Question: Could this handle 1 Dell U3014 and 2 Samsung 233T or 1 more Dell U3014?
Document: Bought this as it is one of the few stands that are supposed to work with 24&#34; monitors, and for the most part it does. I have 2 Dell U2412Ms and a 2410WFP on the stand.Here is a list of the problems...- The bolt that clamps the arm to the stand is about 1/8&#34; too short. If you end up purchasing, do NOT unscrew this as it is difficult to get back in.
(But than again, you probably dont have 3 monitors on the average desk) I would have like a better locking mechanism to attach the monitors to the arms. They kind of just float there and accidentally dropped my monitors off of the stand a few times. Adjusting the height and monitors is not easy, so like the previous commenter said, hopefully you really only have to do it one time. I have 2 Dell standard 21 LCD's but have 1 Dell 23 LED screen.
I purchased this stand a week ago and received it today (good speed for free shipping to Alaska).Setup was easy, materials are solid/durable.i was ecstatic to find a stand of this quality for this cheap (purchase price at the time was $209) its a great match for my 2x21.5inch viewsonic monitors + 1 Samsung 21.5inchI will update this short review if anything unfortunate happens or i find an error in the stand.
I use mine for 3 23&#34; LCD Samsung monitors - your experience my vary depending on the size of monitor. This stands appears to be able to easily adjust to smaller sized monitors, my setup placed the two side monitor near the end of the outer arms for the angle I desired.Lets clear up others comments about this stand.1). Assembly - very easy. You are provided two Allen wrenches, three vesa brackets, the base and the steel tube.
It includes 3 clips - 1 for the mast and 2 for the arms. 4 for the arms would have been greatly appreciated, as there is 4 sections of arms. I had to end up using some zip ties which is fine because you  can't see them behind the monitors in my setup - if your monitors face out you would likely prefer more of the clips for aesthetics.Overall, I would definitely recommend this to others.
Bought this to hold up 3 24" Dell U2410 monitors for eyefinity and very impressed. Looks very clean and the stand its self is very sturdy. Installation in easy but can be tedious to get all your monitors lined up properly. Total instal time is about 2 hours from opening box to finish. If you have a multi monitor set up you must buy this ASAP
I ordered this stand after ordering and returning other products because they could not support three 23" Samsung monitors. This one does with a little room to spare although at this size, there is some limit to the angular adjustment on the wing monitors. This setup provides adjustments for tip, tilt and height as well as the angle of the side/wing monitors.
Sturdy and level. I use 1x24&#34; and 2x21&#34; displays. I'm about 6' 1&#34; and when I set per all ergonomic guidance, I wish the stand could go about 1&#34; taller.
On this stand (the 100-D16-B03), the center bar is 26.25&#8243;, and each swinging side wing is 13 1/8&#8243;. With the monitors mounted at the very ends of the wings and tilted so that the bezels overlapped, the most I could possibly manage to swing them in was about 20 degrees.
Wow - as others have mentioned this is a big setup. I went with 20in Dell Flatscreens. I have a big desk so the size isn't an issue.All in all it was pretty easy to put together. The only problem was the the mounts needed to be adjusted so the monitors all were level. The included hex wrench was useless as whomever at the factory put this together with a power tool & over torqued the bolt beyond what a person could reasonably manage without a ratchet wrench set & my hubby's muscles.
Answer: I doubt you will be able to squeeze all that onto this triple stand.  I have three samsung 23" and the outer two monitors are only 1 inch from the end of the rail.  The Samsung Monitors I use are 22" wide. I could not image how two 30" would ever fit.I suggest you visit the Ergotech site and check out the next size up version. http://www.ergotechgroup.com/product-categories/apex-series-ultimate-multi-mount-56/
