/* Audio support */
'''How fit-Headless solves the problem?'''
: fit-Headless is a small, low-cost HDMI plug that emulates a high resolution display. Once plugged, the Mac Mini / PC detects a connected display and enables the GPU. With the GPU enabled, screen-sharing / remote desktop access can work in high resolution.
=== Does fit-Headless help in running a headless Intel NUC? ===
Yes. See for example [http://www.vfrank.org/2015/04/28/running-the-intel-nuc-headless-with-vmware-esxi/ http://www.vfrank.org/2015/04/28/running-the-intel-nuc-headless-with-vmware-esxi/]<br>
fit-Headless solves a problem known as "AMT/vPro blank screen", see [http://www.tekhead.org/blog/2015/05/ http://www.tekhead.org/blog/2015/05/]
=== What resolutions Audio support ===fit-Headless GS has fit-Headless DP support audio emulation.<br>fit-Headless and fit-Headless 4K doesn't support? audio. === Supported resolutions on fit-Headless emulators ===
Under different OS (Windows, OSX and Linux) available resolutions may vary. Available resolutions depend on OS, display driver and GPU capabilities.
