Numbers too small to see in game.

All the numbers on the UI are too small to see. I know what causes the problem. Apparently it's because I use an HDMI cable to hook up to a TV as a monitor, but RITO won't fix it cause not many people do that and have my problem.

I can't see my gold, I can't see my name or other peoples names, I can't see my level or other peoples levels, I can't see my CS, I can't see # of dragons, I can't see how much gold I get when I kill something, I can't see my damage, I can't see the teams score, I can't see my score or other peoples scores... All I see is what looks like a small dot in place of what should be a number, and a small white line where a name should be...

Even when I press Tab, I can't see anything. It's impossible to try and win when I can't see those numbers.

Last patch, before the new UI, I could see all the numbers and names, except on peoples health bars overtop of their characters. Their level and name was too small to read, monsters HP numbers were too small to read, and the gold achieved from killing an enemy was too small to see. I could see everything else though, so it wasn't a big deal.

But now, it's unplayable. It's not fun to play when I literally can't see any numbers.

How hard can it be to fix... WoW doesn't have this problem.
