Xeppa about tech problems

Can someone explain what is he saying? Im not native english and im having a hard time understanding but i have the same problem where i basicly lag on 1280x960.

admin unplugged hdmi cable and fixed his lag
admins also trolled during tech check where they didn't take note of resolution changes for players
and if u play on 1280x960 the admins are supposed to do some shit to the pc so it wouldn't lag
