is it just a pipe dream to actually get a monitor with no dead or stuck pixels and no backlight bleed?

I just purchased a BenQ Gw2765 and it has one dead pixel in a fairly prominent place and backlight bleed I can actually see in the day time along the left side on black screens.

It seems like most monitors have these issues, so do you think it is worth it getting a replacement for these issues, or is it just a losing battle?
 
I don't think one dead pixel is uncommon but the backlight bleed sounds really bad. If you bought it from a respectable retailer like Amazon or Newegg I would definitely exchange it. Amazon has been great with my recent monitor purchase. They will send you a new one and you have a whole month to return the original that way you can compare them both and see which is better. I had a bright dot (stuck pixel) on my first PB278Q and this monitor in particular has a zero bright dot policy from Asus so I find even one to be unacceptable. I would rather sort it out with Amazon than wait and risk Asus's customer service which seems to have a bad rep.

Some other retailers you have to be careful for example Best Buy limits the amount of returns you can do in a year to only 3 even if one of them is a $15 dollar cable or something trivial like that.
 
You have to get lucky, unfortunately :( Or you have to buy and request testing it in a local shop.

My XL2720Z has no dead pixels and the backlight bleed is about as low as humanly possible for a TN, literally perfect. There are some very very minor light/dark tone variances around the center (every TN panel has this, even the TFTcentral review shows that), but if this were a panel lottery, I would have won $100,000 dollars.

I got lucky since it was shipped from Benq's webshop. Maybe they tested it first...

So yes, it's possible to get a nice panel. You just have to get lucky, or test one locally.
 
I absolutely dread buying new monitors. So many dead pixels and backlight bleeding out there. I've returned 7 monitors in the last 6 months because of dead/stuck pixels, stuck dust, and/or horrible backlight uniformity. And all 7 monitors were $800-$1000.

From those 7, how many were you aiming to get? Surely that wasn't 7 monitors to find just one good one...?

What monitor(s) were these?

And who were you buying from that was so kosher with returning that many?
 
I bought an Asus pb278q from staples and had no dead pixels or backlight bleed.

Guess I'm lucky.

I'm just looking for one good one. Can't seem to find one. =/

I went through 4 Swifts, 2 Dell Ultrawides, and the new Acer 144hz IPS.

Bought from Amazon, Newegg, TigerDirect, Microcenter, Dell.
 
im 5 monitors deep at this point and all have had either dead/stuck pixels, excessive bleed or dust stuck in the screen.

the one I have right now has no pixel issues and minimal bleed but has dust stuck about 1/4 inch in on the left side. I'll try one more advance return(dell) but if I get another dud I might just keep this one and give up.

I don't understand why its so hard to make a defect free monitor. drives me insane.


EDIT: for those that have stuck dust does it ever move or drop to the bottom out of sight?

If you are happy to send it back again and again until you eventually get a perfect one... You will have probably given up before then and settled for one which is "just about ok"
 
Never had a bad/dead pixel but I just live with the lighting uniformity issues of cheaper monitors. I don't need an expensive monitor so I typically stay under $200 when buying one.
 
That's exactly why I won't be upgrading my XL2720Z any time soon.

My first VG248QE seemed to be ok initially and only had mild brightness uniformity in the center of the screen, besides that it was nice, but it later developed a stuck subpixel (red, maybe?) below the center of the screen. Wasn't dead which means blue was correct but for some reason, on a white background, the pixel was red. (ok that I don't understand). Maybe I'll doublecheck later.

The second one had a huge gigantic vertical red pixel bar from top to bottom, that was there the instant the screen was powered up, before even being connected to a computer. That got RMA'd instantly. I complained to newegg about that monitor being shipped from Tennessee when I was in California and that it should have been shipped from their Industry, CA warehouse, and requested directly that the replacement get shipped from Industry (since I'm right next to there anyway), since I told them it looked a LOT Like the Tennessee box had been dropped and thrown around.

The third one had (and still has) no dead or stuck pixels, but the same type of minor brightness uniformity issues as the first (not backlight bleed since this was around the center and seemed to be light/dark uneven horizontal patterns. Mildly annoying on grey backgrounds but otherwise acceptable like the first. Both panels had 'some' backlight bleed at the bottom but it was very low. Compared to the things some of you are getting, you might even call it near perfect. I just didn't really like that on both of the screens, when moving or gaming around on light/greyish backgrounds, you could see the light/dark/light horizontal shift, but both were otherwise good panels (besides the stuck pixel).

The XL2720Z was a complete slam dunk, though. No backlight bleed, even lower uniformity issues (yes it's there but not noticeable except on test grey screens) and as perfect a panel as anyone would be happy with. If only this were IPS instead of TN........ :/
 
Eizo or NEC flagship with uniformity compensation on. There ya go.
 
So I did an exchange for a new one and no dead pixels spotted so far, but I do see a cyan coloured pixel in the centre of the screen up from the bottom a ways. So I've exchanged the dead pixels for a stuck one apparently.

Backlight bleed seems better, still an L shaped bit in the one corner, but the IPS glow kinda masks that to a certain degree. Still need to look at when it gets dark out to check properly though.
 
My Swift was a pixel perfect version with no noticeable BLB (the light is only visible when the screen is completely back, otherwise any sort of color masks it).

As others have mentioned, the only issue with this monitor is the fact that it is a TN, But once I sit back on my chair with controller in hand, the shift/crush was barely noticeable. So far after 6 months of use I have not yet developed any issues with it. Although there was some odd colours coming from some white letters on the desktop, I am not sure whether that is windows or monitor related. In any case there are no issues when displaying an image.

I guess I got lucky. According to the manufacturing code, my Swift was made in October, I bought the monitor in December.
 
Man I just got really lucky with my BenQ. I got it a couple weeks ago and it had zero dead pixels and while I suppose there is some backlight bleed, it doesnt bother me and doesnt make things look bad. The stuck pixel thing I could never live with though. I would never be able to draw my eyes away from that one wrong spot on the screen. Guess thats why when I first fired this thing up and pulled up an all black then all white screen and saw nothing stuck, I gave it a big fat kiss and left well enough alone.
 
This is the reason I'm scared to upgrade and why I still sit with my first LCD monitor ViewSonic VX2268wm 120Hz from end of 2009 which has zero pixel defects and "acceptable" bleed lol. I can't stand this panel lottery race, I can't either understand why there's no more active push for OLED monitor development. It can't be that lucrative for manufacturers with that shitload of returned monitors.

LCD should just die a horrible and fast death, it's a poor tech to be 2015 technology level standards.
 
You think about it, it really is unacceptable to have 1 dead pixel... Sorry but we are paying for a product and we want X product to be 100%.

Do you buy a car with a scratched paint job? missing windows..or a light in the dashboard that doesnt work..

the dead pixel policy is a lame excuse to have crappy QA.

On that note between me and work, i would say i have bought 40+ LCD's over the last 3 years and not 1 has had a dead pixel.
 
So I exchanged my last monitor for three stuck pixels and am on a 3rd one now. This one only has one dead pixel up in the top left corner which I'm really fine with at this point, but it has bad backlight bleed.

I'm fine with some backlight bleed and really I expect it, but this is too much of the screen covered with it. So I'm going to end up returning this one as well. Really frustrating experience at this point considering the picture quality otherwise is good.

Not sure what I'm going to do at this point.
 
Does anyone try the massage trick anymore? I think that might work on stuck ones vs dead.
 
Dead pixels are extremely common with IPS panels (although very uncommon on 1080p displays these days) in 2560x1440 and 3840x2160 displays. Especially big displays. Even a $3000 NEC 4K monitor will have dead pixels. It's just hard to avoid on newer manufacturing processes.
 
Yup. Don't accept defective products. The only reason dead pixels are common is because dumb consumers accept them. If there was zero tolerance for dead pixels, and they were all returned, you'd see quality control mysteriously rise to offset costs.

They're getting away with selling defective products.
 
So here is the final count on the BenQ GW2765HT.

First monitor: 2 dead pixels, bad backlight bleeding + clouding
Second monitor: 2 stuck pixels, bad backlight bleeding + clouding
Third monitor: 1 dead pixel, bad backlight bleeding + clouding
Fourth monitor: 1 dead pixel, bad backlight bleeding + clouding, defective DVI port, missing DP cable
Fifth monitor: 0 dead pixels, bad backlight bleeding + clouding + missing manual/CD

Plus the DisplayPort has issues with multiple monitors where it'll disconnect when you power off the monitor and not re-connect until you unplug the cable and plug it back in.
 
yep I also have no sympathie with the manufactures. return if's not good. my friends call me crazy because it returned 3 monitors with horrible bleed, but I think I'm doing it right. they sell low-grade trash.

I wouldn't find paying 100$ more for a good QS. But it's also a problem with more expensive tfts.

i beg to differ. Grade A+ displays are supposed to be pixel perfect. Dell promises pixel perfect displays on all its line of mid end to high end monitors, and Dell does not have the best brand on this subject.

IPS has backlight bleed, Bigger IPS have big backlight bleed. The amount of bleed will vary, but can induce bleed even on a " almost perfect" monitor with minor warping of the screen, following a change of place in the desktop, a temperature change. If anything, i would say that newer IPS panels, with higher contrast like 1:1000 are slightly less prone to BLB.

You want no-BLB, grab a VA panel. You want a pixel perfect no-BLB monitor, choose a grade A+ brand, like the philips 40".

How is backlight bleeding, often issues by the pressure on the panel due to shit factory design and construction, related panel type and tech?

let us reverse the question: point us toward a thread [H] where a users complained of BLB on a VA panel.

VA ability to block light is not as affected for minor screen warps unlike IPS screens, where a fraction of milimeter warp can result in massive BLB.

To make matters worst, IPS has less transparency, so it needs stronger backlights to output the same luminance.

BLB is mostly an IPS issue, rare among TNs and unheard off between VAs.
