At 60Hz, a display draws a new frame roughly every 16.7 milliseconds (1,000 ÷ 60). At 120Hz that wait drops to about 8.3 milliseconds (1,000 ÷ 120), and when a fast game renders enough frames to match, the difference shows in camera swings and in a crosshair following a target across the screen.
Three RayNeo AR display glasses refresh at up to 120Hz on a 1920×1080 Micro-OLED panel: RayNeo GT Max and RayNeo GT, which run at 120Hz in 2D, and RayNeo Air 4 Pro. GT Max is the one built around immersion, with a 59° field of view and a choice of three IPD sizes. GT trades some of that width for a lighter 68g frame and a higher pixel density, and Air 4 Pro is the entry-level model in RayNeo's AR entertainment range. A 120Hz picture also depends on the game and the device feeding it.
The shorter refresh interval gives the display twice as many chances per second to show a new image. When the game renders fast enough to fill those refreshes, camera pans and moving targets are drawn in more intermediate positions, which reads as smoother motion.
It can also shorten the wait between an action and its result on screen, because each refresh comes around sooner. How much of that a player notices depends on the game's actual frame rate and the rest of the system, so high-frame-rate shooters, racing games and fighting games are the natural fit. For slower strategy and turn-based games, the bigger screen sizes come into their own.
Three links in the 120Hz chain
Frame rate and refresh rate are separate numbers, and a full 120Hz experience needs both:
- The game renders the frames. To show 120 distinct images per second, it has to reach around 120fps, through a performance or 120fps mode on console or an uncapped or raised frame limit on PC. A game running at 60fps still displays on a 120Hz signal, just without the extra in-between frames.
- The source sends the signal. The PC, handheld or console outputs 120Hz to the glasses. Over USB-C that means a port with video output (DisplayPort Alt Mode or compatible Thunderbolt video). For HDMI sources, the RayNeo HDMI Adapter, sold separately, supports 1080p at 120Hz output alongside 4K@30Hz and 2K@30Hz.
- The glasses display it. GT Max and GT accept 120Hz in 2D over the DP-compatible USB-C cable in the box, and Air 4 Pro takes up to 120Hz through a direct DisplayPort-compatible USB-C connection.
Reaching 120Hz from a PC, a handheld or a console
On gaming PCs and laptops, a USB-C port with DisplayPort Alt Mode or Thunderbolt video output connects straight to the glasses over USB-C (GT and GT Max use the DP-compatible cable in the box). The glasses then appear as an external display, and their refresh rate is set in the system display settings like any other monitor. PCs that output over HDMI connect through the HDMI Adapter, whose output modes include 1080p at 120Hz. RayNeo's guide to AR glasses for PC gaming covers PC setups in more depth.
Handheld gaming PCs use the same direct USB-C route. Compatible USB-C handhelds connect directly, and Steam Deck is one of the representative devices for the GT series.
Consoles take the HDMI route. PlayStation 5 and Xbox Series X|S connect to GT and GT Max through the HDMI Adapter and the USB-C cable included with GT and GT Max, and Air 4 Pro also supports HDMI devices through the same adapter. Its 1080p at 120Hz output mode is the one that lines up with the glasses' native resolution.
Frame rates between 60 and 120
A display running at a fixed 120Hz refreshes every 8.3 milliseconds, and the game's frame rate decides how many of those refreshes receive a new image. When the source delivers a steady frame rate and presents each frame in sync with the refresh, 120fps puts a fresh frame on every refresh, and 60fps holds each frame for two refreshes, which keeps motion even at the 60fps pace.
Frame rates in between divide unevenly into 120. A game running at around 90fps with V-Sync can end up showing some frames for one refresh and others for two, and in fast camera pans that uneven rhythm can read as slight stutter even though the average frame rate is higher than 60.
Many PC games and handheld systems include a frame limiter, which sets the maximum frame rate. A 120fps limit suits games the source can hold at that rate. For a demanding game that can hold a steady 60fps but not 120, a 60fps limit helps keep frame timing even. On consoles, the setting to look for is a game's own 120Hz or 120fps mode, where the game offers one, together with the console's 120Hz video output option. The frame rate a game reaches is always set by the source device and the game's own settings.
Three strengths to weigh for fast-paced play
All three share a 1920×1080 resolution and a 120Hz refresh ceiling, so the better pick depends on the kind of game on the screen.
For open-world games, racing and anything cinematic, GT Max puts the widest picture in front of the eyes: a 59° field of view and virtual screen sizes of 227, 267 or 307 inches. Its S, M and L IPD sizes (under 64mm, 64 to 67mm, over 67mm) are chosen when ordering and align the optics with the distance between the pupils for a clearer, more comfortable view. It is the GT model aimed at movies, gaming and long viewing sessions.
For players who put pixel density first, GT is the option to look at. It is rated at 49 pixels per degree against 38 on GT Max, with a 46° field of view, and its 68g frame is the lightest here. GT uses a fixed 64mm IPD optical design, with nose pads for fine positioning.
Air 4 Pro fits players who want a straightforward screen that stays in front of the viewer in Follow Mode. It weighs 76g and shows a 201-inch virtual screen with a 46° field of view, and its display modes include a Game mode alongside Movie, Standard, Eye Protection, Professional and Vision Boost. Air 4 Pro is suitable for fast-paced gaming: compatible USB-C devices connect directly, and HDMI consoles connect through the HDMI Adapter.
GT and GT Max also carry Native 3DoF spatial tracking through the Zone 360 chip, which adds more ways to place the screen. The refresh rate and PPD explainer for GT Max goes deeper on how those two numbers relate.
Spatial and display settings for competitive play
On GT and GT Max, Follow mode keeps the screen centered as the head moves, so the game stays in front of the eyes. For a seated desk setup that should behave like a fixed monitor, Pinned mode holds the screen in one spot.
Screen size is the other setting to match to the game. GT Max offers 227, 267 and 307-inch sizes, with the largest suited to slower, scenic games where filling the view is the point.
Setting up a 120Hz session from plug to play
A short routine covers the whole chain before the first match:
- Connect the source, either directly from a USB-C port with DisplayPort video output or through the HDMI Adapter. GT and GT Max switch on automatically once they detect power and a video signal.
- Set the output to 120Hz. On a Windows PC, the advanced display settings list the refresh rate for the glasses as a separate screen. On a console, the video output settings control whether 120Hz is allowed.
- Set the game. Choose its 120fps mode where offered, or set its frame limit on PC to a rate the system can hold.
- Place the screen. On GT and GT Max, a short press of the Spatial Mode Button moves between the three spatial modes, Steady, Pinned and Follow, and the screen size can be matched to the game. On Air 4 Pro, the Game display mode is one of six display modes.
120Hz FAQ
Does 120Hz need a special cable?
GT and GT Max ship with a DisplayPort-compatible USB-C to USB-C cable. From a USB-C port with DisplayPort video output, that one cable carries video, audio and power to the glasses. Air 4 Pro connects directly over DisplayPort-compatible USB-C in the same way. HDMI sources add the HDMI Adapter between the console or PC and the glasses' USB-C connection.
What resolution do console games run at on the glasses?
The glasses use a 1920×1080 panel, and the HDMI Adapter's 1080p at 120Hz output mode matches that native resolution, so a console set to 1080p output feeds the glasses at their native resolution.
How can a PC user tell the glasses are running at 120Hz?
The glasses show up in Windows as an external display, and the advanced display settings list the refresh rate selected for each screen. Choosing the glasses there shows whether 120Hz is active. An in-game frame counter measures something different, the game's frame rate, which helps confirm the game is producing enough frames to use the faster refresh.
How many brightness levels do the glasses offer?
GT and GT Max offer 12 brightness levels plus 3 extra gain levels, and Air 4 Pro offers 20 levels. That range lets the screen be set to suit the room, from a bright daytime space to a dark evening session.
At 60Hz, a display draws a new frame roughly every 16.7 milliseconds (1,000 ÷ 60). At 120Hz that wait drops to about 8.3 milliseconds (1,000 ÷ 120), and when a fast game renders enough frames to match, the difference shows in camera swings and in a crosshair following a target across the screen.

A 120Hz picture also depends on the game and the device feeding it.
What 120Hz changes in motion and input timing
The shorter refresh interval gives the display twice as many chances per second to show a new image. When the game renders fast enough to fill those refreshes, camera pans and moving targets are drawn in more intermediate positions, which reads as smoother motion.
It can also shorten the wait between an action and its result on screen, because each refresh comes around sooner.
