Can my early 2015 MacBook Pro 13" drive a Acer Predator X34P at UW-QHD (3440 x 1440)

I have an early 2015 MacBook Pro 15"
I currently use it with a Dell 29" U2913WM at 2560 x 1080 @ 60 Hz
It works great, even if I also use the Macbook’s 13" screen.

I am thinking of upgrading to an Acer Predator X34P which is a 34" screen that runs at UW-QHD 3440 x 1440

Can the MacBook drive this resolution at 60hz?
I am using the Mac for web browsing, not games

I know from marketing material that it can drive one 4k display, so UW-QHD 3440 x 1440 should be OK??

The real reason to get the monitor is for games on the PC, but since the monitor is so big I can’t fit both monitors on the desk.

Without trying the exact hardware my answer is a :man_shrugging: probably, most likely, buy from someone with a good return policy :wink: or try on a friends if they have a monitor of a similar resolution.

This may be BS on my part, so take it or leave it, but I believe the only issue you would face is not, the machine being unable to get a display out of the monitor, but rather a slight performance degradation from powering the extra display, but that should be negligible.

A 3440 x 1440 resolution is below 4k. So you should be able to drive the (lower resolution) monitor.


Yes, I drive a 4K monitor at 60Hz with mine, but you will probably have to use the Thunderbolt port. The HDMI port on 2015 MBPs can’t handle high resolutions at 60Hz. Just make sure you have one of these Mini DisplayPort to DisplayPort cables around.

Edit: sorry, but I put a link to a Mini DisplayPort to HDMI cable. You can’t use HDMI or you’ll get 30Hz only. Now it’s fixed.

Yes, this is likely true. I believe the HDMI port should only be able to handle up to quad resolutions. I drive a 25" 2560 x 1440 from the HDMI on my 2013 MBP.
