But at that distance it's going to be troublesome. In fact, I'm going with don't bother. If you want to try, be sure it's not VGA or any VGA to any convertor but some HDMI or DVI digital connection. It's a shame it's past 12 feet in my opinion.

I have a 4 yr. old Dell destop computer that I wish to connect to an "as yet to be purchased" Vizio HDTV. I have checked their "internet apps" HDTV's and they are larger than the space I have for the tv. My next alternative is to connect the Dell desktop to one of their 37" LCD tvs.
I'm not sure what "spec" information you need to determine if this is possible, but here are some specs for my computer:
* Dim E520, Intel Core 2 Duo Processor E6320 (1.86GHz, 1066FSB) with 4MB cache.
* 2GB DDR2 SDRAM at 667 MGz
* NVIDIA GeForce 6150 LE Graphics GPU
* 250 GB SATA II Hard Drive (7200 RPM)
That's a start. I'd appreciate any advice you can provide. The connection between the two devices will be about 15-18'
Thanks,
Charlie
