Not every USB-C cable carries video. To send video, you’ll want a cable or adapter that specifically supports video standards.

• Look for: “DisplayPort Alt Mode,” “HDMI Alt Mode,” “USB4,” or “Thunderbolt 3/4.”
• Check the spec callouts: Phrases like “4K@60Hz,” “8K@60Hz,” or “DisplayPort 1.4/2.1” indicate video capability.
• Confirm direction: Most are one‑way (USB‑C device to HDMI/DisplayPort display). Some specialty options are labeled for HDMI source to USB‑C display.
• Verify your device: Your laptop, tablet, or phone must support video out over USB‑C.

You can filter and compare video-capable USB‑C cables on Walmart.com by reviewing the product descriptions and specs. Results can vary by device and cable combination.

Start with what you need to connect and the picture quality you’re aiming for.

• Resolution & refresh: Match the cable to your target (1080p, 4K@60Hz, 4K at higher refresh, or 8K).
• Connector type: TVs typically use HDMI; many monitors benefit from DisplayPort. Older displays may need VGA or DVI.
• Standards: Look for USB4, DisplayPort Alt Mode, or HDMI 2.0/2.1 in the description.
• Power & data: If you also need charging, consider USB‑C cables with 100W or 240W PD and stated video support.
• Length & build: Choose a length that avoids strain; braided or reinforced ends can help durability.

On Walmart.com, compare specs and customer reviews to find a good fit.

Many devices use USB‑C for video through “Alternate Mode” (like DisplayPort Alt Mode) or via USB4/Thunderbolt.

1. Confirm your device supports video out: Check for terms like DisplayPort Alt Mode or Thunderbolt in its specs.
2. Pick the right cable: USB‑C to HDMI for most TVs, or USB‑C to DisplayPort for monitors, matched to your desired resolution/refresh.
3. Connect and select input: Plug in the cable, then switch your TV/monitor to the correct HDMI or DisplayPort input.
4. Adjust display settings: In your device’s display menu, choose mirror or extend and set the resolution/refresh rate your display supports.

This setup can offer a simple, driverless connection, but results depend on your device and display capabilities.

USB‑C ports vary. Some only charge or transfer data, while others send video.

• Check your device’s specs: Look for “DisplayPort Alt Mode,” “video out,” “USB4,” or “Thunderbolt 3/4.”
• Review the user manual or product page: Manufacturers often list video-output support and maximum resolution/refresh.
• Match with the right cable: Use a USB‑C to HDMI or DisplayPort cable that states 4K@60Hz (or your target spec).
• Test with a known-working display: Connect and see if a second screen is detected; if not, it may be a non-video USB‑C port.

On Walmart.com, you can compare cable capabilities, but your device must also support video for the connection to work.

A few common factors can cause issues, and checking them can help.

• Device support: Some USB‑C ports don’t output video. Confirm your device supports DisplayPort Alt Mode, USB4, or Thunderbolt.
• Cable direction: Many cables are one‑way (USB‑C source to HDMI display). If yours is the reverse scenario, you’ll need a cable labeled for that direction.
• Resolution/refresh mismatch: Try lowering the resolution (e.g., 1080p) and retest.
• Display input: Make sure the TV/monitor is set to the correct HDMI input.
• Cable length/quality: Very long runs can be less reliable at higher resolutions.

If compatibility still seems off, review the product specs on Walmart.com and your device manual. Results can vary by setup.
