I have a fairly old Acer AL2416W that is my secondary display in a 2-display setup with a Quadro FX4800 video card. Yesterday I temporarily installed a Quadro K4200 card and realized that the problem lies with the monitor. (A couple of red herrings made me think video card.)
This is NOT the 2-second-off problem. I have had that happen to both of my monitors in the past when they were still under warranty.
The monitor gets enough signal to wake it up, but looses the signal and goes back to sleep until it has warmed up a half hour later.
I almost forgot this part....When the computer is first turned on, the monitor will fire up and display POST. It even stays on while the Windows starburst is showing. But as soon as Windows shows the full-screen startup background, the monitor shuts back down as described below.
When the computer is first turned on, the Acer logo will display, but then "No Signal" is displayed. (The screen never goes blank.) The monitor then goes to standby as expected. About 1/2-second later, the monitor wakes up again, displays the logo, displays the "no signal", and returns to standby. This will continue for about 1/2-hour until the monitor warms up, and then it works fine for the rest of the day.
I haven't popped the cover yet because I'm still using it every day for business. I first wanted to find out if anyone had any ideas on where I should begin looking. I'm hoping it is something visually obvious, like a cold solder joint or bulging caps.
