Lenovo ThinkVision X1 display and MacBook (retina)

Today I took delivery of a new Lenovo ThinkVision X1 display. I specifically chose this display for my MacBook because it support USB-C; finally I can get rid of the Apple USB-C dongle and run everything from a single cable as nature intended. However, while the monitor works just fine with an HDMI cable (not 4K of course), I cannot get my Macbook to recognize it when I connect just using the USB-C cable. It does see the USB hub in the monitor, but not the display part. Does anyone have any experience getting this monitor working? I've tried both Apple USB-C that came with the Macbook as well as the USB-C cable shipped by Lenovo.

Thanks

And with my third usb-c cable, I have it working.

And with my third usb-c cable, I have it working.

A little more investigating, and it looks like it's related to the length of the USB-C cable; the short one works, the long ones don't.

Hello aanon4,

I also intend to acquire this monitor.

How long (short) is the USB-C cable which works ?

Which third part USB-C cable is it ?

Does the monitor charges the MacBook ?

Does the display works at 60 Hz ?

Thanks in advance for your answers

Regards

Can you tell me which cable ended up working (brand, length)? Thank you.

It's a 3 ft long cable from monoprice - https://www.monoprice.com/product?c_id=103&cp_id=10303&cs_id=1030319&p_id=13003&s eq=1&format=2

The monitor does charge the MacBook which is essentially really. However, it will not run the monitor at 60Hz in 4K (only 30Hz which is painful), only in 1080p/60Hz. Interestingly if I use a different Mac on this monitor, it will only run the monitor at 4K/60Hz using a Display Port cable, but with HDMI it is limited to 30Hz at 4K. If I dual boot the same hardware into Windows 10, it'll happily run the monitor at 4K/60Hz over HDMI and DP. Not sure what this tells me but I thought it interesting.

It's also worth nothing that it all seems a little buggy. For example, if you have two computers plugged in - one on USB-C and another on DisplayPort - you can switch between the two quite easily. However, if you unplug the one currently selected you *cannot* switch to the other input sources; nor does it auto-detect and switch itself. Turning the monitor on and off doesn't appear to help either. A bit annoying.

aanon4 are you happy with this monitor? i was thinking about getting this but after i found you posts i was leaning more towards a WQHD from LG

I'm very happy with the monitor and am accepting of its bugs - it's my first 4K screen so quite the step up for me. If you're only using it on a single input then the bugs are pretty minor. Even using it for two computers, as I do, the bugs are at worst minor annoyances. I still hope Lenovo issues an update for it at some point.

I just bought the new MacBook 12 inch (2016 version) and the X1 monitor. I can confirm everything aanon4 said (short USB-C cable required, only 30Hz in 4K when connecting the MacBook to the monitor with USB-C, and the bugs when switching sources). As aanon4, I will also keep the monitor despite these annoyances.

The display quality is in my opinion not as good as the one of the Thunderbolt display, but the higher pixel density of the X1 makes more than up for it.

Still, I am hesitant to really recommend the X1. I have not checked, but maybe it is better to buy a different 4K IPS monitor and an additional USB-C to HDMI converter together with an additional USB-C power supply.

Hey, use the patch to make 4K@60Hz available.

From https://v2ex.com/t/277410

Just tried it and the display is now working at 4K@60Hz on my MacBook! Any idea why this isn't a normal option?

Do the USB ports on the display work properly when the Macbook is running at 60Hz?

You only have USB2 of course, but that's to be expected. And yes, they work.

Hi,

short followup question: Does the camera and mic work OK?

Thanks,
