DisplayPort support on Yoga 710-14IKB / Yoga 900S-12ISK?

Hello!

I am trying to find out if native DisplayPort is supported on the following two models:

 

- Yoga 710-14IKB (80V4003LMX)

- Yoga 900S-12ISK (80ML000RMX)

 

I need to drive UHD TVs (4K at 60fps) and various high resolution displays using DisplayPort (HDMI 1.4 only supports 4K at low refresh rates). 

 

It seems to be difficult to find out by looking through the documentation provided by Lenovo. I have come across some info though:

 

Yoga 710-14IKB:

The documentation on

  http://shop.lenovo.com/us/en/laptops/yoga/700-series/yoga-710-14/#80V4000GUS 

under "Ports" states that:

 

"Micro HDMI™"
"DisplayPort™ (combo with HDMI™)"

 

This indeed seems to indicate that DisplayPort is supported, but I cannot find any info on how this works.

 

- Is (native) DisplayPort supported by the Yoga 710?

- If so, what kind of adapter/cable is needed, and where can this be found?

 

Yoga 900S-12ISK:

This machine has an USB-C "USB 3.0 port with Video-out". I have found a Lenovo USB-C to HDMI Adaptor-NA (GX90K37871): 

   https://www.cnet.com/products/lenovo-usb-c-to-hdmi-adapter-external-video-adapter/specs/

but so far I have not seen any USB-C to DisplayPort adapter from Lenovo.

When an USB-C port has video capabilities, it is usually using DisplayPort, "USB Type-C with DisplayPort Alternate Mode" (I have seen reviews of Yoga 900S that this actually is the case for the Yoga 900S.

 

- Is (native) DisplayPort supported by the Yoga 900s?

- If so, what kind of adapter/cable is needed, and where can this be found?

 

It should really be possible to direct these questions directly to Lenovo, but it seems that you need a serial number to get in contact with support?

 

Thanks!

Jorgen

Welcome to the forum. I don't know if this will work with your Y900s but Lenovo does offer a USB-C to DisplayPort Adapter, part number:4X90L66916.

Re: DisplayPort support on Yoga 710-14IKB / Yoga 900S-12ISK?

Hello,

Thanks for the feedback!! This may work! However, under "Hardware Compatibility":

 

  https://support.lenovo.com/no/en/documents/acc100310

 

only two machines are listed: ThinkPad X1 Tablet and ThinkPad 13. So, compatibility is uncertain...

 

Any ideas about the Yoga 710-14IKB?

 

Anyone knows if it is possibly to contact Lenovo about matters like this, pre-sale (hope to avoid buying one of the two machines only to find out that DisplayPort is a no-go)?

Re: DisplayPort support on Yoga 710-14IKB / Yoga 900S-12ISK?

Hello again,

 

Yoga 710-14IKB:

I have still not been able to get an answer to these questions. I have been in contact with the Lenovo service partner here is Oslo (I "borrowed" a serial number from a cooperating shop), but they have yet to figure out what Lenovo actually means with the following statement under "Ports" in the documentation for Yoga 710-14IKB:

 

- "Micro HDMI™"
- "DisplayPort™ (combo with HDMI™)"

 

The service partner here in Oslo suggested that maybe the HDMI connector also doubles as a micro-DisplayPort connector. However, I am not sure that micro-DisplayPort actually exist (even if VESA started the standardization process for this some years ago).

 

Any ideas how to contact Lenovo to settle this?

Hi. Did you get an answer to the mysterious "HDMI / displayport combo" connector? I just bought a 710-14IKB and would very much like to connect it to my monitor using displayport but have no idea what cable to use...

 

Thanks

Hello!

 

No, it is still a mystery! I am currently in contact with Lenovo Norway and they are looking into this (no resolution so far, see below also also).

 

I think maybe that I have found an answer to my second question (regarding the Yoga 900S). Just by accident I came across Lenovos "Option Compatibility Matrix 2017" (very useful):

 

  https://download.lenovo.com/pccbbs/options_iso/ocm_january_2017.xlsx

 

According to this the Lenovo USB-C to HMDI adapters are compatible, while the USB-C to Displayport adapters are not.

 

And there is no mention of a possible "micro-HDMI to Displayport adapter" for the Yoga 710-14IKB....

Last update for the Yoga 710-14IKB:

 

Lenovo Norway could not answer this either (I have checked with several retailers also).

Unfortunately, I guess that we can conclude that HDMI is the only option for the Yoga 710 14" series (no DisplayPort).

Hi there. Yes, I have found the same conclusion. Had several replies from Lenovo UK "support" which were completely unhelpful. It seems that their marketing literature saying "DisplayPort combo with HDMI" is complete nonsense.

 

Good luck!

I've also reached the same conclusion, going to get it replaced hopefully at the store i bought it, as DP was one of the criterias. no solution from lenovo or the distributor.
