I took a gamble on this TV, and it was more worth it than I could have predicted
5/5
I bought this because I previously had a samsung QLED TV which failed (49" Q6 from 2018) and I nearly went for the latest version of the Q6 again, but decided to look up professional reviews of TVs to see which was the best value.
TCL was a name I'd not heard of before, but I saw a lot of praise for their C745 series among various reviewers and decided to investigate; whilst I couldn't find the 745 in the right size for me, I saw the C805K was available and was quite impressed by the specifications of the hardware as well as the price not being too expensive.
I am EXTREMELY impressed by this TV: the picture quality is excellent, with the HDR10 (with a higher brightness than most competitors, at 1350 nits) and mini quantum LED (essentially QLED by another name for legal reasons) combining together to create excellent scenes with deep and rich colours along with spectacular contrast, and the backlight micro-dimming is a big step up from Samsung's edge-light dimming, which can leave the center of the screen to suffer from poor contrast.
Setup was very easy if you have an android phone and google account, because you can simply download the Google Home app (I already had this for a Google Nest speaker) and then with a few button presses on your phone it sets up your TV with no fuss and even adds in your accounts for the most popular apps like Netflix, Amazon Prime and Disney+ if you've logged into them on your phone before
I primarily use my TV as a second monitor for my high-end PC, and it is perfect for this due to the added game mode feature, where it utilizes a high 144Hz refresh rate and variable refresh rate (VRR) technology to provide extremely fast and responsive scenes with no input delay and no screen tearing when V-sync is off, this along with the HDR10 and the high local dimming means games look especially beautiful on this screen, to the point where I've been playing more games lately on my TV rather than my computer monitor just because it makes them look so nice.
Overall I highly recommend this TV, I felt like I was taking a gamble by buying it over a known brand like Samsung, LG, or Sony, but after using it for a while I believe that those big companies have gotten complacent and stopped putting as much effort or technology in their products and just rely on their name to carry them, and this TV is a prime example of that in action, as I feel like it blows away it's nearest price-competitors from those brands
