Common Questions
Can I connect DVI to HDMI?
Yes. Digital DVI (DVI-D/DVI-I) and HDMI use the same TMDS signaling, so a passive DVI-to-HDMI cable or adapter connects them and carries the video. DVI carries no audio, so add a separate audio connection. DVI vs HDMI »
What's the difference between HDMI and DisplayPort?
Both carry digital video and audio. HDMI is the standard for TVs and home theater (adds CEC and ARC/eARC); DisplayPort is built for PCs, with more bandwidth headroom and multi-monitor daisy-chaining. HDMI vs DisplayPort »
What HDMI cable do I need for 4K?
For 4K at 60 Hz with HDR, use a Premium High Speed HDMI cable (18 Gbps); for 4K at 120 Hz, an Ultra High Speed cable (48 Gbps). Cables are rated by bandwidth, not version. HDMI cable types »
Do I need HDMI 2.1?
Only for 4K at 120 Hz gaming, 8K, or lossless Atmos over eARC. For 4K at 60 Hz movies and most TV, HDMI 2.0 is plenty (and 2.1 is backward compatible). HDMI 2.0 vs 2.1 »
Does USB-C carry video?
Only if the port supports DisplayPort Alt Mode, Thunderbolt, or USB4. USB-C is a connector, not a video standard — look for the DisplayPort or Thunderbolt logo by the port. USB-C as a display cable »
