Kona, 1080psf23.98 and PVM-20L5/1 monitors
on Dec 29, 2010 at 9:02:32 pm

We are having an issue with a few of our online monitors as we make the transition to 1080psf23.98

We have four PVM-20L5/1 monitors yet only two of them correctly display a 1080psf23.98 signal when fed to it from our Kona 3 cards. The other two display an image that looks like this http://i.imgur.com/zoJTr.jpg

I can hook two of the monitors up to the same source (AJA Kona 3>Monitor by component) and have one display the signal correctly and one look wavy. Does anyone know why this might be? Is there a monitor setting that may be off?

Sorry if this isn't the right forum, but it seemed like the closest I could find. Thanks for any suggestions you may have.

Thanks for the response.

The sync to the bays is usually 29.97, however it can be changed to 23.98 and whatever it is set to is sent to all the bays.

The problem seems to follow the monitors. If there are two bays, one displaying 1080psf23.98 correctly and the other wavy and I swap the monitors the problem stays with the monitors rather than the bay.

We also had one of the bays that was displaying fine for the first few days of 1080psf23.98 then after a computer restart the picture went wavy.

Open the aja control panel and assure yourself that you are getting 23.98 trisync or set it to free run.

And if you set Sync to 23.98 and try again?

If that doesnt work, then perhaps they aren't /1

No luck with the 23.98 sync.

I called Sony and was able to confirm that they are all /1 based off the serial numbers. Unfortunately their full tech support service is closed for the holidays.

Thanks for all the suggestions.

Well, either they are mistaken or there's no joy in Mudville.

The 2 series will play 23.98Psf ie if your serial # starts with a 2 it will do 23.98 via component
same with the 14 L's

But you said that at one point a monitor was working and then a few days later it wasn't? I don't know, but i would suspect some sort of system setup/config to be the culprit.

Also, monitoring @ 29.97 on those monitors (24p with the Kona adding real time pulldown on playback) is much less headache inducing than watching 48i. But maybe thats just my opinion.

Please check to make sure that you are working in PsF and NOT P on those displays that you are having issues with. CRT displays cannot show a "P" signal any more than they can show 24.0 fps.
