The monitor will only display 1440x900, because of the macbooks limits.
I changed the resolution for the external, and it tells me "Usable resolution is 1440x900". I do have them on the "mirror displays" option. When I dont have that clicked I only get the mac background on the monitor.
10.5.something I want the tv to show what my computer shows, but at a higher resolution. What option would that be? Or is that not possible?
I think that you're changing direction a bit here. You started this thread saying that you couldn't get your external monitor to display a higher resolution (1920 x 1080) than your Macbook's display (1440 x 900).
Now you're talking about a "TV"! This is a different situation. If you want the TV to show what the computer shows...then that's "mirroring" mode. If the maximum resolution on your Macbook is 1440 x 900...then that's the highest resolution you will be able to "mirror" on your TV.

It's not a TV sorry. I just use it as a TV. It is an external monitor.
The monitor is capable of 1920x1080 but the macbook only goes up to 1440x900. The monitor will only display 1440x900, because of the macbooks limits. Is there any way for the monitor to display full 1920x1080? Thanks.
Yes. Use clamshell mode. See this LINK.
