However there are a few things you can do to ensure that you can cast from more websites and services. Ultimately, HDMI is so ubiquitous that it will take a long time to phase out completely.If you have a Roku TV connected to your TV, you’re ready to start casting right away. You'd still have to take an HDMI cable with you. Even though 10,000 supported devices sounds like a lot, it's way behind the 3.5 billion HDMI devices in use.Īt this stage, you couldn't feasibly go to a meeting or conference and expect the equipment there to be Miracast compatible. Secondly, Miracast still significantly trails HDMI in public uptake.
Whereas Miracast will display what's on your screen and nothing else, both AirPlay and Chromecast allow users to cast a video in the background while still performing other tasks in the foreground. In fact, many critics believe that both AirPlay and Chromecast are "smarter" thanks to their ability to multi-task. As we discussed earlier, Apple uses its own version of Miracast called AirPlay, while Google's latest Chromecast dongles do not support the technology either. It too has some limitations and drawbacks.Ĭhief among them is the level of competition. HDMI worked well in the era before we became hyper-mobile, but it's starting to look dated.ĭespite the growth and flexibility of Miracast, it would be foolish to pretend that it's perfect. It means that if your content is locally saved on one of those devices, you won't be able to mirror it on a larger screen. The same authentication issues can lead to screen flickering and lag, all of which are frustrating if you're watching a movie or giving a presentation.Ĭompatibility: Tablets, smartphones, and some smaller laptops do not have HDMI ports. On-screen issues: It's not uncommon for the HDMI output to be blank, which is a problem caused by authentication errors. Sure, longer cables are available, but they're harder to keep neat, require more storage space, and cost more. However, if you're in the office and want to connect to a screen for a conference or presentation, it's annoying. This isn't much of a problem for home users.
What makes HDMI vulnerable to usurping? As it turns out, HDMI has a handful of disadvantages that make it pretty inconvenient at times.ĭistance: Your computer can only be as far away from a TV or second monitor as the HDMI cable allows.
