    NUC7i5BNH Support for 2560x1440@60 over HDMI Issue (plus audio)

    kennwalker

      Just finished bringing up my NUC7i5BNH with a clean install of Windows 10.

       

      When the generic Windows driver was in charge before I installed the Intel Graphics driver, I had the native 2560 x 1440 displayed on my monitor over the HDMI cable. As soon as I installed the iGFX driver (GFX_WIN10_64_15.46.2.1.4729) the display dropped to 1920 x 1080 and I cannot for the life of me find a way to return to the display's native resolution.

       

      I tried a custom setting in the Intel Graphics Setting application and it says that the requested setting is outside the bandwidth limitations for the device (which it shouldn't be).

       

      Under the "Options and Support" section of the Intel Graphics Setting application, the application does see that 2560 x 1440 @ 60p Hz is a supported monitor mode. The monitor is from Monoprice and it's a 27" display.

       

      The Intel Driver Update Utility doesn't register a version number for the graphics driver and reports it as "Unknown".

       

      I don't know if it's related, but the system also doesn't recognize the audio capabilities of the monitor either.

          Hi kennwalker,

          Thank you for reporting this matter. Let me help you with this issue. At this moment, I am reviewing this problem and report back as soon as I get any news about it.

          Thank you for your patience.

            Hi kennwalker,

            Thank you for your patience.

            I was using same Intel® NUC model and tried connecting HP Z27s with maximum resolution 3840 x 2160 @ 60 Hz via HDMI and it was able to maintain the highest resolution while playing video and sounds.

            Please try the latest graphics drivers for your Intel® NUC version 4771 and if possible test different HDMI cable.

              New Driver, new HDMI 2.0 cable, same result.

              While the EDID reports the 2560x1440 resolution with the Intel Graphics driver installed, the NUC won't allow it with the Intel graphics driver.

               

              If I remove the Intel driver and go back to the default Microsoft Basic Display Adapter driver, I get the 2560 x 1440 resolution on either cable just fine.

               

              By process of elimination, I have to assume that something about the combination of the Intel graphics driver and this display over HDMI do not agree.

               

              I cannot use the basic driver because I need the graphics performance enhancements but I also cannot throw away resolution that I paid extra money for with the monitor. I may need to return the NUC, which is annoying, because I bought it directly on EPP right before I left Intel this month and picked up a copy of the OS (which I can't return) and a dedicated drive, (that I probably can't return either).

               

              *sigh*

                Hi kennwalker,

                Sorry to hear this is still happening. I tested the Intel® NUC again with the latest graphics drivers but I did not get any problems.
                I recommend contacting Intel customer support and check for warranty options for the Intel® NUC.

                  I had the NUC replaced.

                   

                  I also went and got brand new HDMI 2.0 compliant cables just in case the cable I had was bad. I'm still seeing the same behavior.

                   

                  I still believe that this really does look like a driver limitation. Can someone ask the driver team what their behavior is with HDMI signals that may not accurately conform to the 1.4a or later signal standard. Do they default to 1920x1080 regardless of what the EDID says from a resolution perspective?

                   

                  It's clear the graphics software is reading the higher resolution from the EDID as it reports it in the Intel Graphics Settings application.

                   

                  I'll do some more testing with other systems and video sources over hdmi to the monitor, but this looks like a driver issue with the combination of this monitor and the NUC at this point.

                    I have a NUC7i5BNH and have both a Dell U3415W (3440x1440) and a Dell U2717D (2560 x 1440) monitor connected. I normally have the U3415W connected via display port and the U2717D connected via HDMI. While I normally have my setup configured to have the audio coming from the U3415W (display port), in this configuration I am able to get sound and video on the U2717D (hdmi).

                     

                    Due to previously reported issues with the latest version of the display drivers I was troubleshooting and for a few days had the monitors connected the opposite way (i.e. U3415W via HDMI, U2717D via display port) and was also able to get sound and video on the U3415W via hdmi.

                     

                    I am using Intel Graphics Driver 21.20.16.4663 and Windows 10 Version 1703 (build 15063.540). I also have the Dell monitor drivers/configuration files installed. My Intel HD Graphics Control Panel also displays the correct driver version.

                     

                    I also completed 2 clean rebuilds of this machine 2-3 weeks ago while troubleshooting the issues with the latest version of the display drivers. Neither time did I experience issues with getting audio/video to work.

                     

                    When completing a clean install there typically is a recommended order in which to install the drivers etc e.g. I believe the Intel Chipset Device Software should be installed before the graphics, network drivers etc. I'm not suggesting this may be something you haven't done, I am just mentioning it as I wasn't aware myself of the order to install until I did the last clean install. Admittedly I haven't noticed any difference in installing the drivers etc in a random order or a recommended order.

                      You're running an older version of the driver than I am, so I guess I should take a look at whether I can downgrade to that one to see if it makes a difference. My current driver is 22.20.16.4771

                        Driver versions later than 21.20.16.4663  have a number of reported issues with 4k and other high resolution screens e.g. 3440x1440 resulting in video/audio black outs. I experienced this and rolled back to 21.20.16.4663 which for now resolves the black out issue. A number of threads cover this.

                         

                        However that may be completely unrelated to the issue you are experiencing.

                         

                        I'm assuming that the monitor doesn't come with a configuration/driver file you can install for it?

                          No, there's no signed INF file. It's from Monoprice and you get a low price because...
