How Can I Fix Long Monitor Startup Delay

I've resolved a few monitor slow to wake-up upon boot problems, just by booting into the Safe mode.
It's a driver thing. It may not resolve your problem, but never discount the Safe mode. :)

have no idea if this is related, i doubt it. But my computer does also startup by itself. It can be shut off for days and it will still randomly turn itself on sometimes.

I tried entering bios/safe mode but its really hard with no monitor. It didnt work out.
I played with the buttons on my monitor and i get the message if a missing signal between computer and monitor.

I found this solution which i will try tomorrow after i sleep but it is very vague:
"I KNOW THE SOLUTION

REMOVE YOUR POWER CORD AND HOLD THE ON BUTTON FOR LIKE 30second TO A MINUTE AND THEN CONNECT IT BACK AND TURN IT ON" http://en.kioskea.net/forum/affich-3...ter-won-t-boot

What power chord? What button? I will have to try to troubleshoot it.

Still nothing. What is causing my monitor to be stuck in power saver mode until login window?!?!?!?! GUH!

The guy from kioskea thinks you should reset your BIOS. The procedure he describes will only reset the BIOS Settings defaults. You can do this more easily from within the BIOS settings.
I doubt this procedure will affect your problem.

The problem has to do with something in the video card, the video drivers, or the windows video settings. The second monitor (TV) is most likely the initial cause (although this should not be a problem).

I have an old machine with a Radeon 9800 Pro video card that has always had the annoying feature of thinking there are 2 monitors. Did it in XP too. I had that exact same problem with that machine until I discovered what was happening and disabled the phantom monitor in the Windows settings. The machine was delaying startup as it resolved which monitor to initiate. The real monitor would go into power save mode while this happened.

I think you have a similar problem. It will be up to you to search for any clues in your system's settings to find any anomalies. Check in Device Manager for unknown devices (related to video). Check all through the display settings from Windows Control Panel. Check all through the settings in your video card's driver utility (CCC for AMD, or nVidia Control Panel). Do this with both monitors connected and then with the TV disconnected. Look for differences.

You might also try reinstalling or updating your video drivers. This may at the least clear any conflicting settings that occurred over time.

No, not stupid. That was good thinking.

Now it would be interesting to know why that worked. I'm guessing that either Windows or the Video card keeps track of what device is plugged into what port. If that is the case it would be good to know how to clear that or reset it.
