3. INTRODUCTION: C708 is a 17" multisync color monitor. The horizontal frequency range is from 30khz to 70khz, and the refresh rate is from and PROGRAM, the micro-processor (u-P) control all the picture performance. From the key control, the user can change the H-size, V-size, V-center, H-phase. 9 - Acer AC701 | AC701 Monitor Service Guide - Page 10
