Hi there !
I bought the HP ZR24w ~3 weeks ago and was really happy with it - it's a great screen - until now. I'm using the DVI-connector with a 8800GTX. I've been away from the PC for around 2 hours and left the screen & PC turned on. When I came back, there was a black screen, the backlight was there and the tiny power LED in the bottom right corner was blue. The PC obviously worked, sound was there, I could use mouse, keyboard etc..
Interesting thing was that every time the screen should react, it showed the blue LED and the backlight: I connected a 19" screen to my PC for troubleshooting purposes. As I selected the 19" as primary device, the ZR24w was in Standby (or similar) with the orange LED. As soon as I selected it as a secondary or even primary device, the LED turned blue and the backlight turned on and stayed on.
So... What is it?
I already tried a few things (any devices disconnected from the computer, just mouse & keyboard, power supply and DVI-connector):
1. Turned Monitor & PC off & on again. Result: Exactly the same behaviour.
2. Tried to connect the ZR24w to my Laptop with VGA cable. Result: Exactly the same behaviour.
3. Connected my PC with "old" 19" screen. Result: Works perfectly, everything is displayed.
4. Reinstalled/Updated graphics driver (Uninstall - Restart PC - Install new driver - Restart) and installed HP monitor driver. Result: No change, ZR24w still causes trouble.
Any ideas or should I send it straight to HP support ?
(Hope my english is okay.)

I am having nearly exactly the same problem. If I power on/off the monitor I will see the desktop for a split second and then the screen goes black. This happens on both a Window 7 desktop and a MacBook Pro laptop. It's like it's getting the signal but not displaying it. The laptop thinks the monitor is working fine (it reacts different if you unplug the cable).

I have the same problem. New out of the box monitor goes blank after <1 second. The power light stays blue implying that the monitor is getting signal.
Tried connecting to two different computers with VGA or Display Port. Same Problem.
Product shipped 12/20/2011.
Waiting on HP Personnel to respond.
