Is the curved screen worth it over a flat OLED?

The curve is mostly cosmetic on a 55-inch set. It adds a slight wrap for one or two close viewers but can catch reflections and distort the image from the sides. A flat panel is the safer pick for most rooms.

How does it compare with newer LG OLEDs?

Newer C-series sets are brighter, support HDMI 2.1 features like 120Hz and VRR, and have newer webOS apps. The C6 still matches them on black level and viewing angles, but it is a weaker choice for gaming and bright rooms.

Yes, it handles HDR10 content, but peak brightness is limited, so highlights look restrained compared with modern OLEDs and bright LCDs. Dark-room viewing shows it at its best.

What 3D glasses does it use?

It uses passive polarized 3D glasses, and two pairs ship with the TV. Any standard passive 3D glasses, including cinema ones, should work.

Yes. It uses a standard VESA mount, and at roughly 13 kg without the stand it is light for its size. The curve means the edges sit slightly forward of the center.

How many devices can I connect?

There are three HDMI inputs and three USB ports. A soundbar plus a console and a streamer fills the HDMI ports, so an HDMI switch helps if you have more devices.
