Causes and fixes for poor 4K IPTV image quality:

Low bitrate: Some providers label channels 4K but stream at 8–12 Mbps instead of 20+ Mbps. Ask your provider for actual stream bitrate.
Software decoding: Switch to hardware H.265 decoding in player settings — software decoding introduces compression artifacts.
Upscaled HD: Many “4K” IPTV channels are native 1080p upscaled by the provider. True native 4K sources are limited.
Bad HDMI cable: Use a certified HDMI 2.0 cable. Cheap cables cause macroblocking.
TV sharpness too high: Reduce to 0–20. Excessive sharpness creates artificial halos.
Wrong color space: Set HDMI color space to YCbCr 4:2:0 in box display settings.
