VS Other Brands

When comparing the TCL 65P638K with other brands, it stands out as a strong contender in the smart 4K TV segment. TCL has established itself as a reputable brand that offers value-for-money products with impressive performance. The 65P638K provides a feature-rich experience with its Android TV platform, voice control capabilities, and compatibility with various devices. Its picture quality, HDR support, and gaming experience compete favorably with other brands in the same price range. However, users may find subtle differences in software interfaces, design aesthetics, and brand-specific smart features when comparing them to other leading TV manufacturers.

Value for Money

The TCL 65P638K offers excellent value for money, especially considering its competitive price point compared to other smart 4K TVs of similar size and specifications. Users get a feature-packed television with 4K Ultra HD resolution, HDR support, and access to the Android TV ecosystem, providing a vast selection of apps and content. Including voice control and Google Assistant further enhances the overall user experience. The TV’s gaming capabilities, multiple connectivity options, and calibration features make it attractive for casual viewers and tech enthusiasts. For those seeking a high-quality smart 4K TV without breaking the bank, the TCL 65P638K delivers exceptional value.

Size Options

The TCL 65P638K is available in 65-inch screen size, ideal for large living rooms, home theaters, and spaces where viewers want to experience the immersive nature of a big screen. This size offers a cinematic experience, making it suitable for watching movies, sports events, and playing video games. However, it’s worth noting that TCL may offer this model in other screen sizes as part of its product lineup. Users who prefer smaller or larger screen sizes may explore TCL’s other TV models with various size options to suit their preferences and room dimensions.

4K Resolution

The TCL 65P638K features a 4K Ultra HD resolution, providing four times the pixel count of Full HD TVs. This translates to exceptionally sharp and detailed images, making every scene come to life with clarity and realism. 4K resolution enhances the viewing experience, especially for larger screen sizes, where the pixels are less visible. Users can enjoy 4K content from streaming services like Netflix and Amazon Prime Video, as well as compatible 4K Blu-ray discs and gaming consoles. The TV’s support for High Dynamic Range (HDR) further elevates the picture quality, delivering enhanced contrast and vivid colors for a more immersive entertainment experience.

8K Resolution

It’s important to note that the TCL 65P638K is a 4K Ultra HD TV and does not support 8K resolution. As of the TV’s release, 8K resolution is typically found in high-end premium models from select manufacturers. While 8K TVs offer an incredibly detailed image, it’s worth considering that 8K content is still limited, and the price point of 8K TVs is considerably higher than 4K TVs. For most users, a 4K Ultra HD TV like the TCL 65P638K provides an excellent balance of picture quality, features, and value, making it a practical choice for most consumers.

HDR Technology

The TCL 65P638K boasts High Dynamic Range (HDR) technology, significantly enhancing the TV’s picture quality by expanding the contrast and color range. HDR allows the TV to display a broader spectrum of colors, making images more vibrant and lifelike. Dark scenes appear richer with deeper blacks, while bright scenes pop with intense highlights. This results in a more immersive viewing experience, with visible details in shadows and highlights. The TCL 65P638K supports popular HDR formats such as HDR10 and HLG (Hybrid Log-Gamma), ensuring compatibility with a wide range of HDR content from streaming services, Blu-ray discs, and other sources.

OLED Technology

Contrary to OLED technology, the TCL 65P638K is not an OLED TV. OLED (Organic Light Emitting Diode) technology employs individual self-emissive pixels that can produce their light, allowing for precise control of brightness and contrast at the pixel level. This results in perfect blacks and infinite contrast ratios, as each pixel can be turned on or off independently. OLED TVs are known for their excellent picture quality, wide viewing angles, and slim designs. However, OLED technology is generally more expensive than traditional LED TVs, and the TCL 65P638K utilizes a traditional LED panel.

MicroLED Technology

At the time of the TV’s release, MicroLED technology is not featured in the TCL 65P638K. MicroLED is an emerging display technology that utilizes tiny, individual LEDs to create a picture. MicroLED technology offers pixel-level brightness control like OLED, leading to exceptional contrast and color performance. MicroLED displays can achieve higher brightness levels than OLED, making them ideal for bright environments. However, as a newer and more premium technology, MicroLED TVs still need to be expanded in availability and are typically more expensive than LED and OLED TVs.

QLED Technology

The TCL 65P638K is not a QLED TV but an LED TV with advanced picture technologies. QLED (Quantum Dot Light Emitting Diode) is a proprietary display technology developed by Samsung. It utilizes quantum dots, tiny semiconductor particles that can enhance the color performance of LED-backlit LCD panels. QLED TVs offer a wider color gamut, better color accuracy, and improved brightness compared to standard LED TVs. However, it’s essential to note that QLED is specific to Samsung’s lineup, and TCL employs its advancements in LED technology to achieve excellent picture quality in the 65P638K model.

Ambient Mode

The TCL 65P638K features an Ambient Mode, which allows the TV to blend more seamlessly into its surroundings when not in use. When activated, Ambient Mode displays images or patterns that match the wall behind the TV, effectively camouflaging it. Users can select from pre-loaded images or use their pictures for a personalized touch. Ambient Mode is a practical feature for those who wish to minimize the presence of a large black screen in their living space, transforming the TV into a functional and aesthetic piece of art or decoration.

One Connect Box

As of the TV’s release, the TCL 65P638K does not have a One Connect Box. The One Connect Box is typically found in some Samsung QLED models. It allows for easier cable management and clutter reduction by housing all the TV’s connections in a separate external box. Instead of having multiple cables directly connected to the TV, users can connect their devices (such as gaming consoles, Blu-ray players, and soundbars) to the One Connect Box, which then connects to the TV with a single, more manageable cable. While the TCL 65P638K lacks this specific feature, it does offer an array of input ports at the back of the TV for seamless device connectivity.


As with any smart TV, the TCL 65P638K will receive software updates in the future. These updates, delivered over the air, will ensure that the TV remains up-to-date with the latest features, improvements, and security patches. Users can expect ongoing support from TCL to optimize the TV’s performance and enhance its capabilities over time. Additionally, as the Android TV platform continues to evolve, the TCL 65P638K will benefit from new app releases and expanded content offerings through the Google Play Store, ensuring a future-proof entertainment experience.
