The workaround is to stop buying this crap.

As a designer I’m always disapointed by the poor quality show on digital projectors. Not only are they washed-out but always have a blue or red cast

Any thoughts or guidance on this – plz let me know.

I’m forever having to apologize that the brand is not. for instance ‘that lemon yellow they see on the screen but a vibrant clean yellow”

Comment on Barco Encore Preset Manager by Steve Wylie

Hi Pat,

I’m not aware of any discussion threads/etc on this – but I have used Preset Manager with the SPII Controller and it works well. It’s also rather simple to set up.

It’s important to note that the software won’t control the SPII units directly – it does need an SP II or Encore controller in the system – and the Preset Manager software simply recalls presets that you’ve created with the controller.

You will need to run the software on a laptop that has an IP address in the same range as the controller and SPII equipment (but is a unique address in the range so it doesn’t conflict), plus you then need to specify the IP Address of the controller in the preferences box within the Preset Manager software.

Feel free to comment back here if you need any more information! It’s a great tool, and its a shame it’s not better publicised!

Cheers,
Steve

Need to find some basic instruction on using this program. I have heard a good deal about how great and simple it makes the Screen Pro multi-unit multi destination rack set-up ready for show but could not get it to work over ethernet and 10/100 switch. Barco officially does not support and I have found nothing on the net. Any helpful threads would be appreciated. Thanks

Thanks for the comment Nicolas!

I’ve also since had success using the DVI Detectives to circumvent this issue.

I had this issue with some DVI DA`s and Scalers. One trick that worked for me was to put a “Gefen DVI Detective” at the computer`s output. Of course It will work as long as the content you want to show is not protected…

Not only It will tricks the graphic card and the OS with the EDID of a monitor, it will disable the HDCP right at the source.

In some cases, I even use it to power long DVI fiber extensions as the MacBook Pro seems to have issues with some brand. It`s really a lifesaver, it certainly worth the 80USD.

Please note that the “DVI Detective Plus” won`t work because it has a “HDCP pass-through” feature.

Hi Tom,

Thanks for reading! Yes, your problem is most likely exactly the same as I describe – because HDCP searches the HDMI signal path for HDCP compatible devices, it will have noticed that either your projector or your receiver is HDCP compatible, but the other isn’t – so the MacBook (in order to comply with HDCP specification) disables/blanks the output.

We have had some success circumventing this problem in the professional AV environment by using a device call the DVI Detective from Gefen. You install this immediately after your MacBook Pro, and the MacBook Pro will no longer see the other devices in the signal path, so it will no longer blank the output when it sees that one device supports HDCP and another does not.

The only down side to using a DVI Detective is that the signal chain will NOT be HDCP compliant – which means that you will not be able to play Blu-ray discs, or any other content that relies on HDCP.

Found your comments on HDCP interesting. I am trying to solve an issue at work. Connecting a new Macbook Pro with a min-display to HDMI – it works great with a long line to a Panasonic AE4000U projector, going directly. But colours go weird when I connect hdmi via the Yamaha RXV465 amplifier/tuner. Haven’t solved the problem yet. Had wondered if HDCP was the issue, even though no copy-protected disc was involved. – tom moffatt, NB, Canada
