另外官網論壇GTX980/970戰4K電視的問題一大堆...
GTX 980 and Samsung 4K TV (HU8550), 60Hz works but not getting 4:4:4 (Full RGB) output
GTX 970/980 owners: Are you getting full colour at 4K/60Hz via HDMI?
GTX 980 - Can't get 4k at 60p on Samsung TV
GTX 980 & 4k Samsung UN50HU6950 troubles
New Samsung Update fixes 4:4:4 4k 60hz
LG owners: your TVs are NOT doing 4:4:4 at 4K/60Hz

難道問題其實是在NV的HDMI 2.0?
