1080p 18mb video card vga/DVI question?

Question

i have a 128mb ideo card that outputs to a 108p screen and which wouldhave a better quality: dvi or vga?

Answer 1

either or, but if you can get a deal on a DVI cable than I would say a DVI cable because all good video cards will use this type of interface...this will enable you to save money in the long run...possibly when you get a better card...

Answer 2

-DEFINATELY- go DVI!

If your monitor/tv has a DVI or HDMI interface, you should use a DVI or HDMI cable to connect it to your computer. The reason is two fold:

1) If you use a VGA cable you are converting the digital image from the computer to analog, sending it to the monitor which then converts that analog signal back into a digital one to be displayed, which means you are doing two extra conversions that are unnecessary and can add artifacts and reduce image quality.

2) Digital signals greatly increase resistance to interference and noise, so if you've got a power cable or a speaker or something nearby you can get reduced image quality over VGA. Since DVI is digital its almost impossible to get any 'noise' or 'interference' problems, unless the cable is horribly frayed or bent badly.

I'd recomend checking out monoprice for cables, link below. Dont waste your money on an $80 DVI cable when you can get the same thing online for $8!

Oh, and if you have an HDMI connector on your tv you can use a DVI -> HDMI cable, since HDMI is basically the same DVI signal but has a different connector (HDMI also supports audio).

I found this on another forum...

DVI is better than VGA for TFTs because they are digital and VGA is analog. A TFT displayes its picture digitally, pixel per pixel. Via DVI the panel gets data for each pixel, so the picture generated in the graphics card will match exact with the pixels on the panel itself.

Not so with VGA. First, the picture is generated digitally in the graphics card. Then it's converted to analog. In the TFT they will be converted again to digital (=> senseless twice conversion => quality loss), using the phase and the clock, and it'll be calculated which pixel should display what color. As the phase and clock can't be adjusted so precisely that a pixel of a picture generated by the graphics card will be displayed by the appropriate pixel on the panel. Means that the picture will be interpolated a little bit, which again means quality loss.

The electron cannons of the CRT need analog signals, that's why VGA is the best for CRTs and DVI would make no sense here.
For TFTs, DVI is the best. I won't get a TFT with no DVI.

Answer 4

Digital Video Interface sends a pure digital signal to your monitor while the VGA connector compresses it to an analog signal which the monitor converts back to digital. Technically, the DVI connector is much better. If you're using a 'standard-size' monitor (15"-21"), it's unlikely that you'd notice any difference. With a larger monitor (such as a 42" flat-screen), definately go with the DVI.

Answer 5

When your computer sends the VGA signal, it must convert it to digital then back to analog in order to display it properly. With DVI, there is no conversion taking place. VGA accepts analog signals whereas DVI accepts purely digital.
Due to the conversion of signals and the pure form of the digital signal, the DVI quality will be better.

Answer 6

VGA cannot handle 1920x1080 resolution. It maxes out around 1600x1200.

A dual-link DVI will handle 1080p video. You would want this anyways because it is digital and less signal degradation. VGA is analog.

With only 128MB, you are not going to get very smooth video. It should be quite choppy at that high resolution.

Answer 7

ok.. in words of hardware you need to bypass right into a save and tell them what your funds is and tell them to get you the superb card for that cost. i imagine in case your operating Vista residing house correct fee you need to get yet another 2gb of RAM, processor seems ok. also, try a diverse software media participant. For the jiffy I used Vista, i stumbled on diverse gamers worked more beneficial than others. the superb one i stumbled on replaced into called VLC media participant, which seems to apply a lot less elements and be extremely a lot less jumpy than the mainstream ones.

I Think vga but im not shure
