Reader Mike ordered a brand new Dell machine that got here with a 21.5 -inch LCD display. Even though the screen consists of VGA, DVI, and HDMI inputs, it blanketed only a VGA cable–even though the setup commands suggest a DVI or HDMI connection! Mike wants to recognize why, and whether he must trouble shopping for a distinct cable.
I am going to answer in reverse. First, i’d certainly suggest the usage of a exclusive cable to connect your reveal to your pc. But, there is no want to trouble with HDMI unless you are making plans to observe Blu-ray films (assuming your pc has both an HDMI video output and a Blu-ray power).
Even then, DVI additionally helps the HDCP protocol necessary to view that sort of protected video content material. HDMI is surely high-quality for connecting a pc to an HDTV.
Therefore, i’d go with a DVI cable. That’ll provide you with a pure virtual signal (VGA is analog) and a much sharper photo at better resolutions. Your Dell ST2210 has a local resolution of 1,920 x 1,080, which you could and must use.
Don’t worry, a DVI cable won’t price you a fortune. sites like Meritline and Monoprice promote them for around $five-10, relying on length. (A six-footer have to be adequate for most customers.)
So, why do maximum video display units come with best a VGA cable? in all likelihood because VGA continues to be the maximum common sort of video connector international, and, consequently, the heavily produced cables are reasonably-priced. vendors may want to deliver DVI cables as well, however then at the least one might be going to waste.
There you have it, Mike. Drop some extra greenbacks and deal with your high-falutin’ screen proper.
