Earlier this year we put Nvidia's back up for FreeSync monitors to the test, grabbed every FreeSync monitor we had in the function, hooked them up to a collection of Nvidia GPUs, and verified that in all cases adaptive sync worked as expected.

LG saw that article and noticed we didn't test any LG monitors -- nosotros didn't have any on hand -- so they did their function and sent us five of their latest gaming monitors for a test drive to meet how well they behaved with Nvidia GPUs. Nosotros haven't formally reviewed whatsoever LG monitors in a long fourth dimension, and we idea we'd take the opportunity to revisit Nvidia's FreeSync back up with a collection of new, and in some cases, quite popular displays.

As a quick refresher, about two months agone Nvidia opened up to support the VESA Adaptive Sync standard (a.k.a. FreeSync) with their Pascal and newer graphics cards. All it took was a driver update, and voila!

Equally a side annotation, Nvidia's electric current GPU architectures have had the power to drive adaptive sync displays -- it's effectively how Grand-Sync works in laptops -- only for desktop cards it was locked downwards, so Nvidia could push their Chiliad-Sync monitor ecosystem.

Since the update, we now have a multi-tier monitor ecosystem for GeForce GPU owners. At the top we take the monitors that feature a custom G-Sync module, branded as either "Grand-Sync" or "K-Sync Ultimate" for HDR monitors. Below that we accept G-Sync Compatible; these are adaptive sync monitors Nvidia has certified to work properly with their GPUs. They accept virtually the same feature set as full Yard-Sync displays, and they volition accept adaptive sync enabled by default out of the box.

However, there's also an option in the Nvidia Command Panel to enable adaptive sync on any FreeSync monitor, regardless of whether it's been certified or not. So yous don't demand to go out of your fashion to buy a G-Sync Uniform monitor, considering whatsoever FreeSync display should piece of work fine, and that'due south what nosotros showed in our previous article and what many of you guys have been telling u.s.a. also.

This was a positive and almost generous move past Nvidia, or at the very to the lowest degree a welcomed shift in their strategy. Nvidia did accept the fourth dimension to discredit the FreeSync ecosystem for reportedly having issues like blanking or flickering, suggesting that their certification process was necessary to ensure you don't stop upwards with issues. Simply from what we've seen, 99% of uncertified monitors piece of work fine. In fact, those cited bug are non bug with FreeSync, rather they're monitor-specific issues that if you meet them, you lot should render the brandish.

The tests we performed were very straightforward. We plugged in all LG monitors to a test rig loaded upward with a GeForce RTX 2080 Ti, one at a time, of form. The next footstep was to enable FreeSync in the monitor's settings, all five displays came with FreeSync disabled out of the box, yous need to turn information technology on using the on-screen display for Nvidia to recognize it as an adaptive sync monitor.

Where possible we used the extended FreeSync style, which delivers the widest refresh rate range.

LG really notes this manner, which is almost a form of display overclocking, could cause flickering, only we'll hash out whether this was an issue when we become through each model.

After enabling FreeSync in the display's settings, we enabled adaptive sync in the Nvidia Control Panel and we were skilful to become. The five monitors were recognized equally supporting adaptive sync past the GPU afterwards FreeSync was enabled, so that was the commencement good sign.

One of Nvidia'south requirements for Yard-Sync Uniform certification is to take FreeSync enabled by default, so nosotros suspect that'due south one reason these LG monitors don't immediately pass certification. Bit of a nitpick requirement because it ways many FreeSync monitors neglect certification despite existence otherwise perfectly capable.

Going through each monitor individually, basically nosotros were checking whether there were any flickering issues, blanking, refresh rate inconsistencies, and so on, when adaptive sync was activated. In particular we were interested in seeing how the monitors behaved around potentially problematic points: below the minimum refresh rate and transitioning in and out of the refresh windows.

LG 32GK850F 32" QHD ($645)

The first monitor we tested was the LG 32GK850F, a 32-inch apartment VA panel with a 1440p resolution and 144 Hz maximum refresh rate. This is likewise a FreeSync 2 certified brandish, supporting HDR with DisplayHDR 400 certification. This monitor has a fifty to 144 Hz refresh window, so it supports a crucial feature called low framerate compensation (or LFC), which extends the adaptive sync window down to one Hz, allowing the monitor to have no minimum refresh.

You lot'll only get a good FreeSync experience with monitors that support LFC, so we're glad to report LFC works fine with this monitor and Nvidia GPUs as expected.

We encountered no problems with this brandish. The transition within and out of the refresh window, around the 45 to 55 Hz range, was handled perfectly without flickering or artifacts. LFC is activated equally expected. And the monitor works with FreeSync whether you have HDR enabled or disabled, then turning on HDR has no impact on the adaptive sync experience. A great result and this is a monitor that I call up is neat quality in general with a top-notch VA panel, plus we beloved that it's flat.

LG Ultragear 24GL600F-B 24" ($280)

The 24GL600F is a more basic gaming monitor, featuring a 24-inch 1080p 144Hz TN panel. It's designed to slot into that upkeep loftier-refresh category. No issues with this monitor, it too supports LFC, and we saw no issues transitioning in and out of the refresh window.

The merely small concern is that the monitor doesn't come with a DisplayPort cablevision in the box. Non a big bargain since a DisplayPort cable costs all of $10, merely if you were to employ the included HDMI cable (perhaps a less tech-inclined gamer) you will not get FreeSync support as Nvidia GPUs practise not support FreeSync over HDMI. Over DisplayPort, as expected there are no issues.

LG 27GK750F-B 27" FHD ($348)

Next up we have the 27GK750F, a rare 27-inch 1080p 240 Hz TN display. Normally y'all only see this refresh rate at 24 inches in size. A decent unit this one, especially if yous desire that super high refresh rate; when gaming this monitor feels really fast and some of that is down to lightning quick response times.

This isn't a review of the display, but we can report it works perfectly with adaptive sync on an Nvidia GPU.

Again, it supports LFC with a 48 to 240 Hz refresh window and across the unabridged refresh range, everything is handled well, no flickering or anything like that.

LG 32GK650F-B 32" QHD ($397)

The fourth display is the 32GK650F which is basically the same monitor as the 32GK850F just without HDR back up and a lower cost tag to match. It remains a 32-inch 1440p 144Hz VA, with a 50 to 144 Hz refresh window.

You guessed it too, we observed no problems with this brandish and with this combination of specs you're getting a great gaming experience if you take a decent enough GPU to drive it.

Certainly with the RTX 2080 Ti playing games on ultra settings higher up 100 FPS at 1440p was a boom.

LG 34GK950F-B 34" 21:9 WQHD ($1,188)

The last display we tested is the ultrawide 34GK950F, a 34-inch IPS monitor with a 3440 x 1440 resolution, 144 Hz maximum refresh rate and HDR back up. It's some other of LG monitors that supports FreeSync 2, although this isn't a feature you lot can use with Nvidia GPUs. You can still employ adaptive sync and HDR at the same fourth dimension, you just tin't enable FreeSync 2 in games that back up it like Assassin's Creed Odyssey, equally the feature is exclusive to AMD GPUs.

Support for LFC is present thanks to a 60 to 144 Hz refresh range and we didn't experience whatsoever flickering or blanking problems beneath or above the minimum refresh. We also wanted to specifically check the maximum refresh because 144 Hz is a step above the 120 and 100 Hz monitors nosotros've been seeing with similar specs lately, but even right up at 144 Hz there were no issues using the extended FreeSync style.

Closing Notes

Every bit expected, all 5 monitors piece of work perfectly with an Nvidia GPU to provide a fluid adaptive sync experience. All are loftier refresh models that support LFC, so the feel is as good as it should be with no abrupt transition between FreeSync on and off as your frame rate drops. Information technology's overall a really smooth experience on all of these displays.

LG was one of the first manufacturers to jump aboard the adaptive sync train and in 2022 their range has grown significantly to encompass lots of different models. Even their new TVs this year support FreeSync over HDMI for AMD GPU owners.

As we said in the original commodity, we think it's safe to say if yous buy a new FreeSync model today that it volition work fine with Nvidia GPUs. You shouldn't expect to come across any graphical bug, whether you purchase an LG monitor or a brandish from a different maker. Only the very early, older FreeSync monitors may have some problems.

Thus our recommendation continues to be to select your next monitor on its merits, features and preference. If information technology'south a FreeSync gaming monitor and you can save some money, that's bang-up. GeForce GPU owners no longer you demand to carp with G-Sync for getting proper variable refresh rate, unless that's the monitor yous desire for other factors as mentioned in a higher place. These results from a option of LG monitors simply reinforces that FreeSync gaming displays tin can and will perform perfectly.
