Based on your answer
that "Display Port and HDMI transfers digital audio signal as well" it means I must have a sound card in my cpu or just monitor built in speaker? And if just use the HDMI cable but my monitor does not has built in speaker, what will happen?
2) HDMI cable is more better to plug on tv? not on pc monitor?
3) Are you using DVI or HDMI or DP?
4) What happen if dell u2412m plug with all these cables, what will happen, had u try it?
Sorry for asking too many question, now only I learn can use DVI replacing VGA

after long time using VGA only

1. nope, most motherboards/GPU have built in sound card and should be more than sufficient for casual usage. as for if monitor dont have built in speaker, then nothing will happen regardless if you pick DVI or HDMI
2. HDMI is the standard for TV. youll be hard pressed to find a DVI port for most Full HD TV nowadays
3. im using DVI, my monitor came one free
4. nothing happen, youll just pick whichever signal you desire. eg, i have VGA, DVI and DP connected to my U2313HM, all i need to do i open the mini menu of the monitor and select which input source to be used (can be done via Control Panel Screen Resolution as well)

at this part when he explain "normally i will suggest Display Port over the rest, cause its a non-patented cable (which means cheaper cable, dont need to pay royalty to use the branding like HDMI, which is why HDMI are rather expensive) supports up to 4K reso unlike DVI and HDMI"
Why he suggest to use DVI rather than DP?
many apologies for confusing you
what i meant was i would normally recommend using DP connector instead of the others. however given that you GPU only supports DVI, VGA and HDMI, i suggested DVI instead
