My laptop has a GTX 960M, which apparently doesn't support HDMI 2.0
The laptop doesn't have a DisplayPort output either.
I was going to buy an external 4K monitor so I can comfortably edit photos and 4K video, but I've read that 4K only makes sense with 60 Hz, which is only supported by HDMI 2.0 or DisplayPort 1.2, that my laptop doesn't have. I understood that it will still work, but only at 30 Hz, which is not so good.
Is 4K at 30 Hz only bad when gaming?
Will I benefit from editing video / photo on an external 4K monitor, but at 30 Hz only? Or will it flicker or the mouse cursor lag etc.?
...I'm now even considering to return this laptop if I can't edit video on an 4K external monitor 🙁
But I guess I still need a powerful laptop to handle 4K source files, but I will have to edit it on a normal Full HD monitor.
