A mini HDMI to HDMI cable (Type C to Type A) connects compact source devices like cameras and tablets to a standard HDMI display — as long as you have the right connector type and a cable rated for your required resolution.
- Your source device has a Mini HDMI (Type C) port
- Your display has a standard HDMI (Type A) port
- The cable supports your target resolution (HDMI 1.4+ for 4K@30Hz)
- Cable length suits your physical setup
- You mistake Mini HDMI for Micro HDMI — they are physically incompatible
- Your cable is an older version that cannot handle your required resolution
- The source port is USB-C or another non-HDMI connector
- The cable is damaged or poorly built, causing signal dropout
Which Devices Use Mini HDMI?
Mini HDMI (officially HDMI Type C) is a compact connector found on devices where a full-size port would take up too much space. Common devices include:
- Digital cameras and camcorders
- Tablets
- Raspberry Pi boards
- Portable recording devices
- Some graphics cards
If you are unsure whether your device has Mini HDMI or a different port, check the manufacturer spec sheet. The Mini HDMI port measures 10.42 x 2.42 mm — noticeably larger than Micro HDMI.
Mini HDMI vs Micro HDMI: Don’t Mix Them Up
The most common mistake is confusing Mini HDMI (Type C) with Micro HDMI (Type D). They look similar but are not interchangeable. Micro HDMI measures just 6.4 x 2.8 mm — forcing the wrong cable will damage the port. Always check your device manual or measure the port before buying.
If your device uses USB-C instead, the connection method is different entirely — see our guide on whether USB-C can connect to HDMI for how that works.
What Cable Spec Do You Need?
| Setup | Works? | Need | Note |
|---|---|---|---|
| Camera to TV (1080p) | Yes | Any HDMI 1.3+ cable | Standard setup |
| Tablet to monitor (4K@30Hz) | Yes | HDMI 1.4 cable | Check tablet output too |
| Raspberry Pi to display | Yes | Mini HDMI to HDMI cable | Pi 4 uses Micro HDMI instead |
| Micro HDMI device | No | Different cable entirely | Wrong connector type |
For most everyday uses — streaming footage from a camera or mirroring a tablet — a standard HDMI High Speed cable rated at HDMI 1.4 covers everything up to 4K at 30Hz, 3D, and Audio Return Channel.
Troubleshooting No Signal
If you get no picture after connecting, run through these checks:
- Confirm the port on your device is Mini HDMI and not Micro HDMI or USB-C
- Switch the display input to the correct HDMI channel
- Try a shorter cable — long cables can degrade signal without a booster
- Test with another cable to rule out a faulty unit
If you are using a USB-C adapter instead and still getting no signal, our article on why USB-C to HDMI is not working covers the most common causes.
Bottom line: A mini HDMI to HDMI cable is a straightforward solution for cameras, tablets, and similar compact devices — just make sure you have Mini HDMI (Type C) and not Micro HDMI (Type D), and pick a cable rated HDMI 1.4 or higher for 4K output.
