Unico is aware that these monitors do not work with older arcade games and has promised an updated control board to fix the problem for over a year. Every time I ask about the status of the updated control board they say the boards are not ready yet. This has been going on since February 2024. These monitors also have issues with control of control of color/contrast/saturation, horizontal/vertical resize, which Unico is also aware of and has promised to fix with the new control boards, but I keep getting the run around. I recommend ghat you don’t buy the monitors until these issues are fixed.
