![]() Those with a projector located near their equipment who just need to run cabling up a wall or into an attic space, and who will always have access to do so, will have the most future-proof options available to them. While it may seem obvious, the term "future-proof" applies most easily to those who can just swap out their cabling anytime they want to. These last two situations may sound very similar, but one key aspect of dealing with new construction can make all the difference in the world. And the last scenario is when you know you will not have access to replace cabling in the future after the cables are run without cutting holes in drywall. The second situation is if you are doing new construction and have no drywall in place, making access simple now but more difficult later. ![]() The first setup is if you have fairly easy access to add or remove cabling at the projector location now and in the future. We will consider three potential situations. So, the key is to not just think about which cables you should run today, but also how you will replace the cables in the future if you need to and what steps you can take today to make that process easier. Even with HDMI 2.1 coming into the market now, the continued evolution of the HDMI standard, as well as an increase in the data rates for future video and audio formats, are virtually guaranteed. But, if you decide to install a certified 18 Gbps HDMI cable today because it's either less expensive or all you need for now, it’s important to understand that while it may work just fine for a few years, it likely will need to be replaced at some point with a 48 Gbps HDMI cable-or something even more advanced-to get the best possible image quality with the newest generation of video sources and projectors on the market. Those certified cables (as opposed to those which claim this capability but do not carry certification) should be available soon. ![]() Bottom: HDMI-Certified cables have a scannable label on the packaging which can be used to verify the cable's authenticity.Īt CES earlier this month, the HDMI Forum finally announced its Ultra High Speed HDMI Cable Certification Program for full 48 Gbps, HDMI 2.1 cables. Today's HDMI Certified Premium cables are tested by an independent lab to insure that they handle an 18 Gbps signal, while the upcoming Certified Ultra High Speed cables will be guaranteed to pass a full 48 Gbps and provide all features of the HDMI 2.1 standard at whatever length is purchased. Top: The evolution from HDMI 2.0 to HDMI 2.1 means a jump from 18 Gbps to 48 Gbps capacity, with a commensurate leap from maximum 4K resolution up to a maximum of 10K. The key is the speed rating of the cables and that they are certified for that speed. That’s about twice the capacity of the previous generation of HDMI cables, and less than half of the 48 Gbps capacity that the next generation of HDMI 2.1 cables will be carrying. The current 4K standard for HDMI, called HDMI 2.0, is rated to carry up to 18 Gbps of information. That’s right, the 4K standard is going to be upgraded. That’s because the current standard for video to a display has already been announced as obsolete. That’s quite the list of questions to ask, but those are the right ones to ask yourself before any cabling is run to the projector location. later-will walls need to be cut into to run a new cable, or are you dealing with new construction with open access? If you do have access to replace a cable in the future, how difficult will it be to do so, and are there options to avail yourself of now to make that process easier later? Where is your projector going? Is it going at the back of the room with source equipment directly below the projector? Is it going a few feet from the back wall with equipment on the other side of the room or hidden away in a closet? If you're doing a ceiling mount, do you have an attic space above where the projector will be located? What type of access do you have to either add or remove a cable that needs to be replaced or upgraded in the future? What type of access do you have now vs. This means that while a basic answer to this question is often given, especially by builders and installers who just want to get in and out with whatever solution may work today, in the long run the wrong choice could cost you more money and time than is necessary.Ĭonsider your installation. ![]() Wiring to a projector, while very similar to wiring for a television, is also quite different because the wiring is more often buried behind walls and ceilings, which limits access. ![]() What type of cable should I run for my new projector, and are there any other wiring considerations that I need to make?
