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 ?

#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.

hi, after installing the os, the resolution always remains 800*600. i've tried to change it using the gearlock, but it isn't working..
normal Phoneix os was also showing this same problem in my laptop, that's why i had to switch over to prime os and it isn't giving any trouble related to resolution,
could you please help me to solve this issue of resolution problem in DarkMatter?
TIA

Nice Thank you! THIS FIXED MY ISSUE! Laptop screen is 1440p resolution and my external monitor was 1080p so im guessing the external display was cropped because it was showing in 1080p and not 1440p? With this code:
video=eDP-1:d video=1920x1080
it disabled my laptop screen and enabled the 1080p monitor to fit to that resolution. Awesome Thank you! Playing on a 14 inch 1440p display was excruciatingly painfull haha, everything was so small haha and the upscaling made it look bad, 27 inch 1080p is much better :D

See my highlighted line in the screenshot below. You have to add the code there after DarkMatter-Exo4.7 vga=788 video=eDP-1:d video=1366x768(Here I wrote 1366x768 because my tv resolution is 1366x768 and you should know your tv resolution and replace it there after "=". And one thing you have to add the code to all the lines below like I did in the screenshot.

what vga=788 does bro?
it forces kernel to run video on a specific resolution if auto detection of resolution by grub is not working and you get cropped resolution.
these are the vga=xxx parameters you can use with linux kernel

hey i am using kernel 5.4.140 found any solution for external display ?

Found any solution ? Please reply
read the post again from FAQ section and read it carefully it will answer all of your questions don't just jump on grub config & start testing the settings i 've given here.
you need to find your display / HDMI port name.
input that port name in grub
set the resolution of you monitor and save the grub file.
