VGA Cable Length

Can work. Or not. I used the same 20m cables on same screens, but from different PCs. Worked on the one, and not on the other. Both were IPCs from Siemens. The higher speced one worked.

I ended up buying extenders to make the other work. So good luck. Your GPU will determine if it’s gonna work I think.
 
Why are you going for a 20m VGA cable, via an HDMI adaptor, when most modern computers / laptops, PC monitors (and TV's as well) already come with HDMI inputs included?

Just get a 20m HDMI-HDMI cable and skip the VGA option entirely. (as an added bonus, you also get digital audio feed included in HDMI, whereas you need to run a separate analogue audio cable as well when using the VGA cable option).

You could also run a 20m Cat5e/6/6A/7 RJ-45 LAN cable, using 2 x HDMI to RJ-45 converters, from the output device to the monitor input.

Other HDMI solutions also include using wireless transmitters, coaxial cable or even fibre optic cable as well.

Obviously either the monitor or PC does NOT have HDMI...
 
What about a long HDMI cable and a short VGA cable? Or am a talking cwap?

One is digital, the other is not. You cannot just use an adapter. It has to be a converter, which needs to be powered.

I don’t think he would have asked if he could do that. In 2018 I still bought computers( well, IPCs) with VGA as the primary video output.

As far as I understand most of them uses the HDMI +5 V and does not other source of power?
 
Rather run the full length with HDMI and add the VGA adapter right at the end.
1920x1080 is close to the max resolution of VGA as well (1920x1200). It can either work, but will depend on the quality of the converter and the cable.

I think(possibly wrong) you can go hdmi to vga no power(like the adapter you linked), but vga to hdmi needs power:unsure:
 
a CCTV installer told me you get a hdmi joint to joint the cable, when asking to see one he did not have any.
