Forcing custom resolution in windows 7 without a monitor (connecting via Teamviewer)

I have a computer that I control using teamviewer only. When I connect to the computer, the resolution is 640x480. I tried changing the registry values of DefautlSettings.XResolution and DefautlSettings.YResolution, and I tried disabling the TMM. Nothing helped.

The computer has R9 290x GPU.

How can I change the resolution?

Thanks for your help,

If your host display adapter allows you to add custom resolutions, you can set one up and use it in teamviewer settings when connecting to that computer.

I have Nvidia GF 9300 M and my laptop display only allows up to 1280 x 800. I defined a 1440 x 900 custom resolution. That's how I overcame this issue when I connect to my laptop from my desktop.
