        I have a similar problem. After the inital boot, no signal is detected. If i unplug/plug the HDMI cable, the desktop reappars. This is on Ubuntu 18.04.

          crypt1,

           

          What's your TV model? Can you see NUC splash screen and BIOS (after pressing F2) when UHD Color is ON?  I tried several Samsung 4K TVs (2017 and 2018 models) and when UHD Color is ON TVs show "No Signal" during POST and in BIOS.

           

          Thanks,

          Peter

            I just stumbled onto this thread because I just recently bought a NUCC7CJYH and was "kinda" thinking of installing Linux (Ubuntu) on one of the SSD's I bought for it (the other WILL get Windows 10/64-bit). So I was doing my due-diligence about a Linux install and landed here.

             

            While I may still install Ubuntu on one of the SSD for this NUC on of these days, it won't be the first to install because I just finished going through all the BS "rigamarole" at the Ubuntu for NUC website and this is like applying for a Government Security Clearance! (and I'm ex-USAF, a Capt., combat pilot and instructor!) Hesus! A SSO account required, SSH's Keys required, blood type, bend over and spread rectal exam .... OK I'm being facetious and exaggerating, but this is the list I WON'T NEED to install Windows 7, 8.1 or 10 - just a USB CD/DVD Drive; and why Linux will always be a Nerds OS and a pain in the Colonoscopy to install. (from Ubuntu site):

            Minimum requirements

            • An Ubuntu SSO account with an SSH key
            • An Intel NUC with BIOS updated to the latest version (update instructions)
            • 2 USB 2.0 or 3.0 flash drives (2GB minimum)
            • A monitor with an HDMI interface
            • A Mini HDMI to HDMI cable
            • A USB keyboard and a mouse
            • A monitor with VGA or HDMI interface
            • A VGA or HDMI cable
            • A network connection with Internet access
            • An Ubuntu Desktop 18.04.1 LTS image
            • An Ubuntu Core image

             

            I don't know, maybe Linux Nerds want to keep this OS dark and mysterious and awful to install for the majority of computer users that are "tinker IT level", but you'd think after 30 years the Linux bunch would figure out that only 1% of the world that installs Linux is telling you something. It's not worth the trouble and time required to just figure out how the install the damn thing and then another couple months of working out all the bugs that don't work. A 1000 piece jig-saw puzzle is a piece of cake compared to Linux installs.

             

            Now I think I'll relax and tinker with a General Electric T700-GE-401 Jet Turbine engine .... easier than Linux; then install Windows 10 on the NUC, while watching American Ninja, in 10 minutes.

              Have you thought about trying this, just for kicks?

                Interesting.  So is this going to run as a "Dual Boot" on start up or as a sort-of Linux Emulator within Windows (kind of like Boot Camp on Mac OSX running Windows within?

                 

                Windows 7 and 10 runs decidedly slower than "native" when running in Mac OSX Boot Camp. This NUC is no power-house i5 or i7, so I'm concerned about a slow running Linux on top of Windows.  I also had some interest like the threads OP in running KODI within a pure native Ubuntu install. I already have KODI installed in a couple hacked D-Link Boxee Box'es which has Intel Quad-cores in them.

                  No idea how it will work.  Dual boot?  Not necessary if you can run BOTH concurrently.

                    Ah ha, want me to be there guinea pig huh on this Linux overlay on Windows?

                     

                    For the OP, my new (w/o and OS installed yet) see's my 30" Philips "2k" LED/LCD TV on HDMI 3 slot just fine. sure you selected the right input on the TV control?

                     

                    Anyways, I Got a problem, I finally got my 8GB of Crucial DDR4 2400 RAM finally yesterday for my newly acquired NUC7CJYH1, installed a new SanDisk 500GB SSD and connected a LG USB2.0 external CD/DVD/Blueray drive we use with a couple Windows notebooks w/o internal optical drives.

                     

                    When I inserted a MSFT OEM Windows 7 64-bit installation disk (I plan to use a Win 10 update disk to get me to Win 10) and booted the NUC I got an error on the screen "Image Authorization Fail. System can not (should be cannot) boot to this device due to Security Violation. Press enter key to continue".

                     

                    What is this??? We've used this same drive on numerous HP and a Dell Notebooks to update to like 7 and 8.1, never seen this error.  The NUC also won't recognize a "Ultimate Boot CD" rescue / repair disk (used often on various Windows 7, 8.1 and 10 notebook and desktops - no problemo booting to it).

                     

                    Does the NUC not like ext USB 2.0 CD/DVD/Blueray drives? How the heck am I supposed to install an OS off a factory install DVD??

                     

                    Thanks for any advice.
