60 fps with MacBook Pro 13" 2015 & Samsung JU6445

Hello all,

I'm despairing (because I have spent hours languishing on this particular issue with no progress) and am in need of your help.

I have recently bought a 13" 2015 MacBook Pro (256 Gb version)

&

A 48" Samsung JU6445 (6 Series).

This Apple support article says that I can run 60 fps: Use 4K displays and Ultra HD TVs with your Mac - Apple Support

I bought the TV from Currys in Bradford, UK, and their website says that this particular model of TV has 4 HDMI 2.0 inputs: http://www.currys.co.uk/gbuk/tv-and-home-entertainment/televisions/televisions/s amsung-ue48ju6445-smart-ultra-hd-4k-48-l…

I thought that the problem might be the HDMI cable I'm using, but from what I've read, all HDMI cables are either 'standard' or 'high-speed' and the 'standard' cables can't support 3840x2160, which leads me to believe that all the cables I have are 'high-speed' as I'm getting 3840x2160 on this Samsung TV with all of the cables I have.

The problem is that I'm getting 30 FPS, not 60 FPS. This is laggy and not what I want/need.

Can anyone tell me why I can't get 60 FPS with this setup? I've failed to work it out.

Many thanks in advance for any light you can shed on this issue.

Kind regards,

Harry

Hi Harry,

I have the same TV connected to my Mac Pro 6 core and am suffering audio lag too.

I've tried HDMI and thunderbolt to hdmi cables and no luck. I have thought about trying the welkin 4k adapter on the apple website but not sure if it will be any improvement.

One thing I have been unable to find is whether th information does support 60hz 4k? The resolution seems to max out at 3840 x 2160.

Its proving a hard nut to crack!

Lee.
