Dotronix has been selling and repairing CRT-based monitors and electronic display devices for over 40 years. Our products are used in a wide variety of applications including airports, medical device manufacturers, CNC/machine tool manufacturers, financial firms, trading floors, retail stores, and many others.

From broad product offerings to quality, service and support, no one gives you more than Dotronix. That’s why we sell more monitors than any other U.S. independent display-only manufacturer. And that’s why we will meet your needs better than anyone else.

Quality Products

By offering quality products, service and support we have quietly grown to be a significant independent display-only manufacturer. As a result of this growth we now feature one of the broadest product offerings in the industry...

No one offers as many options in display size and performance as Dotronix!

Dotronix designed and manufactured the popular BC-Series and CD-Series of monitors. We also own several monitors previously created by companies such as Ball and Audiotronics.

From high resolution, large screen monitors, Desktop Publishing, Computer Graphics, and Medical Imaging to banks of small monitors for financial institutions, security systems, transportation and many other applications.

Reliable Repair

We can replace or service nearly any CRT-based monitor. Check our List of Manufacturers to see if we can repair your broken CRT monitor.

The quickest way to get your Dotronix CRT, CNC, Ball, Audiotronics, or any other screen repaired is to first give us a call.

Dotronix warrants that for one (1) year from date of original purchase, it will, at its option, repair, replace or refund the purchase price of any product which it manufactured that proves defective in material or workmanship in normal use and service.
