I was having exactly the same problem on my Philips 231T. It's a 23inch LCD HDTV capable of running full-hd (1920x1080 aka 1080p). I could solve my problem, and I hope to help others with the following information.
I am using an Intel based MacBook (End2007 with the apparently poorly rated graphic card "Intel GMA X3100") and running 10.6.x. I am connecting to the monitor's HDMI input using a mini-DVI to HDMI adapter and an HDMI cable.
My symptoms where the following (using preferences > display):
- Selecting 1080p and "no overscan" the desktop image would not fill-in the whole monitor's frame (and looked more like 1600x900 then 1080p...)
- Selecting 1080p and "overscan" the desktop image would fill-in more than the monitor's frame, making the usage of the application's menu-bar just about impossible...
I have found many threads discussing tools to install, strange manipulation (reset of parameter RAM, etc). None of which helped...
In the end the solution was awefuly simple: I had to change a setting in the monitor's configuration!! On my Philips monitor it's called something like Picture > Extended Preferences > HDMI-Mode. I have the choices of "automatic", "video" and "graphic". In the two first modes, the desktop is wrongly displayed (as described above). As soon as I set the HDMI-Mode=graphic, the connection with my Mac was perfect...
For those of you out there struggling with similar issues I would recommend viewing a 1920x1080 image at 1:1 ratio (example Preview in Fullscreen mode with appropriate option settings). On example of which would be this picture:
In my case, when using overscan, the arrows would at first not be entirely visible. Now I see them entirely.
The post from "Ibenes" from 2009/12/28 was a real help for me in the following thread:
Here's what you do if you have the Best Buy Insignia LED-LCD 22" monitor that is in discussion and if you're unable to see the Apple menu bar on you TV using and HDMI input (haven't tried this for VGA)
Press Menu (on Insignia remote)
Scroll down & select ADVANCED VIDEO
SET OVERSCAN TO OFF!
Now make sure the MacBook is in it's highest resolution, that you're not doing Mirrored Images and you're good to go.
If you want to close the lid on the mac book you must have it connected to the AC power (i.e. not battery power) and use a bluetooth keyboard and mouse/trackpad. If you're using the older MacBook that uses cool airflow from keyboard space you may want to insure that you have proper ventilation and/or it's in a cooler place to prevent overheating.
Hope this helps someone, it took me forever to get my LEDTV to work but now it's awesome!
Probably the Insignia's built-in display driver (EDID) is missing this resolution so the Mac isn't offering it. There is a program called SwitchResX that is tailor made for these types of problems. One thing it can do is capture the EDID to a text file so that you can read it and determine if, in fact, the critical resolution is missing from the driver. More importantly, it can allow for the creation of the missing resolution, e.g. you'll be able to create a custom, 1920 x 1080 resolution that will be associated with BBY LCD TV and hence that choice will show up in Displays Preferences where currently it is not.
Hello, I just bought the 22" Insignia LED-LCD TV and a MiniDisplayPort to HDMI converter to connect my MacBook Pro with it but the text looks horrible in the Insignia TV, I've tried most of the things I've found on the web (terminal commands, third party software, Insignia Settings) however none of these has worked. How did you manage that "awesome" image? Thanks.
