Does FreeSync Work With HDMI?


If you are looking for a gaming laptop, personal laptop, or a monitor, you should know about the FreeSync technology and more about it.

Here is what FreeSync is, what difference it can make to the display quality, and more.

What is FreeSync?

FreeSync is a technology found on monitors, laptops, and TV screens. It is a variable refresh rate, i.e., the rate at which pictures on the display monitor are refreshed and synchronized with the graphics card’s frame rate.

Freesync (explanation and demonstration)

The monitor and graphics card communicate with each other to create an image. Sometimes, the lagging between the graphics card frame rate and the monitor’s refresh rate allows pictures to avoid picture tearing. Further, it also prevents input lag. Input lag occurs when the refresh occurs faster than the frame rate now. This will cause screen stuttering, i.e., you will see various images one over the other.

To prevent both situations from arising, FreeSync works in perfect sync and allows the GPU and refresh rate of the monitor to work in perfect harmony.

Traditionally, displays and monitors used to work on G-SYNC, which is the same technology as FreeSync. G-Sync is by NVIDIA, whereas FreeSync technology is by AMD.

Does FreeSync work with HDMI?

Monitors with G-SYNC support variable refresh rates when connected to GPU via a DisplayPort input cable. Whereas, FreeSync can work with HDMI cable, DisplayPort, and USB-C. However, for FreeSync to work with USB-C, your monitor should also support DisplayPort Alternate Port. A display with no DisplayPort Alternate Port would not display images with FreeSync with a USB-C port.

AMD FreeSync working over HDMI

FreeSync by AMD comes in various versions. The basic FreeSync provides tear-free, low latency, and low flicker on monitors, whereas FreeSync Premium and FreeSync Premium Pro offer additional features. The basic tier does not support LFC. The Premium tier supports LFC and a refresh rate of 120Hz. Any monitor with VRR 2:1, i.e., 60Hz – 120Hz, would have FreeSync Premium.

In FreeSync Premium Pro, it gets all advantages of Premium + HDR support + better brightness and display quality.

What is LFC?

FreeSync is known to have a narrow dynamic refresh rate range, i.e., instead of 30-75Hz, it has 40 -75Hz or 48- 75Hz refresh rate. Due to this, if the frames per second drop-down way below the range, FreeSync stops working. For this, FreeSync uses AMD LFC technology, i.e., low frame rate compensation. To avoid the problem, this technology multiplies the refresh rate when the FPS drops below the lower range.

When looking for a monitor, look for a variable refresh rate range of ratio 2:1 i.e., 50Hz- 100Hz, and also LFC support.

Q&A

Is FreeSync only for DisplayPort?

FreeSync is supported on both HDMI and DisplayPort, so you don’t really have to worry about it. G-SYNC, NVIDIA’s VRR technology, is only supported over DisplayPort at the moment, so if you have an NVIDIA graphics card, a DisplayPort connection is best.

How do I turn on FreeSync HDMI?

How to Enable G-Sync on FreeSync Monitors (Nvidia GPU on Radeon …

Do you need HDMI 2.1 for FreeSync?

The Series S and Series X support HDMI 2.1, and feature more advanced levels of AMD FreeSync with refresh rates up to 120Hz. FreeSync on Xbox consoles does need to be enabled in the dashboard settings as it does not automatically switch on even when connected to a compatible FreeSync display.

Is FreeSync good for gaming?

If you find a monitor that matches what you want in these respects, whether the monitor is G-Sync, G-Sync Compatible, or FreeSync shouldn’t matter too much providing your graphics card is compatible – all will provide high quality, the tear-free gaming experience with minimal input delay once configured properly.

Does FreeSync lower FPS?

As long as you are within the dynamic refresh rate range of FreeSync, you will not experience screen stuttering, tearing, or a noticeable increase in input lag. If your FPS (Frames Per Second) dips below that range, though, FreeSync stops working.

Does HDMI 1.4 support FreeSync?

Yes, FreeSync technology has supported HDMI since its inception. Many FreeSync certified displays have supported variable refresh rate technologies over HDMI since long before HDMI 2.1 was released and HDMI VRR was adopted.

Why is AMD FreeSync not supported?

First you should check if it’s a hardware issue by changing to another port. For example, if you’re using HDMI, try DP instead and see how it goes. Note that you’ll need an HDMI 2.0 or DP 1.2 cable for FreeSync to work properly. If the other ports work perfectly, you might be looking at a faulty GPU/cable/monitor.

Is FreeSync better than 144hz?

With FreeSync at 60 Hz, you’d be limited to 60 FPS at 60 Hz. That’s not bad, but it’s not great. With a 144 Hz capable FreeSync monitor, your framerate would be unlimited, and your refresh rate would be much higher as well due to the synchronizing of the refresh rate to frame rate.

Is FreeSync for GPU or CPU?

FreeSync is AMD’s take on Adaptive-Sync, similar to Nvidia’s G-Sync. Just like you need an AMD GPU to use FreeSync, you need an Nvidia GPU (it could also be third-party branded) to use G-Sync. One key difference is that in addition to DisplayPort, (which also works over USB-C), FreeSync works with HDMI.

Should I turn FreeSync on PS5?

Plus, with HDMI 2.1 VRR likely heading our way for the PS5, FreeSync is not a necessary technology. For those that wish to experience games at 120Hz with VRR enabled in the future, we’d recommend getting a standout HDMI 2.1 monitor to match your PS5.

Does FreeSync stop screen tearing?

What Is FreeSync And What Does It Do? So, if you’re getting 65FPS on a 144Hz gaming monitor that supports VRR with a 48-144Hz range, the monitor will dynamically change its refresh rate to 65Hz thus eliminating screen tearing and stuttering at imperceptible input lag penalty (~1ms)!

Should you always enable FreeSync?

Since AMD FreeSync is based on VESA’s Adaptive-Sync technology which is a free and open standard, it doesn’t increase the monitor’s price. FreeSync can completely eliminate screen tearing and stuttering by providing you with a variable refresh rate if you have a compatible graphics card, so it’s definitely worth it.

Do I need FreeSync for 60Hz?

If it’s a 60Hz display, then it only supports 60 frames per second. If the GPU’s output drops, the display’s refresh rate drops accordingly. If you’re playing a relatively simple PC game like the original Half-Life, you probably don’t even need FreeSync.

How do I enable G-Sync on my FreeSync monitor with HDMI?

How do I use G-Sync on a FreeSync monitor?

  1. Open Nvidia Control Panel.
  2. Got to “Display: Set up G-SYNC”
  3. Check “Enable G-SYNC G-SYNC Compatible” and select your preferred options.
  4. Select your monitor.
  5. Check “Enable settings for the selected display model”
  6. Apply settings.

How do I connect my FreeSync monitor?

Enabling AMD FreeSync in Radeon Settings

  1. Open Radeon Settings. This can be done in any of the following ways: Right-click on your desktop and select AMD Radeon Settings.
  2. Select Display.
  3. Confirm that AMD FreeSync is On. AMD FreeSync can also be turned off from this menu.
  4. Once changes have been made, close Radeon Settings.

Why is AMD FreeSync not supported?

First you should check if it’s a hardware issue by changing to another port. For example, if you’re using HDMI, try DP instead and see how it goes. Note that you’ll need a HDMI 2.0 or DP 1.2 cable for FreeSync to work properly. If the other ports work perfectly, you might be looking at a faulty GPU/cable/monitor.

Conclusion

FreeSync has thus, worked with HDMI since it was launched. FreeSync was known for supporting variable refresh rates over HDMI way before HDMI 2.1, or HDMI VRR.

Buying a FreeSync certified display/monitor will freely support HDMI and Variable refresh rates even if your monitor does not support HDMI 2.1.

Over 50 TVs in the market support AMD FreeSync and over 950 monitors that support FreeSync.
