question

I want to get this LX Dual Side by Side Arm for 2 Eizo 24 monitors.It seems to be good height. I am more worried about extension. I have a diagonal/radius corner desk, with my main monitor in front of the corner (so plenty of room behind monitor). My secondary monitor is angled to the first on a part of work surface which is only 24 deep. I don't want the monitor too far forward on that surface - about 13 from front of desk is good. Seems that is possible and one just has to play with placement of the grommet mount to get the most flexibility. Do you agree?
Asked by: Barbara
I concur.

I have 2 LG UltraFine 27MD5KL-B 27" 16:9 5K IPS Monitors that I want to mount to this arm. Can interface these monitors to this arm without additional accessories or do I need to get something to connect these to this arm?
Asked by: Rich
The system works great, just think what your doing before you do it.. The monitors are heavy so you have to set the tention on the arms before you put the monitors on them.Light enough to support the monitors, but easy enough to move the arms to mount them.. The monitor brackets are lined up with four thumb screws, just stand-up the monitor to do this. Then make the tension stronger so the monitor won't fall over. Adjusting the tention takes playing with to make it right. If your monitors are to heavy to handle, get some help holding them up. These arms are in a lot of the stores around here. Just take your time doing this...
