graphics card - Dual/Extended monitors with VGA + HDMI to DVI


I want to buy two monitors for using with my laptop (without using the laptop's screen)
My laptop has VGA and HDMI outputs.


1st scenario:


VGA output of laptop -> VGA input of monitor +


HDMI output of laptop -> HDMI input of another monitor.
I tested extending screens with this scenario and it worked perfectly.


2nd scenario:


VGA output of laptop -> VGA input of monitor +


HDMI output of laptop -> HDMI input of HDMI2DVI converter -> DVI output of HDMI2DVI converter -> DVI input of monitor.




For the 1st scenario, I have to buy 2 monitors which have HDMI input.


For the 2nd scenario, I can buy 2 monitors which haven't HDMI input (cheaper than 1st scenario, because this type of monitor is cheaper than HDMI monitors).




Does the second scenario work? (extended screens, not mirror/same screen)


Answer



It will not be a problem. HDMI and DVI use the same signal, being that HDMI carries sound and DVI doesn't.


You can confidently buy a DVI monitor.
