Hi,
I hooked up my MacMini to a Sharp LC-42RD1E via MiniDisplayPort to HDMI.
After some reading in this forum I achieved to have a resolution of 1216x680 (by starting at 1280x720 with overscan and reducing with SwitchResX to fit my screen). The result is however not satisfying at all.

Which other resolution should I try in the light of the EDID of the Sharp, which I display below. What is the difference between the timings in the Monitor Description blocks, the standard CEA Timings in the EXTENSION EDID BLOCK 1 and the detailed timing blocks?
The standard CEA Timings #1: 1920 x 1080i @ 50Hz - 16:9 - '1080i25' says to be native, but the Detailed Timing Block 1 also claims to be native (Detailed Timing Block #1 - Timing definition: Mode = 720 x 576 @ 50,000Hz), quite small BTW. And the monitor description blocks lists two different timings (1920 x 540 @ 50,044Hz Interlaced and 720 x 480 @ 59,940Hz Non-Interlaced).

On top of that the Manual of the Sharp says the panel has 1366x768 pixels.

Can someone explain to me how this all works together and more importantly, which resolution I should choose? However, I tried 1366 x768 with SwitchResX with no success.

Any help would be greatly appreciated, since I am quite lost.

Dimitri

Here the EDID from the Sharp:
