General discussion

vga cable and image size

May 3, 2010 10:41AM PDT

Hi:
I just bought a 50-ft VGA cable (15-pin) for a renovation I'm doing on my house (going to wire projector into ceiling). I'm currently using a fairly short (~6ft) 14-pin cable to connect my computer (Gateway laptop running windows XP) to my Mitsubishi HC1500 projector. That configuration worked fine. However, when I hooked my new cable up to test it (before burying it in a wall and a ceiling!) there is a problem with the image size. The edges of the computer's desktop are not visible on the projector's image. Dropping it down to 1024x768 works, but degrades the image quality on my laptop's screen.

What's the problem? Would a different cable (shorter, or some other number of pins) allow me to keep things as they were?

Thanks,
David

25 ft?

Thanks for your reply, R:
What I really needed was a 30' cable, but all I seemed to be able to find was 25' or 50' so I went for 50'. Would a 25' solve it, do you think? That might just reach...

Cheers,
David

To solve.

We need an active solution like I listed. There are others. Yes, a 25 foot would help but is not a sure solution. Today I find folk that will not accept "might work" solutions. Which means I move directly to sure solutions.

Notice this unit does 1080 displays at 100 foot?

Thanks Bob!
'Course, the "might work" solution costs about 1/10th as much as the sure solution, so that might make it worth a try...

Best,
David
