Thingy Club Gas Powered Fully Adjustable Single Arm LCD LED Monitor Desk Mount Bracket Stand For 10-27" Screens with 45° Tilt & 180° Swivel + (USB | Headphone | Microphone) Extension Sockets

40" curved Samsung 4K UHD (from 2015) weighing 8.1KG, that uses a VESA200 (this arm does VESA75 or 100 only so I also bought "200 x 200 VESA Black Mount Adaptor Plate by Electrosmart" to convert the 100x100 on this arm so I could attach the TV. I also needed a couple of screws and washers to attach the converter plate but I had those lying around)TV was originally on a curved base taking up all my desk. I wanted 9cm of clearance from desk to the bottom of the TV to fit my centre speaker I also wanted to ensure it wasn't going to end up a foot off the desk, the original stand only gave 7cm so the speaker was behind which looked naff.I also wanted my desk space back and to be able to physically move the screen back as far as possible on the desk. I was governed by the bulk and shape of the original mount. *85cm wide, the legs curved out toward the front and was approx 15 cm deep. all space I couldn't use.)Results:---------------------------------With some adjustments to the locking tension nuts after assembly this hold my tv perfectly (its not an easy one man job).NOTE: there are three on the VESA plate, so if it tilts forward too much, make sure you get the 3rd one (I could only see two as the arm blocked view of the third!)No one has mentioned potential clearance range between the desk and the TV (or max height with TV installed) as it will be TV dependentWork it out as follows. The arm from desk to the centre of the TV's Vesa mount when set to it highest setting is 51cm.Once you've measured your TV itself from the bottom to the centre of it's VESA mount (on my Samsung it is dead central), you can work out the difference by subtracting that from the 51cm. The minimum in my case for my TV as its so big means I can have the bottom of the TV flat to the desk if I wanted to. The most clearance I could have is around 18cm.At the back of the desk (depending how you set it up with the arms) and which way they point is 2.5cm so you can't have a desk flush to the wall. Not an issue for me but a note worth considering.I gambled on this arm fitting such a big TV but as MAX weight is 9kg, my TV is 8.1kg and I needed to take into consideration the weight of the VESA convert plate. I'd guess my total is around 8.7kg.I love this it's built well, easy to move TV once it's all connected, the desk clamp is sturdy and this holds my TV rock solid. Wanted to run it a few weeks before posting a review but it hasn't moved an inch. Highly recommended. It is expensive for a single arm but that moeny is worth it all day long for what you get and gives me back 30" of my desk I couldn't use (and mean I can push the TV back another 5" which when you sit that close to a 40" panel has made all the difference in FPS and fits my peripheral vision perfectly.Didn't realise at the time it also has headphone, mic and USB extensions on the front of the Clamp.Tested the USB just for this review and it takes usb3.0 no issues. Wiring on the headphone and mic is thick enough and will do the job but I wouldn't use it on a daily basis as it adds extra cables on the desk which I can route underneath with extensions for a much better, clean look.The ONLY minor on this whole thing is that USB 3.0 port - I wouldn't want to plug things in and out of it repeatedly as the port itself its really quite wobbly from the outset. It works for sure but for how long I wouldn't like to say. Maybe it's just mine.Installation tip:If its a big TV the arm will fight you when trying to screw in the VESA mounts - its set pretty stiff out of the box. It will be at max height and can only be compressed when applying force to compress it. As I was doing it on my own and didn't have three pairs of hands which is what you need I got around it like this:Oddly it was best to keep the tv on its original stand. If you decide as I initially did to place two pillows on the desk, put hte TV face down on that, then attach the arm,. when it comes to making the whole thing vertical its difficult to manage and the likelihood is you'll damage drop or scratch it). even if you get it upright all he force wil be on the arm as you try to stop it waving about making positioning onthe desk nigh-on impossible as well as then trying to hold it there whilst you tighten the clamp to secure it to the desk). That has disaster written all over it.1. Build the arm as per the instructions (fairly clear with a little trial and error depending on the attachment method you desire - clamp or extra bits supplied are required kit comes to allow you to drill holes through the desk and use the metal plates to attach the arm through those for a more permanent solution. I used the clamp which is the easier of the two and allows for it to be moved if required at a later stage. My desk it 18mm thick so structurally is think enough to hold it via the clamp method)2. Secure the arm via hte clamp to the desk firmly and in the place I wanted it.3. Place Tv in front of desk-mounted clamp arm off set to the left (or right depending which way you've set the arms to be. Squash arms and attach opposite corners of the vesa. TV will be heavy enough to prevent it being lifted up.4. Attach other two opposite VESAs so all four are now fixed.5. Undo screws on back of TV stand but leave the TV balanced on it. Now lift the TV (which leaves the base exactly underneath to hold it should you need to lower it again.6. Whilst off the desk adjust the arm screws for tension, do height first. I had to rotate to the + sign MANY full rotations times (many more than you'd think) for it to make a big enough difference.7. Once the TV holds itself, then do the tilt (note there are three allen keys to be tightened, you may only see two as one may be hiddet by the arm itself), You may have to move the now attached tv at weird angles (breathe deep and get it done quick). In my case I had to tighten all three fully the ease the bottom on off about half a turn. Works perfectly and tilt adjustment although stiff is possible. As my use is static I won't need to change it anyway now.Briiliant for my needs, solves all my issues although I had to be creative due to the 75&100 VESA options and my Tv being 200 VESA but all components came in at under 9kg for which this arm is rated.NOTE: if you have the arms running parallel to the back of the desk and want hte TV pushed back as far as it will go (as I'm using it in another the pic I've attached) the tv will not sit central on the arm and will look offset (also see close up pic of the base attached). The only way you could have the tv central on the arm is to have the arms poking straight out the back meaning your desk would need to be about 18" from the wall (maybe more) depending on how high you have the monitor set. The lower the TV/monitor is the more bend in the arm there will be and the bigger the distance to the wall is needed.

Great arm. The USB and audio jack are a neat addition I didn't need, but I'm not one to turn down extras! The arm itself extends well into my room, allowing me to view it comfortably at my desk and then position it far enough out that I can watch movies and TV in my bed. When I'm done, the arm can be positioned back easily and solidly to where it came from. Easily the best monitor arm I've used, professionally or personally.

Exceptionally well designed, allowing me to effortlessly move the monitor around throughout the day which I do regularly as I change my posture. It's expensive for a monitor arm but you can really see where your money has gone - this thing is really sturdy and high quality.

the arm looks a bit cheap and the ball joint give out fairly fast on it

Very good quality, can handle quote a large monitor, easy to adjust and set up.

Exactly as described very good.
