2 Dell 2405FPWs; different firmware?

Hi all,

I just got my second Dell 2405FPW 24" monitor. I bougt my first one 3 months ago. I noticed the color looks different. And yes, the color submenu of the display controls is different:

Older one:

Normal Preset (sRGB)
Blue Preset
Red Preset
User Preset

New one:

PC Standard Preset (sRGB)
Mac Standard Preset (sRGB)
Blue Preset
Red Preset
User Preset

Rhere are the RGB presets:

Normal Preset: R 31, G 44, B 34

PC Standard Preset: R 32, G 38, B 29
Mac Standard Preset: R 31, G 34, B 25

I've see the User Preset of the newer monitor to match the Normal Preset of the older one. The color of the monitors are now very close.

Is there a way to update the firmware in my older monitor? Would I want to do that if it was possible?

Thanks,
Steven
