I am using an Acer Aspire E15 with a damaged LCD display. I have a 4K Vizio E-series monitor as my main display.
I can get the video to display on both monitors or can blank out LCD by using fn keys or closing the lid.
Internal LCD is lower resolution than the Vizio.
The Vizio has to be tricked to display full screen by closing the lid on the laptop and adjusting the res to 720p.
Then using the web Chorus2 send a reboot (since the screen blanks when changing the output to HDMI1).
After reboot, the Vizio displays full screen.
If I set the display to 1080p it works.
Openning the laptop lid so the LCD is on, I have to start all over again.
Is it possible to force output to HDMI1 with a specific resolution that is different from eDP1 (the LCD)?
Additionally playing EMU's only displayed on LCD... How to force to HDMI1 Vizio?
