Yes, you can get confirmation that the 65" version of the Samsung S90D available in Europe and Switzerland uses a QD-OLED screen. Unlike other sizes such as 48", 55", 77" and 83" which use conventional OLED screens, the 65" models in the S90D series in Europe are equipped with QD-OLED panels.
It is not possible to connect a wireless headset with a USB transmitter directly to the TV, as the Samsung S90D does not provide specific support for such USB headset transmitters. Instead, you can use Bluetooth headphones that can be paired directly with the TV. The S90D supports connection with up to two Bluetooth headphones simultaneously, providing a convenient solution for wireless audio output.
The Samsung S90D OLED TV supports Dolby Atmos for an immersive sound experience. However, it does not come with a built-in Dolby Atmos sound system like a dedicated soundbar. For enhanced Dolby Atmos sound, pairing it with a compatible soundbar is recommended. The TV itself features a 2.1 channel speaker system with 40W output, but for a full Dolby Atmos experience, additional equipment is needed.
The Samsung QE48S90D uses a WOLED panel.
For desk mounting, you can use monitor arms designed for TVs, but ensure they are compatible with the weight and size of your TV. Look for arms that can handle at least 10.60 kg and are suitable for a 48-inch screen. Some popular brands include Ergotron and Chief, but always check the specifications to ensure compatibility.
The Samsung QE77S90DAEXZU uses OLED technology, not QD-OLED. OLED stands for Organic Light-Emitting Diode, which allows for individually controlled pixels to produce pure blacks and bright whites, enhancing contrast and picture quality. QD-OLED, on the other hand, combines quantum dots with OLED technology, but this specific model does not use QD-OLED.
According to the current official manufacturer information, the 2025 Samsung OLED TVs support G-Sync, but G-Sync is not explicitly listed for the QE48S90DAE (S90D, 2024) model according to the available product data. G-Sync is not mentioned as a feature in your product specifications and the official announcements refer to the 2025 models.
I'm not entirely sure if your model supports G-Sync. The information I have does not clearly cover this. For a definitive answer, I recommend checking the manual or the official Samsung website.
The Hz number is not the mega decisive factor... often this is used as a sales argument... the picture is mega and I can readjust all picture settings even in professional mode... the brightness is brilliant, we have a 20 m window front facing south and the TV is in the north, so to speak... nevertheless the picture is mega good even in economy mode (less power consumption)... by the way, our eyes can realise less than 20 Hz... more is genetically not possible... so even 60 Hz would be sufficient...
The Samsung QE55S90DAE (2024) and the Samsung QE55S90C (2023) have beberapa important differences, which are listed here:
## Picture quality and brightness
- The 2024 model, the S90D, offers slightly increased brightness compared to the 2023 S90C, which is particularly useful when viewing HDR content.
- Both models use QD OLED technology, but the newer models such as the S90D benefit from small improvements in image processing and brightness.
## Processor and technology
- The S90D is equipped with the new Neural Quantum Processor 4K, resulting in better image processing and faster TV operation. In contrast, the S90C uses an older processor.
## Audio and additional functions
- The S90D comes with a Dolby Atmos certified speaker system, which provides a better audio experience. The S90C also has good audio, but it is not Dolby Atmos certified.
## Firmware and updates
- Historically, Samsung may have better firmware updates and more stable software support with the S90D compared to the S90C, although this depends on the specific experience.
## Overall performance
- Both TVs offer excellent gaming functions, including low input lag and support for VRR and ALLM. However, the S90D offers slightly better performance in picture rendering and a higher refresh rate, especially when used with a PC.
### Which device is better and why?
The Samsung QE55S90DAE (2024) is better than the QE55S90C (2023) in many aspects:
- It offers higher brightness and better image processing due to the new processor.
- It has a better audio system with Dolby Atmos support.
- It benefits from the latest technologies and improvements in the software.
However, the decision also depends on your specific needs, especially if you are already satisfied with the functions of the S90C and see no need for the newer improvements.
