Welcome to the Lenovo Community.
If you don't have the Full HD (1080p) version of the Y500 as listed in this pdf data sheet, you can still upgrade to a Full HD screen and you may not need to change the LCD cable as it is already an HD capable. You may need to patch the DSDT though when upgrading the resolution with dual link patch.
Hope this helps.
The problem is that I can't seem to find a dual link patch anywhere for the y500. I've searched a dual link patch for the 650m display adapter but no luck either. I don't think is that complicated but I have no idea how to do it.
Here's the high resolution fix for the HD4000 https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/graphics/graphics_HD4K_high.txt
I guess it should be similar for the 650m... or not?
Any help would be great!
