What is true of this model and changes how you fix it
- Panel — Mini-LED ULED QLED2024 mid Mini-LED QLED — bright with good local dimming, fewer zones than the U8N so slightly more blooming, far more than the 60 Hz U6N. Backlight, so some halo is normal.
- Smart platform — Google TVGoogle TV. Not a Roku TV.
- Gaming / HDMINative 144 Hz with HDMI 2.1, VRR, ALLM and FreeSync Premium Pro, plus Dolby Vision gaming — strong gaming at its price. Supports Dolby Vision, HDR10+, HDR10 and HLG. Enable Game Mode.
- What owners run intoReports include crashes of apps, color that looks off in a Vivid mode and an eARC soundbar that stops working.
- How to approach a faultRestart the TV, clear the cache for a failing app and set the picture mode.
- Finding your modelThe model number is on the back label and in Settings, System, About.
- Apps and storageThe TV has limited storage, so remove apps you do not use and keep a gigabyte free. Clear an app's cache before reinstalling it.
- SoundbarsConnect a soundbar to the eARC port and enable HDMI-CEC. If the sound is missing, set the digital output to PCM to test.
- Picking the right picture modeChoose Filmmaker or Theater for films, Game for consoles and Standard for general use. Avoid Vivid, which oversaturates. If the picture looks dim, check energy-saving settings and the ambient light sensor. Adjust one setting at a time and judge in your usual room light.
- Keeping the picture settings tidyEach input stores its own settings, so adjust the input you use most. Keep a note of your chosen settings and photograph the settings screens so that you can restore them after a reset. If colors look wrong after an update, reset the picture and start again with a mode that suits the content.
- Accessories that suit itA soundbar with eARC gives the best sound, and an Ultra High Speed HDMI cable is needed for a console at a high setting. A wall mount needs the right VESA pattern and a stud, and a stand that matches the feet suits a cabinet. Replacement remotes pair easily, and the Google Home app can work as a backup remote. Keep the TV ventilated and use a surge protector.
