Please add a feature allowing display of a custom .bmp 24/7/365 with for example a company logo and contact number.
That feature is already available through branding packages.
But not to ordinary users, only to distributors.
Oh. Thanks for that. Testing.

Unfortunately there’s no screen=branding-logo or something. Please add?
Branding package is special additional package that you can make for you on the mikrotik website if you are registered distributor. Otherwise no chance, bad luck.
I’ve already done that. Everything works, but logo is displayed only during boot, instead of mikrotik’s logo and doesn’t appear later (or I don’t know how to make it happen)
Neither I. Maybe it works as intended by mikrotik. May happen your question is a feature request more than that.
No comment.
See? I told you…
But besides the fun. I am keeping the displays rather off because the pictures get easily burn into the display. They are of quite poor quality.
It’s better to put a sticker on the device and it is applicable also on the devices with no display.
We keep the displays off, centrally, on every device – because they’re useless. We also apply stickers. This way LCDs would become of any use for the first time ever. Also, we couldn’t care less about images burning in. 
So, any hope for this? Or are you gonna give a fart only about customers that buy your devices to setup a home router, instead of ISPs that buy your devices to do business, who put you on the map?
