Autocad performace - VGA vs DVI

[mrkmpn]

This may be a stupid question, but can anyone tell me if there is a noticeable performance difference in autocad between these two?

 

I was having issues with autocad crashing, at least once a day, but on one occasion 3 times in one day. I hadn't experienced this until I started drawing tank battery layouts in 3D, and it only happened with realistic view turned on, which I find to be "easier on the eyes" than conceptual.

 

I upgraded to an autodesk certified video card (firepro 4900) and doubled my system RAM to 8GB. I also recently acquired a larger monitor to get a little more screen real estate (switched with another employee that didn't need a monitor that big.)

 

One thing I didn't think about was the fact that this larger monitor only has a vga port. Since my upgrades autocad is running way more smoothly. The 1st thing I noticed is that I no longer have to wait a second or two after hitting shift + mouse wheel to 3D rotate. I'm just wondering how much it difference it makes with VGA vs DVI.

 

Eventually I plan on talking the boss into letting me order another monitor this size (23") so I can do the dual monitor setup and will make sure it comes with DVI port, but I'm going to wait a bit since I just bought the other upgrades. It seems like they start getting suspicious that I'm just buying "goodies" when it comes to things like dual monitors. Non technical people just seem to think there's no reason anyone could need two monitors.

They both transmit video from your computer to your monitor. The difference between the two is in the way the signal travels. For VGA it is analog while for DVI it can be either analog or digital. DVI will give you a better, sharper display as compared to VGA. I don't know if you can qualify it as strictly a performance gain but certainly your eyes will appreciate the difference after you have been sitting in front of your monitor for eight hours.

 

I still make do with a single 24" monitor but there are CAD techs who find a dual-screen setup to be to their advantage.

Weird... I though I replied to this a long time ago. I actually had two monitors at one point, but lost one to the paint shop for their paint matching/mixing computer. Once I'm able to order another monitor, I'll make sure it has DVI ports and use it as my main monitor.
