LCD Screen buying advises

It should be running 32-bit colour (not 16).

You must of had some truly wacky cable if it was giving you so much grief. I've been using 3 DP cables for years (Radeon 6990, 7950 [I think]¡ 7970, and 3 different GeForce 780 Tis). Displayport is the best in my opinion (with second place going to dual-link DVI).

I know it should be 32 bit, my custom profile gives me 32 bit but not the native (at 60hz)
Its the cable that came with it
Just tried V-Sync, all seems good, no tearing. Game reports 3440x1440 @ 60
Screenshots. Battlefield 4 looks gorgeous

Well if you're running 32-bit colour, 3440x1440 res, 60Hz, 60fps, all at the same time, then I'd say you're doing just fine. Beautiful monitor you got there

I know this thread is old, punish me as you will.

I just wanted to clarify why your computer is doing that.

Video bandwidth is calculated Horizontal * Vertical * Colour Depth (# of bits) * Refresh rate (in Hz)
You calculate colour depth because it's the number of bits required to generate the colour of each pixel in the frame.

3440x1440 32bit @60hz is 9510912000bps or 9.51Gbps
3440x1440 32bit @50hz is 7925760000bps or 7.92Gbps
3440x1440 16bit @60hz is 4755456000bps or 4.755Gps

HDMI 1.4 is only supposed to handle approx 8.2Gbps of video bandwidth, so your PC should only be letting you chose 16bit@60hz or 32@50hz because it can't support the full bandwidth via HDMI, unless your computer is pushing into the other bandwidth of the cable normally reserved for audio/signaling/ethernet(in the case of HDMI 1.4).

I'm sorry I can't offer a reasonable explanation as to why you displayport cable did not work.
