Invalid format when connecting macbook pro to lg tv

SOURCE: usb harddisk problem on LG 50PT81+ not compatibel XP

LG have created a solution that only allows you to backup to a hard disk in the format that they have created.
The hard disk can not then be read by a computer as they only recognize formats such as NTFS, FAT or FAT32: not LG´s format!!!

If you reformat the disk in FAT32 format then you can copy files to the hard disk and see your photos, or certain types of DIVX files and listen to music via your TV,......BUT...you can not save TV programs from the TV to the same hard disk UNLESS you allow the TV to reformat the hard disk to LG´s format ) in which case you will lose all the files you previously had on the hard disk.

In practice LG have created a backup solution that is of little use to most users particularly bearing in mind that the backup takes almost as long as the original programs and as long again to restore.

Most of LG´s products are very clever and have a tendency to be in advance of the market.

However on this occasion LG almost had a good idea but many users are going to feel tricked like I did,

There is nothing wrong with the connection, your TV or computer. Just changw the resolution settings under the display properties. Start with the lowest setting 800X600 and move your way up. It will eventually appear.
