I have purchased Samsung TVs for Myself, Family and Friends for many years. None of the dozen plus units have purchased has ever failed to function nor please.
The picture on this 55" S90D is Stunning! and the Menu interface with the Remote is user friendly and setup was a breeze when adding all devices I connected to the set.
The Smart Things App is Solid as I also added my Samsung Q900A Soundbar with the added Rear Surround Speakers. Now, I do wish that the mounted stand had about a 1/2" more gap opening from the TV so the Soundbar could snug in a little under the TV.
As always, I expect many years of Quality Enjoyment! from this Samsung TV :) Highly Recommend.

We love this TV. Bought it to replace a LG 55" LED tv we bought back in 2019. It went out and i hated LG TVs after the frist year we owned it so i moved on to Samsung (They make my phone and my fridge so why not?)
First up is the picture. WOW! it has so much brightness and clarity to it that its more like looking through a window than watching TV. Wishing it had an anti glare film but that cost much more. This beautiful screen is thin like a mirror though. First time ever having to follow instructions on how to remove a TV from the box.
Second, apps open fast and app store is easy to navigate. Our 2019 LG couldnt run Paramount Plus because it wasnt in the LG app store without an update and a TV thay was only a year old was not supported with updates anymore (last one was 2018). Since this TV has Google Store for apps, pretty sure it'll be supported for a long time. Easy to navigate menus. It even set itself up to control my Sony Blu-Ray player thats connected through HDMI port, not wi-fi.
Third, sound. Sound is great coming out of this TV but volume varies from app to app as well as show to show. So setting it tonthe volume you like on netflix might be too loud on hulu or to soft on Fandango.... weird but nothing to drop a star on.
Fourth, the remote. It has a USB-C port to charge it as well as a solar panel on the back! That was cool, no more searching for batteries BUT i worry about when the battery in it does go out and how long do i have before that happens?
All and all, great TV. Was it worth the price? Yes, for under $2k, this is a great TV. Great enough that a teenage boy has trouble staying away from it.

This TV is absolutely stunning. QD OLED takes it to another level. The vibrancy and brightness of the colors is amazing. HDR content is just so lifelike and 3 dimensional. I’m an LG guy normally and own a 77 inch C3. I approve of this product.

55”. 4K OLED. Native 144hz. True Black. I genuinely couldn’t find something to complain about with this TV if I tried. The picture is incredible. The remote is an upgrade over the B series from 2022. The interface is responsive. Bluetooth is reliable if you pair an Xbox controller and use GamePass. I absolutely love this TV and it’s up there as one of the best purchases I’ve ever made. I had buyers remorse after buying the Q80B. I would buy this TV over and over again.

This is an unbelievable television. The display is equally brilliant in bright or dark rooms. ThisTV replaces an old plasma Samsung in our bedroom and compliments an LG TV in our living room. I was instantly in love with the Samsung remote and interface. So much more intuitive and easier to navigate bathe LG. I also prefer the Samsung internet channels.

A:AnswerFrom what I've been able to tell, the differences on the S90D vs the S90DD are the same as the S90C and S90CD.
The S90CD/DD are warehouse only TVs, so that means Sams Club, Costco, etc... And the S90CD/S90DD have 60W RMS speakers.
The S90C and S90D are available everywhere else retail, and the speakers in the TV are 40W RMS.
