I built a Brand new computer and bought all the things for it to run games on ultra graphics. It worked great for a while!I plugged it into the tv to show my bros what I have done on a game and the game lagged out completely. And now whenever I play on my monitor, it lags out and games only work on low quality! I also Updated my computer on that day and I don't know if that is an issue or not!
Please respond as quick as possible
Thanks
