ZR30W blinks!

A quick survey among users at our company using these monitor model shows, that 12 out of 26 devices are affected by the described phenomenon. As a commercial user we are thinking about looking for alternative solutions. First step is to contact our sales representative. My boss uses a ZR24w, but not much CAD-application. He could observe the same problem with his monitor. I have a three year old Samsung SyncMaster 245B and never had any problems although I use the same S20 hardware with same graphics adaptor like all other users connected to a ZR30w. The question is: what is different in the design of HP monitors compared to others, that leads to such annoying failures?

I've tried them at lower resolutions, different machines, different OS (XP & &) etc.  Nothing changes the way a particular sample works (or fails to work).  What makes me think this is a sample-specific defect is how much my three samples have differed.  One was bad, the second was literally unusable, the current one blinks just often enough to be frustrating but not outright maddening.  Stippi's post here about 12 out of 26 or so seems to confirm this.

I guess this means I'll call HP again and get them to send me yet another one.  Maybe I'll try to get them to send a new unit this time, instead of refurbs like the last two.

I can confirm the information about different hardware and OS (Win XP)! We also have been testing the ZR30w with different hardware here and have the same blinking-problem as with all other devices. Thinking about getting a monitor from another vendor as it seems to be a HP specific problem. Too bad, that we cannot recommend monitors by HP.

After many attempts solving this problem I found another track here  at HP's webste:

This may be a way to be gone: I updated all the video-card drivers regularly and one by one the blinking decreases. It looks like that new drivers for our video-cards reduce the amount of blinking and in many cases it dissapeared completely.

Sorry HP for suspecting you to be unable to fix problems which might never been your fault. Maybe video-card manufacturers didn't had the right specs to adress your monitors when the product has been new to the market, but meanwhile up-to-date video-cards with at least the latest drivers should deal with this.

I've been having the same problems for 6 months and hp can't figure out how to fix it so far. My theory is that since it sometimes takes up to 4 or 5 hours to see the first blink, all the blinking monitors are sent back to hp and the tech puts them on the test bench for 30 minutes, sees nothing wrong and sends it out as a working refurb.

So, you and me, the customer gets a replacement, which is a blinking refurb, and the circle continues.

I have 3 replacement monitors and they still blink and sometimes wake up with vertical stripes. The stripes can be removed by unplugging the dp cable and plugging it back in.

How do you tell if you got a new or refurb as a replacement?
