Windows 7: Trying to Use My HDTV as a Primary Monitor

Trying to Use My HDTV as a Primary Monitor

I set up my computer with my HDTV on the raised platform in my living room. I have the HDTV connected to my graphics card via HDMI cable. When I start my HP computer the HP splash screen comes up and then the screen turns black and I do not get the Windows 7 login screen. However my grpahics card has an additional port (DVI) and If I connect a monitor to the computer in addition tot he HDTV and start the computer I get the HP splash screen on the monitor and then eventually the Windows 7 login screen will come up on the HDTV.

If I then discconect the monitor and leave the HDTV as the primary display and turn off the computer and reboot the same thing happens where I get the HP splash screen and then goes black. Can anyone tell me how I can just get the computer to recognize the HDTV as the primary display and the windows 7 login screen to come up on teh HDTV? Thanks for any help that I may be given!

When you hook both the monitor and the TV up to the computer, go into the display settings and look at what the computer is recognizing as the main display. If it recognizes the monitor as the main display, you can just change the settings to the TV as the main. This should solve your issue when you unplug the monitor

Already did that

Thank you for the suggestion I have tried exactly what you have suggested and I have indicated my SONY HDTV as the primary device and upon restarting the screen displays the HP splash page and then goes black and the only way I can get the Windows 7 login screen to come back up is to restart the mahince with a monitor hooked up.

Is there a way you can have them both hooked up, set the HDTV as the primary, then remove the monitor from your settings so that the TV is the only display? Then apply the settings, save it, and reboot to see if it will boot properly?

Does the Sony have the 15 pin VGA connection on it? If it does you might want to visit your Sony manual to see if this is the PC input Sony designates. If that is the case you can get a DVI to VGA converter and pick up a 15 pin to 15 pin monitor cable or go the other way and convert the Sony 15 pin to DVI and use the DVI cable. Your HDMI can be used for audio or if you have a TOC fiber output on the Sony and your Sound Card I'd go that route, my 37" Vizio uses what I just explained w/o issues.
