I just recieved my nView Spectra in the mail. It seems to be in excellent condition, and has all the necessarry cables with it. However, I am having a problem with it. When plugged into a VGA source, the image flickers and scrolls up very rapidly. I think it might be a resolution problem, a driver problem, a problem with the VGA cable, or a loose wire. If anyone has any info regarding this problem it would be very helpful if you could tell me. Thanks in advance.
Aw yes! The old nview flicker! Take a look at your power supply and tell me what the voltage/amps are. I once had an nview panel that did this only when I activated the vGA input. The splash screen seemed to work fine. The power supply that came with it was far too weak to power the panel (was a replacment). Once I changed it to a more beafy power supply, the flickering stoped all togather and the image looked great! With nview, you can go anywhere from 12 volts 1.5 amps, all the way to 12 volts 2.9 amps (nview z series). I have a 10 volt 3 amp thinkpad power supply i use for testing all of my nview panels, and that works just fine. I have an nview spectra C [original] power supply right here on my desk so i just scanned a picture of it for you (shows the correct voltge/amps). Also, the center pin on the barral jack is the postive voltage 🙂. A new power supply with those voltages should be a since to find at radio shack/electronics stores if not on the web.
Hope this solves your problem

Thanks for the info. It came with that exact same adapter. Maybe I should try something even more powerful?
I think I'll look for one with a higher amperage. So, any other ideas on what could be the problem?
hi there,
@verbose:
since I am running the panels in Germany I have to use an adapter to get the needed 110-120V...
do you know if I need one which supports only 40W since the nView adapter needs it? I have an adapter for electronics from the U.S. which supports up to (if I understand that correctly) 200W but perhaps I need one that just can do 40W?
David, I found a power suplly for the sharp qa-75 at work and it produces 12V and 2.0A... this could be a chance also!

I think I found the solution!
The adapter that let me use U.S. electronics doesn't change the Hz value.
That means that the panels only get 50Hz instead of the 60Hz they need to run correctly... The flicker with the horizontal lines shows that it is too "slow".
I need to get one that changes the Hz value from 50 to 60Hz!
David, we'll see
The 50 or 60 Hz are at the input side of the supply (AC). The panel takes the 12V from the output which is DC. So i don't think that this could be your solution.
Try to set your resolution of the pc to 640x480 and then restart your panel. I had a similar problem with my Ovation 822. Worked only if the pc came with 640x480.

I see. So it has to be the VGA-cable...

It tried it with two PCs and my linedoubler all set to 640x480@60Hz and it is always flickering!
