TxTaz,

Thank you for sharing your review. If a menu setting on your TV is grayed out, it typically means the option is not currently available based on the input source, specific feature settings, or connected devices.

In many cases, grayed-out settings appear because a streaming app like Netflix or Hulu is running in the background. To resolve this, press and hold the Return button on your remote to fully exit the app. Then return to the settings menu – your options should now be accessible.

Here are a few other reasons a function may be unavailable:
• Picture Mode may be grayed out if HDR+ is enabled.
• Zoom and Position is only available when Picture Size is set to Custom - not 16:9 or 4:3.
• Certain options may also be disabled while content is actively playing from a specific source (e.g., HDMI or app).

If the image isn’t meeting your expectations, there are several adjustments you can make to improve your viewing experience.

First, please ensure your TV is running the latest firmware, as updates may include important picture quality enhancements. Go to: Home > Left directional button > Settings > Support > Software Update > Update Now

Then, select a Picture Mode that best fits your environment: Home > Home > left directional key > Settings > All Settings > Picture > Picture Mode
1. Standard – Default mode for general viewing
2. Dynamic – Brighter and clearer in well-lit rooms
3. Eco – Optimized for energy saving
4. Movie – Best for watching in dark environments
5. Filmmaker Mode – Preserves content exactly as intended by creators

You can also enhance your experience by enabling AI Mode, which automatically adjusts picture and sound based on your surroundings and usage patterns: Settings > All Settings > Advanced Features > AI Mode Settings > AI Mode

If these adjustments don’t improve your picture quality, feel free to contact Samsung Customer Support at 1-800-SAMSUNG, available 8AM – 12AM EST, 7 days a week. You can also LiveChat with an agent or find helpful guides by visiting the ‘Support’ section of our website.

Hi,

Thank you for sharing your experience with the internet connection on your Samsung QN90F TV. Whether you're using Wi-Fi or a wired (LAN) connection, there are a few steps you can take to help resolve the issue:
1. Power Cycle Your Equipment. Unplug both your TV and router/modem from the wall outlet. Wait at least 30 seconds, then plug them back in and allow both devices to fully restart.
2. Check the Network Status. On your TV, go to: Home > left directional key > Settings > All Settings > Connection > Network > Network Status. This will help determine if the issue lies with the network or the TV.
3. Try a Different Connection Type. If you're using Wi-Fi, try connecting an Ethernet (LAN) cable directly from your router to the TV to test the connection. If you're using a wired connection, try switching to Wi-Fi to see if the issue persists.
4. Reestablish the Network Connection. Go to: Settings > All Settings > Connection > Network > Open Network Settings, and follow the prompts to reconnect to your Wi-Fi or wired network.
5. Update Firmware. Software updates can often resolve network bugs. To check for the latest version: Settings > Support > Software Update > Update Now

If these steps don't resolve the issue, we’d be happy to provide further assistance. Please call Samsung Support at 1-800-SAMSUNG, 8AM - 12AM EST, 7 days a week. LiveChat is also available at the ‘Support’ link on our website.
