Great for Videos and browsing
Size: 32-inch, Size: 32-inch
I did not buy this for gaming. I wanted a second monitor to browse while playing video games. With that being said it has great picture and doesn’t have any issues with refresh or delivering crisp picture quality. YouTube videos at 4K resolution is almost perfect. Its functions are user friendly and not complicated at all. The stand is rather long because of it being 32” and curved but it is strong and stable. It was super simple to connect and had no issues with compatibility with my PC. I wouldn’t use this for gaming especially if your running a high performance GPU. I’d spend a few hundred more for a better performing monitor

Great Monitor, poor VESA mount.-Updated
Size: 32-inch, Size: 32-inch
Great Monitor, love to give it five stars except for the non-standard VESA mount. The VESA mount plate just won't work with out major modification, or a adapter bracket that slots into were the stand is connected. Then there is the fact that the cheapest adapter on amazon is on sale for just slightly less than half of what I paid for my dual arm stand. I'm not a monitor expert so I can't speak to any technical aspects, but I can tell you I love it . Its crisp and the details with full ray tracing look amazing. Got one for the wife as well She's got a 9070xt GPU and I'm running a RTX3080 and this monitor does them full justice as far as my eyes can tell. Update: I was going to just live with the stand for this thing...Thing is my desk faces an open room, with dogs, Cats and grand kid the potential for my monitor to fall of the desk was too great. So first I was going to buy an adapter but wouldn't you know, I can't find one. Samsung can't even manage to have the same VESA mounts on their own monitors. So pictured is my own adapter, No problem, just a drill, jigsaw, circular saw, some spare long VESA screws, wood screws, and a piece of reclaimed 3/4 inch plywood and a bit of foam padding (for spacing just a little insurance that the wood screws wouldn't get though to the monitor) Tempted to drop the rating to 3 stars but I really like the graphics on this thing. Would I buy it again...Not sure, I love Samsung products but I don't want to go though this little adventure again.

Great for the price!
Color: Avocado Green
It is quiet and it works well. I was trying to purchase a smaller keyboard my husband had picked up for me for my birthday. Although this is much bigger, it works well is quiet and it didn't cost a fortune. The color of the keyboard was not exactly what I was going in for, however I am grateful to have another keyboard as I had ruined another one with coffee. The keyboard is fairly lightweight although like I said I was trying to get a smaller one to replicate the one my husband got me my mistake has decent responsiveness, mouses ergonomic. It's a nice keyboard I wouldn't have gone with this color personally. Seems to be fairly durable and easy to connect and use. The price was very good so I would recommend two others.

Very quiet and comfortable keyboard
Color: Black
I recently purchased this keyboard and mouse set to replace my old one, and I’ve been very pleased with it so far. The keyboard keys are soft, responsive, and surprisingly quiet, which makes typing much more comfortable. The mouse also has a smooth, soft-touch feel that fits nicely in the hand. Overall, the set feels well made and like a great value for the price. I would definitely recommend it to anyone looking for a comfortable and reliable keyboard and mouse combo.
