what are you doing that requires these two pixel columns
record at 1368x768, you will lose 2 columns and result in a 1366x768 resolution
You can't extend the recording dimensions past your actual dimensions
get a really big monitor bigger than 1366x768
buy a monitor with a higher resolution
Does putting it into actual fullscreen fix the problem?
get a second moniter and a capture card. then you can record anything with a moniter or a screen.
get a 1368x768 monitor to compensate for the 2 columns you are losing
1368x768 monitors don't exist...
