I use 3ds max, zbrush, and photoshop mostly.

My video card recently went on the fritz, so I went to Fry's to replace it and quickly discovered (I don't really keep up the latest hardware info) that AGP is going the way of the dinosaur. Being that my motherboard doesn't have a PCI Express slot, and I have no intention of replacing my motherboard, CPU, and RAM any time soon, I opted to go with a GeForce 6600 since they offered it in AGP.

I currently have one ViewSonic LCD display, but I'm looking to replace it with two new Samsung 970P displays.

Samsung 970P:

My video card has two outputs, but one's DVI and the other's analog. Looking at the specs for the Samsung 970P it looks like I'm good to go since it does both Analog and Digital, but I'm wondering what the cons are going to be if I do that.

Am I going to be able to take advantage of OpenGL and Direct3D on both displays? Will I be able to do all of my content creation (including 3D) on both displays? Is the screen running in analog going to look horrible juxtaposed against the one being fed a digital signal?

Thanks!

It should be fine, you can do DCC on both monitors as well. The 6600 is able to keep up fairly well. I have 6800 softquad to FX 4000 and it handles dual monitors well.

As for DVI or VGA, buy a $5 adapter from VGA to DVI, it may have came with the card, that well keep the signals that same, I am not sure what the benifits of digital are though I have CRTs and use the adapters.

it should offer you no troubles, you'll see a difference between the digital port and the analog one, because of signal noise, LCDs used to convert A-D poorly, but that's pretty much gone now.

I've heard reports that nVidias can have bandwidth issues on their DVI ports giving poor playback, however I don't have any solid information and use an ATI myself. If you find the digital monitor a bit sluggish, run them both on analogue (your card will come with an adapter) it will help your displays look similar.

Thanks guys.

I obviously can not take an analogue signal and make it digital with a simple adapter/converter. That would be like taking a web res image and blowing it up to make a poster out of it. So Im going to assume that my only option, if I should need to make them the same, would be to downgrade the DVI port with an adapter.

I had heard, at one point, that OGL would only work on one monitor at a time (the primary monitor), but that was a few years ago and it may have just been a limitation of the video card I had at the time.

Thanks again,

For one, you CANNOT go from VGA to DVI without a DAC (Digital Analog Converter). It only goes the other way (DVI -> VGA) And this is only possible on a DVI connection that supports analog (DVI-A or DVI-I) DVI-D does not support an analog signal, and thus will not convert to VGA.

The down side to using an analog connection with a LCD panel is degraded image quality. Since the LCD panel is digital by nature, and the video card is digital, it makes the most sense to use a digital connection. Using a VGA connection causes problems because the signal gets converted once by the DAC found on the video card (to VGA) and then once again by a DAC found on the panel back into a digital signal. As you can imagine this cuases loss of data, and the resulting image may be slightly blurry compared to an image transmitted over DVI (a purely digital experience). This shouldn't be too much of a problem. The image isn't overly distorted in any way, and the quality isn't as bad as an old blury CRT.
