No, a Ray-Ban frame with regular, non-Ray-Ban lenses would not have the Ray-Ban logo on the lenses. The logo is typically found on the lenses of authentic Ray-Ban sunglasses, so if the lenses are not made by Ray-Ban, they would not have the logo. However, the frame itself may still have the Ray-Ban logo or branding on it. **

Blu-ray and 3D Blu-ray are both optical disc formats used for high-definition video playback. The main difference between the two is that 3D Blu-ray discs are specifically designed to support 3D content, allowing for a more immersive viewing experience with compatible 3D televisions and glasses. Regular Blu-ray discs can only display 2D content, while 3D Blu-ray discs can store both 2D and 3D content, making them more versatile for consumers who want to enjoy both types of content on their home entertainment systems. **

There could be several reasons why the Blu-ray drive is not recognizing the Blu-ray disc. It could be due to a dirty or damaged disc, a problem with the drive itself, outdated firmware, or compatibility issues between the disc and the drive. It is recommended to try cleaning the disc, updating the drive's firmware, and checking for any physical damage to the drive or disc. If the issue persists, it may be necessary to seek professional help or consider replacing the drive. **

You can play a Blu-ray without a Blu-ray player by using a computer with a Blu-ray drive and compatible software. There are also external Blu-ray drives that can be connected to a computer or laptop to play Blu-ray discs. Additionally, some gaming consoles, such as the PlayStation 4, are capable of playing Blu-ray discs. Lastly, there are Blu-ray disc players available that can be connected to a TV or monitor to play Blu-ray discs. **

Blu-ray 3D refers to a format that allows for viewing movies and content in 3D, providing a more immersive experience with depth perception. On the other hand, Blu-ray 4K refers to a format that offers ultra-high-definition resolution, providing sharper and more detailed images with four times the resolution of standard Blu-ray. In summary, Blu-ray 3D focuses on enhancing the visual experience with 3D effects, while Blu-ray 4K focuses on delivering superior image quality with higher resolution. **

Yes, you can watch regular Blu-ray DVDs on 3D Blu-ray players. 3D Blu-ray players are designed to be backwards compatible with regular Blu-ray discs, so you can still enjoy your existing Blu-ray movie collection on a 3D player. However, the regular Blu-ray discs will not play in 3D on a 3D player unless they are specifically formatted for 3D viewing. **

Blu-ray refers to the high-definition optical disc format used for storing and playing back high-definition video and audio. SD on Blu-ray, on the other hand, refers to the standard definition content that is included on a Blu-ray disc. While Blu-ray offers high-definition video and audio quality, SD on Blu-ray provides lower resolution video and audio for compatibility with older playback devices. Blu-ray discs can contain both high-definition and standard definition content, allowing for flexibility in playback on different devices. **

There could be a few reasons why you are unable to play the Blu-ray even though you have a Blu-ray and a USB Blu-ray drive. One possibility is that the Blu-ray disc may be region-locked, meaning it can only be played on Blu-ray players that are set to the same region code as the disc. Another reason could be that the Blu-ray drive may not be compatible with the specific type of Blu-ray disc you have, such as a 3D Blu-ray or a 4K Blu-ray. Additionally, there may be software or driver issues with the Blu-ray drive or the computer that is preventing the disc from being recognized and played. **
