We have a few of this in our arsenal. This version with SDI input is great as it allows for a complete full range of video sources from HD SDI, to HMDI, to composite. They are fairly rugged too and can take some mild wear and tear.

Not bad

It's not clear from the specs or the documentation, but in addition to its many other capabilities, this monitor does a wonderful job with the horizontal flip you need for use with a teleprompter. In my case, I'm using it with a small desktop teleprompter that typically uses an iPad to show a PC screen instead.

The A12 is a vastly better - finer and more capable - monitor than most monitors meant for teleprompter use displaying text. (They may have other advantages for text.) I'm showing various kinds of screens through it, not just scripts. You also need to turn off the underscan if the edges of the screen matter to your projects.

I'm writing this review using the A12 reflected through a teleprompter right now, and happy with the result.

I'll revisit this in a few months, after I've had time to see how it does over time and in multiple contexts, but the out-of-box experience, plus a few days, has been great.

This was my first purchase for a monitor for larger productions. I realized I didn't really need 4k as my Black Magic Ursa only outputs SDI to 1080 but still happy with it. Mount it on a tripod and away you go. I'd only advise to purchase a battery mount with it.

I love this monitor

If you are doing multi cam broadcast or complex routing this is a great device. I have it routed as the first stop for my inputs it displays the incoming and then reclocks the signal and loops it out to the switcher and I do the same with the outputs as well. The audio waveform display has saved me in troubleshooting many times.
This is a great product and functions perfectly.
The little screens don't look amazing color wise but thats not what they are for this is a confidence monitor / reclocker.

Works just fine with HDMI and tripod mount. A bit too big for handheld.. Additional bracket made to support weak ball mount So far,satisfied customer!

This monitor is great for indoor and outdoor use. It is very lightweight and thin. The histogram is a very helpful tool to have. Several input options.

I'm a DoP & DaVinci Resolve Colorist, I have been using this monitor
for the last 6 days and I'm impressed with the quality and
with the versatility that I have with this monitor. So far so good.

Cons: - Monitor's sun hood is one piece of plastic, looks & feels 
a little bit cheap and since is all one piece, the sun hood 
won't close like barn doors, so, removal (for transportation) 
could be a little bit annoying because of the 3 knobs that have
to be screwed and unscrewed every time. 
I wish the sun hood could be more like barn doors, 
easy open easy close. 
(minor thing in my opinion, Still great monitor)

Pros:
- Great to have as a client/field monitor on set
- Lightweight & sharp enough to use it with a wireless follow focus  
for the AC.
- The A12 is a Portable & NOT a bulky monitor.

This monitor on a Mini Table Top Tripod + MacBook Pro + Premiere or DaVinci Resolve/ etc. = Very Nice Mobile Post Production Set Up with an affordable & great monitor.
btw, I'm in a hotel lobby right now using this monitor, (on battery) my laptop with Resolve and I love it!

Nice Monitor, great selection of inputs
