Can I get 4K @ 60Hz?

Jaaay · 10 Dec 2017 at 11:36

Hi guys,

Currently running a 40" UHD TV off my 2015 13" Macbook Pro Retina, but I can only get 4K @ 30Hz, and this is over HDMI.

I have a Thunderbolt to HDMI adaptor which I have used for other displays, but using that I can only get 1080p

Looking on Amazon, I can only find similar adaptors that max out at 4K @ 30Hz (which is what I'm getting using a HDMI cable anyway)

So I'm wondering if 4K @ 60 is actually possible, and if someone has a verified adaptor they can recommend?

Thanks

Seems your model can support 4K@60hz via display port ( doubt the dp to hdmi will work tbh ) .

Have you got USB-c? Apple states 4K 60Hz is available when using a USB-c to HDMI 2.0 adapter and a HDMI 2.0 cable.

Yeah, the apple specs page says it can do it, its just finding the correct thunderbolt to hdmi adaptor that will work.

No its the 2015 model, so I've got 2x Thunderbolt 2 and 1x HDMI.

Looks like I may be out of luck here

Club3d do an 'active' adaptor that's meant to run at 60hz

I have the Club3D adapter and can confirm it works. I have a 40” 4K TV plugged into my MacBook Pro retina 15” late 2013. I get 4K @ 60hz

Reason you can’t get more than 30hz through the HDMI is because it’s HDMI 1.4 which doesn’t do 60hz at 4K.

Hopefully this helps!
