Case: SilverStone SST-DS380B ITX Problem: On installation of Ubuntu 16.04 LTE there was no output from the HDMI. A PCIe card was installed on the single PCIe x 16 slot and then there was a signal for a monitor. The BIOS also does not seem to provide some way to activate the HDMI's. The CPU does seem to have an onboard GPU. How can the HDMI's be activated without having to install a graphic card? _________________________________________________________________________ Pingumann wrote: Tried everything in Bios. Multimonitor does not work. Setting both onboard IGPU and Internal PCIe Card as active at all times does not work either. Only classical DVI or HDI work. Setting to only HDMI for CPU IGPU dieactivetes PCIe GPU Card. HDMI only works on some Systems. Auto Update with Internet worked. Newest Firmware installed. Did not solve erratic Monitor output behaviour. All the cards will be returned to the Supplier! It does not behave as advertised. Suggestions welcome for an ALTERNATIVE Mini-ITX/ac (170x170 mm) Form Factor,  Intel Z170 LGA1151 Core i7, >6xSATA3, 4xDDR4 3400 OC and at least 2 PCIe connectors? Does not have to be ASRock. _________________________________________________________________________ After extensive searching and trying many different cables and options in the Bios/AHCI set-up it is now working as needed. The documentation and in-line help of the Aptio Setup Utility is pathetic.   Used startpage.com to find the setup options. *************************************************************************** Statement/Question [S/Q] There are no options to activate the HDMI ports, nor is there any reason that should be necessary. Answer [A] The HDMI gets activated by the "Primary Graphics Adapter" [Onboard] and "IGPU Multi-Monitor" [Enabled] options. Other settings disables the HDMI.  Sorry to say, but Ubuntu is not an officially supported OS. This board is not advertised as working with Ubuntu of any version.   Why do you think it is compatible with Ubuntu?   Ubuntu (almost all Linux Distros for that matter) is compatible with almost anything. Modern AHCI set-ups are all Linux compatible.   My question is, does Ubuntu 16.04 LTE have a built in video driver for use with the Intel HD 530 graphics?    Linux Kernel uses almost all CPU's and those with internal GPU's - no drivers needed.   If a video driver for the Intel integrated graphics is not installed, then it will not function. If the driver is not compatible, then it will not work correctly.    What video driver for the Intel integrated graphics are you using?   Only a Windows problem - Linux does not need drivers. In fact, the kernel can handle all CPU's. Not aware of any internal GPU's that are not supported by the Linux Kernel.   I don't understand these statements from your second post: Statement [S]: Only classical DVI or HDI work.    It meant: Only using either DVI or HDMI, but not both worked simultaneously. New info is that using a duplex DVI-HDMI-cable that works both directions the Multi-Monitor function works. [Checked - Works] Setting to only HDMI for CPU IGPU deactivates PCIe GPU Card.  Both work with the special cable and the IGPU Multi-Monitor option [Enabled] HDMI only works on some Systems. No problems with Monitor/TV systems that have a HDMI input as one of the standard connections installed in the factory. Only a special cable mentioned above works well. HDMI-HDMI-cables in combination with HDMI-DVI-adapters do not seem to work with the ASRock MoBo's. The HDMI-HDMI-Cable with a HDMI-DVI-Connector combination works with MacBookPro's. That is why we were surprised when it did not work with the ASRock MoBo's.  What does classical DVI mean? The standard input connectors on the Monitors from factory are DVI (it used to be RGB and VGA before DVI came). Unless you have IGPU Multi-Monitor enabled in the UEFI, using the onboard graphics (having a cable connected to it and to a monitor) will cause a video card to be not used. New Info is that both work together as Multi-Monitor as described above. The problem is with HDMI cables with HDMI-DVI adapters that seem to send signals only in one direction. The "HDMI only works on some Systems" statement is curious, what does that mean? What does "Systems" mean? Systems are Monitors and modern TV's which have HDMI inputs.
