Is a 24-inch Full HD TV good enough for a bedroom?

Yes. At 24 inches the 1080p panel is sharp at normal viewing distance, and the size suits a bedroom, kitchen or dorm. The main limit is audio, so plan on a soundbar for louder rooms.

Does it work with a Samsung soundbar?

Yes. Q-Symphony syncs the TV speakers with compatible Samsung soundbars so both play together. Other soundbars connect over HDMI or Bluetooth but without that combined mode.

Yes. It uses a 100 x 100 mm VESA mount and weighs 2.5 kg without the stand, so most small wall brackets will hold it. The stand adds about 17.5 cm of depth when used on a surface.

The TV, its stand and the standard accessories: remote, power cable and quick setup guide. HDMI and other cables are not included.

Does it have Bluetooth and Wi-Fi built in?

Yes. Wi-Fi handles streaming and Bluetooth pairs headphones or speakers, and there is an Ethernet port if you prefer a wired connection.

Is it a good gaming TV?

It is fine for casual console play, but it is a 60 Hz Full HD panel without the high refresh and HDMI 2.1 features of Samsung's gaming sets. Serious players should look at a larger, faster model.
