USBG-SVGA-1 & USBG-SVGA2 are two of a million different product names. It's an odd design: there are several case colours available. Each colour has a different address range. The rule is, you can't have two of the same colour on one computer. I've used the -1 version, putting 3 or 4 screens on all the financial computers in an office. It worked as advertised, and the price was right (around $35 in quantity). I've not used the -2, which supports higher resolution.
Don't expect to stream video to these displays. But they seem to fit your needs.
-SVGA2 may be only one per computer, depending on how you squint at the specs.
