as well as ~100% Adobe RGB and ~100 sRGB. Also better response times than IPS panels. It really should be the next step for Laptops

 

Nature of IPS is light bleed, well helo beautiful LOL
I have 6 IPS panels to look at...
1 has backlight bleed SONY 49 inch tv (IPS panel)...IPS monitor doesnt...IPS on 2 phones doesnt...IPS on tablet doesnt...
So im my no brain experiment I can conclude backlight bleeding is not in IPS nature...
it is in I dont give a fook about my costumers nature...and if some machine asembly part can assemble 100 display panels before
it needs to be replaced why not assemble 1000 display panels...
While there are sheeps there will be woll

 

Indeed a 'no brain' experiment.

Phones, tablets, desktop monitors and TVs are not laptop screens.

Also, have you tested in a completely dark room, with just a black background on your screens.

Now, you should do a bit more research on the issue before making such a post. Oh, and use Google translate if English is not your first language...or, if English is your first language, pay attention to Spell Check. Your Profile says you are 40, but your post says otherwise.

 

He said that about IPS panel nature...while it is just big fat lie, and you jumped on that train...what does that tell us...hmmm...
Even it is no brain experiment, you failed observing the point.
Real issue is bezel asembly and design.
I can see why you are rooting for this nonsense.
Company you represent will charge people extra cash for minimal light bleed.
While that is what they should get in the first place.
And who is to tell what is the amount of that light bleed caused by bezel twisting panel they should agree on?
You
That is so cute...

Edit: I tought someone else said that about IPS panels, but it was You! @ Donald@HIDevolution

 

Let's not derail my (hopefully informative) thread. I'd hate to unfollow my own post!


I know this topic isn't as riveting as a describing a magical triple 1080 SLI laptop with 128GB of RAM, but comparative reviews regarding pixels/bleed from other purchasers (from HID or not) would be more interesting!

 

you can actually minimize the bleed by yourself. it's a bit tricky though.

 

I echo this! I have personally fixed over 100+++ backlight bleed problems. in most cases the problem lies in the twisted bezel, too tight bezel fastening, LCD backlid twist or LCD screw mount bending.
more rarely the LCD panel frame bent, which is the simplest fix of all!!

 

@tanzmeister
Thanks for the heads up and sounds like you have lots of experience, much more than my guessing and trial and error to reduce bleed on a sample of one.

I'd be interested to see a few example pics demonstrating the most problematic points to check and adjust. Not really a guide per se, since bleed will vary between displays, but something a long the lines of 'twist this' or 'look here'
Possible?
