I've managed 2160p at 30Hz through HDMI. Now I know I cannot get any higher in Hz because of the 300MHz limit in HDMI, but which other cable option would be my best bet to achieve 45Hz? 60Hz? Dual DVI to HDMI? Mini Displayport to HDMI? My 6950 has 1 D-DVI, 1 S-DVI, 1 HDMI, 2 Minidisplayports. Any info would be great!Only HDMI 2.0 and DisplayPort can handle 3840x2160 @ 45-60 Hz. You won't be able to get 45-60 Hz with an adapter. I have achieved 4K at 60Hz with the LG TV, using a HDMI to HDMI cable on a Macbook Pro Retina with a Nvidia 750M in Windows 8 on Bootcamp. So it is possible to pump 60Hz through HDMI 1.4 (the Macbook is not 2.0). If a 750M can output 4K60Hz through HDMI and this guy has achieved 4K at 45Hz on two displays using your tools with a 6990, the question is, would a Minidisplayport to HDMI cable achieve anything higher than 30Hz on a 6950? It has 2 Displayport outputs but my LG only HDMI 2.0 inputs. Would a 6950x2 in Crossfire improve the refresh rate? How do think that guy on the other forum achieved 45Hz, via Displayport to Displayport? |
