I started up the game, the video clip size is small.
and the noise of the movie takes place.

I tried to control the size but I can not find option.

Please see the attached images..

I kind of found a solution to this. I switched my monitor's display WIDE MODE to FULL (might be called something different on your monitor, press your monitor settings buttons and see what options are given to you), and the game no longer showed up as a small window in the center of my screen.

This is just a guess, but I think some games that are low res are actually being shown at that low res within your regular computer monitor resolution, or possibly just within your monitor's native resolution. So by switching your WIDE MODE to FULL, the game scales the source maybe?

I don't know, it worked for me.
