Old CRT Monitor for CNC Machines

LCD Benefits at a Glance

Don't let your outdated, defective and costly CRT monitor stick around any longer. Make the upgrade to an LCD monitor to take advantage of the many benefits they offer. We've outlined some big reasons to make the change, which will actually keep your machine running smoother for longer, cutting down on overall operating costs.

CRT Disadvantages:
-Extremely heavy and awkward to place
-Consume large volumes of electricity
-Image quality and color gradually degrade
-Extremely expensive to replace
LCD Advantages:
-Much lighter with flexible placement options
-Much lower use of electricity
-Clear and vibrant picture quality
-Longer lasting and cheaper to replace


Common CRT Monitor Defects:

The defects CRT monitors experience overtime can seriously hinder the operator’s ability to read the screen. When correctly identifying patterns or writing on the CRT screen plays a large role in the operation of your CNC machine and business, this can cause large amounts of downtime. Not only do these defects affect the operation of your CNC machine, but they also cause your CNC machine users to strain their eyes in an attempt to read what the monitor is displaying. This makes your workers and in turn your CNC machine less efficient.

CRT Monitor Replacement Makes Your CNC Machine More Efficient

Tri Star’s highly skilled CNC machine repair technicians now provide LCD upgrade services for your old CRT Monitors. This not only saves you large sums of money but also gives you a more reliable screen with unbelievably clear visibility. Our new LCD retrofits will be placed into the same frame as your outdated CRT monitor, providing a new monitor that works the same, and in many cases, better than the old CRT monitors both electronically and physically.

The new LCD retrofit is more energy efficient, has high contrast for an exceptionally clear picture and requires no new signal adapters of any sort, allowing your CNC machine to go back to work quickly and with higher efficiency.
