If you have a 128/+2/+2A/+3 then you can get or make a RGB to SCART cable. Retro Computer Shack is a great place for trustworthy cables. Ian makes sure they have resistors inside with the correct values for the model, whereas a cheap no-name cable may not be so carefully designed. Make sure you pick the cable for the correct Spectrum model, as they are not interchangeable:

RGB-SCART can be further converted to HDMI if you need that. I have one of these, and it works well:

SPECTRA is an external interface for 48/+ models, that outputs an RGB-SCART signal:
