New X800 XT PE - Defective CRT Pixels

Alright, I know this is a total noobish thing to ask...

But it is possible for a video card (in this case an XT PE) to cause
defective pixels to appear on a CRT? I've been using it for 7 days, but over
the last 2, four little red pixels have appeared on my screen within inches
of each other. Is this really just coincidence?

It's almost impossible to have dead pixels on a CRT. Very impossible to have
stuck (red in your case) pixels on a CRT. That means that either you mean
LCD, or your videocard/driver is bad.

But first clean the screen--I've occasionally had crud on the glass that
looks very much like stuck pixels.

A Cathode Ray Tube (CRT) can't develop dead, white or "on" pixels. So I'm
assuming you meant to write LCD/TFT. And no, a new video card can't cause
pixels to fault or die. If this is what's happening, it's the actual monitor
itself that's at fault. I've read numerous consumer reviews and complaints
where their new LCD/TFT screen developed pixel faults over the first few
days of operation. These days, with low cost, high volume LCD/TFT monitors
becoming the norm, quality control suffers. "Good" brands suffer these
faults as well as budget ones. We recently bought 10 Dell 17" E173FP 16ms
displays at $249 each. They've been on 24/7 for a couple months, and none so
far has a dead pixel or live one. Two friends bought high dollar, high
performance 12ms flat screens (Samsung Syncmaster 710T and a NEC Accusync
LCD71V) and one had two dead pixels out of the box. The other was fine when
turned on, but over a week developed one white pixel and one dead. The "on"
white pixel was covered by warranty for and is being RMA'd, but 2 dead ones
on the other is not enough for warranty replacement.

If you are correct with your monitor type, and the glass on your screen is
clean, could this be a symptom of the card getting too hot....?

The monitor is a 22" Sony Trinitron CRT. Definitely not a TFT :o)

The red pixels are actually tiny, so I could live the few that are there
now. I'm just worried that there appearance has pretty much coincided with
the upgrade from an 9700Pro to the XT. If more start to appear then, I'll
have to find out if it's just a defective monitor or if something else is
the cuase.

If you use DVI, you can get some pixel error from the cable you're using and
can also depend on the video card and resolution. I did, until I bought a
quality DVI cable. Cost me $40, but it took care of the issue. I have a
nVidia in one PC and that looked worse than my ATI, but my ATI showed an
issue too.
 
Best of luck to you.
The reason that I mentioned the graphics card as the possible cause is that
I have read of dots appearing on the screen, either within games or the
desktop, when it has been related to heat or a faulty graphics card, rather
than the monitor.
Easy enough though to elimate either as the cause if you have another PC to
swap things over with.

What he's describing does not sound like Artifacting, like one might get
from OC'ing a vid card core/memory. Artifacts are rarely if ever stagnant
(in just one specific spot) they are random specs or a totally corrupt
screen in some cases. I honestly have never heard of a crt with stuck pixels
tho, LCD's sure as each pixel turns on off and could get stuck but not on a
CRT since it shoots a beam to the screen surface so theres nothing to turn
on/off. Prolly should at least call the Monitor manufacturer and touch base
with em. Maybe there was some defect in production or something. One thing,
can you go to say a dos windowset the background color to say white or blue
and go full screen. Are the specks still there?
 
Easy enough to try your old video card and see if the red pixels remain.

The refresh rate you are running is within the capabilities of the monitor,
right? Doesn't hurt to double-check.

It is not your monitor. It is physically impossible for it to be your
monitor if its a CRT.

I can clearly see they're individual pixels when looking up close.

They also remains stationary when trying the following:.

1. Resolution change
2. Refresh rate change
3. Using DVI-to-VGA adapter
4. Degaussing
5. Altering screen geometry e.g. pincusion, move-down, left-right etc.

It will be video card if the dead pixels move when you adjust the screen
positioning with the MONITORS controls.

It's dirt on the monitor if the pixels are stationary when moving the video
positioning.
 
yes is possible but its not stuck pixels its a trinitron tube
whats happend is sum crud has been thown into the wire shadowmask by high
voltage in the crt
this can happen if its been moved and lay on its face
you could try laying it on its back (screen up) and tapping the glass with
soft plastic hammer (care-full like) that might dislodge it
 
Thanks for the suggestion Keith, but no luck. They are absolutely tiny
though, so I could probably live with it. Even though its under warranty,
I've had shit luck with monitors and I'll prolly get a replacement with poor
geometry or something :o)
