TV Display mounted to wall with Onkron M4 arm

Features & Specs Review of Onkron M4 Articulating Display Wall Mount

Mounting your television to your wall is a great way to save space and make a cozy man cave. You can position the TV screen in a high position, allowing you to sit back & recline, hands behind your head, watching whatever movie, TV show, or YouTube video that you want. Sitting back may also be a desirable posture while playing video games, allowing you to relax all of your body, putting less stress on your arms while you recline in your chair.

So yea, wall mounting your flat screen television or monitor could be pretty useful. But in order to mount your television, you need a good wall mount. Might I suggest the Onkron M4W Universal TV & Monitor Wall Mount?

This wall mount comes is a very compact form factor made of cold-rolled box section carbon steel that is very rigid and tough, being able to take a maximum load of 77 pounds. The wall mounts achieves its compact form factor by being able to fold on itself, leaving the flat screen TV hovering on the wall by 2.2 inches. In this way, the wall mount gives a house a “modern” look, because in the past televisions were not normally wall mounted.

The wall mount can also unfold and extend out the display a full 19.7 inches forward. Moving the screen closer to your face may be desirable to increase the immersiveness of a movie or video game.

So there are 2 models of the M4 Onkron display wall mount: the M4-WHT or M4W and the M4-BLK. The only difference is that the first one comes in a white color, and the second one comes in a black color.

The wall mount comes with a high quality 6ft 1080p HDMI cable, a bubble level, and a wrench to help put some of the parts together. It also includes all the screws, washers, bolts & anchors that you could need to install the wall mount on drywall and 2-by-4 studs.

Cold-Rolled Box Section Carbon Steel

Cold Rolled

What is cold-rolled box section carbon steel? Well, “cold-rolled” refers to when a metal’s shape & structure are altered at temperatures below steel’s recrystallization point, near room temperature in other words. The benefit of cold rolled steel is that it has a higher tolerance compared to hot rolled steel, and is less malleable and thereby less prone to deformation.

Cold rolled steel is made in a process at temperatures close to normal room temperature. Cold rolling increases the strength of the finished product through the use of strain hardening by as much as 20 percent. Cold rolled steel is more dimensionally precise than hot rolled steel. Cold rolled is more durable & tolerant.

Box Section

“Box section” refers to the fact that the structural arm of the wall mount is made of box sectioned steel. Box sections refer to steel that have a square or “box” cross section that is hollow inside. The hollow allows you to reduce the amount of steel used and the weight of the steel product. And the box shape of the cross section improves the structural strength & torsion resistance of the steel.

Carbon Steel

Finally, carbon steel is a type of steel that has up to 2.1% of carbon by weight. Iron all by itself is quite ductile, soft, and easy to malform. So carbon is added as an alloying element to iron to improve its tensile strength (resistance to tension & compression).

In pure iron, the crystal structures have little resistance to iron atoms slipping past one another. This makes pure iron quite ductile, soft, and malleable. In comparison, steel has small amounts of carbon & other elements included with the iron to make the crystal structure more resistant from atoms to slip by one another. This makes steel harder and stronger than iron, and less malleable & ductile. Which is desirable for the M4 Onkron wall mount for improved load bearing capabilities.

7 Bolt Holes for Wall Bracket

The plate or bracket that attaches to the wall has 7 bolt holes to allow for the insertion of thick load-bearing screws. There are 3 bolt holes on top, 1 in the middle, and 3 bolt holes on the bottom. These are a sufficient number of wide holes for enough bolts to support very heavy loads up to 77 pounds. These well-placed holes also insure that the mount stays firmly secure onto the wall, leaving no space for wiggling.

And you don’t have to use them all; for example, in my living room there was a flat screen television weighing about 20 pounds that my dad wanted to wall mount. And he didn’t want to make too many holes in the 2-by-4 behind the drywall. So he ended up only needing to drill 3 vertically aligned holes, one for the top, middle, and bottom of the bracket. This way, we didn’t have to worry about the structural integrity of the 2-by-4 being compromised with too many holes concentrated in one area. And 3 bolts was more than enough to bear the load of 20 pounds.


Forward Spacing

The M4 Onkron wall mount has the forward spacing of 2.2 inches close to the wall to 19.7 inches extended away from the wall. The 19.7 forward extension is useful because sometimes you might want to bring your TV or monitor display up closer to see what’s on the screen clearer or for better immersion in movies or video games. And sometimes you might want the display out of your face, so you have the option of putting the display almost flush against the wall, making the display almost appear as if it was “hovering” in the air.


The M4 Onkron TV wall mount has a swivel range of 180 degrees. That means you can change the horizontal angle of the display within the range of 180 degrees in any direction away from the wall. Whether it be to the left, the right, or straight ahead.


The m4 wall mount can also be titled up 5 degrees or down 8 degrees. That means the display can be placed somewhat high and fit the viewing angle by tilting downwards. Similarly, the display can be a little lower than usual and fit the viewing angle by being tilted upwards. For a straight-forward looking angle, you can simply leave the display without any tilt at 0 degrees.

Cable Management

In total, the m4 Onkron wall mount has 4 plastic covers to manage your wires & cables. Without these plastic covers, the wires connecting to your TV display would droop out quite unattractively. So to remedy this, you can simply run your wires through the plastic covers.

Installation Instructions

I quickly went over the installation & setup of the Onkron M4 wall mount in this video:

But here are the exact wall mount installation instructions in text, if that’s more your speed:

So for installing the Onkron M4W wall mount, you first need to find a non-load bearing stud to screw the wall plate into. If there are no studs, the M4W wall mount comes with anchors that will allow you to install it into the drywall alone.

Once you have found it, you may need to manually make small holes through the drywall with a needle like instrument to detect the exact location of your stud. The reason you do this, is because you do not want to drill a bolt hole near the edge of the stud & cause it to crack apart.

Then you take your wall bracket and the included bubble level to decide the locations of the next bolt holes; the bubble level will insure that your mount doesn’t hold the display in a crooked angle.

After marking the places where you will be screwing in bolts, go ahead and drill a small guide hole in those locations. And then get a bigger drill bit that is slightly smaller than the size of the bolt. We found that a 3 by 16 inch drill bit worked adequately.

We then got a 15 by 32 inch hexagonal head to tested if the bolt went into the holes without any issue.

Furthermore, you’ll notice that we only drilled 3 holes; 1 in the top, 1 in the middle, and 1 in the bottom. This is because we were drilling into a 2-by-4 stud; drilling too many holes to one area would weaken or even risk cracking the stud hidden behind the drywall. Also note that only using 3 bolt holes was sufficient for us, because we were mounting a 20 pound flat screen TV. A heavier load would require more bolt holes to be used for a more secure mount.

Note that you can control the tilt of the display by loosening the top bolts behind the front plate, changing the tilt, and then retightening those bolts.

Also note that you should first unscrew the front plate from the wall mount and attach the front plate to the display. Then you should be able to place the plate on the mounting arm’s circle lip. The circle lip goes into the keyhole shaped hole, in the big circle, and then sit & lock into place in the smaller half-circle. And then you can screw the front plate back into the mounting arm to secure it all together.

This way, you can technically mount your display all by yourself. But it doesn’t hurt to have someone to hold everything in place, just in case. You’ll notice we skipped this step and directly screwed the TV onto the wall mount.

Also, there are long black plastic washers you should use when attaching the front plate to the display.

And that’s it! The display is now mounted onto the wall. You’ll notice it looks very nice close to the wall. And is also nice to use occasionally full extended when you want to make the movie or video game you are watching more immersive. You can also swivel the display to the left or right for your viewing pleasure.
