Yes—if the motherboard’s display output is supported by the processor’s graphics hardware and the ports on the computer and HDTV match. A motherboard HDMI socket alone does not guarantee a picture: a processor without integrated graphics generally needs a discrete graphics card to provide video.
When a motherboard display port will work
Motherboard HDMI and DisplayPort sockets are outputs for the graphics hardware supported by the motherboard and installed processor. They are not independent graphics devices. To use one, check that the processor includes integrated graphics, that the motherboard supports that processor, and that any required BIOS version or setting is in place.
MSI Support’s motherboard external-display troubleshooting guidance, dated August 18, 2023, advises connecting the display to the motherboard’s rear ports when using processor-integrated graphics. It also recommends checking CPU and motherboard compatibility, BIOS settings, and monitor settings. MSI states: “If your processor doesn’t have an integrated graphics card, you will need to use a discrete graphics card to output the display.”
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteIf you have a discrete graphics card and want to use its graphics output, connect the HDTV to the card’s ports. Do not assume the motherboard outputs will carry or mirror the discrete card’s signal.

Choose a cable or adapter for the ports you actually have
Check the output on the active graphics device and the input on the HDTV before buying a cable. The connector’s shape matters, but so does whether that connection path is supported.
| Computer output | HDTV input | Connection guidance |
|---|---|---|
| HDMI | HDMI | Use a standard HDMI cable, provided the HDMI output is active. |
| DVI | HDMI | An HDMI-to-DVI cable is an option for a DVI graphics output and HDMI television input; check the devices’ supported features. |
| DisplayPort | HDMI, DVI, or VGA | Use a suitable DisplayPort adapter or cable for the specific display input. Confirm that the required conversion is supported; do not assume every adapter works in every direction. |
| VGA | HDMI or another digital input | Do not assume a simple cable will convert analog VGA into a digital signal. Verify that an appropriate converter is supported for the particular setup. |
NVIDIA’s connection guide recommends a standard HDMI cable when both ends are HDMI and describes an HDMI-to-DVI cable when the computer’s output is DVI and the HDTV’s input is HDMI. Intel’s TV-connection FAQ lists DVI, HDMI, VGA, and DisplayPort as possible connection types and emphasizes that the computer must have the appropriate output connector. A cable or adapter cannot add graphics capability to a processor or motherboard.

Check the board’s limits instead of assuming all ports are alike
Maximum resolution, refresh rate, HDR support, and audio capability depend on the exact motherboard, graphics hardware, and port. Read the manual or specifications for the specific board and confirm they apply to the installed processor and the output you plan to use.
Example: Supermicro X14SAV-TLN4F
Supermicro’s 2025 manual says the X14SAV-TLN4F’s HDMI port carries high-definition video and digital sound to an HDMI-capable display. For that port, it lists Intel HD graphics output up to 4096 × 2160 at 60 Hz with HDR. The manual also describes DisplayPort and adapters for displays with VGA, DVI, or HDMI connections. These specifications apply to this model and its supported graphics configuration; they are not general limits or guarantees for other motherboards.

A quick compatibility check before connecting
- Identify the active graphics device. Decide whether you intend to use processor-integrated graphics through the motherboard or a discrete graphics card.
- Verify processor support. Check that the CPU includes integrated graphics if you plan to use motherboard outputs, and confirm that the board supports the CPU. Check the board maker’s CPU list for any required BIOS version.
- Inspect both ends. Note the actual output connector on the active graphics device and the available input on the HDTV.
- Match the connection. Use a direct cable for matching supported ports, or a specifically compatible adapter when the ports differ.
- Check display settings and specifications. Confirm the board’s supported resolution and refresh rate for the chosen port, then check BIOS and monitor settings if there is no picture.
If the HDTV shows no picture
- Make sure the cable is connected to the output you intend to use. For processor-integrated graphics, that is a rear motherboard display port; for a discrete card’s output, use a port on the card.
- If using a motherboard port, verify that the processor actually includes integrated graphics and is supported by the motherboard.
- Check for a required BIOS version or graphics setting, and select the corresponding input on the HDTV.
- Recheck that the adapter supports the specific source and display connections. Similar-looking connectors do not guarantee compatible signal conversion.
- Confirm the chosen resolution and refresh rate are supported by the exact board, graphics configuration, and display connection.
