The video explores the concepts of refresh rate and frames per second (FPS) in the context of modern TVs. Refresh rate, measured in hertz (Hz), denotes how frequently a TV screen refreshes per second, while FPS indicates the number of video frames displayed each second. Higher refresh rates, like 120Hz as opposed to 60Hz, generally contribute to smoother motion but are often misrepresented in marketing. This misinformation can lead to confusion regarding the actual performance improvements. The segment explains that a mismatch between frame rate and refresh rate can cause motion issues like judder, with techniques like "three-two pull down" utilized to address these discrepancies.
The video further discusses the advantages of 120Hz TVs, particularly in gaming contexts with consoles like the Xbox Series X and PS5 that support 120 FPS content. With HDMI 2.1, more 120 FPS content is anticipated, allowing for 4K images at higher frame rates. Benefits of 120Hz TVs include improved frame interpolation, enhanced motion smoothing, and support for variable refresh rate (VRR) technologies to eliminate screen tearing in games. VRR formats such as AMD FreeSync, NVIDIA G-Sync, and HDMI VRR are described, highlighting their relevance and compatibility with different devices. The speaker advises viewers to verify TV specifications to avoid deceptive marketing claims and encourages those needing further assistance to comment for help.

In this segment, the video differentiates between refresh rate and frames per second (FPS). Refresh rate, measured in hertz (Hz), indicates how many times a TV screen refreshes per second, while FPS refers to how many frames of video content are displayed per second. The video highlights that a higher refresh rate typically results in smoother motion but cautions against confusing this with marketing claims that may exaggerate refresh rates. Most modern TVs have either a 60Hz or 120Hz refresh rate, where higher-end models often feature 120Hz, although this doesn’t guarantee better motion handling due to the significant role of response time. The video explains how mismatch between frame rate and refresh rate, such as a TV displaying 24 FPS content at 60Hz, can cause motion issues like judder. Techniques like “three-two pull down” are used to align frame rates with refresh rates to minimize such issues.

In this segment of the video, the discussion covers the benefits and importance of 120 Hz TVs, especially in comparison to 60 Hz models. It explains that while 120 Hz TVs can display each frame five times, making panning shots smoother, there are few sources outside of gaming consoles like the Xbox Series X and PS5 that utilize 120 FPS content. With the advent of HDMI 2.1, the availability of 120 FPS content is expected to increase, enabling TVs to display 4K images at this higher frame rate. Additionally, 120 Hz TVs are advantageous for their ability to interpolate frames more effectively, improve motion smoothing, and support variable refresh rate (VRR) technologies to prevent screen tearing in games. Various VRR formats exist, including AMD FreeSync, NVIDIA G-Sync, and HDMI VRR, with compatibility details for different TVs and gaming devices highlighted. The segment also addresses misleading marketing practices surrounding TV refresh rates, urging viewers to check the actual TV specifications for accurate information.
