Is a 100-inch TV too big for a normal living room?

It needs a wall at least 8 to 9 feet wide and a viewing distance of roughly 10 to 14 feet for comfortable 4K viewing. In a smaller room it will dominate and may look overwhelming.

Does this TV need a special wall mount?

Yes. A panel this size is heavy, so use a mount rated for its weight and fix it into studs or a reinforced wall. A professional install is worth considering.

How does Neo QLED compare with OLED?

Neo QLED uses a mini-LED backlight, so it gets brighter and has no burn-in risk. OLED gives deeper per-pixel blacks and better off-angle viewing, but OLED panels this large are rare and costly.

How many HDMI ports does it have?

It offers HDMI inputs for consoles, a soundbar and a streaming box, though fewer than some rivals at this tier. Plan a soundbar or receiver if you have several devices.

Is it good for gaming?

Yes for casual and console gaming, with 4K and HDR support. Serious players should check the measured input lag and whether all ports support the highest refresh rate.
