Difference between VGA and DVI

[PlaneName]

I've been using VGA for years and never tried using DVI. Because I've hear allot that you will not notice a difference between the two but for gaming and movies you will see a difference. Now when sometimes playing games at 40FPS-50FPS I am realising that the performance went choppy (seem's like at 20-30FPS when you move passed the obstacles and environment on the game engine). To me VGA can't transfer quickly enough?

Another thing is when you are viewing long distance there is some lines and textures that doesn't look right. You can see lines around top of an building, trees, floor (from long distance) and such that looks choppy, I can't explain it but maybe some of you may know what I'm talking about (I know that anisotropic and antialiasing will fix it but I already set it all on high and on in Nvidia settings as well).

Is these the things that DVI will improve in game? and better image quality? is this the difference that they were talking about? I'm using an 1680X1650 monitor.

The main difference is that DVI is a digital connection... In the early days of LCD monitors, this made a big difference in image quality, but not so much anymore. By and large, the only thing you gain with DVI at the moment, for most people anyway, is that you don't have to do that auto-adjust thing with the monitor if it ends up the display is a little off-center. There is naturally some quality loss from the digital signal native to your video card, to the analog VGA, back to the digital for the LCD, but you have to really look hard to find it these days.

Going forward, DVI has more bandwidth, so can support higher resolutions, but until we start seeing 4K panels hitting the market, it's not really that big of an issue. Most 30"+ monitors do require dual-link DVI, but again not something most people will be particularly bothered by since they don't have 30"+ monitors.

I highly doubt you'd see any improvement in your issues with DVI. Given your current resolution, you might well be at the upper end of what VGA can handle, and be forced onto DVI at some point, but until you upgrade monitors, don't worry about it.

Thank you, yes it does seem that VGA is at the end of the road for me. DVI has more bandwith on higher resolution? That's nice maybe VGA can't support my GTX 560ti in 1680x1650 resolution that well, the monitor sometimes cause the WSOD and it always lost connection between the GPU and the monitor... which I have to force my PC to restart or I plug of the monitor power. (It's not overheat issues, it's when I switched the monitors with the higher resolution it started doing this (it rarely does it). That's when I started to do some more research and I realise that this monitor is cheap or VGA is up to it's limit's.

I will buy an DVI cable for the monitor which it can support it and hopefully I can see some difference between the two and see if I see any changes.

summed it for me. go dvi if u can.

Sometimes old school is better ... think of all those projectors you sometimes have to use...

Will these cables do? Thank's guys for the advices.

With a digital signal the brand is not very important. As long as it can carry the signal according to the specification it will look exactly the same. The only thing you want to ensure is that you buy a dual link cable. It's actually not even required at 1680 but you might want to use it for something else later and regret only having a single link.

Single link will do up to 1080p or a little higher. The only monitors that need dual-link (or display port) that I can think of are the 20" monsters with 2560x1600 resolution...would love one!

I should get this right?: (without the 4 pins next to the minus) these doesn't support analog which we don't need anymore...

I will not be getting an single link, which is this you guys talking about?

Yes that will be great monitor the 2560x1600 but my graphic card won't handle it. I wanted to change to DVI because I was having issues with the WSOD and when my GPU lost connection with the monitor (black screen), while I was playing an game, which I have to force my PC to restart. It started all this when I have the 1680x1650 monitor. It's not overheat issues, which I checked. GPU runs at 65-72C and CPU runs at 60-70 C (Yes it's hot but this is the Q6600 B3 version CPU which can take more heat than 80C). I was saying that my CPU runs like that all the time with the 1280-1024 monitor which I have no problem with the WSOD or the black screen.

So I did more research and the only thing I found that is the monitor is cheap which I have to lower the "Digital Vibrance" which I set it to 30% and lower the brightness. Which did less WSOD and the black screen but it's still occurring when I turned of the monitor for about 1-2minutes then turned it on the WSOD appears, which I have to plug of the power from the monitor then place it back which fixed it but sometimes not. I have to turn off the PC and plug of the monitor for about 1-2minutes. I did more research and realise that my monitor can't handle the GPU. I really don't know yet, until I get that cable and see if the problem is fixed by using an DVI cable. There is only a few forums about the WSOD (which they called it), and I wan't to know if it's the monitor or the VGA it's up to it's limit.

I also tried installed and uninstalled the drivers and nothing still fixed. I also tried getting an older version of drivers and still nothing.
