its for a internet cafe competition solution, host pc needs to duplicating feed to multiple big screens. hdmi/ vga splitter has compression / signal degradation and latency issue, im thinking about quadro nvs cards.

 

the setup is like this, gtx1080(or vega64), outputting 1440p 144hz signal (hdmi/dp), and using quadro nvs to duplicate this signal to 4 or 5 big screens. this is the player pc, so its necessary to keep the performance hit minimum. they are using freesync monitors but gsync is also available.

why everybody post the spec of their rig here? i dont! cuz its made of mashed potatoes!

There won't be any degradation output through another card.

Are you expecting to output a game to another card? if yes, then it is not possible.

some game can, some cannot.

but i wanna do is duplicate the feed from the main monitor(comes from 1080/vega 64) and send them to big screens.

thx for reply anyway.

 

i can get some 2nd hand quadro nvs cards with mini dp out, they are plentful and dirt cheap, ~15 usd a piece. way cheaper than some decent hdmi splitter.

you have to know, long wires can degrade the signal too.

you may also need an active hdmi spitter with build in signal amplifier, the ones with an adapter.

i think we can make them under 10m. for outputting 1080p 60hz signal that probably wont be an issue.
