Is it possible to record 720p on older LCD?

Hello, I've been using a Samsung SyncMaster 205BW for ten years now and it's still going strong, but it can only display the following resolutions (see the attached photo). Do I have any chances to do a video recording of my desktop and have it at least in 720p?

I'm using a screen resolution of 1280x960 right now, and most of the video capturing software (for example Vokoscreen or SimpleScreenRecorder take this resolution as the default recording resolution). Unfortunately, that's not 720p.

Any suggestions appreciated. Thank you.

Re: Is it possible to record 720p on older LCD?

it depends on your gpu hardware as well as to what output is available. if your overall system is powerful enough you could do the recording in a virtual machine set to 1280x720.

Re: Is it possible to record 720p on older LCD?

I have a HP Probook 4540s notebook, i5 CPU, 8GB RAM, 256SSD, and Intel HD3000 graphics.
The problem is that I can't set the resolution to 1280x720. Do you think a virtual machine allows me to do that? Or maybe there's a way to shot at 1280x960 and reduce it to 1280x720 without loss in quality. I tried using blender to re-encode the video and force a 720p output but things look a bit stretched after re-enconding 1280x960 to 1280x720, not ultra stretched, but it's noticable.

yes do it in VM. e.g. VirtualBox with guest additions allows me to take screenshots at 1920x1080 while using a 1280x1024 monitor.

You can use either FFMPEG or gstreamer to record your desktop in any resolution you want. To me, using FFMPEG is the easiest - quite trivial actually - a real one liner:
https://trac.ffmpeg.org/wiki/Capture/Desktop

It is a prime example of where fancy GUIs and wrapper scripts make a simple operation more difficult.

Thanks, the problem with FFMPEG is that when I set the resolution to 1920x720 it crops the screen.
I want to record 1920x720 16:9 on a 4:3 screen.

I'm not sure how much a widescreen monitor is off ebay where you are, but you could pickup a 720p one for ~£20-40 in the UK... if you specifically want to record in that resolution you may as well natively work in that resolution considering the price.

Woah, stop before spending money...

You could install the X dummy driver and then set the resolution to anything you want with xrandr.

https://xpra.org/trac/wiki/Xdummy

Some googling will quickly find you guidance on this.

But he's running a monitor that can't even even display 720p... and he could upgrade for pennies...
