Ive recently bought a 4k tv and im still running a gtx 780 which can only output a full 4k signal over its display port output, due to various reasons a substantial upgrade is off the cards at the minute so im looking at an active displayport to hdmi adaptor or a displayport to hdmi cable. Will either of these introduce any latency to the image ? Im not playing any of the latest games neither so im hoping the 780 will manage 4k (half life 2 and the like)
