Last Saturday, I bought a TCL 43P6 4K HDR for bedroom use. I bought it at Anson's for PhP 21,500.00.
Here are my feedback/observations:
Picture Quality is great. I am not an expert, and I haven't bought any HDMI 2.0 cables yet for my PS4 Pro. I have yet to upgrade to Apple TV 4K. So my only true gauge is the native Netflix app and the UHD shows there like The Haunting on Hill House. It looks gorgeus on 4K HDR.
Only 2 HDMI ports, and as far as I can tell, neither is ARC-capable HDMI 2 is ARC. I am just not sure if Dolby pass thru will work. I hope so, because the options in the settings for audio are Auto and PCM only. Maybe Auto is for pass thru?
The analog input is 3.5mm but it comes with a free3.5mm to RCA adapter.
There is no analog out, but there is optical out and bluetooth. And since I connect via analog to my Creative 2.1 speakers, I had to buy a DAC.
Speaking of audio out, the only choices are Auto and PCM. I have no idea what Auto is, because PCM is the only other option. My HISENSE TV has PCM, DD, and DLP.
Built-in speakers sound terrible. I have a Toshiba LED TV, a HISENSE LED TV, and a Panasonic Viera Plasma TV. They all sound decent. TCL sounds really bad. You will want to output the audio to external speakers.
GUI looks like crap and there's no way to even slightly personalize it. There are so many built-in and installable apps but they are all useless (except for Netflix and YouTube). PBA apps and CNN apps have not been updated in a year.
The only choice for country in the setup is Philippines, as all the other choices are non-English speaking countries.
The remote control looks terrible. It is thinner and longer than usual. Button layout is unintuitive. There is a Netflix button but no YouTube button.
So in summary, it lacks a lot of features, apps are crap, but picture quality is great and the price is unbeatable. I wish TCL just skipped on the "Smart" TV functionalities and just added features like ARC and DD/DPL output.
