Windows 10: Is it possible to modify a LCD screens default(no input screen color?)

this is a rather odd and petty mod id like to do, on a special screen i have on my case (a sonwblind s case) id like the no signal or default background to be white instead of black, reason is because this is a very special translucent that the color black displays as SOLID and cannot been seen through where the color white is completely translucent. so when i start my computer or the little hdmi dongle isnt plugged in i cant show off my cases internals through the glass panel until i fully log into a OS with a white background for that screen. im sure it can be done as i remember a old dell lcd i had would cycle through all the rgb colors when no display was found. perhaps a EDID modification can do this?

Is it possible to modify the default User Icon on the login screen?

This is not the Logged in User Icon, this is the Default user or "Other User" Screen



On Windows 7, this was modified with the AUTHUI.DLL. Doing the above steps of modifying the User-XXX.png files has no affect

 

Is it possible to modify the default User Icon on the login screen?

Here is a screenshot of my two user accounts showing two different icons. When I login to either account the icon shows on welcome, login. lock, switch user and any other screen where users appear. Dont know much about png etc so never touched those files. I have found many things changed in Win10 from Win7. All I can say is my user icons are the way I want them and I changed them using the method I suggested. Sorry I cant solve your problem but I'm sure someone on this site will eventually come up with a better answer than me. Regards .

 

Setting the default input method for the Windows 10 login screen

I had the same question but with French being the default on Windows 10 rather than the one I wanted so I ended up here.

HoD is very close. I was able to use his suggestion to find the solution for me. This solution uses your current display and input language to change the Welcome screen and possible for new user accounts if you want. So make sure you have the display and input settings while logged in that you want to apply to the login screen before doing the steps:

1. Click the language on the Taskbar.
   
2. Then click Language preferences.
   
3. At the bottom under "Related settings," click "additional date, time, & regional settings" which opens the control panel
   
4. Click the "Region" option
   
5. Then go to the far right tab "Administrative". (HoD's step 2)
   
6. In the "Welcome screen and new user accounts" click copy settings. (HoD's step 3)
   
7. Tick "Welcome screen and system accounts" (and "new user accounts" if you want it to be applied to those as well). (HoD's step 4)
   
8. Click Ok. (HoD's step 5)
   

I was able to use HoD's suggestion to find the solution here. It's for Windows 8.1, but works on 10 so far.

Hope it will help you, too!
