Explaining OLED screens and Dark Mode

Why that screen fits in the dark

Published

on

Most of the applications you’re currently using must have rolled out their own version of dark mode by now. The smooth transition from a light to dark interface can be done through a push of a button, or by sending the moon emoji on Messenger. A lot of people also find dark mode quite sexy, and that’s probably because of the screen they’re looking at.

A lot of newly released smartphones now have OLED screens, and dark mode seems to work best on such displays! But why is that? How do OLED panels allow dark mode to flourish?

Better, blacker, affordable screens

Organic LED (light-emitting diode) or OLED is essentially a kind of display technology. In a nutshell, OLED panels allow for better and clearer images and colors.

Thin layers of carbon fiber make up OLED screens. Because of these lightweight fibers, screens show brighter and more vibrant colors. Apart from that, OLED screens show deeper blacks and reduce instances of motion blur when navigating. The best part is that OLED screens are becoming gradually cheaper to manufacture. That explains why more and more of today’s smartphones use this panel.

More colorful than the rest

In comparison to regular LED screens of the past, OLED promises more accurate colors by producing light from individual pixels, instead of relying on backlighting. Back then, LCD screens relied heavily on the backlight of the display to make colors pop. Although, such displays also make the colors seem washed, especially when compared to OLED.

However, OLED’s colors don’t always turn out better than on LED and LCD screens. One such case is when you turn your screen’s brightness to its maximum, especially under strong daylight conditions. LED and LCD screens are designed to perform relatively better in color accuracy when your screen’s brightness is set to max. OLED screens were not designed for maximum brightness, so colors at that point would be saturated.

Which OLED is best?

There are two types of OLED technologies that currently exist: AMOLED and PMOLED. A lot of people hear AMOLED tossed around a lot because lots of smartphones use it. Essentially, AMOLED uses a storage capacitor that controls how much light each individual pixel will give off. It’s the one responsible for projecting all sorts of vibrant colors on most OLED smartphone screens. Apart from that, AMOLED screens do support wider resolutions at a more affordable and efficient rate.

PMOLED, on the other hand, does not have a storage capacitor and instead relies on user control. Essentially, the user will control lighting settings, and the individual pixels will adjust accordingly. You can find PMOLED screens on smaller devices like older iPods and pocket Wi-Fi devices. Take note that these screens use more power to implement such color changes.

Joining the dark side

Ever since dark mode rolled out for different apps and interfaces, people have been contemplating on switching to it — and for good reason. On normal LED or LCD screens, the new feature does not bode well with the technology. The depth of the black their dark mode possesses is not reflected well, to the point that the blacks look more gray than actual black. This is much more obvious when the screen’s brightness is turned all the way up.

Aesthetically, dark mode looks better on OLED screens because of the technology’s emphasis on deeper blacks. Most OLED screens have capacitors that control light passing through each pixel, which also works for blacks and whites. As such, dark mode shows up deeper and blacker, which is the intended look compared to regular modes. But, there’s actually more to just aesthetics for this mode.

It’s also been proven that dark mode on OLED helps save your battery life. Google confirmed this at its Android Dev Summit, citing that on max brightness, blacks consume less power than all other colors. Individual pixels need less electricity to show blacks on screen, which results in lower power consumption through time. Note that Google got these findings through tests on their original Pixel smartphones and their own apps like YouTube.

What’s left for OLED and dark mode

Apps and operating systems are now starting to embrace or consider incorporating dark mode into their software. While apps like Twitter and YouTube introduced such an option early on, others are beginning to take notice. Of course, you’re gonna need the right screen to fully immerse yourself.

It has been proven: OLED and dark mode are indeed a perfect match. But, it is entirely up to you whether you want to stay in the light or switch to the dark side.

AMD launches Ryzen 5000 desktop processors with major generational improvements

Available on November 5

Published

on

AMD recently took the wraps off its Ryzen 5000 desktop processors. The new processors tout improvements across the board, from improved performance-per-watt to increased instructions-per-clock.

The processors are still using the same 7nm node used in the Ryzen 3000 CPUs. However, as compared to the previous CPUs, Ryzen 5000 boasts a new design that further reduces latency and gives cores more access to the L3 cache. Improvements in design also translate to 24% more performance-per-watt for the new Ryzen processors compared to its predecessor.

Gamers will really benefit from these improvements with AMD touting a 19% generational increase in instructions-per-clock on Ryzen 5000 processors. The company says that it is their largest increase yet since the introduction of Zen processors.

Now, there are no Ryzen 4000 desktop processors since AMD wants to streamline its processor offerings. Ryzen 4000 mobile processors — the one used on laptops — use Zen 2 architecture while Ryzen 5000 desktop processors use Zen 3. As such, the naming also signifies generational improvements across architecture and performance.

Headlining the Ryzen 5000 processors is the top-of-the-line Ryzen 9 5950X. It comes with 16 cores and 32 threads, having a base frequency of 3.4GHz, and a boost frequency of 4.9GHz. Meanwhile, its total cache is 72MB while its TDP is rated at 105W.

Then, there’s the rest of the lineup. AMD Ryzen 9 5900X has 12 cores, 24 threads, and a base frequency of 3.7GHz with a boost frequency of up to 4.8GHz. Its total cache is at 70MB, and its TDP maxes out at 105W. For this processor, the company touts 7% faster 1080P gaming than its closest competitor, Intel Core i9-10900K.

There’s also the AMD Ryzen 7 5800X which is an 8-core, 16-thread CPU with a base frequency of 3.8GHz and goes up to 4.7GHz. The TDP is the same with other higher-end processors, clocking in at 105W. Meanwhile, its total cache maxes out at 36MB.

Finally, there’s the Ryzen 5 5600X. It is a 6-core, 12-thread CPU with a base frequency of 3.7GHz and maxes out at 4.6GHz. The total cache is 35MB. Its TDP is significantly lower than the three,  coming in at 65W.

Pricing and availability

All Ryzen 5000 processors are will be available to order on November 5. The top-of-the-line Ryzen 9 5900X starts at US$ 799. Meanwhile, the Ryzen 9 5900X will retail at US$ 549. The Ryzen 7 5800X and Ryzen 5 5600X will come at a much affordable price of US$ 449 and US$ 249, respectively.

It’s worth noting that AMD will also launch the AMD Radeon RX 6000 GPUs sometime before the Ryzen 5000 processors hit the shelves. These GPUs are expected to use RDNA 2 GPU architecture, which is the one used for Xbox Series X and Sony Playstation 5. An October 28 announcement is already set in stone for the Radeon GPUs.

Samsung 27-inch Curved Gaming Monitor review: All you could ever want

A great gaming display thanks to high refresh rate and curved built.

Published

on

Samsung 27-inch Curved Gaming Monito

A lot of people find something nice about a curved display. I personally think that this kind of display gives you an illusion of depth to anything you put on it. Whether it’s playing a game or watching a video in full-screen mode, it gives you that sense of immersion. Of course, part of it also comes with bright and accurate coloring.

This is what I feel the Samsung 27-inch WQHD Curved Gaming Monitor offers, on paper. It’s a widescreen, curved display mostly suited for competitive gamers thanks to its high refresh rate. With multiple features suited for the competitive player, it’s the ideal monitor for people looking to build their first gaming setup.

But if you’re just looking for a great monitor for your home/office space, or if you’re just a casual gamer, should you even consider this? 

For starters, there’s the high refresh rate and it’s curved

The Samsung 27-inch Curved Gaming Monitor comes with a 144Hz refresh rate, a staple for most. Obviously with such a high refresh rate, you get some kind of increase in gaming performance. With this monitor, my experience was just along what you’d expect.

Every time I played a game on it, the whole experience just felt smooth. I’m not the most competitive gamer in the whole world, as long as I get to run the game. However, to me it still hits differently when you see the game run smoothly as you trudge along the battles.

Samsung 27-inch Curved Gaming Monito

As the name suggests, it’s also a curved display — and I felt this is the ideal way to construct a gaming monitor. Now, for most games I’ve played, having a curved display has its perks. With such a large amount of screen space that just curves along, I roughly get to see the whole game’s environment. In essence, you feel some semblance of immersion every time you play Fortnite or Call of Duty Warzone.

Port selection is pretty great for the most part

Along with the high refresh rate, the Samsung 27-inch Curved Gaming Monitor also has a nice selection of ports. It comes with two HDMI ports and a DisplayPort 1.2, all of which you can switch to on the fly. I feel like this is more of a standard across most gaming monitors, but Samsung does things differently with their ports.

From L to R: HDMI 1, HDMI 2, DisplayPort 1,2m Audio, Power

Apparently, only one HDMI port actually grants you the 144Hz refresh rate. Out of the two HDMI ports that come with the device, only the HDMI 2 port gives you the high refresh rate. I’m not entirely sure why Samsung decided to do this. I’ve heard that some of their other products also place the high refresh rate option on a specific port.

Furthermore, I would have loved for them to include a DisplayPort cable along with the HDMI cable. Given that most GPUs come with a DisplayPort anyway, I think this would have been a nice move. Also, the DisplayPort supports the 144Hz refresh rate so I felt this was a missed opportunity on their part.

Speaking of missed opportunities

Another missed opportunity for this monitor was giving it FreeSync or G-Sync support. I know that other similar models of the Samsung 27-inch Curved Gaming Monitor come with FreeSync support. However, the model I have didn’t — the DisplayPort doesn’t support it, and it honestly would have made the display perform better.

With FreeSync, you’re able to play your games at a stunning rate without losing much detail. In essence, it allows you to react faster — especially for most FPS games like Valorant and CS:GO. Obviously, FreeSync also raises some risks especially when you’re playing for longer hours. However, it would have provided this monitor with better performance if it supported it.

As a casual gamer, I honestly didn’t mind that FreeSync wasn’t supported mostly because I was still happily playing at 144Hz anyway. However, there were instances when I felt the game lag behind a bit. It would have been nice if the amount of lag I experienced was reduced, and FreeSync would’ve been a great thing to have.

Is this your GadgetMatch?

For PhP 27,199 (US$ 562), the Samsung 27-inch Curved Gaming Monitor is a pretty decent curved gaming display. It’s biggest selling point is in its high 144Hz refresh rate, which fits both competitive and casual gamers alike. Also, it being a curved display allows for greater immersion during gameplay.

Of course, this does have some missing technologies that would have made it better. I felt that this monitor had some missed opportunities that would have improved its performance in the long run. But, as a casual gamer, it honestly doesn’t matter to me as much as it would to others.

Overall, this gaming monitor serves its ideal purpose for those who need it. If you’re more casual than competitive, this is honestly all you could ever want.
