# Do 8K 120Hz TVs exist? - Canonical: https://33rdsquare.com/do-8k-120hz-tvs-exist/ - Published: 2024-06-26 - Author: Kara Masterson - Categories: [Technology](https://33rdsquare.com/category/tech/) --- If you‘re considering an ultra premium TV purchase these days, odds are 8K and 120Hz refresh rates are high on your wishlist. But can current technology deliver 8K clarity combined with the responsiveness and motion smoothness of 120Hz, all in one package? Let‘s dig into the possibilities and challenges of enabling 8K 120Hz. ## Why You Might Want an 8K 120Hz TV As a gaming and home theater enthusiast, I know you want the ultimate visual experience. 8K resolution provides jaw-dropping clarity with over 33 million pixels, making images look almost real. And 120Hz refresh rates result in remarkably smooth motion for fast-action scenes and gameplay. Combining these technologies would let you see mind-blowing detail in even the fastest on-screen motions. It would deliver the pinnacle of sharpness and responsiveness for truly immersive gaming and movies. ## The Limitations of HDMI 2.1 and DisplayPort 1.4 So why don‘t 8K 120Hz TVs exist yet? In short, current HDMI and DisplayPort specifications top out at bandwidth well below what 8K 120Hz requires. The latest HDMI 2.1 standard theoretically supports up to 48Gbps of bandwidth. But in practice, using full 48-bit 4:4:4 chroma subsampling, it can only handle 4K at 120Hz or 8K at 60Hz. DisplayPort 1.4 has similar limitations. To achieve 8K 120Hz with full 4:4:4 color, a bandwidth over 50Gbps is needed. That‘s simply more than what today‘s TV and media interfaces can provide. ## Displaypanel and Processor Limitations Also a Factor Even with faster interface specs, display processor and panel capabilities pose another hurdle. Pushing 33 million pixels at 120Hz demands immense graphics and image processing power. Today‘s best TV processors like Samsung‘s Neo Quantum 8K chipset can only handle 8K at 60Hz. Enabling 120Hz requires a 2x increase in processing and memory bandwidth that will require next-gen silicon. Likewise, panel response times need to improve to handle the insane pixel switching speed required for 8K 120Hz. Today‘s TV panels typically top out at 4K 120Hz. ## When Will 8K 120Hz Become Possible? The good news is that ultra-high resolution displays capable of 8K 120Hz could arrive sooner than you may think, perhaps in the next 2-3 years. For connectivity, HDMI 2.1a and DisplayPort 2.0 on the horizon promise bandwidth over 80Gbps, more than enough for 8K 120Hz. On the panel side, OLED response times continue improving, and technologies like MicroLED will also enable higher refresh rates. Chipmakers like Mediatek, Samsung, and LG are racing to develop processors and GPUs able to handle the rendering demands of 8K 120Hz. Nvidia‘s latest GeForce RTX 4090 GPU points the way towards being able to drive ultra-high frame rates at 8K. ## Optimal Gaming and Viewing Distance for 8K 120Hz To enjoy the full benefits of 8K 120Hz, you‘ll also need to consider optimal viewing distance. Just like 4K clarity is wasted on smaller TVs, you need a very large screen and to sit reasonably close to appreciate 8K‘s resolution. Experts suggest sitting around 1.5m or closer for an 85" or larger 8K display. At this distance on a big screen, your eye can discern the difference 8K makes, especially with 120Hz‘s increased sharpness for motion. Of course, smaller screen sizes like 65" can still benefit from 8K 120Hz. But the improvements will be less noticeable unless you‘re nearly on top of the TV. ## Advances Like HDMI 2.1a and Display Stream Compression Will Propel 8K 120Hz Forward One of the biggest bottlenecks, HDMI 2.1, is set to level up. The upcoming HDMI 2.1a specification adds support for Display Stream Compression (DSC), a lossy compression technique that can pack more 8K data into the current 48Gbps HDMI bandwidth. DSC allows reducing visible color information while maintaining full luma bandwidth. Combined with chroma subsampling, this makes 8K 120Hz achievable over future HDMI 2.1a cables. DisplayPort 2.0 will offer even more radical bandwidth upgrades to 80Gbps and beyond. It also incorporates DSC for high resolution high frame rate displays. ## The Outlook for Content Creation and Transmission at 8K 120Hz Bandwidth limitations extend beyond cables and ports. Creating and transmitting 8K 120Hz content poses monumental challenges too. Cameras capable of 8K 120fps recording are still bleeding edge and expensive. Top-tier production studios are only now embracing 4K 120fps capture. Distribution networks are also years away from handling streaming at 8K bitrates. However, advances like HFR (High Frame Rate) for cinema using interpolation and frame doubling can help create and deliver 8K 120Hz experiences before end-to-end workflows fully develop. ## Should You Wait for 8K 120Hz? If you‘re itching for a new TV, should you wait for the 8K 120Hz promised land? Unless you must have the absolute best, 4K 120Hz TVs available today still offer outstanding performance. And realistically, native 8K content to take full advantage of these cutting-edge displays remains scarce. You‘ll need to weigh how long you typically keep TVs and when you foresee upgrading next. Rest assured, the electronics industry is moving full steam towards 8K 120Hz. But there are still hurdles to overcome in processors, panels, and the entire video distribution chain. While this ultra-high resolution holy grail may not arrive tomorrow, it‘s exciting to see how quickly capabilities are advancing. I hope this gives you a comprehensive look at where 8K 120Hz stands today. Let me know if you have any other questions! As someone who loves experiencing the best display technologies out there, I‘m happy to chat more about what the future holds. --- Source: [Do 8K 120Hz TVs exist?](https://33rdsquare.com/do-8k-120hz-tvs-exist/)
