I'm using two 21" CRT displays, one connected to my notebook's dock's VGA, second to DVI using DVI-HDMI converter and HDMI-VGA converter. Then only VGA-Sun cable is connected to monitor. In my case, having such "adapter ladder" makes system forget about monitor's default modes, obtained in Linux by VESA digital signals. To fix the problem, I have a shell script which starts when my laptop is docked or starts docked. This script consists of xrandr commands, like: - Turn off notebook's internal display - Turn VGA monitor on - Insert modeline to DVI. - Turn on DVI, right of VGA. - Select resolution from inserted modeline. Personally I couldn't fix the problem in any GUI solution, or without modelines. MCbx

I have a box with Debian Wheezy and TDE installed in it. The GPU has three connectors, one DVI and two HDMI.
I have two monitors connected to it. The diagonal measurement of one is 49 cm. It has a 1600x900 resolution and is connected to the box by a DVI cable.
The other is a TV/monitor with a diagonal measurement of 124 cm (49 inches). It is connected to the box by HDMI. The box recognizes its existence, but the display on it has the same resolution as the smaller monitor.
It consequently uses only about 40-45% of the screen area, nor is it centred on the screen. It starts more or less from the upper left corner and leaves an L shaped unused black space on the bottom and right sides. The left side does not correspond to the left side of the screen; a strip on the left side of the display is seen on the smaller monitor but not on the large one.
Is it possible to create a display resolution larger than 1600x900 for the large monitor and properly centred on the screen, possibly using the ‘Monitor and Display’ feature of the TDE Control Centre?
Regards, Ken
