I bought Ridaex Nuke based on my friends recommendation. After purchasing the TV I was scared and concerned about the quality.
Its been 6 months using it, now I feel its really worth buying.
The 4k picture quality is the best what I personally feel. It has something called ImageMagik picture engine which enables to switch from SDR to HDR mode. Which makes the picture even crisper.
Look wise it looks pretty standard.
