Hi everyone, Recently, a friend of mine purchased two HP ZR2740w displays for her home office. We connected the two displays, but we cannot set the resolution correctly. Any resolution above. The HP ZR2740w 27' LED IPS Monitor delivers massive 2560 x 1440 resolution, a 16:9 aspect ratio, and 3.7 million pixels in an ultra-modern and sleek design that perfectly complements HP Z Workstations.

HP 27 inch ZR2740w drivers are tiny programs that enable your Monitor hardware to communicate with your operating system software. Maintaining updated HP 27 inch ZR2740w software prevents crashes and maximizes hardware and system performance. Using outdated or corrupt HP 27 inch ZR2740w drivers can cause system errors, crashes, and cause your computer or hardware to fail. Furthermore, installing the wrong HP drivers can make these problems even worse.

Recommendation: If you are inexperienced with updating HP device drivers manually, we highly recommend downloading the HP (Hewlett Packard) 27 inch ZR2740w Driver Utility. This tool will download and update the correct HP 27 inch ZR2740w driver versions automatically, protecting you against installing the wrong 27 inch ZR2740w drivers.

I've got the two pieces of hardware above. For the dell m4800, it has the i7-4700mq and nvidia quadro k1100m running windows 8/10. Enabling or disabling switchable graphics from the bios doesn't solve the issue below:

When I plug the monitor via displayport directly to my laptop, the monitor is not detected, it never wakes up, and the laptop doesn't see anything. If I use a displayport to dvi adapter, the monitor is seen, but the max resolution is only 1280x720.

What do I do? I know the monitor works and so does the displayport cable, I plug it into another machine and I get my native 1440p resolution just fine.

Since HP's cable is bloody expensive, you can add the pull-up inside the monitor itself. This allows it to work with any DP cable.

The pull-up that worked for me was 10k (even if the specs say it should be 100k - I tried and the monitor wasn't detected). Solder it between C278 (it's connected to DP pin 17, AUXn) and unfitted nearby resistor that goes to DP pin 20 (3.3V power).

You have to use a non-standard DisplayPort cable for HP ZR2740w: PN: HP 729896-001. I bought one from here and display was detected correctly with 2560x1440.

This note from Lenovo website applies:

The HP ZR2740w monitor requires a specific DisplayPort cable offered by HP in order to work with ThinkPad Pro/Ultra Docks and ThinkPad OneLink Pro Docks. This is due to a decision HP made with the internal design of the monitor. The special DisplayPort cable adds a resistor to the AUX signal which allows it to work properly.

Apr 30, 2018  The NVIDIA binary driver seems to be very weak at reliably probing this information from the monitor and relies on additional information in xorg.conf. To fix this you can add more resolutions by entering the following in a terminal.

Details from RichardJS about HP's mistake (aka. 'design decision') in the monitor circuit:

The 729896-001 SPS-ASSY cable DP with AUX-N cable is a workaround for a resistor selection made in the ZR2740w monitor, on the DisplayPort AUX negative channel. The 'pull-down' resistor used in the monitor AUX-negative channel is excessively 'strong' in the parlance of electrical engineering, and causes the DP re-driver in the dock to remain in sleep (low power) mode.

This is because the DP signal re-driver in the dock monitors the AUX-negative voltage level to determine when a monitor is connected (which then causes it to wake up from low-power mode). https://nforenperra1970.mystrikingly.com/blog/ilok-crack. The system DP port does not have a re-driver.

You'll have to review the DisplayPort specification from VESA for the AUX-N resistor value requirements on the source and sink, if you are so inclined.
