Hi guys
Very happy with my ZX Spectrum now that I am using a video converter to hdmi which gives really a sharp picture On an LCD screen (by the way the Spectrum has the composite mod)
The only issue I have may be this strange waving of video screen especially on bright colored areas as you can see in the brief video.
I do not know if this is normal behavior of RGB on HDMI Hd screen or something is wrong with the ZX hardware.
Quite annoying indeed.
