Can this monitor be mounted on an Ergo Arm? And in some reviews I saw screen tearing like in this video kzbin.info/www/bejne/ZpyTY3qNqcZsY7M one can clearly see screen tearing (First Few Parts of the video ) so can you overclock the screen refresh rate of this monitor to 75 or 80 Hz and check if there's any screen tearing or not with G-Sync Enabled?
