A: Regrettably, we are not familiar with the specifications for the Secretlab MAGNUS Monitor ARM, and do not know what VESA Mount Patterns it supports, but the LG 39-inch UltraGear™ OLED WQHD 240Hz 0.03ms G-Sync Compatible 800R Curved Gaming Monitor with webOS, Model # 39GX90SA-W, is a VESA-compliant display with a 100 x 100 mm VESA Mount Pattern that can be used to mount the monitor on any VESA-compliant Monitor Arm that supports the monitor's VESA Mount Pattern as guaranteed by VESA Compliance. Check the specifications for your monitor arm to see if it supports the monitor's VESA Mount Pattern. The monitor also has a weight of 16.1 lbs without the stand, a width of 34.9", and a height of 15.9", so you will need to check the specifications for your monitor arm to see if it can support the monitor's weight or it's width or height, depending on whether it is a vertical monitor arm or horizontal monitor arm...^Ivan.

The monitor has a great picture on it. Much like the previous model 39GS95QE-B.AUS. WebOS is ok for my first time ever using it. Although WebOS has more features and functionality, I think the settings in the previous model were easier to use and find. My biggest issue is I cannot get the monitor to go in standby mode and do a pixel clean on its own. Contacting LG was no real help as they initially told me it didnt have a standby mode. I had to take images and show the guy it did. Every time it has inactivity, it says no input, attempts to go in standby and then comes back out and starts the no input again. This is the same across three systems. I even tried to turn off the network on the monitor and unplug the current selected input to see if that would help. It did not. I had no issues with the previous model going in standby and cleaning itself. Hopefully they get this fixed soon.
