Is the Titan S100 75-inch good for gaming?

It is fine for casual console play, but nothing in the specs points to HDMI 2.1, 120Hz or variable refresh rate. Competitive gamers should look at sets that list those features.

Does it have local dimming?

No local dimming is listed. It is an edge-lit QLED, so dark scenes will show more glow than mini-LED or full-array sets.

What smart apps does Titan OS have?

Titan OS carries the major streaming apps, but its catalog is smaller than Google TV or webOS. Check that your must-have apps are available before buying.

Can I mount it on a wall?

Yes, it is a standard flat-panel TV that takes a VESA wall mount. Use a bracket rated for a 75-inch set and check the VESA pattern on the back panel.

Does it support Bluetooth headphones?

Bluetooth is built in, so you can pair headphones or a soundbar wirelessly. Wired HDMI eARC is still the better choice for a full surround system.

How does it compare with the S100's smaller sizes?

The 75-inch version shares the same 4K QLED panel technology and Titan OS as the rest of the S100 line. The larger screen suits bigger rooms but shows more glare and needs more wall space.
