Good overall brightness, great color gamut and good sound quality the tv speakers don't get very loud but the sound is clear. Movies scenes appear true to life. The build quality seems fair, the television is thin so it feels flimsy when handled. I'v paired it with the HW-Q850D 7.1.2 CH SOUND BAR attached with a USX MOUNT Universal Soundbar Mount, Sound Bar TV Bracket(Amazon). The sounbar extends about a half inch on both sides. I'm very pleased with the purchase

Bought this tv as an upgrade from my Old LG TV specifically for PS5. The picture is awesome and the 144htz refresh rate is nice, it’s got a lot of bells and whistles.

Love this tv. I watch a lot of sports and the picture is gorgeous. I was going to buy a soundbar and i still might but I am surprised the sound is so good as is. I have it set high on top of a dresser in bedroom. Also love the central pedestal stand! Always hated those little “feet” on other tvs. I put the stand on a little towel and I can swivel it easily to change the viewing angle. We also like all the streaming options that Samsung offers from the home page. Lastly, the remote works the cable box and the cable remote works the tv. Win win!
