A:Answer Alyoria,
Thank you for the question! With the length of this desk at 42 inches, let's assume these screens are 23" monitors, and then at a length of about 20" end to end, you could possibly fit two side by side on this desk. However, this still may be a little snug. I do not believe you'll be able to fit 3 on this desk.
If you're looking for a desk that has more surface area to fit 3 screens, I recommend the following:
