HP 2475w Monitor - Blank color display - pixel test?

[OldKit]

Hi, I have this old WUXGA monitor, that I bought new in ... 2009 I think. Still works fine. However, it has an annoying habit which is now more annoying, perhaps someone can help me round it.

When the input is removed by the PC sleeping or powering down (or any other way AFAIK), instead of going blank, the monitor goes into an endless cycle: All red pixels on, then all green pixels on, then all blue, then all, then...etc, etc. It looks like a dead pixel test (I've not noticed any). But it uses the backlight lifetime and presumably several watts. I could understand if it just went through the cycle once, but it does it all day & all night if given the chance.

It happens irrespective of whether it's set to scan its inputs or default to a fixed one. GIG072 Firmware, it says, which from seeing one or two older queries, is not an early potentially buggy one.

I would prefer it just to go black like any normal monitor.

I don't want to give it a factory reset as it was calibrated by a third party.

Any ideas?

 Dont have that monitor but it seems to have been a good one. 

Manual can be found here 

The litesaver software supposedly can control the sleep behavior.

Good Luck!

Hi, thanks, I'll look into that - I probably have the original CD somewhere, not that new PC has a CD drive. Will take me some time, as nothing's going on new PC (no, not HP) until it works properly itself.
