    What is the maximum thickness of a desk that the bracket (lowest piece) can fit around? The top of my desk is exactly 2" thick. Would that bracket fit around a 2" tabletop?
    A shopper on Nov 30, 2016
    BEST ANSWER: Hi, the clamp on this mount opens to a little over 1.5 inches, so it won't fit the 2" tabletop. You could check out the following mounts that could all work with a 2" desktop: Product #s: 5402, 7562, 16245, and 15526. Thanks.
    I cannot use a clamp style. Can this be installed as a drill through?
    David S on Feb 1, 2018
    BEST ANSWER: It's not built for that. You would have to manually modify it significantly to mount it like that. It would probably require power tools and the handyman skills to do it.
    What is the diameter of the post? Would like to install on a shelving rack. Thx.
    A shopper on Jul 14, 2017
    BEST ANSWER: Hi, the diameter is 25mm or almost 1". There is a link to a document that shows the dimensions towards the bottom of the product page if you need to look up other dimensions. Thank you.

    This mount is awesome. I have a BenQ 24 inch monitor that came with a basic pedestal that only allowed for minor forward/back movement(tilt)... Since I have such a high office chair I decided I needed a mount. I was looking to purchase an Ergotron LX Arm Deskmount when I came across this one.

    I have been purchasing cables from usb to HDMI and everything in between for years here on MonoPrice. A buddy of mine even purchase a wall mount from here for his 40 inch Samsung LCD. Well I was looking for a similar TV mount for a 32 inch Sony for a friend of mine and saw this one. I decided to take the plunge since I was ordering a new set of wires for a new home theater install I was doing(re-doing).

    When I received the desk mount(overnight shipping was great!). Only $32 from Cali to Jersey. It felt like it was almost industrial, the weight of this thing felt as if it contained hydraulics or something. Anyway, I was excited and opened it up only to find out that although MonoPrice tried to included mounting hardware for any type of install my particular monitor requied longer M4 bolts just shy of an inch in length. So I went to the hardware store and picked some up and now I have an articulating desk mount that feels like it was made to cost $200+ dollars. I have never seen the Ergotron LX Arm but I couldn't imagine it being much better than this one from MonoPrice.

    Since I noticed they added this new feature on MonoPrice I also took some photos so you can see how it looks.....

    Great stand...modded
    My desk doesn't have a lip, but I needed a new stand for my displays. So I took a chance and ordered this unit.

    First thing I did was remove the clamp. There are four very small screws (I forget the size off hand, 4x46 maybe?) that hold the clamp to the post. The post and base are both hollow. I went to (insert DIY center here) and found a washer that is the same diameter as the post base and drilled out the four holes for the screws. I then put a bolt through that, drilled out my desk, and used a nut and washer on the bottom. To protect my desk, I cut a rubber mat I had and placed that under the post. It also helps with vibrations.

    All in all, it took me about two hours to mod the post and mount it on my desk. I've had it for about two weeks now and am absolutely delighted with it. All the parts total cost me about $40 including shipping and the ratchet extensions to reach all the way through the post. The closest analog that I can find with a grommet mount is about $150 or so from Amazon. So...VERY good deal. I'll be ordering two more for my other displays.

    Oh. And yes. I suspect I have voided any warranty on this mount. -)

    Some missing measurements

    Some missing measurements:
    Mounts to tables up to 4cm thick and the clamp part is 7cm long by 6.6cm wide , which means it won't work on desks like IKEA MELLTORP or TÄRENDÖ. For thick tables probably look for 5402 (no portrait position I think) or 7562 (more expensive and assembly required).
    Weight: 2050g + 200g for the mounting plate

    I can't comment on whether the monitor will sag since I support it with an empty bottle. For $25 there isn't really much to complain. "3-way adjustable" gives good flexibility, I pull it out to use and stow it back when I'm done.

    PROS: Comes fully assembled

    CONS: Allen key required to make adjustment (so don't lose them)
    Doesn't mount to thicker tables
    September 10, 2016
    Things I like:
    Good range of adjustments
    Arm itself is sturdy
    There is a ball joint on the back of the monitor clamp that allows rotation between portrait and landscape, and tilt up/down (my last arm didn't have tilt and it was very frustrating)
    Excellent price

    Things I don't like:
    Arm is stiff to adjust. It holds its shape pretty good, so it won't bounce around when you type, but don't expect to be moving things around with one hand - you need to apply a good amount of pressure to move it.
    The actual clamp is weak, and inconvenient. There are two bolts, but they don't have that large of a contact area. I tightened them, and bent the C-clamp doing so. They have rubber caps, but the bolts pierce the caps when you tighten it. There aren't knobs to tighten them, so you need to crawl under the desk with the supplied allen wrench to tighten them.
    I tightened them to the point the clamp was slightly bent, and still they didn't hold very well... pushing back on the monitor, when the arm was halfway extended, caused the clamp to slide off the back of the table instead of the arm bending.

    I ordered one, and ordered a second one for my dual monitor setup. I plan on drilling two holes about 1/2" in diameter and 1/2" deep into the bottom of my desk, and screwing the bolts into there. That should fix the sliding, which was the only weak spot. As long as you secure the C-clamp when bending the arm, you should be fine. If you want something where you can set the monitor to a comfortable level and it will stay put, this is the arm for you. If you plan on moving the monitor at the regular basis, the arm is too stiff and the clamp is too weak and you'll end up in trouble.

    PID 6421 Desktop Bracket Mount
    I am using this bracket NOT to hold a display monitor but to hold a small monitor speaker!

    Specifically an M-Audio AV40. I bought just one to "experiment". I didn't know if its head, the part that is supposed to connect to a display monitor, could be converted to a platform. Well, it happens that this thing is easy to disassemble and the head can be fully removed. You end up with a screw that can hold a horizontal platform. I cut a small wood platform (6.5" x 8"), put a hole in the center, and I used the original screw to screw it to the bracket. The final result was great! I can move the arms of the bracket to better position the speaker but since the speaker is kind of heavy, it will not stay leveled so I found a position that has its gravity center around the main silver arm, so that now the speaker is completely leveled.

    I painted the platform in black and used four sorbothane feet to hold the speaker firmly into the platform. I was very satisfied with the final result and then I bought a second bracket for the other speaker. You can find a picture of it at "www dot dpvqb dot com slash bracket.jpg".

    PROS: - can be easily disassembled for alternate use

    - looks nice

    - seems durable

    CONS: - the two screws that hold it to the table top are not the best solution

    640mm is not the max height. The maximum height I can achieve from the surface of my desk to the middle of the VESA bracket is about 51cm. I'm a bit disappointed that I'm missing 5" but otherwise it's a very solid, sturdy product.

    Very impressed with the build quality you get with this stand at this price. It costs less than the little square aluminum VESA adapter plate I had to buy from Apple! Heavy. Does NOT feel cheap. I bought it for my 17" Apple Cinema Display that I use as a palette monitor. Swings smoothly and firmly side to side. Thanks to its solid metal, rubber padded clamp, it does not have the problem of sliding down its post that I have encountered with other stands.
    Highly recommend.

    PROS: Solid.
    All metal construction.
    Nice looking.

    CONS: None.

    Monoprice 6421 monitor mount
    Very good desk mount for monitors. Has 2 VESA mount sizes (75 mm and 100 mm). Fits my ASUS and Dell 24" monitors perfectly. Saves space. I thought I'd have a problem with my particle board desk, but monitor mount works fine. I bought one and liked it so much, I bought another identical mount for another monitor. Saves space and works much better than a monitor stand.

    PROS: Very adjustable stand. I'm a college student and have a small desk. When I need to read, I simply push monitors back to make room for my books.

    Incredibly sturdy, but for thinner desks only
    This thing is solid, and looks heavy enough to support near the max weight, but unlike the 5000 models the desk clamp can't really open past about an inch and a half. (On this model the clamp is a single piece, so you can't rearrange it.) Looks like I'll have to return... too bad, since the 5000 ones apparently don't rotate.

    rotate/tilt is awesome, clamp stinks
    i bought this and the 5402 clamp to mount two monitors. the clamp on this one is not as nice as the 5402, the 5402 has a wider clamp and it uses a vise to secure it. the 6421 uses 2 big bolts which creates pressure points and a fulcrum when you have a monitor mounted. i really need the 360 rotation and the tilt is a lot easier to manage on this one then the 5402
    i also read that mounting a monitor in portrait was easier with the 6421 then the 5402.

    i really wish monoprice would include better pictures of the clamps so you can see the different kinds. i'm pretty sure the mount is secure but it's uneasy seeing the clamp deflecting with the monitor mounted.
