Arcade Monitor Image Adjustment: Brightness, Contrast, Geometry & Screen Position Tuning

     Arcade monitor image adjustment keeps the game display stable and comfortable. Old LCD and CRT cabinets often suffer image shifting, distorted geometry or cut edges after transportation. Technicians can adjust image parameters from OSD menu or service potentiometers.

     Basic parameters: brightness and contrast. Brightness controls screen luminance; contrast defines difference between dark and bright areas. Too high brightness accelerates screen aging. Set brightness so all game UI text is readable without eye strain.

     Geometry adjustment includes horizontal size, vertical size, horizontal shift and vertical shift. Adjust H-shift and V-shift to center the game picture. Adjust H-size and V-size to fit the game frame within the screen bezel, no cropped UI.

     Check flicker and color temperature. If image rolls vertically, check V-hold setting. Save OSD settings after all tuning and mark the values for future maintenance.

 FAQ

Q: Screen geometry drifts after moving the arcade cabinet?

A: Vibration during transport changes monitor settings. Re-run geometry adjustment after relocation.

Q: LCD or CRT monitor has different adjustment menus?

A: Yes. CRT has more analog potentiometer adjustments; LCD uses digital OSD menu.
