LCD, is this really where we're at?
 

Hello

I've been very happy with my old Sony CRT, but (even thought it's still
working fine, and the picture looks good) it might be time for something a
little bigger and HD. I'm looking at 32" at the moment. This'll be primarily
for TV, as there's a projector for decent movies.

I have 4 LCD monitors at home 17" or bigger, 1280x1024 or greater. Of these,
one has a dead pixel (R,G&B), one has a stuck sub-pixel, and one has a whole
column stuck white (this'll be a warranty repair).
At work I have two monitors. One has a dead green sub-pixel.

A colleague recenly bought a 32" LG LCD TV/monitor. It had a stuck red
sub-pixel. This TV was collected by LG, waited in their repair dept for 3
weeks, then was sent back as "beyond repair". It was replaced by the store.
The replacement has a stuck blue and green sub-pixel.

Are there ANY manufacturers that can actually supply a fully functional
panel?!

If you examine a CRT as carefully you'll likely find faults too.

I have four LCD devices and none of them have problems. A Samsung, a
Panasonic and two DGM. I had two Sony as well but they both developed
faults.

Luck of the draw and I've been lucky, I guess. I just bought an Asus 24"
1920x1080 widescreen monitor after reading its user-reviews at Amazon,
deliberately watching for comments about stuck pixels which I didn't find.
I checked it for stuck pixels at the Dead Pixels Test website and found
none. It's an excellent test, with pixel-level checkerboards that show up
the tiniest speck of dirt, and I found that all "flaws" just brushed off.

I did find that I didn't like the fine pixel resolution compared to my old
15" 1024x768 laptop because it made pictures on most web pages look too
small to my eyes and it was no good zooming them because that blurred them
-- and I hated that this huge monitor had no more height that my old
laptop and that the extra width was no help for web pages which I only
then realized were largely optimised for a 1024 pixel width monitor. So I
sent it back and got a Iiyama 19" 1280x1024 5:4 ratio monitor and found
that to be just great -- and no dead pixels.

If you don't need to change your TV straight away it would be a good
idea to wait a few months when Freeview HD sets will be available.

They didn't work too well for me. I have a known fixed pixel (bright green),
but those patterns rendered it almost invisible. I could just about make it
out because I knew where to look.

Perhaps just a plain background would have been better.

If you are considering a new TV then look closely at Panasonic
followed by the new Sony's. Samsung (especially) and LG are good
but are considerably over-hyped.

Well, yes. To be fair, it is a "dead pixel test" which arguably just
means unlit pixels. An always-on pixel is easy to find on a black screen.

Best thing where possible is to check with the manufacturer (or indeed the
shop you're buying from) to ask what the specific policy is with regard to
dead pixels for the screen that takes your fancy _before_ you buy and try
and get it in writing as sadly you never know what's in the box with LCD's
until you get them out and see the horror of the LCD monitor test
application :)

I have tried this. All responses to date indicate that dead/stuck pixels are
allowed. The only thing you can do is keep swapping the device (gets
expensive in postage if it's from an online source) until you get a
satisfactory unit. And even that won't guarantee that there won't be deaduns
in a few years.

Well, sadly, I did do this for our TV! No defect found.
However, I have a 17" Mitsubishi CRT monitor that has dirt on the shadow
mask. Looks a bit like a dead pixel.
