Hello Merdincz, thanks for joining the Intel Community.
Please the following thread 3-Display Issues with HD Graphics 4000 Laptop (HDMI & VGA Config) Post #12
Can you change the Display mode to “Clone Display” instead of “Extended Desktop” under the Intel Graphics Control Panel? Let me know the results.
sylvia_intel i've just checked link which you shared and my laptop doesn't have any display port on outside so this mean i can only use Active desktop 3 section isn't it ?
Also i've checked your suggestion. I tried to change display mode from extended desktop to clone display but seems show only 1 of my monitors.
By the way my built in display seems connected from LVDS. is this mean my built in screen connected from display port inside of my notebook?
