I have a Windows 7 PC with TeamViewer installed on it. This computer is always on and has no screen, keyboard and mouse attached to it, only an internet-cable.

I login from my Mac on TeamViewer, create a connection to my Windows 7 PC and the result is an 640x480 screen. The problem is that my Windows 7 PC does not detect any display.

If I check display settings in Win 7 then this happens: enter image description here

I can't select another resolution. How can I choose another resolution?

Did you install the correct graphics drivers? –  ChrisN Jan 10 '13 at 0:04
    
Default drivers of my graphic card are installed. I didn't install any other one. Do I have to? This is my view of Win7 in Teamviewer right now: cl.ly/image/01160D31472I –  Pieter Jan 10 '13 at 0:55

Can you force the resolution using your graphics card drivers? In my nVidia Control Center, I can go to Display-->Change resolution, click on Customize, and click Create Custom Resolution... I don't know if that would work because you don't have any physical displays attached. Your best bet would probably to use Remote desktop - it isn't affected by display size on the remote computer - it uses your local display size. –  ChrisN Jan 10 '13 at 1:28
    
Hi Chris, thanks for your reply. I did try an custom resolution setting but indeed it do not work without a display. So I installed Remote Desktop and now it works fine! –  Pieter Jan 11 '13 at 12:10
    
Same problem with two Windows 7 machines with latest nvidia drivers (2560*1440 host and 1920*1080 remote). But via Teamviewer the remote machine has only Analog display with 640*480 resol –  user187423 Jan 12 '13 at 11:22

@ChrisN comment is the right answer. I'll post it as an answer to the readers:

In my nVidia Control Center, I can go to Display-->Change resolution, click on Customize, and click Create Custom Resolution: Creating custom resolution

After that, select the checkbox that adds it to the list of resolutions and select in on the main "Change resolution" screen.

Try this :

  1. Access Control Panel -> Appearance and Personalization -> Display -> Screen Resolution -> Advanced button.
  2. In the Adapter tab click List All Modes.
  3. If not enough modes are shown, try to uncheck the Hide modes that this monitor cannot display checkbox in the Monitor tab.
  4. Click on a resolution to choose it
  5. Click OK twice.
