If your Samsung Odyssey 3D Hub launches, shows an error, and immediately closes on your G90XF monitor, Samsung attributes this to a compatibility problem with Windows 11 update KB5074105. The official fix is to update the Odyssey 3D Hub to version 1.3.5 or later, either from your model’s Samsung support page or through the Microsoft Store. Version 1.3.5 is the minimum version Samsung names for this fix — if a newer official release is available when you read this, use that instead. Do not start by removing the Windows update. And if the Hub actually opens but the Overlay UI won’t disappear, the monitor isn’t detected, or games stay in 2D, those are separate problems with separate steps below.
First, Identify Which Odyssey 3D Hub Problem You Have
“Odyssey 3D Hub not opening” covers several problems that don’t share one fix. Sort your situation into one of four groups: the Hub won’t launch, it opens and immediately closes, it opens but the Overlay UI stays on screen, or it opens but can’t detect the monitor or show 3D. The table below points you to the right section.
Use this quick diagnosis table to find your symptom and the first thing to check. “Most relevant issue” indicates where to start, not a confirmed cause.
| Symptom | Does the Hub stay open? | Most relevant issue | First check | Next section |
|---|---|---|---|---|
| Hub shows an error and closes right away | No | KB5074105 compatibility / old Hub version | Installed Hub version | Check the KB5074105 match, then update the Hub |
| Hub stopped opening after a Windows update | No | KB5074105 compatibility | Windows Update history | Check the KB5074105 match, then update the Hub |
| Hub window flashes and disappears | No | Old Hub version | Installed Hub version | Update Odyssey 3D Hub to version 1.3.5 or later |
| Hub opens, but the Overlay UI won’t turn off | Yes | Separate Overlay software bug | Hub version (Overlay guide) | Troubleshoot Overlay, detection, or 3D output separately |
| Hub opens, but the G90XF isn’t detected | Yes | Connection / model / firmware | Video and USB connections | Troubleshoot Overlay, detection, or 3D output separately |
| Hub opens and detects the monitor, but games stay 2D | Yes | PC specs / supported games / GPU | Supported game list | Troubleshoot Overlay, detection, or 3D output separately |
If the Hub stays open, skip the KB5074105 sections entirely — those cover launch-and-close failures only. Jump to the separate troubleshooting in the final section.
Check Whether KB5074105 and an Older Hub Version Match the Known Issue
KB5074105 is a Windows 11 preview non-security update for versions 24H2 and 25H2, released on January 29, 2026. Samsung attributes the G90XF launch-and-termination issue to a compatibility problem involving this update combined with an older Odyssey 3D Hub version. Before changing anything, confirm both your Windows build and your installed Hub version so you know whether your setup matches.
Check your Windows version and build first. Open Settings → System → About, or press Windows + R, type winver, and press Enter. To see whether KB5074105 is installed, open Settings → Windows Update → Update history and look under the quality or optional update entries.
Next, check your installed Hub version. Open Settings → Apps → Installed apps, locate Odyssey 3D Hub, and note the version number shown. If it is earlier than 1.3.5, your setup matches the app-version condition in Samsung’s documented fix. If it is already 1.3.5 or later, continue to the installation cleanup section instead of assuming that the Windows update is the only possible cause.
Use this table to check the components that matter, separating what affects Hub launch from what affects detection or 3D output.
| Component | Where to check | Required or recommended state | Why it matters |
|---|---|---|---|
| Windows 11 version | Settings → System → About, or winver | 24H2 or 25H2 | KB5074105 applies to these versions |
| Windows OS build | winver | Matches your update history | Confirms which cumulative update is installed |
| KB5074105 status | Settings → Windows Update → Update history | Installed / not installed | Identifies the update Samsung names |
| Odyssey 3D Hub version | Settings → Apps → Installed apps | 1.3.5 or later | Directly related to the documented launch fix |
| Monitor firmware | Monitor menu / Samsung download page | Correct file for your exact model code | Affects detection and 3D output rather than the documented Hub launch fix |
| GPU driver | Device Manager / GPU app | Supported driver | Affects supported 3D features and output |
Two cautions here. Samsung frames this as a compatibility issue between its Hub and this specific Windows update; this is not the same as Microsoft listing an Odyssey-specific problem as a general known issue. Microsoft currently states that it is not aware of any issues with KB5074105. And if you see the same launch-and-close behavior on a system without KB5074105 installed, treat it as a different cause and don’t force the KB explanation onto it.
Update Odyssey 3D Hub to Version 1.3.5 or Later
Samsung’s fix for the launch-and-close issue is to update the Odyssey 3D Hub to version 1.3.5 or later. Get it two ways: download the installer from your G90XF model’s Samsung support page, or update through the Microsoft Store. Version 1.3.5 is the minimum Samsung names — if the current official release is newer, use that instead.
Check your current version first. Open Settings → Apps → Installed apps, find Odyssey 3D Hub, and read the version. If it’s already 1.3.5 or later and the Hub still closes, skip ahead to the cleanup section.
The Samsung installer route takes these steps.
- Go to Samsung Support.
- Select Computing, then Monitors.
- Enter your model code in the search field (for example, LS27FG900XNXZA) and select your product. If you don’t know your model code, check the label on the back of the monitor, or press the JOG button and go to Menu → Support → Information.
- Select User Manual & Download.
- Under the Software section, select Download next to Odyssey 3D Hub (Installer), version 1.3.5 or higher.
- Run the installer and follow the prompts.
The Microsoft Store route is an alternative.
- Open the Microsoft Store.
- Search for Samsung Odyssey 3D Hub.
- Update to version 1.3.5 or later. You can also open the Store’s Library and check for pending updates there.
- Make sure Windows 11 itself is up to date to avoid further compatibility issues.
Do not download the Hub from a third-party or unofficial site. Use the Samsung support page for your exact model code or the Microsoft Store, then re-check the version in Installed apps to confirm the new build is in place.
Clean Up the Installation if the Updated Hub Still Closes
If you’re on version 1.3.5 or later and the Hub still won’t stay open, work through the installation carefully before assuming a hardware fault. The goal is to confirm the update actually applied, clear any leftover process or old build, and rule out a pending Windows update — using official or standard Windows steps only.
Work through these checks in order.
- Re-confirm the version in Settings → Apps → Installed apps. If it still shows an old number, the update didn’t apply.
- Check whether a Hub process is stuck. Open Task Manager, look for Odyssey 3D Hub, and end the task if it’s running in the background.
- Restart the PC normally, then try launching the Hub again.
- If the version is old, re-run the official Samsung installer, or check the Microsoft Store Library for a pending update.
- Look for a duplicate or leftover older install in Installed apps. If you uninstall and reinstall, use the standard Windows uninstall and the official installer only.
- Confirm no Windows update is pending in Settings → Windows Update, and finish any that are.
- Record the exact error text or behavior so you can give it to Samsung Support if needed.
Some general “fixes” are not appropriate here without official backing. Don’t disable your security software as a routine step, don’t treat running as administrator as a required condition, and don’t apply unofficial registry edits, replacement DLLs, or compatibility-mode tweaks. Event Viewer or crash-log inspection is an advanced, optional aid — not a required step. If the Hub still closes after all of this, the next move is contacting Samsung Support with your recorded details rather than escalating to risky workarounds.
If the Hub Opens, Troubleshoot Overlay, Monitor Detection, or 3D Output Separately
If the Hub opens and stays open, the KB5074105 launch fix doesn’t apply — a different problem is in play. Three issues get confused with the launch failure: the Overlay UI not disappearing, the monitor not being detected, and games not switching to 3D. Each has its own diagnostic path, and the update steps above won’t solve them alone.
Overlay UI won’t disappear. Samsung documents this as a separate software bug in Odyssey 3D Hub version 1.2.2, handled in its own support article rather than the launch-failure guide. Updating to the current Hub version is the starting point, but treat it as a distinct issue from the app closing.
Hub opens but doesn’t detect the G90XF. Confirm that the monitor matches your exact model code, then check the selected input, the video and USB connections, and the monitor firmware. Download firmware only from Samsung’s support page for that exact model code; do not use a file chosen only because the product name looks similar.
Hub detects the monitor but games stay in 2D. This depends on Samsung’s PC requirements, your GPU and graphics driver, the supported game list, how the game is launched, and any multi-monitor conditions. Verify each against the official materials for your model rather than assuming — and don’t explain a 2D-only result with KB5074105, which is about the app launching.
Across all three, don’t assume the monitor hardware is defective just because detection or 3D fails. Confirm the software, connection, model, and firmware first, and contact Samsung Support if the issue continues after those checks.
Frequently Asked Questions
Why does Samsung Odyssey 3D Hub close immediately on my G90XF?
Samsung attributes the launch-and-close behavior on the G90XF to a compatibility problem involving Windows 11 update KB5074105 and an older Odyssey 3D Hub version. The documented fix is updating the Hub to version 1.3.5 or later from the Samsung support page or the Microsoft Store, rather than removing the Windows update.
Did Windows 11 update KB5074105 break Odyssey 3D Hub?
Samsung describes this as a compatibility issue between the Hub and KB5074105 on the G90XF. That is not the same as Microsoft listing an Odyssey-specific problem as a general known issue. If you see the same behavior without KB5074105 installed, treat it as a separate cause.
Which Odyssey 3D Hub version fixes the KB5074105 issue?
Samsung names version 1.3.5 or later as the fix. Treat 1.3.5 as the minimum version, not a fixed “latest” release. If a newer official version is available for your model when you check, install that instead of forcing an older number.
Should I install Odyssey 3D Hub from Samsung or the Microsoft Store?
Both are official. You can download the installer from your G90XF model’s Samsung support page, or update through the Microsoft Store. Use whichever offers version 1.3.5 or later, and never use third-party download sites.
Should I uninstall KB5074105 to fix the Hub?
Removing the Windows update should not be your first step. Samsung’s guidance is to update the Odyssey 3D Hub instead. Prioritize the official app-update fix, and only consider update-history changes with caution if the documented fix does not resolve your case.
Why does the Hub open but not detect my G90XF, or show games in 2D?
Those are separate from the launch failure. Detection issues point to model, input, connection, or firmware; 2D-only output points to PC specs, GPU driver, and the supported game list. Verify each against official sources rather than assuming the monitor hardware is defective.
How We Researched
This article is based on manufacturer documentation and official support materials. For this guide, we reviewed Samsung’s US support articles on the G90XF Odyssey 3D Hub launch issue and its separate Overlay issue, Samsung’s product and software information for the model, and Microsoft’s official update information for KB5074105. We have not conducted hands-on lab testing. Version numbers, compatibility claims, and update procedures are attributed to official sources, and version-specific details are framed so readers can confirm the current release for their exact model.
Conclusion
If your Odyssey 3D Hub launches and immediately closes on the G90XF, start with Samsung’s documented fix: confirm your Windows build and Hub version, then update the Hub to version 1.3.5 or later through the Samsung support page or the Microsoft Store, using the current official release if it’s newer. Don’t lead with removing KB5074105. If the app still closes after updating, work through the installation cleanup with official steps only. And if the Hub opens but the Overlay won’t clear, the monitor isn’t detected, or games stay 2D, those are separate problems with their own steps — check the software, connection, model, and firmware before assuming a hardware fault, and contact Samsung Support with your recorded details if the issue continues.
