T480s 2018 4K @60HZ Thunderbolt3 or HDMI?

Hello,

 

I have the T480s with built in MX150 Max Q. Can I get 60Hz with a 4K monitor using either HDMI or Thunderbolt 3?

The monitor only has DisplayPort or HDMI, so in case HDMI does only achieves 30Hz can I use an adapter Thunderbolt3 -> DisplayPort to get 60Hz?

 

Thank you Smiley Happy

When in doubt, the PSREF is here to help!

The HDMI cannot do 4k60, but the DP passthrough from the USB-C & TB3 ports will do the job (a simple USB-C to DP adaptor is all that is recommended by Lenovo).

Thank you for your answer, do you know if watching 4k 60fps videos is even possible with this laptop?

Yes, it is technically possible. That being said, I only have a 4k30 TV, so I don't have any personal experience with 4k60 playback.
