How to Hide Samsung One Connect Box & One Connect Cable (2024)

How to Hide One Connect Box Behind Wall Mounted Frame TV

How to install Samsung Frame TV 2024

Overview

This article is written to explain how One Connect Box can be hidden behind the Frame TV mounted flush to the wall. Frame TVs from 2018~2024 come with One Connect Box that supplies power to the TV via One Connect Cable.

You may have thought – “Why not just hide the One Connect Cable inside a wall?

Well… Since One Connect cable supplies POWER as well as AV signals from One Connect Box to the TV, hiding One Connect cable inside a wall is out of the question because it is AGAINST the CODE in 99% of the regions in North America, so that’s not even a viable option.

For those of you who have Samsung 8K Neo QLED TV that comes with “Slim One Connect Box”, you can also follow directions here as the process is the same if you want the same look as flush wall mounted Frame TV.

The latest 2024 Samsung Frame TV’s “Slim Fit TV Wall Mount” & previous generations’ “No Gap Wall Mount” are both designed to keep the TV flush against the wall. Therefore, you need to install an AV Back Box inside your wall for One Connect Box & One Connect cable to be hidden behind the wall mounted Frame TV.

*Important Note: AV Back Box dimensions require studs to be minimum 16 inches on center (which is standard by the way). If your studs are further apart than 16″, then it’s ok as you can just use the dog legs included to secure the AV Back Box to the wall. But if your studs are closer than 16″ on center, then unfortunately AV Back Box won’t fit.

    Space required for AV Back Box installation

    Before trying to install the AV back box, you need to first determine whether or not your wall will be able to accommodate it.

    Type of Walls Applicable For AV Back Box Installation Include:

    • Drywall with 2×4 Wooden Studs (standard for newer Houses & Townhomes)
    • Drywall with 2×4 Metal Studs (newer commercial buildings and *some condos)
    • Plaster Interior Wall with Wooden Studs in older homes/buildings with at least 4″ of clearance
    • Custom-made walls with at least 4″ of clearance from surface of the wall to the back

    Type of Walls NOT Applicable For AV Back Box Installation Include:

    • Concrete walls (usually in condos & apartments)
    • Brick walls (usually above wood burning fireplace)
    • Drywall with 2×2 metal studs (usually in condos & apartments)
    • Exterior Plaster Wall without any studs (older homes & buildings)
    • Cinder block wall
    • Any wall that doesn’t have cavity

    For 17×14 inch AV Back Box installation, required space inside the wall are: 17″ (H) x 14 3/8″ (W) x 4″ (D).

    Your wall must have at least 4″ of depth/clearance in the wall from the surface of the wall to fit AV Back Box into a wall. *For example: 2×4 studs + 1/2″ drywall equals to 4 inches in depth which is standard in newer houses & townhomes. 4 inch clearance is the absolute minimum depth required for AV Back Box to fit flush inside a wall.

    Also, there must be at least 14 3/8″ of clearance between the 2 studs. *Standard stud spacing is 16″ apart-on-center which equals to 14 1/2″ of clearance between 2 studs.

    AV Back Box Installation for 55" & Bigger Frame TVs

    FYI: In this example, we’ve used 17×14 inch AV Back Box for 75 inch Frame TV installation.

    First, you need to locate studs inside your wall with a stud finder where you wish to mount your Frame TV.

    After locating studs in the wall, mark the outline (width x height) of the AV Back Box between 2 studs in a location where it will be completely hidden by the TV once the Frame TV is mounted on the wall.

    Cut and remove drywall where you’ve outlined, which should be the same dimension (w x h) of the AV Back Box.

    AV Back Box Installation for 50" & Smaller Frame TVs

    If you have a 32″ or 43″ or 50″ Frame TV, you could use 9×14 inch AV Back Box with slight modification. You just have to cut off a small nub with a mini hacksaw which takes only a minute to do. 

    Photos shown below are from our installation of 43 inch 2021 Frame TV with 9×14 AV Back Box installed behind the TV to hide One Connect Box as well as Rogers Ignite cable box. Although, space was little tight but they both managed to fit inside this 9×14 AV Back Box.

    Orientation of this 9×14 inch AV Back Box can be installed either long vertically or horizontally. If you install it long vertically like the picture shown below, make sure the AV Back Box is installed close to the stud on the opposite side of where the electrical outlet will be installed. *You need to make enough room for junction box (for electrical outlet) to fit inside the wall between the stud and AV Back Box.

    Now, you just need to cut off a little nub shown in the picture below by using a small hacksaw to be able to slip in One Connect Box into this 9×14 AV Back Box.

    The electrical outlet inside the AV Back Box will power the One Connect Box, which will feed power to the TV.

    As you can see in the picture below, One Connect Box fits into this 9×14 AV Back Box after cutting off a nub. You just need to slip it in from the side that you cut off the nub.

    For this installation, we also added Rogers Ignite cable box into the AV Back Box as well. It was a tight fit but we managed to put it in front of the One Connect Box and it was still flush to the trim edges around the AV Back Box.

    9×14 AV Back Box fits perfectly between the 2 wall brackets and totally out of the way. *FYI: Only 32″ & 43″ Frame TVs come with these small wall brackets. For 2020/2021 year models, 43″ & bigger Frame TVs come with full size One Connect Box and 32″ Frame TVs come with Mini One Connect Box.

    2024 One Connect Box dimensions are 13.7 x 5.4 x 2.6 inches or 34.8 x 13.72 x 6.61 centimeters which is same as previous 2018~2023 models.

    2024 Mini One Connect Box dimensions

    2024 Mini One Connect Box dimensions are 8.2 x 3.6 x 1.3 inches or 20.83 x 9.2 x 3.30 centimeters.

    *Only 32 inch Frame TV comes with Mini version.

    2024 Slim One Connect Box dimensions

    2024 Slim One Connect Box dimensions are 13 x 11.5 x 1.62 inches or 33.02 x 29.21 x 4.1 centimeters.

    Samsung’s 2021 ~ 2024 8K Neo QLED TVs come with “Slim One Connect Box” which is slimmer than regular “One Connect Box”. Although, it’s gotten slimmer, it’s wider now and shaped more like a square than a rectangle. 

    What size AV Back Box do I need to accommodate One Connect Box?

    For 55″ & larger Frame TV, we recommend using 17×14 inch AV Back Box because it’s easy to install the Slim Fit wall mount above these AV Back Boxes.

    For 50″ & 43″ Frame TV installation, we like to use 9×14 inch AV Back Box with slight modification (as mentioned above) since these TVs are not that big, it’s easier to hide the smaller 9×14 AV Back Box behind the TV.

    For 32″ Frame TV, choose 9×14 inch AV Back Box as it comes with much smaller “Mini One Connect Box”. Install the AV Back Box long way horizontally towards the bottom of the TV if possible.

    Tip: You should have AV Back Box installed very close to the bottom edge of the TV so it’s away from the TV mounting brackets as far as possible. As long as your TV can cover the entire AV Back Box when it’s mounted, that’s all it matters. 

    If need be, “Slim Fit Wall Mount” or “No Gap Wall Mount” can even be installed in front of the AV Back Box. You just might have to build some extra support behind drywall where it’s too close to the AV Back Box if there’s no stud nearby. As an example, you can use combination of 2×2 dimensional lumber with plywood behind drywall.

    Where can I buy AV Back Box for in-wall Storage?

    You can purchase AV Back Box for in-wall storage right on our website. We ship to USA & Canada.

    Frame TV Installation (2024)

    In regards to installation process, 2024 Frame TV models are exactly the same as 2021~2023 models. They all come with same split design 2 piece “slim fit” wall mount and same dimension of One Connect Box that serves as the main hub for all AV connections & network and also supplies power to the TV itself.

    As you can see in the picture above, 2024 Frame TV is installed in front of the AV Back Box in order to hide the One Connect Box behind the TV.

    Frame TV Installation (2021~2023)

    Since 2021, Frame TVs have gotten much thinner. Samsung also changed the name of the wall bracket to “Slim fit” wall mount from “No Gap” wall mount and new wall mount comes with 2 piece split design.

    Frame TV Installation (2020 & Older)

    2020 Frame TV models were thicker than 2021 models and later. This generation also came with “No Gap” wall mount which was a single piece bracket design.

    Difference between 2020 vs 2021~2024 Frame TVs from installation perspective

    In terms of aesthetics, the biggest difference is that the 2021~2024 Frame TVs have become noticeably thinner than the previous generation models, hence making it look much more sleeker when wall mounted. For example a 55″ 2020 Frame TV is 1.8″ in depth and 2021 ~ 2024 model is only 1″ in depth. That’s almost half the size!

    Besides the difference in depth, the only other notable difference is the different style of mounting bracket.

    Frame TV wall mount design changes

    Samsung has changed the mount design going from “No Gap Wall Mount” from previous gen to “Slim Fit TV Wall Mount” for 2021 & later models. 

    No Gap Wall Mount (2020 & older)

    “No Gap Wall Mount” came with just a single piece design wall bracket for mounting to the wall and single piece attachment on the back of the TV for hanging it on to the wall bracket.

    Slim Fit TV wall mount (2021 ~ 2024)

    For 2021 & later models, wall mount has been completely redesigned and it’s now called “Slim Fit TV Wall Mount”. 

    The new design comes with 2 separate pieces of wall brackets for mounting to the wall and 2 separate attachments that goes on the back of the TV for hanging them on to the wall brackets.

    Is there any improvements to the Slim Fit TV Wall Mount compared to No Gap Wall Mount?

    Since Slim Fit Wall Mount comes with 2 separate pieces of wall brackets, you’ll have a better chance of hitting at least 1 stud per wall bracket.  

    No Gap Wall Mount comes with just a single piece wall bracket, so chances of hitting 2 studs based on where you want to position / mount your TV is going to be very slim. 

    Either way, when you’re installing a Frame TV from any generation, it requires some extra fabrication to get it installed properly to make it look good. So if building some extra support behind Frame TV is necessary for mounting, that should also be done as part of the installation process.

    Other than being able to possibly hit 2 studs with the new Slim Fit Wall Mount, we don’t see any other benefit over the No Gap Wall Mount.

    It depends on which generation it’s from. But, generally One Connect Box includes following connections; 

    • 4 x HDMI (3 x HDMI + 1 x HDMI ARC/eARC)
    • 1 x Digital Optical Out (Toslink)
    • 2 x USB 2.0 Port(s) 0.5A / 5V HDD Port
    • 1 x Ethernet Port (Not included with One Connect Mini Box)
    • 1 x Antenna In (Not included with One Connect Mini Box)
    • 1 x One Connect Port
    • 1 x Power

    For more information, you can refer to Samsung (Australia) website to compare generation by generation. Please note that Australian versions are slightly different than the ones in USA & Canada. For some reason, Samsung USA & Canada websites don’t publish this information.

    How do I connect more devices to my One Connect Box in the future if it’s hidden behind the TV?

    Instead of worrying about possibly having to run more cables in the future, you can just run all the cables that you might need in the future at the time of installation. 

    Hence, it is strongly recommended that you run several HDMI cables at the time of TV installation even if you don’t plan on using any at the present time. That way, you’re ready to connect any new devices in the future without having to take your TV off the wall and fish cables later.

    You can pre-run any low voltage cables such as HDMI, Coax & Ethernet cables that are fire rated for in-wall application from your components location to your One Connect Box hidden behind the TV.

    Tip: It is best practice to install an innerduct (commonly known as “Conduit”) inside the wall, rather than having just pre-wired cables in the wall. Having an Innerduct in the wall is the ONLY true way to future-proof yourself so you can freely add / remove cables in the future when you upgrade your TV to the latest technology again and again. This is especially true if the TV is being mounted over fireplace or custom wall unit where it’s impossible or really difficult to fish cables later. Ideally, you want the inner-diameter of the conduit to be at least 1.5 inches.

    Can I Hide One Connect Cable inside a Wall?

    Samsung One Connect Cable included with Frame TV or QLED TV is not in wall rated
    Samsung One Connect Cable included with Frame TV or QLED TV is not in wall rated

    You cannot hide One Connect Cable that comes with the Frame TV or QLED TV as it’s not rated for in-wall installation. But there is an in-wall rated version available which is sold separately (albeit, it’s only compatible with very few models). 

    Samsung’s Frame TVs and higher end QLED TVs (7 series & higher models) from 2018 and later don’t have a standard power cord of its own that plugs directly from TV to wall receptacle. Instead, the power is actually supplied from One Connect Box to the TV through One Connect Cable.

    What is One Connect Cable?

    One Connect Cable is essentially a Power Cord with Fiber Optic Cable wrapped around together in transparent sheathing. Not only this cable carries AV & Data signals to the TV, but also carries power (voltage) to the TV as well. One Connect Cable that’s included with Samsung Frame TV or QLED TV is not certified for in wall application. Which means it’s against the code to hide it in wall.

    Samsung VG-SOCR86U/ZA One Connect In-Wall Certified Cable 5 meter / 16.4ft for QLED & FRAME TVs (2019) UL approval type OFNP FT6 (NEC, Article 770/UL 1651) USA and Canada

    Samsung VG-SOCR86U/ZA One Connect In-Wall Cable for QLED & FRAME TVs is certified for in wall application. This cable can be purchased separately but apparently it’s only compatible with very specific Frame TV & QLED TV models.

    One Connect In-Wall Certified cable has an extra layer of thick FT6 rated white jacket that wraps around the One Connect Cable that ends with “cord grip fitting” at the end of the white jacket on both ends of the cable.

    FYI: Generally, power cords of any kind are prohibited from being hidden or buried in wall. But this specially designed One Connect in-wall cable (which also carries power) is certified to – UL approval type OFNP FT6 (NEC, Article 770/UL 1651) USA and Canada. Hence, making this cable safe to be hidden in wall.

    In Depth

    According to NEC Article 400.8 in USA & CEC Article 4-010 (3)(a)(ii) in Canada, they both state that “Flexible Cords” (referring to power cords) cannot run through holes in walls, ceilings or floors.

    The reason behind this is because power cords are considered to be fire hazard if hidden inside a wall. This building code applies to almost everywhere in USA & Canada. And building codes exist to protect people from any potential accidents such as electrical fires.

    Samsung (US) website shows following list of TV models that are compatible with One Connect In-Wall Cable;

    • QN98Q900RBFXZA
    • QN82Q900RBFXZA
    • QN75Q900RBFXZA
    • QN65Q900RBFXZA

    • QN55LS03RAFXZA
    • QN49LS03RAFXZA
    • QN43LS03RAFXZA
    • QN85Q900RAFXZA

    If your TV is listed above, you can purchase this One Connect In-Wall Cable on Amazon.com (US) or Amazon.ca (Canada) and hide the One Connect in-wall rated Cable in wall and place the One Connect Box elsewhere away from your TV within the cable’s reach.

    If your TV is not listed above, you will need an AV Back Box for in wall storage installed behind the TV to hide the One Connect Box & One Connect Cable behind the TV since the One Connect Cable that comes with your TV cannot be hidden in wall.

    As you can see in the photo above, the In-Wall Certified version of the One Connect Cable looks quite different than the one that comes with the Frame or QLED TV.

    In-wall version of One Connect cable is quite thick. It’s little over 1/2″ in diameter. So any excess cable needs to be carefully coiled into the wall to install the wall plates for it.
