Back from my brief vacation in Puerto Vallarta, I return to find my Viewsonic monitor has been returned from warranty repair.
Kudos to Viewsonic as it was long out of warranty. I had contacted them after discovering that the DVI port wasn't working properly, and that the screen seemed to drift out of alignment after a random amount of time (making it unusable) and had gotten an RMA number.
What with moving about and putting things in storage, it was a year later when I finally got it out of storage, stripped it off mount, and sent it out with a plaintive letter asking for warranty repair.
No questions asked, and 20 days later it is returned - actually, as far as I can tell, it's a new or refurbished unit. I had a small scratch on the screen that is no longer there.
Well, the unit manifested exactly the same problem with the drifting out of phase. Hmm.. says me. That makes no sense if they really have replaced the unit.
Then the lightbulb came on. I had used the same VGA cable it originally came with to hook it up. What if the cable is bad (never happened in 25 years for me but there is always a first)?
Lo and behold, it's been running for several days now and no problems! I haven't tested the DVI port yet (though I expect it to work fine).
So a victory for scientific method (and thanks again to Robert Pirsig)..
