BT would work if my PC was in range, then the input would be fast, but still the added image latency makes micro adjustments pain since you see them late, still.
Running a DP cable instead of streaming would fix that, but you'd need a converter to transform into HDMI for the TV.
HDMI over long distance doesn't work.
Using 1080 to minimize latency already. Can play lesurely platformers, but even playing arcade racing games like Wreckfest, you just lose all feel for the car since tapping the controller applies the change with too much delay.
Hardwiring would be the only way. That's why I'm gonna build a steam os pc for the living room once it's feasible.
