Hello,

Managed to grab myself a Predadtor XB280HK and I'd red before buying 4k2k 60hz which isn't bad at all for me I'm happy with 60fps however I can't get it past 24hz

In bios and during boot it shows 60hz it hits windows and it drops to 24hz both windows and Nvidia show all the resolutions and whatever i pick it's 24hz, replaced the cable with an amazons basic DP 1.2 after reading Nvidia saying 1.2 can hit 4k@60hz and still locked to 24hz.

Tried custom resolution with Nvidia and set to 60hz and black screen no signal. Tried CRU which shows me the monitor can do it but also has a block at 24hz.

Also tried disabling intenal GPU, installing drivers , reseating, reinstalling Nvidia drivers from fresh and nothing....

Plug in a generic LG monitor over HDMI and I get 60hz but this monitor won't push past 24hz.

I've ordered a recommend cable from
DisplayPorts list of cables named starTech which describes running at these resolution and is 21.x GBPS bandwidth as a last resort but am
I missing something else ?

All help is appreciated as I don't want to return the monitor
