Since many of you guys are asking how to fix this i think i should make a post on how you can fix this with grub2win & some extra grub codes.

[Custom Grub Codes for External Monitor]

#1 vga=788 video=LVDS-1:d video=1920x1080

#2 vga=788 video=eDP-1:d video=1920x1080

[ Info ]

Try both of the above codes one by one & see which one works for you.

you can replace video=1920x1080 with your monitor resolution like

"vga=788 video=eDP-1:d video=1440x900 "


[Some FAQ for noobs]

#1 Why my laptop goes black after this ?

because by using this grub code you are forcing kernel to use you external display.

#2 Can we use phoenix os as extended display ?

No you can't it's only supported by some monitors if by adding above grub codes gives you extended display then you are lucky.

#3 What is LVDS / eDP ?

It's your display connector type that's being used by grub.

#4 How to find my display connector type ?

Boot into any live linux usb like Ubuntu & type following command in terminal

" Xrandr --query"

see which one is connected to your external monitor then replace in above code like :-

"vga=788 video=HDMI-1:d video=1920x1080 "

if you are getting HDMI as connected display.

#5 How to change too small or too big letter issues in monitor ?

Download Easy DPI Changer app from playstore .

#6 how to change my display refresh rate I've a 144Hz Moniter (aka Rich bois) ?

Update you kernel to latest 4.19.92+ And this line at the end of you build.prop (#/system/build.prop)
"debug.drm.mode.force=1920x1080@144"

#7 How to fix many game resolution ?

> for pubg you can use gfx+ tool & change your gamehelper keymapping to 1080/2k resolution.
> for other games just customize controls make buttons smaller & adjust gamerhelper keymapps according to it.
> if you mess up your keymapping any time just press reset button to set it default.

Thank you for your answer.
But when I don't use video=LVDS:d, I can still boot.
yes if you use grub2win you can boot without these grub code but in some devices you need to force system to display using External Monitor port that's why we use this code.
i can boot with my monitor without using these too.

So, how to let the 5.x kernel boot through video=LVDS-1:d without freezing the external monitor?
