Select the monitor (not the TV) and then make it your "Primary Display".

See if that does it.
Already is and always will be primary display

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.

Is it F2? I will need to know the exact keystrokes. Or i can just hard boot i suppose so it auto startsup in safemode. Im not sure if it does that anymore, it has been so long!

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:


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.

Well i fixed it. How did i fix it?

I switched the connections on the back of my computer. Monitor is now hooked in where my TV was hooked in and the other way around.

wow. just wow.

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.

i had figured windows or the computer prioritizes each port and the one i now have the monitor plugged into has first priority. Pretty much what you said above. For whatever reason it pays more attention to it.

My computer is doing the same thing, but I have only the monitor that shipped with it plugged in. I've tried resetting the BIOS through the power drain, removing my ATI Radeon card, and it still happens. I've tried updating the BIOS and drivers, but will try the video driver again just to be sure. So far, nothing has made any difference. I've left the computer on after powering up for hours before the monitor finally turned on to have me log on to windows.

I'm hoping someone has figured out a fix to this problem and can share it.
