TCL Roku Rocks
Love love love this 75 inch TCL TV! My niece introduced me to this brand in Dec 2019 when she bought me a 50 inch TCL SmartTv for Christmas and its a great tv with a crisp picture and great sound! So when I remodeled my living room I got the 75 inch TV in July and I can not get enough of this tv might should have gotten a 85 inch instead!

Read if you are on the fence..
I put a solid amount of time into purchasing a 75 inch 4k tv. A few of the negative reviews on here almost pushed me away completely. A tv in this price range is absolutely amazing! I have a high end 60 inch 4k Samsung as well. There are things you need to consider before you purchase. Reviews says this TCL doesn't get bright at all, but it'll also depend on the room setting and lighting that shines in. My bay windows are off to the side, and I see very little glare off the window directly across from the tv. If your room is very bright, you may want to spend much more on 4k TVs that get extensively bright. But I also went into the picture settings and tweaked them to where I have the brightness and clarity just about perfect. I also added a 4 year warranty for $99 on top of a greatly priced $700 75 inch Roku TV. That's hard to beat! I also changed my speaker settings to "Theatre" and switched it to Dolby Surround and I was pleasantly surprised! I don't even need my soundbar honestly. I wrote this to help some out that may be where I was. Make sure you check your room environment, and understand you're looking at the 4 series. Of course it won't compete fully with $3000 4k tvs, but to be honest, with the tweaking I did I can't tell a difference. They say the TCL 6 series gets a bit brighter, so if you have the money, you may want that. I'm completely happy with the 4 series! Good day!

Excellent buy. Perfect picture and sound. It's super easy to navigate thru the add ons such as Netflix. Mounted perfectly on the wall. This is my second TCL. Purchased the 65 inch for the bedroom and the 75 inch for the family room. I would definitely purchase over the other brands again.
