Review: Viltrox DC-70EX 7″ HD-SDI Monitor

The other day on Facebook several people were asking about the Viltrox DC-70EX HD-SDI monitor, also known as the cheapest HD-SDI screen on the Amazon market. So here is a video review of the screen.

Here are some closeup pics of a video signal from a ARRI-Alexa Mini on the screen. You can see that it does do an odd thing when next to a solid color block. You’ll see this on the green screen. This is a deal breaker for the camera department folks who read this, but that’s no a real issue for us in the sound department.

It also looks like the video signal is maybe 8-bit because it has severe banding in the shadows. Again, dealer breaker for all the DPs and DITs… perfectly fine for a sound mixer or director. It honestly is sharp enough to pull focus off of if your a 1st AC.

And even though it’s not listed in the manuel it does seem to work just fine with 23.976 signals. To test the monitor I fed it a feed from a Teradek 600 that was connected to an ARRI Alexa Mini and the Viltrox.

In the end this is a really great HD-SDI for any sound mixer who wants a reference screen, check TC, and enjoy the camera return feature that this monitor can offer. Now here are just some photos you won’t get from the Amazon listing.
