What Is a Gamecube Upscaler ?
Upscale is the process of converting one resolution to a higher level. When playing a Full-HD (1080p) movie or watching HD cable TV on a 4K TV , the TV must first upscale the resolution of the movie from 2 million pixels (1920 x 1080 pixels) to 8 million. pixels (3840 x 2160 pixels) to display on a 4K TV screen, also known as Ultra HD (UHD).
Upscaling is the process of increasing resolution or increasing sampling frequency for image, audio and video files to use them on devices with higher playback and display capabilities. For example, we can ‘upscale’ FullHD movies for the best viewing on a screen with 4K resolution – four times higher pixels than FullHD.
But for a long time, this technology has had a bad reputation because not only did not deliver the desired results, it could also reduce the quality of the content.
There is a very good saying about upscaling technology, which is “Put garbage in one end, then the other end will be trash”. If the actual input content (images, audio, video) is too poor, even being processed and displayed in high-end devices could not be better.
With still images and video (movies), upscaling means the device will have to generate new pixels, which can be considered ‘fake pixels’ to increase the resolution. This process is never perfect, and often leaves certain display errors. So when watching movies, people often choose the right resolution for their TV or monitor to avoid going through the upscaling process.
A simple example like the upscaling process of the Xbox One console, has been complained by many people for making the image quality of the game worse, losing detail, not being an upgrade anymore.
Resolution conversion of a movie increases the resolution through interpolation, by judging the creation of new pixels based on the surrounding pixels. Each pixel in a movie in Full-HD 1080p quality through the transition (upscale) becomes four pixels on the 4K TV screen. Typically, these 4 pixels are just duplicates of the original pixel or have little difference due to its limited interpolation. Sony alone includes a library of native 4K comparison images. Accordingly, the 4 additional pixels do not go through a simple calculation, but have to go through the direct comparison process with the standard 4K library to add new image information, making the image more detailed when viewed on the screen. 4K TV screen.
Upscale is not a new concept. This is the process of converting one resolution to a higher level. When playing a Full-HD (1080p) movie or watching HD cable TV on a 4K TV, the TV must first upscale the movie resolution from its original 2 million pixels (1920 x 1080 pixels) to 8 million pixels (3840 x 2160 pixels) to display on a 4K TV screen, also known as Ultra HD (UHD).
In the past, traditional TV companies often chose to convert the resolution of a movie to increase the resolution through linear interpolation, which means using the judgment of creating new pixels based on pulse pixels. around. For example, it is easy to understand like this: if the machine detects four objects around another object that are all chickens, then there is a very high chance that the object in the middle is also a chicken.
By this speculation, each pixel in a Full-HD 1080p movie becomes four pixels on a 4K TV screen. Usually, these 4 pixels are just duplicates of the original pixel or have little difference due to the old technology interpolation. Therefore, not the newly created pixel is always accurate (between 4 chickens can completely be 1 cat, for example).
So upscale with more modern technology will solve the problem of creating new wrong pixels? The answer is thanks to artificial intelligence.

New Points In Upscaling Technology
If your card is really struggling at 1080p, the 83% resolution scaling at 1080p will turn to 1600 x 900. Keep in mind this 83% is not a fixed number. You can increase this number for sharper images and lower performance – lower the number of FPS or lower the number for smoother gameplay, but the picture will also be blurred.
Both Nvidia and AMD provide resolution scaling options in their respective consoles. But for this article, we will be using the CRU (translate: Custom Resolution Utility) that can run on both platforms. We have found that resolution scaling in CRU has less compatibility issues and reliably renders in all games, unlike their own resolution scaling options.
Current technology
And now by the end of 2020, the PlayStation 5 and Xbox Series X have once again increased their hardware basics. Modern titles like Assassin’s Creed: Valhalla and Cyberpunk 2077 make the most advanced systems also struggle to run well at 4K. And while the settings can make the game lighter, it’s also only a fraction of it.
There is another way to significantly increase performance: resolution scaling.
Resolution scaling is a great option if you are looking for a 10-15% increase in fps after setup. If you’re playing at a higher resolution like 4K and you combine resolution scaling with image sharpening, the results are usually very close to the native 4K resolution.
What resolution scaling should you use? This depends on your monitor’s native resolution. Resolution scaling 83% is usually a good balance between image quality and performance. If you scale to 4K that means the resolution that the graphics card will have to render should be only 3200 x1800. If you scale to 2K, then the card will only need to render 2133 x 1200. At 1080p, the pixel density on most monitors is already pretty low, so we’ll avoid scaling if possible.
Resolution Scaling – the secret to playing 2K 4K games with weak cards
Like it or not, the beginning of a new console generation presents both challenges and opportunities for PC gamers. Shiny new-generation consoles feature relatively high-end hardware, which makes multi-platform games increase hardware requirements as well. You will find that, suddenly AAA games no longer run at the perfect 60 FPS on your GPU.
This has been going on for several generations. Back in 2005, early generation Xbox 360 games like F.E.A.R. and The Elder Scrolls IV: Oblivion, which struggled even with the top gaming PCs of the time. In 2014, Assassin’s Creed: Unity, arguably the first “real” game on Ubisoft’s next generation of consoles, made the flagship GeForce GTX 980 drag with 24 FPS at 1440p on PC. Multiplayer games on PS4 and Xbox One later released also made the PC need a higher configuration to run smoothly.
The Practical Effect Of Upscale
Upscale is not a theoretical technology, it brings a very real effect to 4K TV owners. Thanks to upscale, you will see the difference when viewing the same picture on a Full-HD TV (HDTV) compared to watching on a 4K TV with upscale technology. The sharpness, brightness, color, and contrast are all optimized by the 4K TV’s image processing chip, delivering better results. If you choose a 4K 55-inch or 65-inch TV, you can sit and watch at a distance of 1m – 1.5m to feel the difference.
Artificial Intelligence – The Solution To The Upscale Problem
Think of artificial intelligence as a child’s brain. We show that child a white-haired cat named A, he will not be able to tell that a black-haired cat named B is also in the feline family. But if we show that child the faces of 1,000 different cats, no matter what color the fur cat C has, the child knows that C is a cat. This is called the machine learning method of training. By giving a computer a lot of necessary information, it will be able to learn how to deduce, conclude exactly like a human.
That’s how Samsung engineers solve the upscale problem with the latest QLED 8K TVs. Using the most advanced machine learning processor, called Quantum Processor 8K, and supplied with millions of different photos and videos to “learn”, the TV can accurately recognize each pixel for execution. upscale correctly. Not using the method of guessing at the right time and the wrong time, when millions of examples all produce 1 result, the newly created pixel will be more accurate than ever. And from the normal image, we will have the image upscale to 8K resolution.
Thereby also to see how powerful the image processing chip on the latest 8K QLED TV is. When the problem is not to speculate a single pixel, we have more than 33 million pixels side by side, four times the number of pixels on any 4K TV currently on the market. Samsung’s 8K QLED TV can turn any image, from YouTube content, to DVD movies as sharp as 8K.
Samsung’s artificial intelligence upscale technology not only adds new pixels, but also changes lighting, color and contrast. This is something that older TVs using upscale with linear interpolation couldn’t do. By learning the actual scenarios available, Samsung’s 8K QLED TV can know when to increase brightness, when to soften colors. In particular, because artificial intelligence has the ability to constantly learn, Samsung also affirms that photos and videos are always updated to improve the TV’s upscale capabilities. Therefore, the longer you use it, the more beautiful, more detailed and realistic your home TV will be displayed.
The image uploaded on Samsung’s QLED 8K TV will always be sharper, clearer and more realistic. A very small detail, but proving that upscale with artificial intelligence is superior to traditional technology, it is that the writing on QLED 8K TV is always easier to read, making human eyes less tired.
The emergence of AI processing in upscaling
The weakest point of content upscaling is the pixel ‘guess’ process, which is done with simple algorithms and can be buggy. Therefore, Samsung equips its 8K TV lineup with a separate processor to do this task, and applies artificial intelligence for better quality than the old methods.
The artificial intelligence of these TVs will learn from the stock of available images provided by the company (constantly being updated over time), then ‘look’ at what users are taking on new pixels. smart content, not from low-quality input content.
For example, if there is an apple in the picture, the TV AI looks in the photo archive for pictures of the apple and then ‘compensates’ for the missing details due to the low resolution content source. .
Upscale Technology For More Vibrant Colors
There are a few different types of HDR on the market right now, but whatever it is, it’s better than not having one. The most important thing to keep in mind is that the HDR10 technology is completely free, and that almost every 4K TV today supports it. Dolby Vision, on the other hand, is likely to deliver better quality pictures, but manufacturers pay a fee to integrate the technology into their products, pushing the price of the TV higher.
In addition, the content you watch on TV must be designed to support Dolby Vision, otherwise you will spend large sums of money without taking advantage of its power. In general, if you have a tight budget but still want to experience 4K, Dolby Vision is probably not for you, but as long as your TV supports any other type of HDR, you can rest assured that Image quality has been improved.
Supports Local Dimming For Deeper Blacks
If you define “money doesn’t matter,” a TV with an OLED screen is just what you need. This type of screen lightens each pixel individually so the black will truly be black. In contrast, LCD TVs use LED backlighting that shines through a filter, so black is truly “the closest color possible to black”. Unless your TV supports local dimming.
Local dimming is a feature that allows the TV to change the uniformity of the LED backlight, increasing the contrast of the displayed image. For example, in the photo The Eye of Sauron above, the LEDs behind the eye will be brighter, while the LEDs behind the mountains in the dark will be darker. This will help the eyes to stand out, while the shadow areas become more subtle. Of course, this feature may not provide the same experience as the OLED display, but certainly the picture quality will be much better than TVs using uniformly bright panels.
Finding out how well a TV does upscale is difficult, as stores always display the best, best content, instead of the ones you’ll actually watch when you use them. Luckily, even if you buy a “non-standard” upscale product, you can still buy 4K Blu-ray players with superior upscale capabilities.
120hz Refresh Rate For Smooth Movements
Most of the content you watch, whether it’s movies or TV shows, is shot at around 30 frames per second. High quality video games are typically at 60 frames per second. So, what does a 120-frame-per-second TV do between those frames? Some TVs will try to “guess” what those intermediate frames will look like, also known as automatic motion smoothing, making the movement of the object unnatural. Other TVs will repeat frames, so if a movie is recorded at 30 frames per second, each frame will be displayed 4 times.
However, most movies today are shot at 24 frames per second. If you watch on a 60Hz TV, it won’t be able to loop the frame by the whole number of times, because 60 doesn’t divide by 24. To fix this, TV manufacturers use a technique called “3: 2 pulldown”. (pulldown term means simply dragging and dropping one frame so that it multiplies twice while the speed stays the same.3: 2 is the most common formula, multiplying the first frame by 3 times, and then multiplying the second frame. 2 times, and so on until the movie is over) but this technique produces a shaky effect and doesn’t feel smooth. 120Hz TVs don’t have this problem, as they repeat each frame 5 times (5 * 24 = 120). You might even hear many salespeople advertise that movement will get even smoother with a 240Hz TV, but unless you watch 3D content, you don’t really need it.
All in all, while 4K is a very valuable technology, it’s the aforementioned breakthroughs that make your entertainment experience full. Of course, a 4K TV with HDR, local dimming, standard upscale, and high refresh rate won’t be cheap, but you won’t want to save money if you decide to jump into the 4K game.
Upscale plays an extremely important role in the ability to display low-resolution content on 4K TVs
Before diving into our detailed review, we’ll learn some basics of the TV’s upscale feature as well as the X-Reality PRO chip that Sony is very proud of.
Upscale is a feature that dates back to the display industry’s earliest days, however it became popular only after the explosion of LCDs. Unlike previous CRT technology, LCD panels produce optimum picture quality solely at its native resolution.
So in order to bring the best viewing experience, manufacturers must integrate a special chip that does the upscale / downscale job, which converts the resolution of all sources to the original resolution of the screen. Figure. This is a very difficult task and many early HDTVs failed to convince viewers to show… cable TV, leading to many cases of half-laughter and quality.
On a technical level, upscale is the process by which the TV processor interpolates an image from a low-resolution source to the screen’s native resolution. For example, from FullHD (1920 x 1080) to 4K (3840 x 2160), the processor will have to interpolate from more than 2 million pixels to 8 million pixels, which is quadruple the original pixel count. This number will increase 8 times if the content plays in HD resolution (1280 x 720) or 24 times if the content is SD (720 x 480).
And of course, the most important part of evaluating the upscale feature of the 4K X-Reality PRO chip is its ability to present low-resolution content. For this case, HDvietnam chooses the movie The Hunger Game version with 720p resolution is quite popular. Of course, in practice, unless force majeure, you should choose 1080p (FullHD) is optimal to ensure image quality when upscale. However, this is a test, so HDvietnam chooses the lowest and most popular resolution is 720p (basically SD is the standard with the lowest resolution, but its popularity is not high) .
In general, if viewed at the ideal distance for a FullHD TV according to THX standards (from the viewing position to the TV with the diagonal of the mirrored screen), the displayed image quality is quite good (in this case, it is with Bravia 65X9000B). The details are interpolated very well and there are no annoying errors (also known as artifact due to incorrect analysis of the image, resulting in unnatural redundancy). Image breakage is completely non-existent, which is impressive considering the fact that the image on the screen is interpolated from a signal with up to eight times lower pixel count.
However, for 4K TV owners, because the resolution is 4 times higher than FullHD, they tend to sit closer than the THX standard for FullHD TVs. Specifically, for a 4K TV showing 4K content, you can sit at a distance of only the THX standard and still be able to ensure the sharpness of the image. Now, if compared to the original 4K signal, we will begin to see “breathless” images after upscale (HD), typically the detail of leaves, houses. However, overall is still very good. Unless you sit too close and are too difficult, this should not affect the experience.
However, for cases like in the Caesar Flickerman scene above, where the subject is human, the 4K X-Reality PRO upscale feature is quite impressive, even at close range. The sharpness of native 4K content cannot be claimed, but Sony’s imaging chip is a stellar finish in its capabilities. Pay attention to the face of Caesar’s character, we will easily see the details in both the bright and dark areas are very good. Noise is limited to a very low level and is difficult to discern under normal viewing conditions. Of course, it is necessary to reiterate that this is upscale content so if you are observant you will realize there is a certain “flat” in the image, because the additional details are due to the chip interpolating itself according to the details. around. As for the 720p source, it can be hard to ask for nothing more.
One plus point of Sony TV is that the color is in neutral default mode and does not push too high sharpness, which helps the image to be quite realistic, especially for upscale signals, without having to tweak much. . Some brands on the market today default to too high contrast and sharpness, which greatly affects the quality of upscale images, if not bad if you don’t edit them.
Frequently Asked Questions
Why should we use Upscale?
Content sources such as movies, video clips, cable TV, and satellite TV in true 4K quality are very rare in the market and on the internet. Analysts predict that in the next two years, 4K content will be richer and more popular, so upscale is still the current “savior” for online videos, or movies from scratch. Blu-ray discs, mobile devices.
Most famous television manufacturers now develop their own image conversion processing technologies that increase picture quality, sharpness, contrast, and more realistic expression. There are new 4K TVs from big-name manufacturers equipped with powerful upscale technology, bringing real effects to consumers. Japanese television maker Sony is one of the pioneering representatives in this field. The high-end 4K TVs available on the market from Sony such as BRAVIA X9500B, X9000B, S9000B and X8500B all feature 4K X-Reality PRO technology developed by Sony itself, providing visual experiences that you can hardly resist. again.
4K X-Reality PRO supports any source, so whether you’re watching movies from the Internet, or a Blu-ray player, or watching HD (720p) to Full-HD (1080p) video clips from the electricity smartphone (smartphone) or cable TV, the image resolution will be converted to near the 4K equivalent level. Image quality after being upscale will be minimized noise and video cleaning, accurate color correction, deep filtered images, help clarity but still retain authenticity. As a result, movies or videos in HD (720p) and Full-HD (1080p) quality often viewed well on HDTVs will display better on the big screen of 4K TV.
