Is the LG C3 good for PS5 and Xbox Series X?

Yes. All four HDMI ports are 2.1, so you get 4K at 120Hz, VRR and ALLM without juggling inputs. Input lag is low enough for competitive play.

How does the C3 compare with the C4?

The C4 is a little brighter and has a newer processor with better upscaling. The C3 keeps the same panel strengths and HDMI 2.1 features, so it remains a strong pick if brightness is not critical.

Is 48 inches too small for a living room?

It suits bedrooms, small living rooms and desk setups. For a large room with seating far back, a 55-inch or larger set gives a more immersive picture.

Do I need a soundbar?

The built-in speakers are clear but thin on bass. A soundbar or AV receiver improves movie and game audio noticeably, and eARC on HDMI 2 makes the connection simple.

Yes. It uses a standard VESA mount, and the panel is thin enough to sit close to the wall. Plan for the downward-facing ports when routing cables.

Should I worry about burn-in?

Static logos, tickers and game HUDs left on for hours every day raise the risk over years. Mixed viewing and the built-in OLED care settings keep it low for most households.
