USB-C can carry video, but only if your device supports video out. Here is what you need:

• A compatible USB-C port: Look for terms like video out or DisplayPort Alt Mode in your device specs.
• An adapter or cable: A simple USB-C to HDMI cable works for single displays. Multiport hubs add extras like USB and card readers.
• The right HDMI spec: For 4K at 60 Hz, choose gear rated 4K 60. Higher refresh rates may require newer standards.
• Power considerations: If you want to charge while viewing, pick a hub with Power Delivery pass-through.

Device capabilities and cables vary. Checking the item description and specs on the product page can help you match features before you buy.

A few common issues can stop a USB-C to HDMI setup from working:

• No video output support: Some USB-C ports are data or charging only and do not send video.
• Cable or adapter limits: Using an adapter not rated for 4K 60 or a low quality HDMI cable can block signal.
• Wrong input selection: The TV or monitor may be set to the wrong HDMI input.
• Insufficient power: Hubs may need Power Delivery to stay stable.
• System display settings: External display might be disabled or set to an unsupported resolution or refresh rate.
• Software drivers: Some USB graphics adapters require drivers, which may need updates.

Trying different ports, cables, and a known good display can help isolate the cause.

1. Connect the USB-C adapter or cable to your device first.
2. Plug a certified high speed HDMI cable from the adapter into the TV or monitor.
3. Select the correct HDMI input on the display and wait a few seconds.
4. Open your device display settings to choose mirror or extend, then set a supported resolution and refresh rate such as 1080p 60 or 4K 60.
5. If using a hub, connect your charger to the Power Delivery port for steadier performance.
6. Test with another HDMI port or cable if the screen stays blank.

This process can improve reliability, but results depend on device capabilities, cables, and display compatibility.

Match the adapter to how you plan to use it:

• Compatibility: Confirm your device supports video out over USB-C.
• Resolution and refresh rate: For smooth 4K at 60 Hz, choose gear labeled 4K 60. For higher frame rates or 8K, look for adapters that specify those modes.
• Single versus multiport: Need USB ports, SD slots, Ethernet, or charging while connected? Pick a multiport hub with Power Delivery.
• Dual display needs: If you want two HDMI screens, check product specs and your operating system support.
• Build and length: Consider a short dongle for travel or a longer cable for cleaner setups.

Phones vary widely. You can check support with these steps:

1. Look in the device manual or specs for terms like video out or DisplayPort Alt Mode over USB-C.
2. If listed, use a USB-C to HDMI adapter or hub rated for your desired resolution.
3. After connecting, select the correct HDMI input and adjust display settings if available.
4. If nothing appears, try another display and cable to rule out accessories.

Many phones do not offer wired HDMI output. In those cases, consider using built in wireless casting features on your phone and TV as an alternative. Product descriptions on the item page can help you identify adapters designed for mobile use.
