could i, if needed turn the asus rog pg278q 1440p down to 1080p on demanding games
I'm also planning to get the ROG Swift 1440p. I own a GTX690.
I have a suggestion for you. If you're playing fast paced shooters like BF4, COD, etc...
Just turn down anti-aliasing and play the shooters games in medium/high settings for Multiplayer.
For Campaign games, go ahead and turn up the settings to Ultra, you should still get 40-60 FPS on Ultra, which should be playable because of G-sync.
Personally, I prefer high frames rather than eye candy for shooters. The high refresh rates + high FPS is a big competitive advantage in multiplayer.
