    Select Active Series High Speed HDMI® Cable with RedMere® Technology, 40ft

    Reliably connect your home theater equipment to greater distances than with passive cables using this Select Active Series High Speed HDMI® Cable with RedMere® Technology from Monoprice!

    This High Speed HDMI Cable supports the following general features:

    • Active signal regeneration to ensure accurate reproduction over longer distances
    • 10.2Gbps data throughput
    • CL2 in-wall fire safety rating
    • 28AWG copper conductors
    • Gold plated connectors

    It supports the following HDMI features:

    • 1080p resolution at 60Hz
    • 4K resolution at 24Hz
    • 3D video
    • HDMI Ethernet Channel
    • Audio Return Channel
    • Deep Color up to 16-bits per channel
    • x.v.Color™
    • High Definition Audio, including SA-CD, DVD-Audio, DTS-HD Master Audio™, and Dolby TrueHD™

    Note that Active HDMI cables are directional. Check each end for markings indicating whether it should be connected to the source or the display device. Connecting them backwards will not hurt anything, they just won't work until connected properly.

    Note also that only one Active HDMI cable should be present in any single cable run, even if using a switch, splitter, or matrix. Connecting multiple active HDMI cables in series will cause them to fail to reliably transmit the video signal because each is trying to do the same thing.

    TIP: It is a good idea to test cables and connections before installing them inside a wall. If there are any issues or problems, we can help you resolve them before you spend the time, effort, and expense of installing them inside the walls.

    Pros: Picture quality

    Cons: None

    Works great for my application. I use it to connect my computer to my 55 inch TV across the room so I can view video files from my computer on my TV. Quality is great and don't have any complaints

    Pros: I had this hooked up through and HDMI splitter. For once in my life I tested the cable before pulling wire. Did not work. Called Monoprice the next day and support walked me through it (was an easy issue to resolve. . . handshake issue). Cable fired right up.

    Cons: Have not found one.

    I am running this as part of a 3 way hdmi split. Of course the splitter is part of the equation but I did have some lag concerns running this 40 feet. No issues, works great.

    They don't Last

    Pros: Work after initial install

    Cons: Stop working after a few months.
    Require equipment that can power the redmere device in the cable.

    I installed 4 of these in my new house and 3 have now quit working. These were installed in exterior walls that were sprayed with spray foam so there is no way to remove them with out tearing down sheet rock. The only option given by monoprice is to replace the cable which is not an option. Oh and you have to return the cable before they replace it so really they wont do anything. I would recommend going with other cables. I have been very happy with other cables I have gotten from monoprice but have gotten seriously burned by these cables.

    Hi MC,

    Thank you for your feedback and I truly apologize for the issue you have encountered with PID 9171. Regarding the installation in exterior walls, are you referring to the cables being used outdoors, or indoors but out of wall? Also, would you happen to have your order number? I will be passing this information on to our product development team so they may look further into the matter and making the product better. Thanks in advance!

    Excellent long-distance cable

    Pros: Long cable without any degradation in quality or input lag.

    Cons: Only wish there were a few more sizes, 40 was just a bit too long but 30 was too short for my use.

    I wanted to hook my PC up to my TV, and due to my room's setup, I needed to run it along the edge of a door frame and around several corners if I didn't want to otherwise invite a trip hazard (or have unsightly cables along the floor of the room). This cable fit my needs perfectly, I was able to mount it along the edges of the door frame with nearly no fuss - despite being in a circular spool in the shipping box, the cable easily unwinds and shapes however needed. Now I can play PC games on my TV at 1080p60 without any noticeable added lag, and I didn't need to rearrange any furniture or have unsightly cabling across the floor. Great product at a great price.

    Pros: Works great. Top quality cable

    I used this cable with 1x2 HDMI splitter. One run off the splitter was 3 ft and the other was 40 ft and this cable was used. No issues whatsoever. Syncs immediately.
