E207WFP - Screen turns off and on

Video card or monitor. Can you try another monitor and see if it does it?

i have the same problem with the e228wfp model and an ati9000 pro . i think it is hdcp related problem . plz check your videocard and i think sapphire is doing correct videocards of x1300 ati. which i have not tested is if my diagnostic is correct yet. ill send all info i can gather. kindly, shocked.

mmm. i had a replacement (same model) monitor too. the failure continues. you can think that i have a defective ati radeon card. but it is not true, it worked fine with two crt monitors, even it was used with a flat panel phillips monitor 15" without any problem. So it has to be a compatibility problem. You can recognize easily that being the ati card older, and in good working state, it is the monitor or the interface, where to search. the only thing i found possibly troublesome in the specification was the hdcp ready dvi interface, well, the monitor has another not to forget problem. automatically adjusted as it is using the old vga interface it shows moire. for me this monitor is not a good choice because of the combination of problems , not allowing me a way to use it at full potential. i was expecting some kind of meaningful answer in support ppl, i mean with content referred to the problem, not a crude replacement or "your card is defective" against the fact that it works fine. And no more explanations, so i decided to search info here in the forum as a last resource. kindly, shocked17

congratulations. the new monitor did not worked for me. i had to flash the videocard bios, why the previous bios did'nt work fine could be an hdcp mistery, say mistery because nobody in dell was able to tell me what was the problem, no diagnostic program proposed etc... now i can see my boot screens again using dvi, but, im in the process of reinstalling drivers and directx because dxdiags shows i cannot do 3d testing. And i get flashing monitor when using the monitor like now, writing this message using firefox. i doubt that it will work after i reinstall drivers and directx but it is to clear things before i return the monitor and receive my money back, which i already asked to the customer care ppl, to find that they are not willing to after two e-mails. hope they recover ...common sense?. kindly, shocked

I had the option of using the VGA cable instead of the DVI, and it works fine, although I'd much prefer the sharpness that you get with the DVI. This is annoying.

I also have the same problem. I haven't contacted tech support yet, and it doesn't sound like they're going to be able to help me by looking at what's been said here. I have a Powerbook G4, and I'm using the E207WFP as an external monitor, simulataneously with my built-in LCD. I've checked the specs of my Mac, and it claims that it can support dual displays of much higher resolutions than the E207WFP can provide. When I am doing something, the screen goes off, and then on again. It doesn't happen while nothing is going on. It also happens when I'm playing a movie. I guess it happens when the video card is working away. I can't diagnose the problem further than that.

I also had a replacement monitor. It came very quickly, which i am pleased about (good job, Dell). However, I still have the same problem with the DVI setting. I think I may give up and settle for VGA. Perhaps it's my video card, but since it's built in to my laptop, I don't think I can solve the issue.

Just as a follow up on what I did following to solve the issue. I returned the E207WFP, and instead got the next model up, which cost more than £100 extra, the E2007WFP. It works like magic now with and without the DVI cable - no flickering on and off. So I guess my video card (ATI Radeon 9700) is fine; it just doesn't seem to like the E207WFP. It's a shame that I had to fork out an extra hundred pounds, but I do happen to use the computer for graphics quite a lot, so it's probably worth it in the end. If anyone else with a Powerbook G4 is having these problems, you may just have to pay the extra money for a E2007WFP!

Hi,

I just got a E207WFP and I'm having exactly the same problems connecting it to my 17" PowerBook G4 as you- the display switches on and off whenever there's any movement on screen.

Interestingly, if I open up display settings and choose a lower resolution for the monitor (1280*960 say) it's fine. Some of the other lower resolutions (e.g. 1344*1008) exhibit the same problems though, and using a lower resolution is hardly a satisfacory solution...

I initially thought the monitor must be broken, but after reading this thread I suspect it's a compatability issue with my Mac's Mobility Radeon 9700 graphics card.

Shame, since it's excellent value otherwise...
