I'm trying from another port! There is a thin horizontal line about 1/4 way up from the bottom of the screen on my high resolution Apple RGB monitor. It's always there even against my desktop pattern. Is this a defect and should I do anything about it. I've only had the monitor about a month. Any ideas? HDM (hmayor@bcm.tmc.edu)

The thin line is a shadow caused by a wire used to position the screen. It occurs on all Apple RGB monitors (in fact, I'm typing on it right now :-). So, it's not a defect.

Probably a dozen postings are on the way... but the line is a wire inside your color monitor. The bigger the monitor, the more wires it has. Don't worry about it, it's normal, and there's nothing you can do. If it's any consolation, after a few months, you never notice it... +--------------------------+-------------------------------------------+ | Stephen Fleming | In ten years, computers will just be | | fleming@cup.portal.com | bumps in cables. --Gordon Bell | | CI$: 76354,3176 +-------------------------------------------| | BIX: srfleming | My employers may disagree vehemently. | +--------------------------+-------------------------------------------+

Thanks for all the great replies I got about my HighRes monitor. YES when I look closely I can see it on my trinitron TV too. I'll consider it a neat birthmark! Heather Mayor

All Sony Trinitron monitors that I have ever seen have (at least) two such "defect" lines, usually about 1/4 and 3/4 of the way down the screen. I don't know, but I've been told that this is a result of the manufacturing process. An alternative explanation that I've heard is that these lines are thin conductive strips which prevent static buildup on the screen. I am new to Mac hardware and don't know if the hi-res Mac monitor you mentioned is a Trinitron or not. I have a 16" Sony Trinitron (for my RasterOPs 224) which exhibits these thin horizontal lines. They are thin enough that I barely notice them. I sometimes shoot slides directly off the screen and the lines don't seem to show up. ~chuck -- +--------------------+ Chuck Ocheret, Sr. Staff Engineer +---------------+ |chuck@APT.Morgan.COM| Morgan Stanley & Co., Inc. |(212) 703-4474 | | Duty now ... |19th Floor, 1251 Avenue of the Americas|for the future.| +--------------------+ New York, N.Y. 10020 USA +---------------+

I originally saw these lines several years ago when I bought my first Trinitron monitor. I thought I had a scratched CRT. I saw that other Trinitron monitors had that line too - in the same place - so I didn't think about it. Doesn't look like a manufacturing defect, though - it's nice and straight, almost as though it was intentionally put there.

Any ideas? >HDM (hmayor@bcm.tmc.edu) All Sony Trinitron monitors have a thin wire across the shadow mask (they call it the slot grid). This wire helps keep the tension on the metal rungs as they dissipate heat from the electron guns, which prevents them from distorting. If they didn't have it, you'd see unpure colors, varying as the image changed. You can see this thin wire if you look hard enough at any Trinitron, Apple's or otherwise. Other picture-tube designs do not need a wire, but then again they do not always perform as well as the Trinitron. It is a trade-off, and a inconspicous one at that. Look at someone else's Mac, or go to the dealer you bought it from. The demo's have the same thing.
