I knew how to do this once but now I forget. I have a LK202-24-USB-WB from an older MX (pre fan controllers..).
How do you change what is displayed when the system is booting? Is there a way to change it back to the default?
LK202 Splash/Boot Screen
You don't need a specific piece of software to change the startup screen however the best way to this is to send the unit 254 66 [40 characters] in decimal. You can do this easily in LCDC. When testing the display and in the text box you enter the following:
[##254][##64][Matrix Orbital]
[##254][##64][Matrix Orbital]

I was having the same difficulty but saw that in version 1.05.27 of LCDC there's a little green box/button on the bottom right hand corner when you're in screen builder mode. Highlight a screen and click on that button and that becomes your new startup screen.
Other than that I don't know what else to do

well this answered the question that i posted in another thread but my next question is how to import i guess a qraphic like the matrix splash screen? I just got this thing and have really no idea what i am doing but its moving along quickly:) is there an easy tutorial on how to make a custom splash screen with my own little graphic?
