how common are dead pixels on LCD?, good brands?

my grandfather was talking today, and was like "why do you still have that old bulky monitor?" you should get one of those nice LCD monitor..
and I told him that paying upwards $700 for a LCD monitor that would be big enough for me wouldn't be worth it since I was planning on getting a 21" CRT for ~100 on ebay

anyways, later he called me at work and was like "I saw this LCD monitor, I think I am gonna get you one.., you need to pick out one, ur uncle sent me this deal for a 21" samsung for ~$650".., so I guess I am lucking out and am going to get a $600 or so from him..; dual monitor time :) :) :)

I am concerned out dead pixels tho.., cause they drive me crazy and I've been told that no manufacture warraunties cover them..

is there any good brands you can recommend?, I would like to get a viewsonic but they are expensive.., how are samsung's or dells, ect.?

thanx in advanced,
Byan

Go fer...er...go for the Samsung. Excellent quality. The possibility of a dead pixel or two just comes with the technology I'm afraid.

I bought a Cornea 18"er last year, been very happy with it (500:1). They're out of business now, but you can e-bay them pretty cheaply. Got a Balance 19"er a few months ago for under $300. brand new. No dead pixels, and it's great - nice huge display (700:1).

hmmm.., are there any brands that have less occurrences of dead pixels then others?

Hard to say....its basically luck of the draw....

But samsung's have excellent track records.

Also I do believe manufactureres have a 8 and above dead pixel policy when it comes to LCD replacements....could vary from manf. to manf....

Yep, some manufacturer's have a low pixel replacement policy, when i got my Benq i had quite a few that seemed to grow, and i took a picture with a digicam and sent Benq the picture and they said that they has a 5 dead pixel return policy and i qualified for a new monitor, it came about a week later, no dead pixels in this one,:) and i still have 2 and a half years of guarantee left(if anything should go wrong)

I would recommend the Samsung too, nice, quality displays.:)

Apparently the Samsung has a zero dead pixel policy:

You may find that some suppliers will do a dead pixel check on any brand of monitor as well, I know that there's at least one UK supplier does that (for a fee).

that is in korea only..
you got my hopes up there for a second

that would be nice if I could find a supplier that will ship to my area that will do a dead pixel check; well worth a little extra money, I think.., specially on a $600 screen

well.., I can't find an suppliers that will check for dead pixels here in the states...
also, the samsung I was gonna get has a 25ms response time, I completely overlooked it before.. what is a good response time, the viewsonic has a 16ms response time.., I do game, how much will that matter?

You should find this article interesting:

I see many recommend Samsung. I bought Samsung SyncMaster 213T 3 mo ago and I love it. No dead pixels, sharp, refresh rates (albeit said to be too low for gaming) nothing I have noticed or bother my. It's a good brand, I just wish I had two...

well, 25ms means that is will be refreshed 40 times per second.., 40Hz
for the 16ms, it is 62.5Hz..
ussually a refresh rate considerer optimal is ~75Hz...

I am guess the industry changed units so that people wouldn't be driven away with much less values for refresh rate then is considered good on a CRT..
well, IDK.., I think I am going to ask my friend what his response time is.., cause I thought his worked nicely

I had this same hesitation before making the switch to LCD. I hate dead/stuck pixels. So I just spent the extra few bucks on a product replacement from the store. They claim that they will replace the monitor if you are unhappy. I specifically asked them about dead/stuck pixels, and they said even if there is one - if that means I'm unhappy, then I can bring it back and swap with a new one. Mine fortunately did not have any, so I haven't been able to test their warranty.

what store would this be?

I recently bought a Viewsonic VP912b 12ms response time. No dead pixels, very sharp image and works great for gaming. Its not the best in its class but I like it.

You can't compare refresh rates like that, because LCD's work in a completely different way to CRT's. There is no flicker with an LCD monitor, like you get with CRT's, and so the refresh rate is irrelevent. The 25ms response time that you quote is the time it takes for a pixel to change from one state to another, and which affects fast moving images such as games. It has nothing to do with refresh rates.

You can sort of work out the rough equivalent response time of a CRT monitor on the grounds that as the pixels have to be refreshed every x number of times per second, then so the response time must be the same. The formula is T = 1 / F, where T is time in seconds and F is frequency in Hertz. So a CRT monitor at 75 Hz is refreshing every 0.01333 S, or just over every 13mS.

all I did is go the opposite way and change it into Hz.., which is better for me since I have used CRT's at all sorts of refresh rates, including 60hz which when it doesn't flicker, runs perfectly for games..
I have a 17" gateway EV700 (I think that is it) and it runs at a top resolution of 1280 × 1024 at 60hz and it works perfectly like that about ~97%, sometimes its starts flickering so I bring the res down to ~1100 X whatever.., and then it runs fine...; ussually I switch back in 20 min or so..

anyways, 60hz works perfectly for games, but I have no idea how it would look with only 40.., so I am going to ask my friend who has a 17" LCD what his response time is, or rather what his model is cause I doubt he would know what the refresh rate is...; I was playing UT2k4 on his machine and the LCD ran perfect cept for the pixel he has that is always lit red...

Of the five or six LCD monitors I've bought for our office over the years, only one (an otherwise fine Cornea LCD) had a dead pixel. I've read, though, that they are not uncommon. Unfortunately, nearly every manufacturer requires quite a few dead pixels before it will replace the monitor.

I've found Dell, Viewsonic, Sony, and even Envision to be pretty good. Right now, though July 20, 2005, Dell has incredible deals on its 2001FP (20") for as little as $526. I only bought the little bugger 10 days ago for $561. So it goes. But I must admit it lives up to its billing. Darn sharp text and rich colors. Very nice.

I got mine at Circuit City. But unless they've changed policies, many of the other stores carry this no-questions-asked type of replacement extended warranties: Best Buy, CompUSA, etc.

but arent the displays much more expensive at those stores then they would be online at newegg or tigerdirect?
I looked at best buy and they seem to be 50% more there..

I was thinking of ordering one those for my other computer. Still looking! Buying a second LCD isn't any easyer than the 1st one I bought. Good grief. I have it narrowed down to Dell, Viewsonic and Samsung.

Draw one out of a hat? :)

Well I have my "old" 19" Sony CRT on my other system, Its a darned good monitor but next to my LCD its not as good as I thought it was. The LCD once dialed in is so much more pleasing to my eyes. And the extra room on the desktop is a major plus.

I've got it narrowed down to either a samsung 21" ~650 with 25ms or a 20" viewsonic with 16ms... ~600
just got to see what response time my friend has to decide between the two..

Glad you have it narrowed down to a couple of good models, Can you post links so that we can pass judgement upon your choices :)



Liam

Remember DisplayMate for your CRT? Try out Monitors Matter CheckScreen v.1.2 to really tweak out your flat panel display. Very nice results.

Have two 17in LCD's:

1-PLANAR
1-Cornea

Both have no dead ones and both excellent picture quality. I am completely satisfied with both. Both are 400:1...
