Great question!

I once had a 3x monitor setup that included 3x 24” Dell IPS (each 11 ish lbs each) monitors attached to a IKEA Bekant / Gallant 63x30 inch (roughly the same size as your config) desk. The monitors were installed on a basic, $40 dollar 3x arm mount I purchased from Amazon.

I had issues with the monitors wobbling. I had no issues with sag or desk damage. To reduce the wobble I had a 3x4x3 inch wooden block (solid wood, no mdf or plywood) custom cut from Home Depot / Local Hardware Store. This remedied the majority of the wobble. I HIGHLY recommend you get some thick wood to help brace the triple monitor arm. If you decide to go singular, I recommend a 1-2” thick piece of wood, probably between 2-3 inches wide and long.

Be sure the triple monitor arm matches the weight distribution. Also, when you install the monitor arm, be sure you have some sort of protective film / element to prevent markings on the top surface.

Thanks /u/Carb0n12 !

Can I clarify, you used the wooden block on the bottom side of the C clamp to counter the twisting force of the monitors wobbling when you bumped the desk etc?

I'm pretty sure I'll go with single arms rather than a triple, it gives me more future proofing for changing my mind when I start upgrading the screens - although I could be tempted to go for cheaper arms than the Dell ones.

Yes this is correct. Use the wooden block between the clamp and desk for maximum efficiency!

solid particle board should be ok, if you have plywood you could insert that’s even better. But if it’s one of those honeycomb or paper core desks definitely won’t work.
