Weelcome to the forum Thatmosis.
There is usually a LCD / screen item in the menu where you can choose for how long the screen is on ( with the video footage ) the speed you see, that is the screen saver, and you might have to turn that off as i think it would otherwise override the LCD / screen timer.
Mind you some systems you can not keep the LCD / screen on all the time. it might also be illegal in many places, it is here in Denmark, though you would probably have to really PO a cop for him to nail you on that.
the LCD screen off time are generally from like 10 seconds to a few minutes or 5 at the most, but some do have a OFF too, in which case the screen would be on all the time ( having the screen on all the time generate extra heat, i personally use this when i test cameras CUZ we Danes dont really get HEAT even in the best of summers )
'Also these days, not many systems have that option of displaying the speed as a screen saver, it was popular with some brands back in the day, but i would lie if i said it was ever a norm.
