Lifebook U7310 & Type C Port Replicator - HDMI only supports 1080p?

Postby RobertP » Thu May 20, 2021 13:58

Hi,

I am trying to connect my Lifebook U7310 via a Type C Port Replicator (NPR44) to a HDMI monitor with 2560x1440 resolution. However I cannot set the resolution higher than 1920x1080. Does the HDMI output of the notebook/port replicator does not support a higher resolution, or am I doing something wrong?

Regards, Robert

Hello Robert!

Please find below the link to Datasheet for NPR44 port replicator:
https://sp.ts.fujitsu.com/dmsp/Publicat ... rt-Rep.pdf

According to it, HDMI supports up to 4096x2160 when only one display is connected.

Best regards,

Hi!

Thanks, that helps!

Do you have any idea why with this setup I am not able to choose more than 1920x1080 in Windows?

Regards, Robert

Hello Robert,

1. Please describe in more detail the configuration. How many displays are connected, which connectors are used, What is the make and model of the external display?
2. Check if all drivers are updated. You may use DeskUpdate.

3. For further investigation System Scan will be required.

Any information you may need to share, please use user.forum@ts.fujitsu.com.

Hi,

The display is an Eizo CG277 connected via a 4K-ready HDMI cable. It is the only external display connected. I have tried to switch off the internal display and use the external display only, but the problem persists. The display works in full resolution with another notebook using HDMI.

I have solved the problem now by going out of the docking stations DisplayPort cable and into the display with HDMI with an adapter. That works fine and in full resolution.

Regards, Robert
