Tech Tip

Don’t Blink

So, this week I needed to push out a tip that I stumbled upon today. Specifically this relates to the Panasonic AV-HS410.

In the past, I have had instances where a display device downstream of this switcher may start to blink. Items have varied from Christie projectors, downstage monitors via AJA converters or other displays with Monoprice converters. I was only ever able to narrow it down to certain slides from graphics machines (PC or Mac). I assumed color space in those slides was out of bounds, but assumed the converters or switcher would convert/limit it upon input.

Today, I think I have the solution. While setting up multiview from SDI5 to a Monoprice 1×4 DA to multiple MP SDI to HDMI converters, there was a whole lot of blinking going on. I reviewed the options for the SDI out menu and saw “SDI Limit”. It had been set to “Off”. Randomly, I tried “108” and everything settled down and worked perfectly. Now that I had a minute to look at the manual, I can suggest using “100” instead, but we are in show now.

Here’s the gist though. This setting applies to ALL SDI outputs no matter which one you apply the setting to in the menu. And the numbers refer to percentage of color space, limit to 100%, 104, 108 or off.

Here’s the screen cap from the manual:
