Based entirely on an idea I saw at this event, (John G7JTT had one on show) I picked up a Dell laptop screen for free from a local advert. A recommended supplier https://rover.ebay.com/rover/0/0/0?mpre ... 3614348146 delivered a new driver board for £20 and a few minutes saw it connected up and working on my Linx Windows tablet (duplicates the screen), my laptop on D-plug lead (as a second monitor screen) and my spare Portsdown RPi (pictured). I found if I connected the big screen power AFTER the RPi has booted, both gave full screens but if the RPI booted with the HDMI screen powered, the HDMI became 2/3 full size (RPi screen stayed full size on the RPi).
Given that my local PC shop told me that they 'chuck out' dead laptops every couple of months I think it's worth pursuing again. This is, I guess, an early 2000's screen, later driver boards may be able to support composite video in too as did Johns example.

All good stuff and 12v DC or less too

Glad you got it working can be a cheap option for a nice size screen Must order one of the new driver boards that has DVBS inputs as well.

All best John G7JTT
