The PlayStation 5 (PS5) is celebrated for its ability to serve as both a gaming console and a media center, capable of playing 4K Blu-ray discs. However, some users have encountered a frustrating issue: a green bar appears at the top of the screen when playing certain 4K Blu-rays, accompanied by shifted colors. This issue occurs regardless of the display device, whether it's an LG OLED, Samsung LED, or even an Epson projector. Interestingly, regular Blu-rays play fine on the PS5, and standalone 4K Blu-ray players like LG, Panasonic and Sony models do not experience this issue.

If you're experiencing this problem, you're not alone. Below, we’ll explore the causes of the green bar issue, why it happens on the PS5, and how you can resolve or prevent it using tools like Yuhan 4K UHD Creator.

Part 1. Why Does a Green Bar Appear at the Top of Some 4K Blu-rays on PS5

The green bar issue is rooted in how certain 4K Blu-rays are encoded. Specifically, the problem arises with 4K Blu-ray discs encoded using Nvidia GPU acceleration to process HEVC (High Efficiency Video Coding).

The Core Issue: Resolution Mismatch

4K UHD Blu-ray discs typically have a resolution of 3840x2160 pixels. However, Nvidia GPUs encode video widths and heights in multiples of 64 bytes for efficiency. Unfortunately, 2160 pixels (the height of 4K UHD) is not a multiple of 64. Instead, Nvidia's encoding adjusts the height to the nearest multiple, resulting in a resolution of 3840x2176 pixels.

This creates an extra 16 pixels (2176 - 2160 = 16) at the top of the video frame. These pixels manifest as a green bar during playback. Standalone 4K Blu-ray players are designed to compensate for this discrepancy and crop out the extra pixels. However, the PS5 lacks this functionality, leading to the visible green bar.

Why standalone 4K UHD Blu-ray players are not affected

Standalone 4K Blu-ray players are not affected by the green bar issue because they are specifically designed to handle a wide range of video encoding scenarios. These players can automatically crop or discard extra pixels, such as the additional 16-pixel height (2176 instead of 2160) caused by Nvidia GPU acceleration during HEVC encoding. Their firmware includes advanced playback algorithms optimized for Blu-ray standards, ensuring the video resolution and aspect ratio are correctly displayed, eliminating artifacts like green bars.

Part 2. How to Avoid the Green Bar Problem with Yuhan 4K UHD Creator

Steps to Avoid the Green Bar Problem with Yuhan 4K UHD Creator:

Before we start, we need to download and install Yuhan 4K UHD Creator. If your computer is Windows, you can click the button on the left below to download it. If your computer is Mac, please click the button on the right below to download it.

Step 1: Add Video Files

To begin creating a UHD Blu-ray, launch the software and select the "4K UHD" tab at the top. Add video files by clicking "Add Video" or simply dragging and dropping them into the main interface. For videos with multiple audio tracks and subtitles, you can easily choose your preferred options from the audio track and subtitle dropdown menus. External subtitles can also be added as needed. At the bottom, set the disc capacity (BD25, BD50, BD66, BD100) and frame rate. Keep in mind that most UHD Blu-ray players currently do not support writable BD66 and BD100 discs.

Step 2: Video Settings (Optional)

Click the "Edit" button next to the loaded video to open the video settings window—this step is optional. In this window, you can precisely adjust the video's start and end time down to milliseconds. Additionally, you have the option to set chapters manually. If the video already includes chapter information, Yuhan 4K UHD Creator will automatically import it for your convenience.

Step 3: Disk menu settings

Click the "Select Menu" button to access the menu settings dialog. Yuhan 4K UHD Creator offers a variety of menu templates with extensive customization options. You can choose from four scene display modes: chapters or files, displayed as icons or text. Additionally, you can modify menu text properties, including font, size, underline, line breaks, and more.

The software also supports a "First Play" feature, enabling a video clip to play automatically when the UHD Blu-ray is inserted, before the menu appears. This is ideal for introductory videos, sponsor logos, concept clips, or other pre-menu content.

Step 4: Advanced Settings

Step 5: Output Settings

Yuhan 4K UHD Creator allows you to save your projects as BDMV folders, ISO images, or burn them directly to discs. The Blu-ray discs it creates are highly compatible and work with nearly all Blu-ray players. Additionally, you can specify the Blu-ray burner, set the disc label, and more for a tailored burning process.

Step 6: Start authoring

Once you click the "Start" button, Yuhan 4K UHD Creator will begin the creation process. When the disc is ejected, the production is complete, and your Blu-ray is ready to use.

Part 3. Conclusion

The green bar issue when playing 4K Blu-rays on the PS5 can be frustrating, but it’s not insurmountable. The problem stems from how certain discs are encoded using Nvidia GPU acceleration, which adds extra pixels to the resolution. Since the PS5 lacks the ability to crop these extra pixels, the green bar becomes visible during playback.

The easiest way to resolve this issue is to avoid Nvidia GPU encoding when creating or re-encoding 4K Blu-rays. Yuhan 4K UHD Creator is an excellent tool that allows you to bypass the problem entirely by using software encoding. This ensures that your 4K Blu-rays play seamlessly on the PS5 without any visual artifacts.

By taking the steps outlined above, you can continue to enjoy both gaming and flawless 4K Blu-ray playback on your PS5, making it the ultimate all-in-one entertainment system.
