Bringing Miracast devices to the next level with its industry-first 4K60Hz specs, Ergotech’s MD3090FV paves the way for better home theater experiences.

The Trend of Video Transmission

Smartphones and tablets have become everyone’s favorite pastimes in the modern world. Stream videos, engage in social media, play games or simply read news - versatility in these devices provide us with endless entertainment. The screens of these smart devices are rather small in size compared to other displays, however, because they were originally designed to be for personal use,  leading to the growing demand of screen mirroring.


Technologies like Mobile High-Definition Link (MHL) and Miracast have been on the market for some time to meet the demand, but as the demand grew, so did expectations for better wireless experiences. ErgoTech’s new Miracast TV dongle is here to impress with its ultra high quality wireless connection (4K@60Hz) and up to 10 meters of connection range.

4K60Hz and 4K30Hz: What’s the Difference?

For those who are not great with specs, 4K (Ultra HD) display in television and consumer media refers to a horizontal display resolution of approximately 4000 pixels, meaning that it is 4 times more detailed than 1080p (Full HD). 4K means crispier display and more details.


Hz, on the other hand, measures the frame rate. 60Hz (also known as 60 fps) simply means that 60 frames are shown every second - twice than the mainstream 30Hz technology. 4K60Hz enables smoother display of fast-moving objects on screen - think car racing, gun fights and sport games. No more ghosting and blurring.


Here’s an interesting fact for you: two-time Oscar winner Ang Lee shot the film Billy Lynn’s Long Halftime Walk at 4K120Hz (or 4K, 120fps), a much higher frame rate than most movies, which is 24fps. An avant-garde step applauded and critiqued by many, the movie was too crisp and clear that some claimed that its visuals were hyper-real and unnatural.


Why Does Longer Distance and High Specification Matter?


When it comes to video transmission, there are 2 fundamental rules to keep in mind.


Rule 1 - The higher the video quality, the shorter the connection range.

To give you a more concrete idea, the max distance using HDMI cable to extend FHD is 15 meters; whereas with 4K30Hz, better video quality, the range drops to 5-8 meters and 4K60Hz, usually below 2. You’re likely to suffer from no video signals, low connection stability or snow noises on screen.


Rule 2 - Given the same max extension distance, higher specification means higher stability.

Take 4K60Hz and 1080p for example - if both has a max extension distance of 10 meters, 4K60Hz products will provide more consistency and handle lower quality content with greater compatibility because higher specification products are able to transmit more information and is downward compatible.  It’s worth mentioning that some HDMI 2.0 cables on the market can play 4K@60Hz over 3 meters of connection range, but only with the help of video boosters and costs a lot more.

Cable or Wireless?


The benefits of wireless devices is beyond dispute. Aside from aesthetic reasons, cables come with restrictions as well. Generally speaking, the distance from a TV to a sofa in a typical living room setting is at least 4 meters. To hide the cables completely so it does not spoil the interior design, you will need at least a 15-20M cable. Another option is to connect with a shorter HDMI cable (2 meters) and place your handheld devices next to the TV . Imagine the buzzkill of having to get up and play or pause a video during your favorite TV series. No one wants that or tripping over long cables. This is just a small part of why the market is shifting towards wireless products.


I don’t want to make wireless products sound perfect, because it’s not. There is one underlying problem that we cannot ignore - lost of connection, the achilles’ heel of all wireless products. Wireless devices utilizes the current WiFi technology, making it vulnerable to interference from radios, just like Bluetooth products are. We’re not diving deep into this, but thanks to new technology like WiFi 5G and advance in chips, this will no longer be a problem.


Other Popular Miracast Products


Here are some popular Miracast products on the market.


There are tons of 1080p FHD products to choose from thanks to numerous Chinese manufacturers. The biggest differences between these products are compatibility and video quality. In short, the price is the best indicator of the quality. Among them, Chromecast 3 is the leading product and has great value. A limitation of Chromecast series, however, is that it requires an app to mirror smartphone screens to TVs and Chromecast ultra (4K60hz support).


Anycast 4K, another popular choice, is the first most popular 4K30Hz model on the market. Some compatibility issue exists but still a product with great value.

As for 4K60Hz mira screen products, Ergotech’s MD3090FV is currently the first and only one on the market that can directly mirror smartphone displays to TV, projectors, and car monitors, without having to install any apps. Though being the first to hit the market, the performance of MD3090FV is impressive. In test, MD3090FV can wirelessly transmit 4K@60Hz video over 10M stably. It also claims to be able to operate under multi-operation systems such as Android, iOS, Chrome OS, Windows OS.
