I've been using my laptop for months now, connected to my HDTV as a monitor via VGA cable, and it's been great. But as it's stuck with the crappy built-in graphics, I decided to switch to using my desktop PC to play games like Skyrim.

 

But for some reason, the desktop PC won't display on my TV. I use the exact same display settings as I used on the laptop(as well as trying others), but after the welcome screen all I get is a black screen with "Please change your computer screen's resolution". If I boot up in safe mode, it displays fine, if I go back to my old tiny monitor it displays fine, and if I go back to the laptop, it displays that fine. I'm not understanding why it's not displaying only in normal mode on my desktop. Is there somethign I'm missing, or am I required to utilize a second display of some sort just to set up my PC to display on my tv?

 

I'm running on Windows 7 Home Premium 64-bit, and my processor is AMD A6-3620 APU with Radeon HD Graphics 2.20 GHz. The HDTV is a Hisense not sure the model but I was able to run the laptop just fine.

You say 'HDTV' - this is a very broad church !  Different manufacturers have very different interpretations of what is HDTV.

 

The only things I can suggest are to check the TV manual - if you don't have a paper copy you should be able to download one - and see what it claims its screen resolution is, then set your desktop graphics to that setting.

 

The other possibility is the physical connection you are using. You say you connected the laptop via VGA. That should still work if that is what you have on the desktop, but, if you have an HDMI output, have you tried that ?

I ran into the same problem when I hooked a desktop to an HDTV.  It would not let you exceed the monitors resolution of 1440 by 900.  A plugin video card that would do 1920 by 1080 was installed and the problem remained, the display was the limiting factor.  Using a monitor that would run1080   and back to the on-board video and the problem was solved.   The monitor was the cause for confusion and the limiting factor.
