Would I be able to use this for a 34" in the center and 2 27" on the sides? It looks like 3 31" screens would be about 80in wide, and 34" + 2 27" would be about 78in

The Mount-It! Triple Monitor Mount is designed to hold three monitors up to 32 inches each. It might not be suitable for a setup with a 34-inch monitor in the center and 27-inch monitors on the sides due to the size limitations and weight capacity per monitor.

Could I position the monitor mount so i have two at eye level and the third goes up above the middle monitor by lowering the middle mount and raising the right one above?

The Mount-It! Triple Monitor Mount allows for height adjustment and full motion design, which lets you tilt, swivel, and rotate your screens as needed. This suggests that you could potentially position two monitors at eye level and the third one above the middle monitor by adjusting the height and angles accordingly.

would this work with a 37 inch and a set of 27 inch displays surrounding it? i realize it says max 34 but is that just where the screens wouldnt fit next to each other?

The Mount-It! Triple Monitor Mount is designed to hold monitors up to 32 inches in size. Using a 37-inch monitor along with 27-inch monitors may not be ideal, as the mount is not specified to support a monitor larger than 32 inches. Additionally, the larger monitor might not fit well alongside the 27-inch displays due to space constraints.

How stiff are the connections between each segment? Can you adjust the tension of each rotational axis the way you can adjust the up/down tension?

the tension on each arm is adjustable
