HDMI devices

What if you need to extend a USB 2.0 interface over a long distance? How do you connect a webcam, speakerphone, or other equipment remotely?

Both device types have HDMI in/out and USB ports on the housing. But the functionality, purpose, and price of these devices are different. Let's take a look at these differences.

The ARC (Audio Return Channel) function in HDMI has helped to remove unnecessary communication between TV and AV receiver, soundbar, or home theater. What does the ARC feature mean for twisted-pair HDMI extenders, and how can you use it?

What do you need an HDMI switch and a multiswitch for? What are the differences between them? What disadvantages do low-cost devices have?

What's the difference between a regular twisted-pair HDMI extender and an over-IP. HDMI over-IP extender image compression and video transmission delay. Lenkeng LKV383PRO vs Lenkeng LKV373.

Twisted-pair extenders can be split into two types: 1. only work over "straight" twisted pair 2. work as a "straight" twisted pair, so in a LAN network

What is the purpose of this type of device? There are cases when it is necessary to multiply the signal from one video source (TV-tuner, PC, video recorder) to several displays.

Are you planning to hide this device on a table behind an NVR, TV, monitor, etc.? Or will the transmitter and receiver be placed in plain sight, e.g. on a wall, under a tabletop, or on a surface in some other way?

There aren't many consumers who pay much attention to design when choosing an HDMI extender over a twisted pair network cable. But it can be quite important in some cases. What if you choose a compact type of extender?

Buyers of HDMI extenders often ignore an additional feature: the HDMI pass-through output of the transmitter. I will look at what it is, where it can be useful, and whether it is worth overpaying for it.
