Not exactly, however their total weight together must be between 20 and 70 pounds and the maximum per monitor weight will be 35 pounds. One monitor should not outwiegh the other by more than 5 pounds. Their total width (added together) must be less than 56.5 inches (actual width measurement/not diagonal measurement). If you require your monitors to angle inward about 10 degrees, allow a maximum total of width of about 55 inches. IMPORTANT NOTE: Different monitors will often not align vertically as one might hope or expect when placed side by side based on variable VESA hole pattern locations.
