I bought a cheap 4k UHD android tv from a local company which supports HDR. But, whenever I watch any HDR movies on it, the screen becomes really dark and unwatchable on daytime. But if I watch the movie with HDR turned off, the color looks washed out and the same movies 1080p non HDR version even looks better. Is there any way to fix it? I generally use mxplayer or vlc to play videoes on my Android TV
There is nothing to fix. Your TV is cheap, therefore cant display hdr properly. If you try watching HDR content without hdr supported hardware, it also gonna look bad. Your options are, either keep watching dark hdr movies, or stop watching hdr content.
