Overclocking Tutorial

Diamondtron HSync & VSync Unlocking Tutorial (NOTE: Only works on 22" SB monitors):

  • Turn off the monitor.
  • Turn on the monitor while holding the EXIT button until you see a raster image then release and press EXIT again and you will see the FACT DATA menu.
  • Press the (-) button once to set the data value to 255 then press the (+) button to set the data value to 5 then press the SELECT button.
  • Navigate to the right in the OSD menu until you find the FACT DATA menu again.
  • Press the (+) button until the DATA value is set to 99 then press the SELECT button.
  • Press either the (◀) or (▶) buttons and you will be introduced to the FACT DATA-E2P menu.
  • Cycle through ADDR to change DATA values:
  • Change DATA Decimal in ADDR 004 to adjust the HSync Minimum +1 (31 is 30KHz)
  • Change DATA Decimal in ADDR 005 to adjust the HSync Maximum +1 (141 is 140KHz)
  • Change DATA Decimal in ADDR 006 to adjust the VSync Minimum +1 (49 is 48Hz)
  • Change DATA Decimal in ADDR 007 to adjust the VSync Maximum +1 (161 is 160Hz)
  • Press the EXIT button after each ADDR modification to save each address value then enter the FACT DATA-E2P menu again to change other ADDR values.
  • Exit the OSD.

Notes

  • This tutorial only applies for 22" Diamondtron SB monitors (and their rebadges) such as the 230SB and 2070SB.
  • The maximum known limit for the VSync and HSync are 254Hz and 152Khz respectively.
  • This tutorial does not need any additional equipment unlike Sony's WinDAS.
