Here is what I did on the Linpus version to get 1080p display on my TV:
1) click "My Documents"
2) enter "/etc/X11" in the top field and hit the Enter key.
3) right-click on the xorg.conf file
4) select "Open with Mousepad"
5) Ctrl-F (or in the menus: Search -> Find)
6) enter "virtual" and hit Enter key
7) change that line from "Virtual 1024 768" to "Virtual 1920 1080"
8) change the line above from
.....Modes "1024x600" "800x600" "640x480"
.....to:
.....Modes "1920x1080" "1024x600" "800x600" "640x480"
9) File -> Save
10) click the power icon in the lower right corner of your display and click "Restart".
11) after reboot, wait about a minute, then hold the "Fn" key and hit the "F5" key twice, but not too fast- maybe 1 to 2 seconds apart.
I also got the Gear Head KB5500W wireless keyboard and mouse kit which just worked out of the box.
Now I have a gorgeous 42" computer monitor at 1920x1080 for my little One.
Very very happy.
If you have any problems, hit Fn-F5 once more to cycle back to the LCD screen only.
Note that the graphics processor uses the main system RAM for the display.
This may be working for me because I had added a 1gb memory module I ordered from
http://www.crucial.com.
That has my system now running with 1.5gb of memory.
And adding that memory was a MAJOR pain (mostly because several of the screws were really hard to turn- be VERY careful and patient!)
Anyways, the good news is that this little puppy CAN do full HDTV resolution just fine.
Also, I found that I had to have the TV on and set to display its PC signal first before switching with Fn-F5 in order for the Aspire One to output the correct signal.
In addition, the Settings/Display control on the Aspire One desktop does not reflect the 1080p option.
Maybe someone has a solution for that? The Fn-F5 works fine though....
