Blu-ray discs play in 1080p resolution, which is significantly better than the maximum resolution standard DVDs can play in. Unfortunately, the only way you can use Blu-ray discs is by inserting them into a Blu-ray player. If you have a newer computer, you may have a Blu-ray player. Older computers, especially those dating back to 2009 and prior, generally do not come with Blu-ray players. You can check to see if your computer has a Blu-ray player by looking at the computer itself or by accessing system information.

Look on the front of your computer. If you have a laptop, open the top to reveal the keyboard. You should see a label with your computer's specifications. Almost all computers that have a Blu-ray player will say so on the label.
Examine the face of your computer's disk drives. Just as DVD and CD-ROM drives are labeled as such, Blu-ray drive players will include "Blu-ray" on the front of the drive. Look closely, as the drive's label can be difficult to read if it's nearly the same color as the face of the drive.
Open the "Start" menu and enter "System Information" in the "Search" field. Press "Enter." Once the "System Information" window appears and loads, click the "+" icon next to "Components." Click "CD-ROM." The information on the right side will take a minute or so to load. After it does, look under each drive for "Media Type." If you have a Blu-ray player, the media type for one drive should read "Blu-ray."
