42x is the skyworth box ..I am pretty sure pvr box will give better qualityPvr hd upgrade box gives more picture clarity Than tata sky hd box? iam using old tata sky hd model 42xx . These pics from that box
You will never know until you use a good quality stb..back in 2015 era there was Technicolor card box which had excellent quality even better than binge+ but as time progressed they introduced inferior quality cardless hevc boxes starting from panna box ..so people who bought connection after that will never realise the max quality until they use old boxes or use binge+ box, this pvr box also I feel have similar quality like old Technicolor box
