Question for Dan re: Nanoflash and Dreamcolor

Dan, I'm using the HP Dreamcolor monitor which, if fed the right kind of signal, has a very robust processor for accurate color. I've been pairing it with the Decimator MD-QUAD which, other provide the necessary HD-SDI to HDMI conversion to input to the monitor, lets me switch between multiple cameras as well as create a quad split, very helpful for a multi-camera shoot. However I've recently become aware that the output signal of the Decimator is not of the right type to trigger the Dreamcolor engine, so I am viewing an 8 bit instead of 10 bit signal.

HP has a white paper on the requirements for the SDI to HDMI convertor here:

http://h20202.www2.hp.com/hpsub/down...plications.pdf

I'm wondering if the output of the Nanoflash will satisfy these needs and provide the signal that the Dreamcolor is looking for. If you could peruse that white paper and let me know, I'd be very grateful. Thanks!

Dear Charles,

Short Answer: No.

Long Answer: Almost all HDMI outputs, from any device, are 8-Bit.

The reason for this is fairly simple. Most all electronic devices use commercially available HDMI transmitters. Almost all of the available HDMI transmitters have been 8-bit devices.

For example, as far as I know, all current camera's HDMI outputs (at this time) are 8-Bit devices.

In reading the spec's for the Decimator MD-Quad, they specify that the HD-SDI output is 10-bit, but do not specify 10-bit for the HDMI output.

While the nanoFlash can be used with the Dreamcolor, our HDMI output will be 8-Bit.

Your Dreamcolor monitor is an ultra-premium monitor and provides 10-Bit HDMI processing.

I hope this helps.
