VGA connect from PC to TV

I have a VGA port on both my desktop PC and my TV (I believe 15 pin). I am thinking about getting a long (10 ft)VGA cord and connecting my PC to the TV so I can watch movies on full screen on the tv.

Has anyone ever done this? If so what kind of problems can I expect. I believe I will have to set the TV to RGB in order to have the TV act as my monitor. I think for sound on the tv I will have to also get a sound cable??

Is the quality of the VGA cable important?

Information please.

You can get cables off eBay very cheap its simple on the tv set imput to the port normally vga and your good to go you use speakers on pc for sound. Is it an old TV with no options to cast to it.

Caledon Ken, why would you not expect a good picture on the tv?

Samuria, VGA cables are cheap most any place (I am not in any hurry to set this up, I am using PLEX from a Windows 7 pc and that works great as long as Windows 7 is functional. I just want a good back system incase Windows 7 stops working as it does right now (end of life is Jan 2020). It should continue to work long into the future.

I am not absolutely positive, but I believe I have the same audio input on my tv as the output on back of my pc. I should be able connect directly and get the sound from my tv.

Because VGA resolution is not that good.

The maximum standard VGA resolution is low (640 X 480). SVGA is a bit higher (800 X 600). However, there are higher analog resolutions available from most graphics cards (including onboard video) with a 15 pin mini-D connector. Since the OP didn't mention any specs about the PC source or the TV, it's hard to guess what formats would be supported.

I admit that I'm a digital snob. I'd never use analog video if a digital interface was available.

I have a 10ft eBay VGA cable on my TV that I occasionally use for connecting laptops etc. Although the TV is full HD the maximum wide screen resolution it will accept on the VGA input is 1360 x 768 & the cable works fine at that. Yes you will need a separate audio cable.

One of my pcs is on VGA 1.5m cable and works fine at 1920x1080 60Hz. That's using onboard video on a rather old MSI B85-E45.

Being analog, I think VGA resolution drops with long cable runs.

Have you not got HDMI ports on TV and PC?

I use a DVI to VGA adaptor With a GTX1060 on an oldish 24" non HD TV, Used as a monitor for one of my PCs 1920x1080 @ 60Hz, could only get 1440 x 990 using HDMI to HDMI no available settings in the TV to change or improve anything.
From experience, from a few years ago now, for long VGA cable runs, anything over around 3 or 4 metres, you used to need a much higher quality low loss cable or use a low resolution such as 800x600, possibly these days it may not be a problem however better to check!
