The gaming experience on the LG LED UR91 4K Smart TV is crucial for those who enjoy playing video games. Here, we assess the TV’s gaming capabilities, including input lag, refresh rate, and support for gaming features.

Input Lag and Response Time

Low input lag is vital for gamers who demand quick response times. The LG LED UR91 aims to provide a responsive gaming experience, minimizing the delay between controller input and on-screen action. This is essential for competitive gaming and fast-paced gameplay.

Refresh Rate

A high refresh rate is desirable for gaming, contributing to smoother motion and a more immersive experience. While traditional TVs often have a 60Hz refresh rate, LG’s gaming-oriented models may offer higher refresh rates, such as 120Hz or 240Hz. A higher refresh rate can make fast-paced games feel more fluid and responsive.

Gaming Modes and Features

LG often includes gaming-specific modes and features to optimize the gaming experience. These modes can further reduce input lag, improve motion handling, and enhance picture quality for gaming. Investigate whether the LED UR91 offers such features to improve your gaming sessions.

Viewing Angle

The viewing angle is essential for TVs, particularly if you have a large seating area or if the TV is placed in an open living space. LG’s IPS (In-Plane Switching) panels often provide wider viewing angles than traditional LCD panels. This ensures viewers enjoy a clear and consistent picture quality even when seated off-center.

Voice Control

Voice control is a growing trend in smart TVs, offering convenience and hands-free operation. LG’s smart TVs often support voice commands, allowing users to search for content, adjust settings, and control the TV using voice prompts. Voice control adds a layer of ease and accessibility to the LED UR91’s user interface.

Input Ports

The availability and types of input ports are essential when considering connectivity for various devices. The LG LED UR91 is likely equipped with multiple HDMI ports, USB ports, audio jacks, and other inputs to accommodate gaming consoles, Blu-ray players, sound systems, and streaming devices. Ensure the TV has the input options to suit your home entertainment setup.

Wall Mount Compatibility

If you plan to mount the LG LED UR91 on the wall, verifying its wall mount compatibility is crucial. Look for VESA mount standards, which ensure you can use standard wall mounts to install the TV securely. Wall mounting can save space and provide a clean and modern look.


Calibration options allow you to fine-tune the TV’s settings to your liking. LG’s TVs typically provide various picture modes, color adjustments, and audio equalizers for customization. Calibration features can significantly impact your gaming and viewing experience by tailoring the TV’s performance to your preferences.

Software Updates

Regular software updates are crucial for maintaining the TV’s performance, security, and compatibility with new features and content formats. LG often provides consistent software support and updates for its TV models. Ensure that the LED UR91 benefits from timely and reliable software updates to ensure its long-term usability.

In The Box

When purchasing the LG LED UR91, closely examine the box’s contents. In addition to the TV, the package should typically include the remote control, batteries, stands (if applicable), and any necessary cables for setup. Confirm that all essential components are included.

VS Other Brands

To make an informed decision, it’s essential to compare the LG LED UR91 4K Smart TV with similar models from other brands, especially if you have specific gaming requirements. Evaluate factors like gaming performance, viewing angles, voice control capabilities, input options, wall mount compatibility, calibration features, and software support. Comparing the LED UR91 with offerings from competing brands can help you determine which TV best suits your needs and preferences.

Size Options

The LG LED UR91 4K Smart TV is available in various size options to cater to different room sizes and viewer preferences. Standard sizes typically include 43 inches, 55 inches, 65 inches, and 75 inches. The right size is crucial to ensure an immersive viewing experience that fits your living space.

4K Resolution

The LG LED UR91 boasts a 4K Ultra HD resolution, providing a display with 3840 x 2160 pixels. This higher Resolution offers exceptional clarity and detail, making it ideal for watching 4K content, such as streaming services, UHD Blu-ray discs, and gaming. With four times the pixel count of Full HD, it delivers sharper images and a more lifelike visual experience.

8K Resolution

The LG LED UR91 is a 4K TV that does not support 8K resolution. However, it’s worth noting that 8K TVs were emerging in the market but were less widespread and affordable than 4K TVs at that time. If LG has since released an 8K version of this TV, it would offer an even higher level of detail and picture quality.

HDR Technology

High Dynamic Range (HDR) technology is a pivotal feature that enhances the TV viewing experience. The LG LED UR91 is expected to support HDR, which extends the range of colors and provides more excellent contrast between dark and bright scenes. This results in more vibrant and true-to-life visuals, deeper blacks, and brighter highlights.

OLED Technology

LG is renowned for its OLED (Organic Light-Emitting Diode) technology, which delivers stunning picture quality. OLED panels offer individual pixel control, resulting in perfect black levels and exceptional contrast. Each pixel can be turned on or off independently, leading to vibrant colors and infinite contrast ratios. If the LG LED UR91 incorporates OLED technology, it would excel in picture quality.

MicroLED Technology

MicroLED technology was an emerging display technology that offered benefits similar to OLED but without the risk of burn-in. LG primarily uses OLED and LED-LCD technologies in its TVs, so it’s essential to check if the LG LED UR91 features MicroLED technology, as it would represent a significant advancement in display quality and durability.

QLED Technology

QLED (Quantum Dot Light Emitting Diode) technology is another advanced display technology that enhances color accuracy and brightness. While LG’s premium TVs often feature OLED, they may also have QLED variants. QLED displays provide a wide color gamut and are known for their bright and vivid colors.

Ambient Mode

Ambient mode is a feature that allows the TV to blend into its surroundings when not in use. LG’s TVs often include this feature, allowing you to display artwork, photos, or information on the screen, turning it into a digital picture frame. Ambient mode is excellent for minimizing the visual impact of the TV in your living space.

One Connect Box

The One Connect Box is a feature commonly associated with Samsung TVs. It’s a separate box consolidating most of the TV’s connectivity options, including HDMI and USB ports. This setup reduces cable clutter and simplifies installation by connecting only one cable to the TV.


Considering the rapid pace of technological advancements in the TV industry, assessing the LG LED UR91’s future readiness is crucial. This includes its ability to receive firmware updates, support for emerging technologies, and compatibility with new content formats. Ensuring your TV can adapt to the evolving home entertainment landscape is essential.
