I am not sure if this issue has been brought up, but I am having a problem with my 4100. The EFIS display is blank. All of my other controls, displays etc. work fine, but the EFIS. I fly under Win 10, FSX-SE. All my drivers are up-to-date, and my computer meets all requirements If anyone has a direction to send me or an answer, it would be greatly appreciated.

Most likely missing fonts, two common solutions:

• Reinstall ensuring the installer has admin privileges (run as administrator)
• Copy the font files from "...Microsoft Games\Microsoft Flight Simulator X\Fonts" to Fonts in the Control Panel

Or it could be you have the EFIS display brightness set too low

Thanks I'll give that a try.
