Perfect for your home studio
Jan ( 12.03.2021
After using the monitor for some weeks with my Blackmagic design ATEM mini Pro ISO I am super happy. The USB-C port can be used as webcam for my Microsoft Teams calls. Solving the problem for my ATEM mini Pro ISO where I need the USB-C for recording to SSD. The HDMI and SDI can be used at the same time, I can then send the "program" from the ATEM mini Pro ISO to my big monitor plus to a monitor next door over SDI. The SDI input is used to connect my UltraStudio Monitor 3G from my Mac mini M1. in this way, the Monitor can be used for several different purposes at the same time. The Monitor have a Fan but make almost no noise. I also have the 12G version of the Monitor and that make more Noise. If you don't need the 12G SDI (4K Support) I can only recommend the 3G and save some money... Note: I have only used the Monitor indoor so no comment to the brightness if you need to used it outdoor.

Gutes Gerät
Le Maze 03.11.2021
Blackmagic ist schon eine spitzen Firma! Aber: Ich kann leider keine 5 Punkte geben, da trotz aller qualitativ hochwertigen Verarbeitung, 1A-Menüführung und einem sehr eindrucksvollen Funktionsumfang, hat der Recorder ein Manko: die Farben werden nicht ganz korrekt dargestellt. Im Vergleich z.B. zum iMac Retina 4k Display hat der Blackmagic einen sehr deutlichen Grünstich. Wenn man aber diesen Nachteil kennt, ist es für meine Zwecke nicht weiter schlimm.
Also, alles in allem 4 Sterne.

gewohnte Qualität
Alain.k.w 10.06.2021
Bevor ich mir den Video Assist 7" 3G zugelegt habe besaß ich den Vorgänger. Damit habe ich die Präsentationen der Sprecher*innen auf Konferenzen aufgezeichnet. Das Gerät wird zwar ultra heiß aber die Qualität ist super. Jetzt bei Hybrid Veranstaltungen mit Anwesenheit vor Ort und Digital via Stream kann der Video Assist seit dem letzten Update als Videocam verwendet werden. Somit kann das Videosignal vom Sprecherrechner mit den Slides direkt in OBS zum streamen eingespeist werden und gleichzeitig wird das Signal durchgeschleift zum Beamer. Einfach großartig und das zu einem wesentlich günstigeren Preis als sein Vorgänger. Der vier Jahre problemlos durchgehalten und fast die Hälfte des Einkaufspreises wieder eingespielt hat.
