The cow is using a VR (virtual reality) headset. So he's not actually looking at the tv, he's looking at the screen that's in his headset. The tv is there probably for people who aren't playing, so they can see what the cow sees (both screen have the same thing, but the headset makes it look/feel like you're there in person). I'm assuming it's up wicked high so the one with the headset doesn't walk into it, since they can't see where they're going
