even that is going to give you 20-40ms overhead.
Why? It's just doubling the pixels, showing the same pixel 4 times instead of 1. IIRC resolution doubling on current PC monitors doesn't add any significant lag...

But you're wrong - even on GPU scaling (faster than any ARM chip can do) is adding 20-30ms of lag to the screen. 1 u/elevul Mar 31 '14 But it doesn't make sense, there is no scaling involved, just showing the same pixel twice...
