I contacted the Amazon Seller that I purchased the drive from since they advertise it is "full function UHD 4K Blu-ray playback with appropriate 3rd party software" just to ask what software they recommend as it's not working for me. Their reply:
"The 4K supports "plug and play", no need to install any driver programs.
To watch 4K blu-ray movies, your laptop must support 4K UHD, you need a blu-ray player application such as CyberLink PowerDVD. Please test it with different 4K blu-ray discs or other player software if it can't play properly.
Do not worry, I promise to resolve the problem smoothly and quickly.
Please do not file A-to-Z claim or leave negative feedback.
Looking forward to your fast reply."
After trying this, I wrote back:
"When I put a 4K disc into the drive, the drive still shows up in Windows as BD-RE Drive (D:) It does not register 4K discs.
This is the same in PowerDVD, where clicking on the drive shows "No media available"
This was the case with several 4K discs I tried. Blu-ray discs and DVDs work fine."
Then they got a bit defensive:
"It is built-in genuine LG BU50N or BU40N, which is the best 4K blu-ray drive in the world.
You can find the model number in hardware management, or in properties by right-click the optical disk icon.
It supports 4K UHD blu-ray definitely. We sold thousands pieces before.
To watch 4K blu-ray movies, your laptop must support 4K UHD, you need a blu-ray player application such as CyberLink PowerDVD.
Please test it with different 4K blu-ray discs or other player software if it can't play properly.
If the drive is defective, we'd like to send you a new replacement.
If you don't want to keep it any longer, please send it back for full refund."
The drive shows as empty when I insert a 4K disc. Hardware Management states it as: BD-RE BU40N. I'm also running Windows 11 if that makes any difference.
Any suggestions on what to do?
another way to tell is does the BU40N have the UHD logo on the front of the drive? but this can be misleading some without the logo are still official UHD.
