Questions and answers
- Which is better for dark-room movie nights?
- The LG B3. OLED turns pixels off for true blacks, and it supports Dolby Vision and Dolby Atmos. The Samsung's LED backlight can't match that contrast.
- Which is better for gaming?
- The LG B3. It has a 120 Hz native panel, VRR, G-Sync and FreeSync Premium, and four HDMI 2.1 ports. The Samsung DU7200 is limited to 60 Hz.
- Is the LG B3 worth the extra money?
- If you care about contrast, HDR and gaming, yes. At $1,149.00 versus a $361.82 low on the Samsung, you pay roughly triple for a clearly better picture.
- Which has more HDMI ports?
- The LG B3 has four HDMI 2.1 inputs. The Samsung DU7200 has three.
- Which is better in a bright room?
- The Samsung DU7200. Its LED panel reaches higher typical brightness than the B3's 240 nits, which can look dim in a sunlit room.
