FIND A DEALER OR DISTRIBUTOR
OK, so you understand just how important a wireless HDMI transmitter can be. But do you know what separates the good wireless HDMI transmitters from the bad ones? Find out below.
1. It’s easy to carry around
The entire point of going wireless is to avoid the struggle that comes with stringing cables. So, if your wireless HDMI transmitter isn’t easy to take everywhere, it’s not very good. The good wireless HDMI transmitters are incredibly lightweight. In fact, your smartphone is probably heavier! These transmitters are designed to fit in your pocket or carrying case so that you can have access to the latest technology anytime, anywhere.
2. It’s uncompressed
Video looks its best when it hasn’t been fiddled with too much. Unfortunately, “compressing” is the tech industry’s term for fiddling with it, so if you’ve got a transmitter that compresses video as it sends it from Point A to Point B, it’s never going to look right.
What’s going to be wrong with it?
Compressing takes the details out of video, and when you think about it, that makes perfect sense. After all, compressing is done to make video files smaller, so that they’re easier to transmit. But the more your transmitter “squeezes” the video, the more it’s going to squeeze right out of it! In the end, you’ll wind up with colors that aren’t as vibrant and shots that aren’t as sharp.
3. It has a teeny-tiny latency
“Latency” is the fancy tech term that describes the time it takes for your audio and video files to get from Point A to Point B. The higher your wireless HDMI transmitter’s latency is, the longer it will take. As a result, you need to be on the lookout for a transmitter that has less than one millisecond of latency. Anything longer is going to come with delays that make your work harder — and that’s simply unacceptable!
4. It comes with zero frame delay
Frame delay is the fancy way of describing how long it takes to process every bit of data in your sequence. A delay of 1/30 of a frame (33ms) might not seem like much, but it will definitely be noticeable! That’s because every time a new image or sound pops up, you’ll have to wait 33 milliseconds to see and hear it. As a result, your video will seem sluggish. (Ever see the word “buffering” pop up on an internet video? That’s the frame delay!)
But when you have a transmitter that comes with zero frame delay (less than 1millisecond), you don’t have to worry about video that chugs along at a slow pace. Since there’s no delay in processing everything, your finished product will look and sound just as sharp as it did in real time!
5. It comes with dynamic frequency selection capabilities
Since your transmitter is working wirelessly, it needs to be able to access the frequencies on which your audio and video actually travels! Unless you’re OK with the transmission process taking forever, you need a wireless HDMI transmitter that is certified to handle dynamic frequency selection.
What does that mean?
Basically, it’s a fancy way of saying that your transmitter can assess all of the 5 GHz frequencies and determine which one offers the most efficient route. Since frequencies can get clogged with traffic and interference, you need a transmitter that knows how to avoid these slow-downs. Think of it like having a chauffeur who knows all of the back roads, so that you don’t get stuck sitting in bumper-to-bumper traffic on the expressway!
