Adding a switchable aspect ratio modification to a ProVid CRT monitor for 16:9 display
20 years old. Gear and prices may have changed since.
What the thread found
- A variable potentiometer inside the ProVid monitor controls the aspect ratio setting
- Installing two variable potentiometers of matching resistance values and wiring them to a switch allows toggling between different aspect ratios without opening the monitor
- Each potentiometer must be individually calibrated to produce the desired aspect ratio when selected
Depends on
- This modification requires electronic knowledge and soldering skills
- No confirmation that anyone successfully completed this modification
- No specific guidance on which internal component controls aspect ratio or where to source compatible potentiometers
