Solved!

Pavilion 27 QD display won't display at full native resolution

HP Recommended
Pavilion 27 QD display
macOS 10.13 High Sierra

I have just bought this display to work at home with during the Coronavirus lockdown. It should display at 2,560 by 1,440 pixels (QHD) but all the computers I have tried it with only achieve 1,920 by 1,080. 

 

I have tried a Macbook pro running the latest version of Mac OS High Sierra, a Mac mini running a fully updated copy of Mac OS Catalina and a Microsoft Surface Pro 4. All have graphics cards that will drive a 2,560 by 1,440 display.

 

The MacBook Pro and SP4 connected with a mini Display Port to HDMI adapter and the included HDMI cable. The Mac mini with this and additionally a HDMI cable directly (and a second high quality HDMI cable). The Macs recognise the name of the display but claim it is a 30.5 inch unit with 1,920 by 1,080 pixels. The SP4 says it is a universal PnP display. 

 

Pretty disappointing really. I've ordered a MDP to DP Cable and hope that might help. Hopefully the same solution that applied here: https://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/HP-Pavilion-27q-Display-cannot-reach-p... might help.

 

Anyone got any other ideas? (I don't have administration rights on the SP4 so can't try installing a specific driver.)

Thanks for the reply. Both the HDMI cables I have are labelled hi-speed with Ethernet. One came with the monitor (so would hopefully be sufficiently fast for the full screen resolution) and checking my purchase history the other one should meet the v2.0  specification. It could be the adaptor I suppose. 

 

I have now received a mini Display Port to Display Port cable and that will drive the display at native resolution for both the SP4 and the MacBook Pro. Yay! 

 

Same with the Mac Mini! [having checked the detailed specs for the Mac Mini (https://support.apple.com/kb/SP659?locale=en_GB) - it seems that it supports up to 1080p on HDMI and mDP is needed for higher resolutions.]

 

Update 10 April 2020: It turns out that my mini display port to HDMI adapter was rated only for 1080p. Having purchased a new 4K rated mDP to HDMI adapter I found the display functioned at full resolution with the HDMI cable included with the display (and also the other HDMI cable I have).

 

I guess my question to HP is then: why not include a mDP to DP cable in the box, or at least mention this compatibility challenge in the documentation and/or support pages?

What is the version of your High Quality HDMI cable ? Please use HDMI version 2.0 or above cable and DP-HDMI (ver 2) adapter.

 

Regards.
