Anyone have this weird thing in their Trinitron monitors?

[sho.gun]

My friend just bought a monitor with the Trinitron tube, flat screen. He noticed that there are 2 faint horizontal lines running through his monitor so then he exchanged it for another. His new one is also has it though. So then right now I'm in comp class and they have the Dell flat screen monitors with trinitron and they also have 2 horizontal lines going across. I checked all the other monitors in the room and sure enough they have the lines. Are they supposed to be there? Kinda bugs me after a while.

the bigger the more you need 15 TRIns have one 17-24have 2, I have read larger would theroetically need more, Thats how it is flat on the screen not curved

Yeah some people are bothered by the faint lines Trinitron and Diamondtron tubes have. Personally, I don't even noticed the 2 faint lines on my Diamondtron monitor.

Q. I have just noticed a thin gray line on the image displayed by my Sony computer monitor. It is about one-third of the way from the bottom of the screen. Is this normal?

(A) This is normal. What you are seeing is the shadow cast by the horizontal damper wire used to stabilize the aperture grille featured on all Sony Trinitron picture tubes.

trinitron = diamondtron = XXXXtron

they all use sony's technology..
sony had a patent on it, so i think they all have to pay sony royalty fees for using that technology...

and yeah, it's the whole aperture grill vs shadowmask thing..
to really explain (geez forgot some of this stuffs)
Shadow mask uses a metal screen with holes in it so that the RGB guns fire through the wholes and it the phosphor layer (phosphor burns, if u ever heard of that).
Aperture grill uses vertical wires, and so the pixels of the phosphor are striles instead of the holes. This is supposed to make the images brighter (can't remember why :() and the vertical resolution (like when u see specs on monitors where the vertical dotpitch differes a lot from horizontal dot pitch) can be really good...
but u need the 2 horizontal wires to hold the vertical ones together...
and yeah, you only need one when the screen is 14" or less...


but this kinda cracks me up, he actually returned it, and the computer people there actually accepted the return because of 'lines' HA HA HA :)
What computer store, so that we know which company hires clueless people :)

i have it too on my trinitron. don't let it bother you, you won't even notice it after a little while.

Everyone with a Trinitron has this. Like att gig said, it is truly a sign of a clueless store staff to not know this. I have know some people who are heavily into CAD work that couldn't tolerate the lines.

[clutchy]

man, i thought everyone knew about this already, i guess not. There's actually 3 tubes in there and it's kindof a false flat technology i guess, but those lines are the dividers between the 3 tubes.

personally i really dig on samsung's dynaflat tech no lines and great color and pic.

[brainsmile]

yeah I've got that too.... used to bug me... now I hardly notice it

[joe52985]

lines are just there to hold up the aperature grill (dont laugh if im wrong on wording here) or whatever it is, i think they add character :) but on another note i have very weird trinitron monitor, my dell p991 uses sony tube, and vertically there arnt lines but there are faint faint faint bars of diff collors, like ligter than the backround, milimeters apart, is it just my monitor, i also notice some crawling at the edge of windows and the edge of the screen, anyone have similar symptoms?

[yippiekiyeh]

Yup... wires are normal for trinitron and diamontron monitors...

[BustNuts37]

Yup.. I got those too, only two though.. Is this only for 20" monitors??

[Jeffbx]

All trinitrons have them.
