The 24” Acer monitor just fit. It’s a zero frame so the bezel is almost non existent. The only issue was that the controls were on the base of the monitor. So I had to relocate them. Simply remove the back cover and free the controls from the base. Carefully reroute the ribbon cable then stick the controls on the back. Also took the opportunity to remove the clear led piece (power led) so it doesn’t illuminate any longer. I just glued some mdf to the back box in order to the support the top and sides. Then used double sided tape to adhere the monitor to the those supports.
