3840x2160 @ 30 Hz requires a 297 MHz pixel clock. HDMI originally only supported 165 MHz. You need a card that supports HDMI 1.3 at least. The problem is even though HDMI 1.3 is supposed to support up to 340 MHz, most video cards that supposedly support HDMI 1.3 can't handle that much. Only newer video cards have been able to handle 297 MHz reliably over HDMI. I would recommend a Kepler-based card or a 7000-series AMD card minimum.

The patch requires a 400-series card minimum, but you might not need the patch with HDMI if you enable the extension block and import the hdmi-audio.dat file.

Thank you sir! Looks like I'll be buying a card.
