What is true of this model and changes how you fix it
- Panel — OLEDVIZIO's OLED (the only self-emissive TV in its range): perfect blacks, no backlight, so a bright-window dim is the Auto Brightness Limiter, not backlight bloom. A very different picture-fault diagnosis from VIZIO's LCD models.
- Smart platform — SmartCastRuns SmartCast, VIZIO's own platform, with Chromecast built-in and AirPlay 2 and WatchFree+ channels — not Roku, Google TV or Tizen. Update at Settings › System › Check for Updates; casting is the primary way to add content the built-in apps do not cover.
- Gaming / HDMIA 120 Hz panel with two HDMI 2.1 ports, VRR and the ProGaming Engine, plus Dolby Vision. Put the console on an HDMI 2.1 port and enable Game Mode / Auto Low Latency.
- Adding appsSmartCast has a fixed set of built-in apps. If an app is not built in, you add it by casting from your phone or using an external streaming device.
- GamingA 120 hertz panel with two HDMI 2.1 ports, VRR and the ProGaming Engine, plus Dolby Vision.
- A dark pictureOn an OLED, a dim picture is usually a mode, an energy setting or a dark room, since the TV limits its brightness on large bright areas.
- Settings that darkenEco mode, automatic brightness and ambient light settings lower the picture. They can be turned off in Picture settings.
- A different build from VIZIO's LCDsThe OLED-H1 is VIZIO's OLED, with self-lit pixels, so there is no backlight to adjust and no blooming. A dim picture is handled through the OLED brightness and the energy-saving settings.
- Gaming and HDMIThe OLED-H1 has HDMI 2.1 ports for a console at 4K and 120 hertz. A console that does not reach that rate should be set to its enhanced output and connected to one of the ports labeled for it.
- Panel careAs with any OLED, avoid leaving a static picture for long, and let the TV complete its refresh after use. A faint mark that does not fade after a few days needs a call to VIZIO.
