A year or so ago I picked up a refurbished HP w2408h monitor that’s been entirely satisfactory, although the backlight now seems to flicker occasionally. In the course of enabling the backlight sensor to see if that changes anything, I came across this useful bit of information about enabling the Factory Mode menu (lightly edited for clarity):
- Make sure you have video on your current input.
- Then turn off monitor.
- Hold down the “Menu” and ” +” keys while turning OFF/ON REAR Power switch. If monitor does not have rear power switch (ex. w2408) then just do with front power switch.
- Bring up OSD and scroll up/down to “F” letter at one corner of the OSD window.
- Press Menu/select button to enter Factory menu.
- Scroll down and turn off BurnIn.
- Scroll back up to “Exit” menu.
- Cycle power with front power button.
The menu isn’t particularly useful to mere mortals, although it does show total power-on hours (3700, IIRC) and some other settings. It seems the refurb shop shipped some of the monitors with Burn-In mode enabled, much to the confusion of purchasers.
Makes you wonder what other Easter Eggs lie in wait, doesn’t it?
