I've been LG's TV customer for the last 12 years and I was looking an upgrade for my 55" 3D LG TV without expense to much money. Since last year I read that 55" serie P of TCL was one of the best TV only below of best OLED and premium brand's TV, so since then I was a follower of TCL. So, basically I was decided to buy 65" serie 6 of TCL with some concerns about quality issues, google assistance connectivity, roku system (since I never owned a TV with roku), and also quality of the image since I saw this TV in display at best buy store, even do, I bought it. Quality of TV's frame: It looks so good and great quality in finish. Looks nice in my TV room. Remote Control: It is very small and looks cheap, however its functionally is excellent. I'm ok, but could be more roust. Roku TV system: My first time with this software, and Wao! very friendly user interface, so fast to load applications... Now I really love Roku's system. This TV is ready to use google assistance due last Roku's software update. Sound: I read that sound is very bad, but to my this is not an issue because I have 7.2.2 home cinema, even do, to be honest sound of the TV is good comparing with most of the TVs. Obviously is not comparing with home cinema or sounds bar, but I ok with TV's sound. Image quality of streaming videos: Wao, wao, Image looks incredible (see pictures attached). I streaming some 4K's videos from you tube and its amazing. specially those videos with HDR. If you try, just be aware that you will need an internet connection of at least 20 Mbs so see real 4K videos. I realized that you can see videos at 1440P with DHR but this is not real 4K image...but again, just make sure you select video quality to 4K. Image quality of 1080P BluRay: I was complete surprise of the significant improvement of regular HD into this TV. Obviously is not a 4K image quality, but comparing with my last HD 55" TV, it is a big improvement. I guess this TV has a great up-scaling feature. At this point of the review I will not see bluray's 4K movies yet, but hopefully in a couple of days I will receive my new 4k player to see it in dolby vision! In conclusion: Amazing image, amazing system (Roku), great product without any quality's complaint so far. I'm very excited with this purchase. If you want to have the same results than I, just make sure that: 1. Buy HDMI cables version 2.0 which is for 4K tv's. 18 Gb speed. 2. If you have home theater, make sure it has support for HDMI for 4K (HDCP 2.2). 3. Your internet connection speed needs to be at least 20Mbs if you want to streaming real 4K. 4. Buy 4K player with dolby vision feature. 5. Buy 4K movies with HDR dolby vision.. Juts be aware that most of the movies has HDR 10, but the best is HDR dolby vision (most of the news movies has it). 6. Enjoy, enjoy, enjoy
