I myself had to send the arms back because I had to push my table too far forward. But I had 2 monitors horizontally, one straight in front of me and one diagonally from the left. I don't know about you, but if you want to be absolutely sure, I would look for another monitor arm.
You can see this in the technical data sheet which can be found under the specifications:
https://www.digitec.ch/Files/3/3/6/7/2/9/0/4/datasheet_IB-MS314-T_d.pdf
The arm can hold a maximum of 8 kg, which means that your 10 kg monitor is too heavy. It is recommended not to exceed this weight to avoid stability problems.
Yes, you can hang a monitor upright, as the IB-MS314-T monitor mount allows a horizontal rotation of +/- 90°. This means that you can use the monitor in both the usual landscape and portrait position.
The monitor cannot be freely rotated by 90 degrees. Rotation is limited to +/- 90° horizontally and +/- 45° vertically, which means that a full 90° rotation is not possible.
Hey!
No, you will not (should not) have any problems. I also used it with only one monitor for a bit.
As you see in the picture it has this flat surface that goes under the table and the one above and this really helps in distributing the weight onto a larger area, compared to these "weaker" circle like fasteners.
I, personally, prefer how they do it here with this flat surface and can highly recommend them in general.
I personally assume a payload per arm.
Long version:
I use the mount with two AOC CQ32G3SU/BK monitors. These have a specified weight of 8.15 kg (with stand).
As I have not weighed them separately without the stand, I still estimate that they weigh 6-7 kg.
So there are easily 12-14 kg on the holder and it holds. The mechanism also works and the positions are retained (no tilting or pulling down). I have also been using the bracket since April 2022.
The manufacturer's website states "screens weighing up to 8 kg", which I also interpret as "per arm".
The price difference can have various reasons, higher purchase prices for smaller quantities or additional import costs. Every supplier offers different prices, so there may be price differences.
The mount works well with fairly light standard desktop type screens. I have a 27" aoc on it, it works pretty well but there is a bit of play in the VESA mount (Tilt left right).
I would recommend an ergotron for screens larger than 27" and especially with a heavier weight.
Yes, you can turn it vertically if the screen is not very wide and there is space from the middle of the screen to the bottom of the table, max 35 cm, so for a screen with a width < 70 cm it should be just fine, but you still have to look at the weight.
My 34'' Samsung screen is just over 70cm and I can't put it vertically (I don't need to and it doesn't make sense for such big monitors, otherwise you need a ladder to see the upper half :-) )
My dell 24'' screen, however, I can rotate and set vertically without any problems.
Details of everything included with the product can be found in the official manual available on the manufacturer's website ("Download & FAQ" tab): https://icybox.de/en/product.php?id=267
The maximum extension seems to be 450mm.
https://www.youtube.com/watch?v=6mfIBJHCY-s According to this YouTuber, there are two different mounting options available. The option with the table hole drilling is suitable if you want to place the bracket a little more centrally, so the table can be placed closer to the wall.
I mounted the Icy Box without any extra protection, which was not necessary, it already has its own protective rubber. The thickness of my office desk is 18 mm.
Yes, the arms are attached to the base during assembly and then secured with a grub screw. If only one arm is attached, you will see a piece of bare metal at the base.
You can either tighten or loosen the spring tension directly behind the respective joints with a slotted screwdriver. The weight of the monitor plays a role here, as the spring tends to pull upwards.
I did this by mounting the monitor and "playing" with the spring tension.
