I am aware that there are answers regarding this but they do not seem to answer it for me.

A few years back I got a Acorn Electron and it works using the arial for video fine, but I would like to connect it to my monitor which has a VGA & HDMI input.

Is there a cheap converter or cable I can buy without me having to make something to convert one of the outputs on the electron to VGA/HDMI?

Thanks

    As Tommy states, modern VGA monitors won't work without extra hardware. But you can use a SCART adapter cable to connect RGB to a TV or monitor with a SCART input. Since you're in the UK these TV/monitors should be readily available - you may already have one - and here's a cable that Tommy has already linked to. If you need more info I'll add an answer. – Nick Westgate Mar 28 '17 at 22:18

The Electron outputs an analogue interlaced 625-line image, with a line rate of 15.625Khz.

HDMI is a digital input, so cannot comprehend the Electron's analogue output.

VGA is analogue but many monitors expect a line rate of 31 kHz. It's not impossible that your screen would be okay with 15.625Khz though, as that's the PAL standard, so you could at least have a try. The pinout of the Electron's monitor port is here and a passive cable would work if your screen is compatible. I guess you'd need something like this, this and this.

Failing that, you'll need a scan doubler, which does exactly what the name says, taking a 15.625Khz input scan rate and outputting 31.25Khz, which is within the range VGA screens expect.

It cost me something like $50 all up to connect my Electron to the TV using an RGB to SCART cable (this one from eBay) and an RGB to HDMI converter like the one pictured below:

You can get this model from a bunch of different eBay sellers, under various different brand names, but they're all the same. I've tested it out with MODE 0 - MODE 6, and it seems to consistently work well. It also works well with my BBC Model B The only time I've seen it fail is when playing Firetrack on the Electron, which does some tricky stuff with the video output to get more colours.
