Great upgrade for ManCave!!
I recently purchased 75' Neo QLED a few weeks ago during early black friday deal since I was upgrading from 55' because it looked small in mancave. I happen to stumble across this TV on Black Friday in store for the same amount & bigger TV. I'm glad i did, my only issue was I had to have it delivered this time because it would not fit into my suv. In-store exchange was easy. The hardest thing was finding the right full motion mount for '24 stud. I pass through receiver w/ 2.1 hdmi cables & run fiber optic audio. I really like the game mode on this TV. Game play ps5 no lag is smoother & faster w/120 refresh. I watch movies in 4k with 4k player & movies are crystal clear (hdr10+) on amazon firestick!! I like the feature w/ amazon alexa when someone rings my doorbell, video will pop up on screen. Set-up was easy through smartthings app, especially since I have samsung ecosystem: phone, tablet, tv, 4k player, etc. Happy I made the upgrade!! :-)

Awesome TV and excellent Best Buy customer service
This was my first OLED and I am very impressed; plus the screen size is perfect for our new home theater. This was definitely the "icing on the cake" for finishing up the home theater project/remodel. Best Buy was great to work with. I originally had a different kind of TV arrive and it was broken in the box, and Best Buy was awesome to work with on getting it sorted out. I ended up returning the broken TV and exchanged it for this one instead, and I am very happy. I'm impressed with the Best Buy staff on how they helped answer my questions and helped me with getting the other tv returned. Back to the TV review, this TV is very clear/sharp, has very black contrast and with the picture being so realistic while watching movies, it's almost like you can reach out and touch the object that you're watching; it's truly an amazing TV. We've been a fan of Samsung TVs for many years, in fact we have one Samsung TV that is 11 years old and still works, so we know we made the right decision to go with Samsung. I'm running my sound through a receiver for home surround sound, but while I was testing everything I just temporarily used the built-in speakers that come with the TV, and I'm very impressed with how good it sounds given how thin this TV is. Thank you again Best Buy, your customer service made this a very pleasant experience.

Samsung SD84
I recently got the Samsung SD84, and I’m really happy with it! I managed to snag it during a sale, and the discount was fantastic—it made the decision so much easier. Here’s what I think after using it for a bit: What I Love: 1. Amazing Picture Quality: The 4K resolution is super sharp, and the colors just pop. Watching movies or shows feels like a mini cinema experience, especially with HDR. 2. Sleek and Stylish: The TV is super slim and looks great in my living room. 3. Easy-to-Use Smart Features: All my favorite apps (like Netflix and YouTube) work smoothly. What Could Be Better: 1. Sound Is Just Okay: It’s fine for regular TV, but the speakers don’t have much bass. I’d recommend getting a soundbar if you want that full audio experience. 2. Still a Little Pricey: Even with the discount, it’s not cheap, but I think the quality makes it worth it. Overall: I’m super happy with my purchase, especially because I got it on sale! The picture quality is the best part, and the smart features make it really easy to use.
