Luke –
Just an initial note. The monitor correctly handles HD-SDI video/audio directly from a Varicam. No audio distortion.
ANSWERS TO YOUR TESTS:
1. The audio output from the RCA monitor jacks is fine all of the time. When outputting HD video, the HD-SDI audio is distorted, the RCA audio output is fine. Switching to SD-SDI, audio is fine on both the RCA and SDI.
2. From the desktop using Itunes as an audio source: The monitor would display all frame rates except for 2K settings. Up to this point, I had only tried outputting HD at 1280×720 (as I have 720P source footage). When I switched to any SD or 1080 output setting, the monitor would display correctly and the SDI audio was fine. The analog audio was fine at all frame rates and settings. Changing the display settings had no effect on the RCA outputs or the XLR outputs. So this appears to be an issue with just 720P HD over SDI. Again, I used this monitor with a Varicam at 720P and the audio was just fine. I don’t have another SDI monitoring device at the moment to perform additional tests, but it would appear that the issue is with the 1280×720 output settings.
Thoughts?
