Built in lcd display not reading properly?

[ExoMale]

So I have this generic cube case that has an lcd screen built in the front, my guessing is its for temperature reading, but because this case is old and cheap and was second hand it doesn't seem to be displaying correctly??

I have the molex plugged in, but I don't have a drive installed, so no windows if that's what I need for any related software, but this is the first time testing it and I dont know what to have expected really, it would be nice to get it working though.

Picture would likely be helpful, my old pc had a matrix orbital display in it and it basically needed drivers and a 'companion app' before it did anything. I'd assume it's the same situation here.
