Owner of several OLED TV models for many years, so I pretty much knew what to expect.
Positives:
Incredible contrast, as expected, and impressive latency and smoothness in fast motion for a monitor.
The HDR is amazing in movies and reaches 1000 nits in small areas when the HDR high setting is enabled.
Beautiful, slim design with nice materials, and it includes a convenient USB-charging remote control.
The Tizen interface is fantastic and fast, allowing you to watch Netflix, Disney, etc. without a PC, or play cloud games like Nvidia. The speakers are also quite good for their size.
Now let's move on to the negatives:
The menu is overly complex, with 4 different menus: one for the TV, one for settings within Tizen, another when using the PC mode, and a different menu for the game mode. I have never seen a worse menu ever.
The Samsung warranty does not cover burn-in (they informed me via email).
There is noticeable flicker when VRR is enabled (see Rtings video). The screen menu has two VRR options: one default option called G-sync/FreeSync, and another GPU VRR option that fixes the flicker but introduces stutter. In other words, you can't avoid the flicker unless the FPS is locked, which is silly in my opinion.
Unfortunately, the panel has quite a few reflections, as you can see in the photos (no problem when it's dark).
When there is content with a black background and the room is lit, the panel turns purple, as shown in the photo. Essentially, there is no anti-glare coating, so it's not ideal for use in bright environments.
Unfortunately, I can see the QD OLED fringing in text (no problem in games or movies). It stands out, especially when I have it next to an IPS panel that I use every day. However, those who have QD OLED panels have gotten used to it (just like they got used to the poor black levels, and those who switched from IPS to OLED).
The brightness is very low (the maximum is 50 in SDR), and it barely reaches 230-240 nits. In comparison, my IPS panel easily reaches 450 nits. It's like day and night when the content is full-screen and bright, such as watching sports or the sea. In terms of brightness (not contrast), the IPS panel is far superior.
The HDR on Windows is annoying, even after calibration, because I can see that the panel's brightness changes when I open and close windows. It's not as noticeable at 400 nits, but it's very noticeable and bothersome at 1000 nits. So, I just work at a constant 240 nits in Windows SDR, regardless of the window I open.
Now, regarding burn-in and the fact that OLED pixels lose brightness over time, as well as the burn-in protection that shifts the image, I won't consider them negatives since we already know that at some point, whether it's in 2 or 5 years, there will be panel issues no matter what you do.
Overall, I am quite satisfied, and it met my expectations. They didn't magically solve the problems that OLEDs have, nor did IPS and VA panels magically become better. Each has its own use.
And everything depends on the perspective you see them, if you put the OLED to be at night with content with a black background or HDR, it is logical that the IPS next to it will be considered garbage by some. However, when you put a similarly priced IPS panel, for example an Asus Pro Art with daylight and Full Screen Bright content, such as a hockey or soccer match, next to the OLED, then you will be disappointed with the OLED.
So, the QD oled are a great purchase as long as we know what use we will want them for. (I must say that I saw up close a Mini Led monitor from a friend and unfortunately the fan that had to cool the panel made a lot of noise due to its tremendous brightness, but the worst part was the motion in games like CS, PUBG, where there was a lot of blur and ghosting. OLED is the way to go for competitive games, it doesn't have the slightest blur or ghosting.
Ps. In SDR mode, change the Color Space from Native to Auto, this way you will have natural colors (although not as impressive as most people want)
