Would such a long VGA extension cable work?

[lostinisaan]

I'm planning to buy a TV with a VGA connection and want to connect my PC to it. The problem is that the TV's about ( going through the ceiling and down to the TV) 7 meters away.

I know that certain USB cables have a limit, but hows that with a VGA cable? Would I get the full signal to the TV if the cable is about 7 meters long?

Thanks for any useful answers.

Make sure it is a VERY high quality, multiple shields, ferrites, etc. It will be thick and heavy. I tried 10 meters once with a standard constructed cable and it was useless. Got a high quality one and it was successful. Another option is a wireless A/V system, not too expensive.

Depends on the resolution. For anything above about 1600x1200 or so, 7 metres is pretty marginal.

Wireless AV senders are a pain, with a lot of interference issues.

I'd consider using something to stream the media to, like Apple TV or Chromecast, or maybe just use an android box dedicated to the TV.

Another option is a VGA extender/booster. They have VGA to CAT5 (Ethernet cable) which can extend to substantial lengths.

VGA

Like Dual-Link DVI, VGA accommodates many resolutions, each of which requires a different amount of bandwidth. As cables get longer, the available bandwidth decreases and with it the highest potential display resolution is lowered. A short VGA cable can manage 1920x1080 without trouble. A long VGA cable may top out at 1024x768, and our longest offering may struggle to reach 800x600.

Basic VGA: For a single cable, it's always important to consider your requirements and the installation environment before opting to use a VGA cable over 5 or 10 metres.

//edit - BTW, my previous comment using 10 meters was quite a while ago when full HD was not common and my plasma TV had VGA at 800x560 resolution and as I mentioned it struggled with it.

There are VGA to Cat5 converters out there. You get two, one that plugs into the computer and one that plugs into the TV (each VGA). Each of those has an Ethernet port. Those will go about 250 feet (75 meters) with Ethernet cable.

I am surprised that you want to use an outdated analog VGA connection to feed your TV.

All modern graphics cards have HDMI output and up to 12 meter cables are available.

You get digital quality video and audio in the same connection.
