Understanding G-Sync and FreeSync on Your LG 27GS75Q
First, a quick refresher. Both G-Sync (from NVIDIA) and FreeSync (from AMD) are types of "adaptive sync" technology. Their job is to synchronise your monitor's refresh rate with the frames-per-second (FPS) your graphics card is pushing out. The result? Buttery-smooth gameplay, free from that horrible screen tearing and stutter that can ruin a critical moment.
The LG 27GS75Q is what's known as "G-Sync Compatible." This means it doesn't have NVIDIA's dedicated hardware chip inside, but it has been tested and certified by NVIDIA to deliver a solid G-Sync experience. It also fully supports AMD's open-standard FreeSync Premium. This dual-compatibility is a massive win, making it one of the most versatile LG monitors in South Africa.
So, which one do you pick? The answer is beautifully simple: it depends entirely on your graphics card.
Choosing the Best Mode for Your Gaming Rig 🚀
The best mode for gaming on the LG 27GS75Q isn't about which technology is superior in a vacuum; it's about matching the monitor's features to your PC's hardware. Let's break it down.
For Team Green: NVIDIA GeForce Graphics Cards
If your rig is powered by an NVIDIA GeForce card (like an RTX 3060, RTX 4070, etc.), your choice is clear: G-Sync is the way to go.
- Connect via DisplayPort: This is crucial. G-Sync Compatibility on this monitor works over a DisplayPort connection, not HDMI.
- Enable in Monitor OSD: First, open your monitor's on-screen display (OSD) using the joystick underneath. Navigate to the Game Adjust settings and ensure Adaptive-Sync is turned ON.
- Activate in NVIDIA Control Panel: Right-click your desktop, open the NVIDIA Control Panel, and go to "Set up G-SYNC." Tick the "Enable G-SYNC, G-SYNC Compatible" box. Select your LG 27GS75Q, and be sure to tick the box for "Enable settings for the selected display model."
That's it! Your monitor and GPU will now be in perfect harmony.

Driver Check Pro Tip 🔧
Always make sure you have the latest GeForce Game Ready Driver installed. NVIDIA frequently updates its drivers to improve performance and compatibility with monitors like the LG 27GS75Q. A quick check before a gaming session can save you a lot of headaches.
For Team Red: AMD Radeon Graphics Cards
Rocking an AMD Radeon card (like an RX 6700 XT or RX 7800 XT)? You'll be using FreeSync Premium, which this monitor supports natively.
- Connect via DisplayPort or HDMI: FreeSync is a bit more flexible and generally works over modern HDMI connections as well as DisplayPort, but we still recommend DisplayPort for the highest refresh rates.
- Enable in Monitor OSD: Just like with G-Sync, ensure Adaptive-Sync is turned ON in the monitor's own settings menu.
- Activate in AMD Software: Open the AMD Software: Adrenalin Edition app. Go to the "Gaming" tab, then "Display." From here, you can toggle AMD FreeSync Premium to "On."
You're all set for tear-free gaming on your AMD-powered machine.
So, What's the Real-World Difference?
Honestly, for the end-user, the experience between a properly configured LG 27GS75Q running in G-Sync Compatible mode vs FreeSync Premium mode is virtually identical. ✨ Both eliminate tearing and reduce stutter, making fast-paced games like Apex Legends, Warzone, or Valorant feel incredibly responsive and smooth. The key is simply choosing the mode that matches your hardware.

While this LG monitor offers fantastic flexibility, the world of PC monitors is vast. Some gamers might prefer displays with native G-Sync (NVIDIA) hardware for the ultimate assurance, while others stick to the wide variety of FreeSync (AMD) screens. You can even find general Adaptive Sync models or, for esports purists on a budget, high-refresh-rate panels with None of these features to maximise raw speed.

Yes. The LG 27GS75Q supports G-Sync Compatible mode with compatible NVIDIA GPUs — check 'lg 27gs75q gsync compatibility' for GPU lists and driver versions.
Yes. The monitor natively supports AMD FreeSync for tear-free variable refresh rate at up to 165Hz when paired with FreeSync-capable GPUs.
Both can deliver low input lag when configured correctly; G-Sync Compatible often feels marginally smoother with NVIDIA GPUs at variable refresh rates.
Use DisplayPort for full VRR range and 165Hz. Some HDMI ports support VRR, but DisplayPort ensures best 'variable refresh rate' performance.
Enable the GPU-native sync (G-Sync on NVIDIA, FreeSync on AMD) and cap FPS near 165 for consistent frame pacing and minimal stutter.
Enable Adaptive Sync in monitor OSD, turn on G-Sync or FreeSync in your GPU control panel, set refresh to 165Hz and use a DisplayPort cable.
HDR can affect VRR behavior on some GPUs. Test HDR with 'lg 27gs75q freesync compatibility' and update drivers if VRR toggles unexpectedly.
