Cannot run 1440p monitor at full resolution

Hello!

 

I have a problem that max resolution I can get from my setup is 1080p even though my monitors resolution is 1440p.

My setup is: ThinkPad T430p thunderbolt2/mini-displayport -> miniDP to HDMI converter -> HDMI cable into DELL U2518D.

 

I was thinking that maybe I need to buy a miniDP to DP port cable so the connection is more direct? 

 

Pretty sure that this laptop should support larger resolutions. I have another newer HP laptop that connects through miniDP to DP converter and then an HDMI cable and it is possible to select 1440p resolution,

 

Any suggestions?

Do the specs say you can? Should be simple enough to find that out. 

Sounds like you’re exceeding the bandwidth.

From Lenovo's website - 

  • Maximum external resolution: 2560x1600 (DisplayPort)@60Hz; 2048x1536 (VGA)@75Hz; 1920x1200@60Hz (single-link DVI-D via cable 45J7915)

Then there isn’t an issue. Connect it to a proper display or check to that fancy adapter to ensure it supports the res.
