Frequently asked questions
What is the difference with the 9000 series?
The Alpha 4120 RGB shows 1 or 2 lines on a 7,62 mm pitch at 1300 nits. The 9000 series (such as the Alpha 9630i) has a finer pitch (6,25 mm), more pixel rows and up to 5 lines, and is brighter (1800 nits) — suitable when you want to show more information or finer graphics on the same surface.
Can I connect the Alpha 4120 RGB to my existing system?
Yes. The recommended connection is Ethernet: this links the display through the Alpha protocol to your network and applications, or you manage it with the Ooh!Media software (incl. USB upload). RS-232 and RS-485 remain available for backwards compatibility with legacy systems through AlphaNet.
How much text and which colours can it show?
4096 colours with text, photos and animations (RGB graphics). Per screen 1 line (15 characters, 114 mm high) or 2 lines (20 characters, 53 mm).
Is the Alpha 4120 RGB suitable for outdoor use?
No, this is an indoor display (1300 nits, indoor enclosure). For outdoor applications we recommend a display with higher brightness and an outdoor enclosure — feel free to contact us.
