Kailangan ba branded yung cable or pwede yung mura lang basta "high speed"? Ano tell-tale signs that I'm getting an HDMI cable that could do 4K? Ano pinakamura na cable na ganun?
Sir, I think basta Hi-speed hdmi kahit mura basta buo (meaning walang putol or loose connection)... At dapat yung file ay 4K...(maybe i'm wrong but that's my opinion).
best to get from reputable brands -- pinaka mura nakita ko is Monoprice brand. as for its output performance, I cannot comment since I haven't used it. may nagbebenta naman nyan dito sa PDVD. so either you ask the seller or you should just trust the brand name and see its performance for yourself
if you're not going to watch 4K movie materials, you won't need high speed HDMI cable. HDMI v1.4b should be good enough... but by cheap ones nor unbranded ones? go with reputable brands parin, of course..
I think if 4K yung TV mapo-process nya rin yung USB files mo...at kung may dedicated 4K media player ka baka mas may dagdag na processing or picture enhancements pa, thereby mas finer picture ang result (provided na magandang klase 4K media player)
I have NVIDIA Shield as external media player. I also play 4K movies via USB movie function ng TV (both LG & Sony). with my untrained eyes, not very much difference on picture quality whether via NVidia Shield (using AudioQuest Pearl HDMI v2.0b) or via TV's USB movie function.
I use the NVidia Shield more often since I watch 4K movies with Atmos/DTS:X audio. other than that, you should be good only using your TV's USB movie function.
HTH!
