NAS with PCIe GPU slot for Video Hardware Transcoding

My setup I have a newly purchased QNAP 872xt .. I have 8x10tb hd Raid 6 and. 2x1tb nvme .. I have upgraded the memory to 32 and installed a gpu gt 1030 .. but I had to remove the thunderbolt card( too wide) .. ok My questions .. when I connect the hdmi cable to the gpu card I get nothing .. only when I connect it to the nas hdmi can I go to hd station .. the gpu is active in qts as qts .. is this the way it is configured I do not connect to the gpu card directly or must I change to vm or container … I want to use the nas for video streaming/plex .. and do you think it is even wise to use a gpu card ( what is it actually doing working in the background .. transcoding and such ) but then I loose the thunderbolt 3 ??
Sorry for so many questions .. new to all this
Any help .. appreciated?

Qnap x72XT /N series NAS GPU card can be used only for Container Station / Virtualization Station. See what other models can do below.


Models where PCIe GPU can be used for Container Station / Virtualization Station/ Hardware Transcoding:

TVS-472XT/ 672xt / 872xt / x72N – Container Station / Virtualization Station

TVS-882 and other x82 series   – Container Station / Virtualization Station

TS-1685 –     – Container Station / Virtualization Station

TS-x77 –  HD Station / Linux Station / Hardware Transcoding / Container Station / Virtualization Station

TS-x73 – HD Station / Linux Station / Hardware Transcoding / Container Station

x77 Note:
1. The 450 watt power supply unit provides a 8-pin (6+2) power connector and a 6-pin power connector for a graphics card.
2. When Virtualization Station uses graphics cards, the NAS will temporarily stop hardware transcoding acceleration for QTS (and vice versa).
3. GPU support for QTS only applies to NVIDIA graphics cards. GPU Passthrough for VM is supported by AMD and NVIDIA graphics cards.
4. TS-877 supports graphics cards with dimensions up to 266 x 119 x 45 mm & 260 x 189 x 38 mm.
5. Consult the Compatibility List for information on supported NAS and graphics cards.





Recommended GPGPU for TS-1677X

Note: A dual-slot expansion card will take up the space of two PCIe slots.


Device compatibility may be affected if development/support for the device’s drivers has been ceased by the manufacturer, third-party contributors, or open-source developers.


Device compatibility may be affected



GPU pass-through is currently only supported by the below NAS models. The graphics card must also be installed in a compatible PCIe slot.

Always check the physical space and power requirements of a graphics card before purchase. For a list of compatible graphics cards, check



Configuring Graphics Card Settings

  1. Go to Control Panel > System > Hardware > Graphics Card.

    QTS lists the available graphics cards.

  2. Identify the graphics cards you want to configure.
  3. Under Resource Use, select an OS or an application.

    Some functions are only applicable for certain models and graphics cards.

    OS or Application



    QTS applications share graphics card resources for transcoding.

    • Select Hardware Transcoding to allow QTS software to use graphics card resources to speed up transcoding tasks. Only one card can be assigned to hardware transcoding.

    • Select Output to use graphics card resources for video output of HD Station or Linux Station. Only one card can be assigned to output.

    Virtualization Station

    Virtualization Station has exclusive use of all graphics card resources.

    Container Station

    Container Station has exclusive use of all graphics card resources.

  4. Click Apply.
