Frequently Asked Questions

Display EX is a free Windows utility for advanced display management. It lets you create named display profiles that save your monitor configuration — resolution, refresh rate, HDR mode, DPI scaling and colour settings — and switch between them instantly.

It fills the gaps left by Windows Display Settings: per-app profile triggers, reliable DPI overrides for blurry apps on 4K screens, multi-monitor preset management and granular HDR tuning.

Yes. Display EX is free to download and use. There is no paid tier, subscription or feature gating. Download the installer here.

Display EX is developed and maintained by the Display EX team. The project is distributed via the official GitHub Pages site. For security and signing details, see the Privacy & Security page.

From the official Download page. This is the only authorised source. The installer file is CDXWin64v1.10.33.exe.

The installer is code-signed, so Windows SmartScreen will recognise the publisher and will not show a blocking warning. If you downloaded from the official download page and the SHA-256 hash matches, the file is authentic.

Some heuristic-based antivirus engines may flag display driver utilities as potentially unwanted — this is a common false positive for software that interacts with Windows display APIs. See the Security page for the verified hash and publisher certificate details.

Open PowerShell and run:

Get-FileHash CDXWin64v1.10.33.exe -Algorithm SHA256

Compare the output hash with the SHA-256 value listed on the download page. If they match, the file is intact and authentic.

Yes — the installer requires administrator rights (UAC elevation) to write to Program Files and register the display management service. This is standard for any Windows display utility. The app itself runs in the system tray with normal user rights after installation.

Go to Windows Settings → Apps → Installed apps, search for Display EX and click Uninstall. Alternatively, use the uninstaller in the Display EX program folder. All registry entries and profile data are removed on uninstall.

Yes. Display EX provides per-app DPI overrides and ClearType adjustments that restore sharp text and correct UI scaling for any application. See the step-by-step blurry apps fix guide for full instructions.

You can associate any saved display profile with one or more executable files. When Display EX detects that a configured application is launched, it automatically switches to the assigned profile. When the app closes, it can optionally restore your previous profile. See per-app profiles explained for more detail.

Right-click the Display EX system tray icon to see a list of all saved profiles — click any to switch instantly. You can also assign global keyboard shortcuts to your most-used profiles from Settings → Hotkeys.

Yes. You can toggle HDR on or off per profile, adjust peak brightness for OLED panels and save HDR state as part of any preset. See the HDR setup guide for a walkthrough.

Yes. Display EX lists all refresh rates supported by your monitor and GPU combination, including 120 Hz, 144 Hz, 165 Hz, 240 Hz and fractional rates like 59.94 Hz. You can set different refresh rates per profile — for example, 240 Hz for gaming and 60 Hz for battery saving. See the 144 Hz setup guide.

Display EX supports Windows 10 version 1903 and later (64-bit) and all editions of Windows 11. 32-bit Windows is not supported. See the full system requirements page.

Yes — Display EX works with all three GPU vendors via standard Windows Display APIs (DXGI / CCD). No vendor-specific drivers or SDKs are required. Tested with AMD RDNA 2/3, NVIDIA RTX 20/30/40-series and Intel Arc/Iris Xe.

Yes. Display EX detects monitors connected via USB-C (DisplayPort Alt Mode), Thunderbolt 3/4, HDMI and standard DisplayPort. Docking station pass-through displays are also supported.

Yes. Display EX supports silent installation via command-line switches for use with software deployment tools (SCCM, Intune, PDQ, etc.). See the Enterprise deployment guide for the full syntax and MSI packaging details.

Yes. Profiles can be exported as JSON files and deployed to user machines via group policy or a logon script. Display EX will import them on first run. Refer to the Enterprise page for the profile schema and deployment examples.
