Either a pair of DP 1.2s or a heavily overclocked dual-link DVI. DP 1.3/1.4 hardware still hasn't reached maturity, sadly.
Like many times on wikipedia, this just because NVIDIA and AMD claimed they support DP 1.4Wikipedia says that both NVIDIA and AMD have cards on sale with DP 1.4.
Its not that hard to increase clock speed if you have capable output stage on your GPU.If i remember correctly, DP 1.2 was available on VGA long before DP monitors reached the market. cable length is a DP limitation, and DP 1.4 did not helped it at all. but i am not brave enough to claim that "you won't get DP 1.4 with current VGAs".
No idea what 1.3 would add when you just single handedly invented 4k 120hz on a seiki!!!
I'm kind of confused, this is a thread for the 50" Seki. Is this new board for the 50"?
Do I release now with dp1.2 and offer dp1.3 in the future? It might take some months for that.
