TS-140 4k video?

[Phlerb 0]

Has anyone gotten 4k video to output consistently? I have it hooked up to my 4k Samsung, but it keeps blacking out then coming back. It shows ok for 3-10 seconds, then the screen goes black.

 

I did have to VNC into the server and select 30p as the output, as the 23 auto selected would not display on the Samsung.

 

Is this due to the onboard video? or maybe the TV?

 

Thanks for any ideas.

How is the computer connected to the Samsung: HDMI? Other?  If it's HDMI, is it possible you're experiencing HDCP issues?

Probably Intel's terrible drivers at fault.

What processor is in the TS140?

What is the OS?

Are you running the latest drivers from Intel?

Sorry, Here are the server details:

 

Os: windows 8.1 64 bit

Connection: Display Port out with a DP to HDMI adapter from Amazon, to HDMI in.

 

Intel drivers, version 10.18.10.3412, which seem to be the latest according to the Lenovo site

I wouldn't think HDCP would play into this scenario.

 

Thanks

I can't help but think the DP to HDMI adapter is going to cause issues.

 

I don't have a 4k screen, or I could check it here.

The cable would need to support HDMI 1.4.

 

Intel has newer drivers:

The CPU in your TS140 determines which graphic controller you have.

I have the i3 variant, and I have tried 2 different cables, I will try the new drivers now.

 

thanks

You should also check with Lenovo support to confirm that the TS140 supports the resolution you are trying to get.
