LG 75UQ7590PUB: A Comprehensive Look
Picture Performance
The LG 75UQ7590PUB offers a satisfactory 4K viewing experience. Its LED display provides decent clarity and color accuracy for everyday content. However, it’s important to have realistic expectations. This TV isn’t designed to compete with premium models. It lacks advanced features like local dimming, which would significantly improve contrast and black levels. If you’re a videophile seeking the deepest blacks and the most vibrant colors, you might want to explore higher-end options. For casual viewers, the picture quality is generally acceptable, particularly in well-lit rooms.
Smart TV Functionality
LG’s webOS platform powers the smart features of this TV. You’ll find access to a good selection of streaming apps, including Netflix, Amazon Prime Video, Disney+, and YouTube. The interface is relatively easy to navigate, although some users have reported occasional sluggishness. The Magic Remote, which allows for point-and-click navigation, can be a convenient way to interact with the smart features.
Audio Output
The built-in speakers of the 75UQ7590PUB are adequate for typical TV viewing. However, they lack the punch and depth of a dedicated sound system. If you want a more immersive audio experience, consider investing in a soundbar. A soundbar will provide a wider soundstage and enhance the clarity of dialogue and sound effects.
Connectivity and Ports
This LG TV offers a standard array of connectivity options. You’ll find multiple HDMI ports for connecting your devices, such as game consoles and Blu-ray players. It also includes USB ports for playing media from external drives. The TV supports Wi-Fi for connecting to your home network and accessing streaming services.

Comparison with Similar Models
| Feature | LG 75UQ7590PUB | Samsung TU7000 (Similar Price Range) | TCL 75S435 (Similar Price Range) |
|---|---|---|---|
| Resolution | 4K UHD | 4K UHD | 4K UHD |
| Smart Platform | webOS | Tizen | Roku TV |
| HDR Support | HDR10 | HDR10 | HDR10, Dolby Vision |
| Refresh Rate | 60Hz | 60Hz | 60Hz |
The Samsung TU7000 and TCL 75S435 are often considered alternatives in the same price range. The Samsung TU7000 uses the Tizen smart platform, while the TCL 75S435 features Roku TV. One key difference is HDR support. The LG and Samsung models support HDR10, which is a basic HDR format. The TCL model adds support for Dolby Vision, a more advanced HDR format that can provide a slightly better picture in some content. Consider which smart platform or HDR format you prefer when making your decision.
Choosing the Right TV for You
Selecting a TV involves balancing budget with desired features. If a large screen and 4K resolution are your priorities, and you’re comfortable with webOS and basic HDR, the LG 75UQ7590PUB is a decent option. If Dolby Vision HDR is important to you, the TCL model might be a better fit. If you prefer the Tizen smart platform, consider the Samsung option. Reading reviews and comparing specifications can help you make an informed choice.
Maintaining Your TV
Proper care can extend the life of your television. Regularly cleaning the screen with a soft, dry cloth is crucial. Avoid using harsh chemicals or abrasive materials. When not in use, consider unplugging the TV to save energy. Protecting it from power surges with a surge protector is also a good idea. Keep the vents clear to prevent overheating.
Understanding 4K and HDR
4K resolution refers to the number of pixels on the screen. It offers four times the resolution of standard high definition (1080p), resulting in a sharper and more detailed picture. High Dynamic Range (HDR) is a technology that enhances the contrast and color range of the image. HDR content can appear more realistic and vibrant. It’s important to note that to enjoy 4K and HDR content, you need a TV that supports these technologies, as well as content that is mastered in these formats. Streaming services and Blu-ray discs are common sources of 4K HDR content.
Initial Setup and Installation
Setting up your LG 75UQ7590PUB TV involves several key steps. These include unpacking the TV, connecting external devices, and configuring initial settings. Proper setup ensures optimal performance and user experience.
Unboxing and Assembly
Start by carefully removing the TV from its packaging. Place the screen face-down on a soft, flat surface. Locate the base parts in the box. Attach the stand to the TV using the provided screws. Tighten them securely but avoid over-tightening.
If wall-mounting, follow the instructions in the user manual for proper bracket installation. Ensure you have the correct VESA mount size for this 75-inch model. Always have a second person assist with lifting and mounting such a large TV.
Once assembled or mounted, position the TV in your desired location. Keep it away from direct sunlight and heat sources. Allow adequate ventilation space around the unit to prevent overheating.

Resolving connectivity issues on your LG 75UQ7590PUB TV can improve your viewing experience. These troubleshooting steps will help you address common problems with Wi-Fi, Bluetooth, HDMI, and USB connections.
Wi-Fi and Bluetooth Issues
To fix Wi-Fi problems, first check your router. Restart it by unplugging for 30 seconds, then plug it back in. On your TV, go to Settings > Network > Wi-Fi Connection. Select your network and enter the password. If it doesn’t connect, try forgetting the network and reconnecting.
For Bluetooth issues, ensure your device is in pairing mode. On the TV, go to Settings > Sound > Sound Out > Bluetooth. Select your device from the list. If it doesn’t appear, turn Bluetooth off and on again on both devices.
Update your TV’s software regularly to fix bugs and improve connectivity.
HDMI/ARC Connection Problems
HDMI connection issues often stem from loose cables or incorrect settings. Check that HDMI cables are securely plugged in at both ends. Try different HDMI ports on your TV to rule out a faulty port.
For ARC (Audio Return Channel) problems, ensure you’re using the HDMI ARC port on your TV and sound system. Enable SIMPLINK (HDMI-CEC) in your TV settings. Go to Settings > All Settings > Connection > HDMI Settings > SIMPLINK.
If audio isn’t working through ARC, set the TV’s sound output to HDMI ARC. Navigate to Settings > Sound > Sound Out > HDMI ARC.
USB Port Malfunction
USB port issues can affect external storage and device connections. First, try a different USB device to determine if the problem is with the port or the device. If the port is faulty, use another available USB port on your TV.
Ensure your USB device is formatted correctly. The LG 75UQ7590PUB supports FAT32 and NTFS file systems. To format a USB drive, connect it to a computer and use the built-in formatting tool.
If the TV doesn’t recognize your USB device, go to Settings > General > Devices > USB. Check if the device appears here. If not, try restarting your TV with the USB device plugged in.
| Connection Type | Common Issues | Quick Fix |
|---|---|---|
| Wi-Fi | Weak signal, incorrect password | Restart router, re-enter password |
| Bluetooth | Pairing failure | Restart Bluetooth on both devices |
| HDMI | No video or audio | Check cable connections, try different ports |

Picture and Sound Quality
The LG 75UQ7590PUB offers several options to enhance your viewing experience. Adjusting picture settings and optimizing sound output can significantly improve your enjoyment of this 4K TV.
Adjusting Picture Settings
To get the best picture quality, start by selecting the appropriate picture mode. The “Standard” mode works well for most content, but “Cinema” mode is ideal for movies. For HDR content, ensure HDR is enabled in the TV settings.
Adjust brightness and contrast to suit your room lighting. In brighter rooms, increase brightness slightly. For optimal 4K viewing, sit about 5-7 feet from the screen.
Fine-tune color settings if needed. If colors look off, adjust the tint slightly. The TV’s LED backlights can be dimmed for deeper blacks in dark scenes.
| Setting | Recommendation |
|---|---|
| Picture Mode | Standard or Cinema |
| Brightness | 50-60 |
| Contrast | 85-95 |
| Color | 50-55 |
| Tint | 0 |
Sound Optimization
While the TV’s built-in speakers are adequate, a soundbar can greatly enhance audio quality. For best results, connect a soundbar via HDMI ARC.
In the TV’s sound settings, choose the audio mode that matches your content. “Standard” works well for most programs, while “Cinema” enhances movie audio.
If using the TV speakers, adjust equalizer settings to boost dialog clarity. Increase mid-range frequencies slightly for clearer voices.
Enable AI Sound Pro for automatic audio optimization based on content type. This feature adjusts sound settings in real-time for an improved listening experience.
