Updating firmware on blu ray
The HDMI 2.0a outputs are paired with HDMI 1.4a audio outputs, so you don’t have to worry about your legacy A/V receiver working with the player.
If you're not sure, it's easy to check which version of firmware you have: We recommend this method as it's the simplest way to update. First set up the equipment, then download the update over the internet to your Blu-ray player.
Now, two more players can be added to the list, as Philips is rolling out a firmware update that brings Dolby Vision to two of its players.
One of these players, the BDP7502, was actually introduced at CES 2017 with Dolby Vision support as one of its key features but is only actually receiving the technology now.
Early last year, Dolby announced that it was making the technology available in pure software, making it much easier for manufacturers to add support after their product was already on the market, so it’s possibly that in the future we’ll see players that didn’t launch with the intention of supporting Vision adding it via updates.
Other manufacturers shipping Dolby Vision in Blu-ray players include LG, Panasonic, and Oppo.
