Projector and PC

Hi, there seems to be a lot of very smart and experienced people on this forum. Here is my problem. Hopefully, someone can give me advice on this.

I have an ATI Radeon 9800 based PC with the max resolution of 1920x1200. It has 1 DVI and 1 VGA output. The DVI output is connected to a 24in widescreen monitor at the max resolution and has been working perfectly. I would like to keep it as is.
However, I just got a Sony VPL-HS51 projector. The projector has many inputs including HDMI and VGA. Based on its manual, it supports the max setting of 720/50p via HDMI and 1280x720 via VGA.

What I need an advice on is about the best way to connect my PC to the projector (for the best picture quality). My PC is my only enterntaiment center - I currently watch DVD's on the DVD-ROM drive. Hence, I want the best picture possible. Also, I am now looking to buy a HDTV tuner card to watch digital over-the-air programming on my PC.

I currently have four reservations: (1) if I were to use DVI-HDMI connection, the displayed PC desktop would be of very low resolution on the projected screen (although movies might be fine), Plus I would probably have to purchase a new video card with dual DVI outputs (2) if I were to use the VGA-VGA connection, I would get an analog and not digital picture of 480p when watching DVD's and 1080i when I buy the tuner card, (3) I would strongly like to keep the current DVI-digital widescreen display connection in place, (4) The projector is about 25ft away from the PC. So, I will need a 30ft cable to connect the two.

What is the most optimal connection for me to get the best possible quality out of my PC?
Should I consider buying a new dual DVI video card? Is the price tag of ~$200 for 30ft DVI cable really worth it?

Many thanks!

I am suprised that Stewart didn't advise you on the Gefin splitter. That might be worth a look. You can get a DVI splitter, alowing you to connect 2 displays to your computer output. You may have to try a direct connection to the projector first, if your computer is set for MAX resolution, and the projector can't downconvert it then you will have issues.
All you need to do is connect the cable you have right now, put the projector on the floor or somewhere close, fire it all up and see if you get a picture.
There are other companies that make these type of splitters out there, should not be too hard to find one, AV tool box, Extron, Kramer are a few I can think of that should have something.
If all this doesn't work, then back to the old VGA connection, which still should look very good.
Good luck

I would use VGA for the projector, since your run is 25'+ DVI has problems on longer runs it's best 15' or less. I've used VGA on 100' runs no problem.
The video quality between vga and DVI is VERY, VERY close.
I'm using a 21" CRT monitor set at 1280x1024 over VGA no problems. I hook this PC to MY HD-CRT-RP TV with DVI some times and watch some WMV HD encoded DVDs at 1080p.
And this is only Nvida 5200 with 128mb, not nearly as good as you ATI 8500. John
