Panasonic 50" Plasma TH-50PH9UK - can mac mini display be set to 1366X768

Question

My mac mini is connected to a Panasonic high definition plasma display (TH-50PH9UK) using a DVI to VGA adapter and a VGA connector. The native resolution for the display is 1366 X 768 but this is not an option under the display settings in system preferences? How can I match the native resolution?

Answer 1

No guarantees, but try this (the following precedure must be performed with the Panasonic attached to the mini):
Download and install SwitchRes X Control Panel (note: not the full version called Universal Installer). Open SRX and with the "Resolutions" icon highlighted in the main window, click on the "Custom" button on the button bar. Click on the "+" in the lower left corner of the window to add a new resolution. A second window will open filled out with timing values of the current timing in use. Make sure the "Use simplified settings:" check box does not have a check mark in it. Fill in the boxes with the following data:
Pixel clock: 86.18
Horizontal Active: 1366
Horizontal Front porch: 40
Horizontal Sync width: 96
Horizontal Back porch: 280
Vertical Active: 768
Vertical Front porch: 3
Vertical Sync width: 14
Vertical Back Porch: 21
Put check marks in "Positive sync." for both Horizontal and Vertical sync.
You should observe that the Horizontal Scan rate is around 48.36 kHz and the Vertical Scan rate should be around 60 Hz. Click on the OK button and and then the Apply button. Quit SRX and follow the directions for saving and restarting.
When the mini is restarted, open Displays preferences and the newly created timing should now show up. Select it and hopefully you will get a native resolution output. Good luck.
