NVIDIA Releases Patch for RTX 50 Series to Fix Video Stuttering and Black Screen Issues
On October 27, NVIDIA released the 621.12 hotfix driver to address a problem introduced by its own 621.01 release six days earlier: RTX 50 series graphics cards would freeze or go black for a few seconds during video playback.
What the Affected Screens Look Like
The symptoms have three characteristics. When watching videos in a browser, the screen freezes for a few seconds and then recovers on its own without a restart; users of Chrome, Edge, and VLC player have all reported it; the strangest one is that opening a game while a video is playing in the browser also causes the screen to go black briefly.
Traces can be found at the system level. Windows Event Viewer shows Event ID 153 related to nvlddmkm, and a few also come with LiveKernelEvent 141 or 117. These codes are all recovery records after a GPU timeout, which matches a driver crash, but the codes alone can't determine the root cause, and NVIDIA hasn't disclosed it either.
As for affected cards, the official statement only says "some RTX 50 series," with user reports concentrated on the 5080, though some 4090 users say they've been hit too.
Six Days from Breakdown to Patch
On October 21, 621.01 was released, focused on optimizations for Phantom Blade Zero and Call of Duty: Modern Warfare 4, and also added support for Microsoft's Advanced Shader Delivery.
Three days later, on the 24th, NVIDIA forum staff member Manuel confirmed in a feedback thread that a bug report had been filed and asked affected users for WATCHDOG crash dumps, located at C:\Windows\LiveKernelReports\WATCHDOG, with feedback sent to driverfeedback@nvidia.com. On the 27th, 621.12 was posted to the support page.
In the days in between, the community found its own workaround: rolling back to 617.42 from October 6 made the black screens stop. This conclusion comes from user reports; NVIDIA didn't write it up as an official solution, but at least it shows the problem lies in the 621.01 release. 621.01 belongs to the R620 driver branch — and the first release of a new branch broke.
The hotfix channel exists precisely for this kind of situation. It skips WHQL certification, has a shorter validation process, and producing a patch in six days is fast by graphics driver standards.
Four Fixes, Only One Applies Across the Board
| Fix | Hardware Involved |
|---|---|
| Video playback freezing or black screen | Some RTX 50 series GPUs, RTX Spark systems |
| Unreal Engine 5.8 crash in Hit Lighting mode | Not limited to 50 series |
| Corrupted display when RTX Spark connects to StarTech Thunderbolt 3 to HDMI 2.0 adapter | RTX Spark |
| Intermittent screen flickering on MSI N16 Flip | That model |
Of the four, only the UE5.8 item is not limited to the 50 series. In other words, the video black screen reported by 40 series users is not covered by this fix list.
To Install or Not, Three Cases
If you're already getting black screens, install 621.12. It's based on the latest Game Ready driver and fixes exactly this video issue.
If you're not getting black screens, you can wait. 621.12 is an optional beta driver with a shorter validation process than the official release, and NVIDIA says these fixes will be merged into the next official driver. For those not affected, waiting a few more days is safer.
For 40 series users hitting the same symptoms, the available option right now is still rolling back to 617.42, and waiting for the official channel to incorporate 40 series feedback into the next version.
When downloading, check the installer package: there are Windows 10 and Windows 11 x64 versions, and RTX Spark has a separate Windows 11 ARM64 version.
For regular users, the easiest approach is to avoid the first release of a major version. When a new driver branch first comes out, no matter how many test machines a vendor has, it can't cover everyone's screens and cables — upgrading one or two versions later greatly reduces the chance of stepping on a landmine.
RTX Spark, Eleven Days on the Market
RTX Spark went on sale October 16, with 617.42 WHQL as the launch driver. By the 27th, a full eleven days, the first new driver it received was a firefighting patch.
This machine is a superchip combining a Grace CPU with a Blackwell GPU, running Windows 11 ARM, with its driver maintained separately. It has more combinations to manage than a desktop: external monitors, adapter dongles, laptop panels, browser hardware decoding — if any link is off, the screen goes black. A new machine getting an emergency fix eleven days after launch shows just how wide the surface drivers have to cover these days.
What to Do
First, check two things yourself. Open NVIDIA App or Device Manager and see if the driver version is 621.01; then recall whether the problem only occurred in browsers and players, while games didn't go black. If both match, installing 621.12 or rolling back to 617.42 will both solve it — installing the patch is less hassle, rolling back is more stable.
