online retailers and dead/stuck pixels

[h3ndrix]

Hey,

Anyone know of any US online retailers that do a dead/stuck pixel test for a price before they sell the monitor? I am in the market for a Sony SDM-P234 and would like to have it tested before I buy it.

Thx.

Dead and stuck pixels are one reason I still prefer a CRT. The other is that the picture on a good CRT still blows even the best LCD's away.

The only number of bad pixels I would find acceptable is ZERO. I don't believe any manufacturer guarantees that, either initially or over the warranty period. If you want zero bad pixels, buy it from a brick and mortar company where you can view it before you take it home or with an agreement that they will allow you to return it for any reason.

I have personally owned 5 and worked with countless LCDs and have NEVER had a dead or stuck pixel--not one.

BTW, every single one of these LCDs was ordered online. From Dell, to BenQ, to Gateway, to Mac, not a single bad pixel.

I saw a couple of LCDs on Newegg where the manufacturer guaranteed zero dead pixels. They weren't outrageously priced either, but they also weren't major brands.

Dell I believe is very good about returns if you find dead pixels. Quite a lot of other brands are the same way, but of course they don't advertise it as a guarantee, and most retailers won't advertise it either. Most brands have policies that count how many pixels are dead as well as their location on the screen.

Directron has a no dead pixels guarantee for 19 dollars. I'd bet if you contacted dealers who build custom systems that provide "build and burn-in" services, some of them would be willing to do the same thing.

The first LCD I bought for myself has a single stuck pixel up near the top right corner. It doesn't bother me, and the thing was on clearance at CircuitCity and was a half hour drive to buy it. Wasn't worth trying to get it replaced, since it was on clearance and was one of only two at that store and apparently no other stores inside an hour's drive had any, and it was a cheap StarLogic branded unit, I didn't expect a great warranty/guarantee on it.

Stuck pixels become rarer and rarer as time goes on and processes get better at the manufacturers. They were almost expected on desktop screens just a few years ago.

The vast majority of commercial LCD monitors are "class II" devices. This allows up to seven defective subpixels per million pixels.
However, manufacturers often have their own definition of what's to be considered good. Check the manufacturer's specification before you buy!

Philips for example have a range of "Perfect Panel" monitors which they guarantee to be just that - perfect. Unfortunately they haven't extended that past 19" yet.

One maby two dead pixels really isn't that much to worry about. And if it's stuck sometimes you can gently get it out/unstuck.

I've only owned 2 LCD's. The first might have had a few dead/stuck pixels but it seemed a lot of them had that. My VX2025 is perfect. No dead pixels. And not a lot of the reviews say dead pixels either.

I recently bought a new LCD, and in the process of doing the research, I learned something I didn't know. The article I read said that after LCD panels are manufactured, they are sorted into 3 catagories. The best panels go into the "Professional Series" LCDs, the next best into the mid-range LCDs and the lesser panels into the "value" LCDs. This being the case, if you buy a "Pro" line LCD, it is unlikely that it will have bad pixeles.

I don't have a link to where I found this information, but maybe someone with knowledge of the LCD manufacturing process could expand on this.

Forgot to mention that I bought a "Professional Series" LCD and it had no bad pixeles.
