iMac Screen Replacement: Original Vs. Copy

The original display for the iMac might be difficult to find; the following are some ideas.

1) Different brightness

When you look at the original LCD of an iMac screen, it is bright, and when you look at the brightness of the copy, it is considerably dimmer than the original, even when the brightness is set to full. If you’re still perplexed, compare your iMac’s screen to that of another iMac.

2) Move the mouse over the Software Icon.

If you click and hold any icon and drag it over other icons, the original screen programs will move quicker and the copy will not operate correctly.

3) The barcode

On the rear of the original iMac’s LCD, there is a barcode as well as the serial number. Although the barcode and serial number are often included on the copy, the original display has a large, legible barcode, while the replica only has a small one.
