My Lenovo thinkstation S20 only came with a VGA port for my 22 inch 1680x1050 resolution screen. I've found that now with all the 1080p video editing I do as well as graphics editing with adobe fireworks I'm really low on screen space.

I've had my eyes on a Dell U2713HM for a while now which is a 27 inch screen that has a 1440p resolution. I would use it mostly for video editing/rendering, video watching, programming and gaming. I would lower the resolution to 1080p for gaming though as my NVIDIA Quadro FX 3800 probably wouldn't game well at 1440p.

Problem is that I heard VGA either doesn't support 1440p or it displays it poorly. I heard DVI is heaps better than VGA since VGA is analogue and DVI is digital. I have a VGA to DVI adaptor... could I plug that into my VGA port and get the higher resolution and better image quality or does it not match the quality of a real DVI port to monitor connection?

A 3rd option would be buying a display port cord as I have noticed my computer has a display port but no DVI port. Would a display port be better than DVI for 1440p video editing and 1080p gaming?

I'm lost here... what should I do? Is there an even better 1440p monitor for gaming? The highest I'm willing to spend on a monitor is $1,200.

Your GPU is just a tweaked GeForce card as the quadro series are the same as their gaming counterparts except they have different drivers. If I were you I'd check out Eizo's monitors as well I've heard great things from them. Also I'd buy a new workstation card if it only has a VGA port.

also I've heard that you can modify a regular consumer nvidia card (say a 780) and make it run on the quadro series drivers. I don't know much about that though as I've never tried.

It's not actively converting the signal, so you get the same quality picture if you use the adapter. Does your Quadro not have a DVI port? Displayport would be just fine for 1440p editing and gaming.

And 1600p would be even better for editing, and both 1440p and 1600p are well within your budget. You could even buy a new 780 and a 1440p monitor for gaming ;)

The Thinkstation specs say, you have a NVIDIA® Quadro® 600, PCIe x16 adapter, 1GB,
one DisplayPortTM, one dual-link DVI-I ? Take a closer look please. And I'm pretty sure, the VGA-to-DVI adapter is in fact a DVI-I-to-VGA adapter. It only work the other way round.
The Dell U2713 is a good choice! Connect it with a DP ore the included DVI-cable. For the budget, you can even go for an U3014 with way more screen space instead.

Thanks for your help guys. I've just found out that Display port is more modern and better than DVI. I will go buy a display port. Also note that my Lenovo think station was $7,000 (in Australia stuff costs more due to high tax) and its heavily modified with 12 gig of ram, 12 cores with a 3.33ghtz xeon processor and 4.5 TB of hard drive space across 3 harddrives.

Anyway, thanks for your help I will definitely go with the display port as VGA and DVI is the old stuff...
