in terms of quality, Display Port, HDMI and DVI are the same. all three transfer digital signal to be output on monitor. only diff is Display Port and HDMI transfers digital audio signal as well. DVI only limited to video

VGA is analog signal, which means the video quality is adversely affected by length of cable. the longer the lousier unless you have signal repeater. digital cables suffer no such effects

based on the specifications of GT 240, they only have DVI and HDMI (ignore VGA, they should be obsolete by now). i would suggest going DVI unless you have built in speaker for your monitor which then you can utilise HDMI more

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

DVI max reso - 2560x1600 for dual link, single link max 1920x1200
HDMI - 1920x1080, unless HDMI 1.4 which supports 4K but at 30Hz

in terms of pricing, most HDMI 1.2 ive seen cost around RM40-75 depending on location

as for Display Port, its like you say, extremely rare but costs around RM50+

for that price, ill definitely take DP as it supports higher resolution at 60Hz

however, thats only for PC monitors. if youre looking to plug into TV, your best bet is HDMI only as most TVs uses that

VGA is still being used for projectors and certain monitors cause manufacturers doesnt want to increase cost and certain people who doesnt want to change connector port

that i really dunno the quality

those RM40 and above ones ive seen are those that are 100% reliable

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)

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

most Nvidia latest gen cards are already including DP ports on them

except the lower ends like GTX650 and below (GT610, 620, 630, 640)

already obsolete btw, first introduced in 2010. that should give you an idea how old is it

Nvidia card lineups are denoted in their middle numbering, which increases as close to the card's generation

for example GTX600 series
690>680>670>660Ti>660>650Ti>650>640>630>620>610

nah as long priced decently unlike those OP Monster cables
