Maybe this is somehow different elsewhere in Europe... :( Especially when using older devices!

(My 19" Samsung LCD definitive needs sync on green via Scart... :D A brand new Toshiba TV works fine with the UNO. But this device is 16:9. I'd prefer the 4:3 Samsung or an other elder TV to use...)

Although the thread is written in spanish, I think it's worth pointing at it, as it was the very first discussion and tests I did with the initial scandoubler for the Spectrum core. Back in 2014, things like modifying the master clock to ensure that all timings remain the same, yet allowing for a greater than 50 Hz vertical frequency, were introduced back in those days (the Next people has just realized this, afaik)
