OLED and QLED screens differ fundamentally in the way light and colour are generated: OLED pixels *light themselves* and can be switched off individually (perfect black, high contrast), while QLED is an LCD panel with quantum dot layer and backlight (strong brightness and vivid colours). Samsung offers QLED/Neo-QLED as a particularly bright, long-lasting option with quantum dots; OLED scores with viewing angles and deep black values. Key differences and practical implications: - Black level and contrast: OLED achieves perfect black because individual pixels can be switched off completely; QLED requires backlighting and therefore does not usually achieve quite the same level of black (with Mini-LED/Neo-QLED, contrast is significantly better thanks to finer segmented dimming). - Brightness: QLED/Neo-QLED can achieve higher peak brightness and is better suited for very bright rooms or sunlight compared to TV. - Colours and colour space: QLED uses quantum dots for very strong, stable colours and a large colour volume; modern OLEDs also achieve very wide colour spaces, Samsung now also combines quantum dots in some OLED models. - Viewing angles and uniformity: OLED continues to offer stable colours and contrast from lateral viewing angles; QLED exhibits earlier brightness and colour losses from the side. - Durability and burn-in risk: QLED is based on inorganic materials and is considered to be more durable with a lower risk of long-lasting image residues; OLED uses organic light-emitting diodes, which can burn in under unfavourable conditions. - Design and thickness: OLED panels are often thinner because no large-area backlighting is required; QLED/Neo-QLED can still be built very slim thanks to mini-LED backlights. - Gaming/motion display: Both technologies offer fast response times; OLED has very short response times, QLED/Neo-QLED models offer high refresh rates and high brightness for HDR gaming. Short recommendation for the choice: - If you want the highest contrast depth, best viewing angles and perfect blacks (especially in a dark home cinema environment), OLED is usually the better choice. - If you have a very bright living room, are looking for high peak HDR brightness, maximum colour stability and long colour/brightness retention, QLED/Neo-QLED is more suitable. I am sure of this based on the manufacturer and technical information that explains the technical principles and advantages/disadvantages of both technologies.

- The technical installation is super simple and easy. You need some manual experience and tools to mount it on the wall. - We don't have a wall in between and the connection is perfect. - The power cable is still there, of course.

The wall bracket included is the same as the WMN-B50EB/XC Slim Fit. I ordered the stand without knowing that it was included, so I returned it. And the stand is fine, the TV is stuck to the wall. However, beware of the picture quality! I'm disappointed. You can see the pixels around people and text. I don't have that with my other Samsung 65' curved TV.

No, you cannot connect your Sonos soundbar directly to the Samsung The Frame Pro QE65LS03FW via the micro HDMI connection. This connection does not support eARC or ARC, which is required for audio transmission via HDMI. Instead, the audio connection is made via the Wireless One Connect Box supplied with the TV. This box has an HDMI eARC connection that is designed to connect to your Sonos soundbar.
