Plug into DisplayPort 1.4, set 3440 x 1440 in Windows, then raise the refresh rate to 120Hz by hand. Windows defaults a new panel to 60Hz far more often than people expect. After that, switch Adaptive-Sync on in both the graphics driver and the monitor menu.
Unboxing a new ultrawide and leaving every setting on its factory default is the single most common way people end up running an expensive panel well below what the spec sheet actually promised. Setting up a 34-inch ultrawide monitor properly takes about ten minutes, and every step below fixes something Windows or the monitor itself defaults to incorrectly.
Plug into DisplayPort 1.4 rather than HDMI, set 3440x1440 in Windows display settings, then manually raise the refresh rate to 120Hz, since Windows defaults a new panel to 60Hz far more often than people expect. After that, switch on Adaptive-Sync in both the graphics driver and the R5,999 monitor's own menu, since both need to agree for the feature to actually function.
This decision has to happen before Windows is even involved, since it determines what the rest of the setup can achieve.
Roughly 26Gbps of headroom on DisplayPort 1.4 is what makes 3440x1440 at a full 120Hz possible in the first place, comfortably clearing the roughly 24Gbps that combination actually needs uncompressed; HDMI 2.0's closer-to-18Gbps ceiling simply cannot carry both at once. If your graphics card and the monitor both have a DisplayPort connection available, use it from the start rather than the HDMI cable that may have shipped in the box, since starting with the wrong cable means every following step is capped before it begins.
Windows occasionally defaults a new monitor to a lower resolution than it supports, particularly right after first connection.
Open Settings, then System, then Display, and confirm the resolution dropdown reads 3440 x 1440 rather than a lower option. If 3440x1440 does not appear as a choice at all, the cable or the graphics card driver is the likely cause rather than the monitor itself, since a properly connected DisplayPort 1.4 link should always offer the full resolution as an option.
This is the step almost everyone skips, because Windows rarely makes it obvious that a lower refresh rate was silently chosen.
Under the same Display settings page, look for Advanced display settings and confirm the refresh rate reads 120Hz, not 60Hz. Windows defaults new monitors conservatively far more often than most people realise, meaning a panel fully capable of 120Hz can sit running at 60Hz indefinitely until someone manually changes it. This single setting is responsible for most of the "why doesn't my new monitor feel faster" questions that follow an otherwise correct setup.
The final step needs two separate switches flipped, and missing either one leaves the feature inactive despite appearing correctly configured.
In your graphics card's driver software, AMD cards call the setting FreeSync while NVIDIA cards call it G-SYNC Compatible, both referring to the same underlying Adaptive-Sync standard that on this panel runs across roughly a 48Hz to 120Hz window. Separately, open the monitor's own on-screen menu and confirm Adaptive-Sync, or an equivalently named setting, is switched on there too. Both sides need to agree for tearing and stutter to actually disappear; enabling only the driver setting or only the monitor setting leaves the mismatch problem exactly as it was.
Once set up, compare your experience against the office monitor range and dedicated gaming setups to see whether additional accessories would round out the desk, and check cable solutions if you need a proper DisplayPort cable to replace whichever one shipped in the box.
Windows often defaults a new monitor to 60Hz and sometimes a lower resolution, so the improvement is not visible until refresh rate and resolution are both manually confirmed.
HDMI 2.0 works but falls short of the bandwidth needed for the full 3440x1440 at 120Hz combination. Use DisplayPort 1.4 for the complete specification.
Confirm the setting is switched on in both your graphics card's driver software and the monitor's own on-screen menu, since both need to agree for it to function.
Look at which port the cable is actually plugged into first, and make sure your graphics card driver is current too, ideally updated within the last 6 months, since an old driver can quietly cap the refresh rate options Windows offers.
No, not at all. All it changes is the exact moment each frame gets drawn, leaving colour and contrast settings completely untouched throughout.

Gaming PC lagging often comes from network delay, background apps, heat, storage issues, or mismatched settings. Work through quick checks before spending on parts for an SA gaming setup, then retest one change at a time.

Steam content servers unreachable needs a download-path check, not an immediate reinstall of every game. Restart the client, inspect download settings and compare another connection when practical. Clearing the download cache is separate from deleting installed games.
Keychron G6 HE has built-in and swappable battery versions with different weights. The product brief lists 42g and 46g respectively, each with a 3g tolerance. Choose by grip and battery preference before treating one headline weight as universal.
Corsair HS80 v2 MAX supports 2.4GHz wireless and Bluetooth. Its maximum battery figures use RGB-off conditions and differ by connection. Check microphone routing, comfort and the exact device support before assuming every wireless mode behaves alike.
Windows taskbar notification badges can be shown or hidden in Taskbar behaviours. This changes the small app indicators, not the underlying messages. Choose a calmer desktop while keeping a deliberate routine for checking important conversations and app updates.
Windows title bar window shake can minimise other open windows when you shake the active window by its title bar. Inspect the Multitasking setting and switch it off if that gesture interrupts your work. The preference costs R0 and does not require new hardware.
Windows Print Screen opens Snipping Tool when its keyboard preference is enabled. Change the option under Accessibility, Keyboard to choose another workflow. Test whether you need a clipboard image or a saved file.
Windows desktop icons missing may be a visibility setting. Right-click the desktop, choose View and inspect Show desktop icons. If only system icons are absent, use Desktop icon settings. Check the Desktop folder before assuming files were deleted.
Windows set time zone automatically greyed out calls for a location and device-policy check. Automatic time-zone selection relies on location services. A manual time-zone choice is separate from synchronising the clock; check both before replacing hardware.
Windows transparency effects can be switched off to make supported backgrounds more opaque. Use Accessibility, Visual effects or the colour settings, then compare a menu against your wallpaper. This R0 preference changes appearance; it is not a promised.
YouTube no sound is worth checking at the player, browser and device levels first. Unmute the video, check the selected audio output and compare another clip and app. These R0 checks help narrow the fault without assuming that speakers or headphones need replacement.
iPhone overheating needs a cooler environment and a pause in demanding activity. If a temperature warning appears, Apple advises turning the device off and letting it cool away from sunlight. Charging may slow or stop automatically; this protection is not proof of a.
