Have you encountered any strange problems with video playback on your latest device?
Have you encountered any strange problems with video playback on your latest device?
Hello everyone,
I’m dealing with an extremely unusual issue that I haven’t encountered before. It’s been challenging me over the past three days, and I’m really hoping you can guide me through it.
I recently assembled a new PC equipped with a 9800X3D graphics card, 64GB DDR5 RAM at 6000MHz CL30 speed, and a Gigabyte 5090 motherboard. The system runs smoothly on Windows 11, but the main concern is related to my display setup.
I have two monitors and one TV connected to the GPU. The primary monitor uses a 240Hz GSYNC connection to DP1, while the second monitor is set to 120Hz via GSYNC to DP2. The LG TV is connected to an HDMI port that only the GPU has access to. I’m using NVIDIA driver 576.28, which is the only stable driver for my 5090; any newer drivers seem to cause problems.
When playing videos in VLC or other media players, everything runs smoothly on both gaming monitors. However, when dragging the window to the LG TV, it feels like the frame rate drops to just 10 frames per second—sluggish and strange.
I’ve tested Netflix Desktop, Stremio, and others, but they all exhibit the same low framerate issue. Interestingly, playing YouTube videos in Chrome works perfectly at 60fps.
Here’s the odd part: streaming a YouTube video through the Chrome browser is smooth, but with the TV, it stutters significantly.
Please help me figure out what’s going on. I really appreciate your assistance!
Thank you!
I have assembled a new PC featuring 9800X3D, 64gb DDR5 6000mhz CL30 RAM and Gigabyte 5090.
When sharing a troubleshooting thread, it's standard to provide complete system details. Please outline the specifications as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the PSU age along with its make and model. BIOS version for your motherboard at this stage.
Attempt to disable the iGPU in BIOS, then use DDU to eliminate all GPU drivers (Intel, AMD, Nvidia) in Safe Mode. Finally, install the newest GPU driver from Nvidia's support site via an elevated command, such as right-clicking the installer and selecting Run as Administrator.
Thank you, I've updated the post to reflect that the BIOS is using the latest version, the iGPU is turned off in the BIOS, and the AMD software has been removed using DDU. Only NVIDIA drivers are installed for version 576.28.
I understand you don’t want to set up the newest NVidia driver if it caused issues before. I think you’re likely using the Gaming driver; I favor NVidia’s Studio version for my video editing machines since it tends to perform better. My rigs have an RTX3060 and an RTX 4070, so any specific problems with the RTX 5090 aren’t my concern.
Which HDMI cable are you employing? Does it support HDMI 2.0 or 2.1? It should work fine for streaming Netflix, though it’s worth verifying.
I’ve looked at this before: https://www.ncesc.com/gaming-faq/what-is...r-4k-60hz/
If you adjust the HDMI output frame rate to 30Hz on your TV, what effects do you notice?
I also installed MadVR to enhance Media Player Classic - Home Cinema (part of K-Lite codec pack) a while back. I don’t recall the reason, and it’s been quite some time.

Please be careful – if you add K-Lite, select Advanced Setup and avoid third-party additions.

Initial steps could involve removing the 30Hz connection to observe potential improvements, and another option would be turning off one of the gaming monitors to check for differences (this should work with a 5090).
Thank you for your reply, the cable is HDMI 2.1 the same one I used before on my old PC, just connected to this new one. I've adjusted the TV's HZ settings to 30hz, 29hz, 59hz, and 24hz, but the color format switches between RGB and YCBR while the video remains choppy.
I have already attempted that now and the result remains unchanged. I tested various settings like 24/30/59/60hz, optimized graphics, turned off optimization for windowed games, disabled VRR and HAGS, and switched HDMI to DP. Still, nothing has improved. I also tried using a reduction HDMI>DP connection and plugging the TV into my third DP slot on the GPU, but the issue persists. It seems like the problem lies between the TV and the GPU.
I’m about to introduce something unexpected to further complicate things.
When I play a local shadowplay recording of my gameplay in VLC, it runs smoothly at 60 fps!
This leads me to consider codecs or formats.
Other video files cause stuttering.
Chrome works without issues, dragging the Netflix window to the TV seems fine, but streaming Stremio causes stuttering.
It’s really puzzling what’s happening!
It seems confusing at first, but it almost resembles whether acceleration is actually functioning or not. The issue here is that there are no problems with your two monitors, only the TV. You might want to check CPU/GPU usage while playing something problematic on the TV and also compare both when it runs on a monitor. I don't see any indication that refresh rate was an issue during testing.
I was suggesting you should cap the GPU output at 30Hz, not the TV. Apologies if that wasn't obvious.
I'm uncertain about how to set a TV's refresh rate to a specific value. I believe my TV adapts to the FPS coming from the GPU on my media PC. If I set a higher FPS, the TV may freeze.
My 2017 OLED device supports up to 30fps via HDMI, but my main monitor is 50Hz, so it runs at 25fps (PAL).
The TV operates at a consistent 60hz, which is typical for older models. The previous PC was capable of handling this frequency via the HDMI port on the GPU (RTX 3080), so it should work fine. I adjusted the refresh rate using my NVIDIA control panel and Windows display settings. Are there other suggestions you'd like to explore?
