Changing screen resolution from 1080p to 720p?

[Yesirom]

I'd like to record some video tutorials in 720p because it's more practical, mostly because of the file size but my screen size is 1080p.

I'm using an ATI Radeon 2600 XT graphics card and I can easily change the screen resolution via Catalyst or just using the built in Monitors feature in Ubuntu.

The only problem is when I change the resolution to 1280x720 part of the screen gets clipped. Something like this http://i.imgur.com/UET9o.png

Is it even possible to make it go fullscreen?

Test what screen resolutions that work using

xrandr

Without parameters it will tell which resolutions that are displayed properly by your system. Maybe 1280x720 is not, so select another resolution. See the manual how to run xrandr with options

man xrandr

I tested other resolutions from the dropdown that worked and it was great but the only problem is that those put black bars on both sides. I'll try this method out, stay tuned

My system can display 960x540, which is exactly 1/4 of 1920x1080, so I get not black bars. Does it work for you?

I don't have that option

I don't have black bars when recording but when I upload the video to YouTube or Vimeo it adds those black bars because it expects 1280x720 (at least I think so, why else would they add it?).

But 1280x720 is listed Maybe you can adjust your monitor (manually with some buttons on the edge of the monitor screen), to get the screen fit the video output.

Here is the output for xrandr:

I'm not sure what to do now, what is the difference between changing the resolution with xrandr and using something like catalyst or monitors?
