Question about VGA

[Frost3]

Hello, I was looking at getting a monitor and I was considering getting an Ativa AT220H 22" LCD Monitor from a friend. So, I have been doing some research and according to office depot the max resolution of the monitor is 1920x1080 (1080p) and it only has a VGA port. According to pcmag.com encyclopedia VGA cables only support up to 640x480 which isn't even close to HD. So, if I got a VGA to DVI adapter (not sure where to get one if they even exist) and used a DVI cable would that be a better option? Or does VGA work well with 1920x1080? I am not exactly completely familiar with cable lingo and stuff. What I do know is, is that DVI is better than VGA. I will be using the monitor for gaming and other everyday computer stuff. If any of you guys have any information on the topic to help me it would be much appreciated. I am just confused on how you can have a monitor that is HD but, only uses a non-HD VGA cable.

VGA can do 1080p perfectly fine...

 

 

The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640×350px @70 Hz (24 MHz of signal bandwidth) to 1280×1024px (SXGA) @85 Hz (160 MHz) and up to 2048×1536px (QXGA) @85 Hz (388 MHz).

As I said I don't know much about cables. Thanks. I have been looking around and it doesn't look like a VGA male to DVI female adapter exists either way, not sure if it would make much of a difference anyway. So, it can handle the 5ms response time too? From what I heard VGA cables were junk. Guess they weren't as bad as I thought.

I do what I want.

I had my 1080p monitor using VGA and it was fine.

VGA can do 1080p just fine, there's a chance that you will need to do some clock and phase adjustments for it to be perfect though.

I am not talking about VGA ports anymore I am just talking about the cables. Enderman talked about SXGA and QXGA. I am confused about those terms. Are all VGA cables QXGA? I was on one website that was selling QXGA VGA cables and UXGA VGA cables. Does anyone really know about VGA? I am looking at this wiki site https://en.wikipedia.org/wiki/Super_video_graphics_array#/media/File:Vector_Video_Standards2.svg and I just don't understand are those all display standards like supported by one VGA cable? I think that all of those are different cables on the chart but, I am not quite sure. What is standard jacket and plenum-rated? What is the difference between a normal QXGA VGA cable and a Flexima QXGA VGA cable? Is that something special that helps you get better quality or is it just slimmer?  :huh:

I found out that CMP rated and FT6 rated were fire code requirements and that Plenum meant that the cable is made to go through walls and ceilings… still need help with the other stuff. It looks like now on the market they sell 3 types of VGA cables SVGA (800 x 600 pixels), UXGA (1600 x 1200), QXGA (2048 x 1536 pixels). Where is a smarticle when you need one?

Well, I was hoping someone intelligent would read that and help me out but, I was able to do my own research on VGA cables and after many minutes I was able to find all the answers to all of my questions on my own. For others who don't know here is some information I have learned (it's from the internet and sometimes there is incorrect information depending on where you get it so my information may not all be fact). The VGA connector was developed by IBM in 1987 and it is a 3 row 15 pin connector. You can have many many different cables that use the connector. The cables being used have evolved a lot since the connector first came out. The VGA cable only had 640 x 480 pixels. The QXGA cable uses the VGA connector and is used super commonly today. The UXGA cables are still used with some setups because with QXGA you can get to EMI and RFI interference that can affect picture quality, but with UXGA cables you get superior protection against EMI and RFI. That's the answers to about all of my questions there. So, now I feel pretty educated on VGA cables. I wish someone could have told me so that I didn't have to do work. But, iz cool.  B)
