yes - I have mounted two Samsung Odyssey G5-G55T 34" (curved). However, 34" is the maximum - the arms have to be horizontal and therefore the mount has to be drilled almost correctly in height. The strength of the gas pressure spring can be increased using an Allen key (included in the delivery package) and the weight is therefore no problem.

Yes, but if you try to raise the monitors, they come back down by themselves because they are too heavy.
