Sharp GK4245K 70-inch TV: A Budget-Friendly Option for Gaming and HDR Content
The Sharp GK4245K 70-inch TV is making waves in the market, offering a compelling balance of features and affordability. This TV is particularly impressive for its picture quality, making it an attractive choice for gamers and HDR content enthusiasts on a budget.
Picture Quality
The Sharp GK4245K delivers brighter-than-expected HDR pictures, with crisp and punchy highlights that make HDR content look natural and engaging rather than dull. Despite its low price, it maintains good shadow detail and minimal greyness in dark scenes, providing a fairly consistent viewing experience across light and dark content. The TV supports multiple HDR formats including HDR10, HLG, and Dolby Vision, which is rare among budget TVs, enhancing its versatility for HDR content. However, it does not fully realize the full dynamic range of HDR and may not have sophisticated HDR tone mapping. Some slight imperfections occur, such as a tendency for colour clumping in dark scenes or subtle tonal gradation loss, meaning blacks and dark colours are not perfect.
Connectivity
The Sharp GK4245K features typical modern smart TV connectivity with several apps supported through its TiVo software platform, including popular streaming services and UK broadcasters. However, it lacks HDMI 2.1 ports, which limits advanced gaming and high-bandwidth connectivity options, particularly relevant for next-gen consoles and high-frame-rate content.
Audio Performance
The audio system, designed with input from Harman Kardon, provides sound projection that extends beyond the TV’s physical size, improving immersion for its built-in two-channel speaker system. While the audio is decent for a budget TV, it is still recommended to add a soundbar for a better overall sound quality and experience, especially for movies and music.
Summary
In summary, the Sharp GK4245K 70-inch TV stands out as the best cheap 70-inch TV available for those prioritizing picture quality on a budget, but falls short for enthusiasts who need advanced connectivity and high-end audio. The TV offers access to most UK broadcasters' content through Freely and is the first 70-inch TV to be recommended in the best cheap TV guide. However, it does not have HDMI 2.1 connectivity, which is yet to become standard on cheap sets. A soundbar, such as the Sony HT-SF150, is recommended to improve the audio quality of the Sharp GK4245K. The pictures of the Sharp GK4245K are substantially brighter than expected, resulting in crisp and punchy highlights within HDR pictures. However, the TV has some backlight clouding issues, especially during dark scenes.
