As someone who spends a lot of time in front of a computer screen, I know how important it is to have a display that provides crystal-clear visuals and smooth performance.
I decided to investigate two popular display technologies – G-Sync and ULMB – to see which comes out on top.
G-Sync and ULMB are designed to improve your gaming and visual experiences but function differently. Understanding the differences and knowing when to use one over the other can be key to getting the most out of your display.
In this article, I’ll explain G-Sync and ULMB and help you decide which is right.
Let’s dive in!
What is G-Sync?
G-Sync is a proprietary technology developed by NVIDIA, the graphics card manufacturer. Its primary function is to reduce screen tearing and input lag while gaming.
If you’re unfamiliar with these terms, screen tearing occurs when there is a mismatch between the frames rendered by the graphics card and the monitor’s refresh rate. This results in a visual artifact where the top and bottom halves of the screen appear to be split.
Input lag is the delay between inputting a command and the time it’s reflected on the screen.
G-Sync technology synchronizes the monitor’s refresh rate to the graphics card output. This means that whenever the graphics card presents a new frame for display, the monitor will refresh its screen. The result is a seamless and smooth display with no tearing or lag.
But how does G-Sync achieve this synchronization?
Well, the answer lies in a piece of hardware called the G-Sync module, built into certain monitors that are compatible with this technology. The G-Sync module communicates with the graphics card in real time to determine the monitor’s best refresh rate at any moment.
This is achieved by adjusting the refresh rate dynamically, ranging from as low as 30Hz to as high as 240Hz, depending on the game and the graphics card’s performance.
You may be wondering what hardware you need to use G Sync. First and foremost, you’ll need an NVIDIA graphics card that supports G-Sync. This includes most of the company’s modern graphics cards, ranging from the GeForce GTX 10 series to the latest GeForce RTX 30 series.
In addition, you’ll need a gaming monitor with a G-Sync module built-in. However, not all monitors that support G-Sync are built with this module. Some cheaper monitors may only have a software implementation of G-Sync called G-Sync Compatible, which may not provide the same level of performance as a monitor with a G-Sync module.
Pros and Cons of G-Sync
On the positive side, this technology provides a significant improvement in the way games look and feel. With G-Sync enabled in games that support it, you’ll notice smoother animations, faster response times, and a much more immersive gaming experience.
However, there are a couple of drawbacks. First, G-Sync monitors tend to be more expensive than their non-G-Sync counterparts. Additionally, using G-Sync can impact FPS performance, which may concern competitive gamers who prioritize high frame rates over all else.
What is ULMB?
ULMB, which stands for Ultra Low Motion Blur, is a technology that reduces motion blur on a monitor. Motion blur occurs when there is significant movement on the screen, such as when playing fast-paced games, making it difficult to see objects.
With ULMB, this blur is minimized, resulting in a much clearer and crisper display.
But how does ULMB achieve this?
Well, it works by strobing the monitor’s backlight when the frame is being refreshed, essentially turning the monitor off briefly while the frame is being switched.
This strobing is synchronized with the monitor’s refresh rate and can be adjusted to match the game’s frame rate. The result is a much clearer and crisper image with minimal motion blur.
One thing to note is that not all monitors are compatible with ULMB. This technology is only available on select monitors, requiring certain specifications to work properly.
To use ULMB, you’ll need a monitor with a high-speed refresh rate of at least 100Hz, and support for DisplayPort or HDMI. Not all games are compatible with ULMB, so it’s important to check whether the games you want to play support it.
Pros and Cons of ULMB
This technology is particularly useful for gamers who play fast-paced games. It can significantly reduce motion blur and make seeing objects moving quickly on the screen easier. Additionally, ULMB can provide a more immersive gaming experience with a clearer and more detailed display.
However, there are some drawbacks to consider as well. First and foremost, ULMB can cause a significant drop in brightness, which may concern some users. Additionally, using ULMB can cause flickering, which some users may find distracting or even headache-inducing.
G-Sync vs ULMB Comparison Table
| Criteria | G-Sync | ULMB |
|---|---|---|
| FPS impact | May have slight impact | No impact |
| Input lag | Minimized | No impact |
| Screen tearing | Minimized | Can be minimized, not as effective as G-Sync |
| Motion blur | Can be minimized, not as effective as ULMB | Minimized |
| Brightness | No negative impact | Significant drop in brightness |
| Cost | Expensive | Monitors with high refresh rate are required, some monitors provide this as an extra |
| Compatibility | NVIDIA graphics card required | Compatible with a wider range of monitors, requires high refresh rate |
G-Sync vs ULMB: Which One Should You Choose?
Performance and Quality
In terms of performance and quality, both G-Sync and ULMB are designed to provide a smoother and clearer display. However, they achieve this goal in different ways.
G-Sync is designed to reduce screen tearing and input lag during gameplay. This technology synchronizes the monitor’s refresh rate with the graphics card output, resulting in a smoother and more seamless experience.
This means the animations and movement will appear much smoother, and you will experience less lag during fast-paced action moments.
On the other hand, ULMB is designed to reduce motion blur on the screen. This means fast-moving objects will appear much clearer and crisper, with minimal blur. With ULMB, you’ll see objects on the screen more clearly and quickly, which can be especially useful for first-person shooter games.
Compatibility and Cost
When it comes to compatibility and cost, G-Sync and ULMB differ significantly.
G-Sync requires that you own an NVIDIA graphics card compatible with this technology. In addition, you’ll need a monitor with a G-Sync module built-in, which tends to be pricier than non-G-Sync monitors.
However, a software-based implementation of G-Sync called G-Sync Compatible offers compatibility with a wider range of monitors.
ULMB, on the other hand, is compatible with a wider range of monitors with a high-speed refresh rate of at least 100Hz. However, not all games are compatible with ULMB, so it’s important to check whether the games you play to support this technology.
G-Sync vs ULMB: Which One is Better for Gaming?
When it comes down to it, the answer to this question will depend on your personal preferences and gaming style. If you love fast-paced games with a lot of action, ULMB may be your better choice. This technology reduces motion blur on the screen, making it easier to see fast-moving objects.
On the other hand, if you value a smooth and seamless experience during gameplay, G-Sync may be the better choice for you. This technology synchronizes the refresh rate of your monitor with the output of your graphics card, reducing screen tearing and input lag during gameplay.
G-Sync vs ULMB: Which One is Better for Gaming?
Let’s take a closer look at each technology based on these criteria:
- FPS: G-Sync may have a slight impact on FPS performance. Some games may run slower with G-Sync enabled. ULMB has no impact on FPS.
- Input lag: G-Sync can minimize input lag. ULMB has no impact on input lag.
- Screen tearing: G-Sync is specifically designed to minimize screen tearing. ULMB can also help minimize it but is not as effective as G-Sync.
- Motion blur: ULMB is specifically designed to minimize motion blur. G-Sync can also help minimize it, but it is less effective than ULMB.
- Brightness: Enabling ULMB can cause a significant drop in brightness. G-Sync has no negative impact on brightness.
Based on these factors, choosing between the two technologies will ultimately depend on what is most important for you as a gamer.
If you prioritize smoothness and want to minimize screen tearing and input lag, G-Sync may be your better choice. However, keep in mind that enabling G-Sync can have an impact on FPS performance.
If you prioritize clarity and want to minimize motion blur, ULMB may be your better choice. However, remember that enabling ULMB can cause a significant drop in brightness.
