Archiv verlassen und diese Seite im Standarddesign anzeigen : Intel - Höhere Auflösung von Laptop-Graka auf externem Monitor erzielen

2007-08-20, 13:31:28

ich benutze momentan einen Acer TravelMate 243LM.
Installiert habe ich dort Win XP & Treiber von der beim Kauf beigelegten CD. Laut Systemsteuerung ist ein "Intel(R) 82852/82855 Graphics GM/GME Controller" mit 64MB verbaut.

Zu Hause ist der Laptop an einen normalen 17" Röhrenmonitor angeschlossen.
Mein Problem:
ich schaffe es nicht eine höhere Auflösung als 1024*768 auf dem externen Monitor zu erzielen mit dem Laptop. Ich vermute das liegt an der Grafikkarte (der Monitor lief früher schon auf höheren Auflösungen an einem herkömmlichen Desktop PC)? Kann man da irgendwas machen mit neuen Treibern, Tools o.ä.?!?

Schonmal ein Danke für eure Bemühungen!

Topic ist natürlich falsch, es handelt sich, wie geschildert, um einen externen Monitor!

Hast du mal den Treiber für den Monitor geladen falls es kein plug and play monitor ist?

Oder vielleicht hilft das, aus dem FAQ von Intel:

Q: Why can’t I select a larger display mode (resolution, refresh rate, or colors setting)?
A: Your specific computer and/or monitor may not support the full range of display modes (resolutions, refresh rates, or color settings) that are supported by the Intel® integrated graphics chipset and drivers. The Windows* operating system will prune out or exclude (by default) display modes that are not supported by both the graphics controller and the monitor. If you are unable to select the desired display mode, please try each of the following suggestions:

1. Install the latest Intel® Graphics Driver.

2. Install the latest INF for your monitor. Check with your monitor manufacturer to see whether an INF update is available for download.

3. Install the latest System BIOS for your computer model. The latest System BIOS may contain a newer Video BIOS update which may add support for the larger display mode. Contact your computer manufacturer to check whether a newer System BIOS is available for download. A Video BIOS cannot be updated by itself, but must be done via a System BIOS update.

4. If you are using an external display such as an LCD panel, check your video cable connection. Your display device must have one of the following connector types: DVI, HDMI, or VGA; and your computer must be connected to one of these connector types. EDID information is not passed through an S-video, composite, or component (YPbPr) connection.

5. If set to Intel® Dual Display Clone mode, switch to Single Display mode. You may not be seeing the monitor's full list of supported display modes if set to Intel Dual Display Clone mode (one of the Multiple Display modes). In Dual Display Clone mode, the available display modes will be reduced to only those display modes that are supported by both monitors.

An Example: Suppose you have a laptop that contains the Mobile Intel® 945GM Express Chipset and has two displays: the internal flat panel display (also referred to as Local Flat Panel or LFP) and an external widescreen flat panel monitor that is connected to the laptop's VGA connector. If the laptop's LFP only supports 800x600@60Hz and 1024x768@60Hz and the external flat panel monitor only supports 800x600@60Hz, 1024x768@60Hz, 1152x864@60Hz, and 1440x900@60Hz, then the only display modes available in Dual Display Clone mode will be 800x600@60Hz and 1024x768@60Hz.

To switch to Single Display mode, follow these steps:
1. Open the Intel Graphics Drivers Properties window using just one of the following methods:
* Press the Ctrl+Alt+F12 keys.
* Right-click on the Windows* desktop and select Graphics Properties.
* Click Start » Control Panel, switch to Classic View, and double-click on the Intel(R) GMA Driver entry.
* Right-click on the Windows* desktop and select Properties to open the Display Properties window, select the Settings tab, click on the Advanced button, select the Intel(R) Graphics Media Accelerator Driver tab, and click on the Graphics Properties button.
2. On the Display Devices tab, under Single Display section, click to select the appropriate monitor or digital display.
3. Click to view the Display Settings tab.
4. The monitor or display's supported video modes (resolutions) should be selectable on this tab.
5. After selecting the desired display settings, click OK or Apply.

6. If you have verified with the monitor manufacturer that the monitor does support the mode or resolution you desire, disabling the Windows* “Hide modes that this monitor cannot display” checkbox may allow the desired mode or resolution to become selectable.

CAUTION: Clearing the “Hide modes that this monitor cannot display” checkbox and then selecting a display mode your monitor is unable to handle may cause damage to your monitor and/or cause the monitor display to become unreadable. Intel is not responsible for damage resulting from use of this setting. Be sure to verify with the monitor manufacturer that the display mode you desire is supported by the monitor. It is also recommended to check with your computer manufacturer regarding the use of this checkbox. Some computer manufacturers do not support the clearing of this checkbox.

This Windows checkbox is located at Start » Control Panel » Display » Settings » Advanced » Monitor tab. Afterwards, if the desired mode or resolution is still not selectable, go to Start » Control Panel » Display » Settings » Advanced » Adapter » List all modes button, select the desired mode from the list that appears and then click OK.

Note: If your monitor display becomes unreadable after selecting a display mode, you may be able to recover by doing one of the following:
* Press the Esc key shortly after selecting the new display mode to undo the selection. Windows may give you about 15 seconds to choose whether to keep the new monitor settings or allow you to revert to the original settings.

* Power down the computer. Connect a different monitor or television. Then, boot up the computer.

* Power down the computer. Power on the computer and boot into Windows* Safe Mode by pressing F8 while Windows begins to start. Uninstall the Intel® graphics driver by removing the driver via Windows* Add/Remove Programs control panel or by uninstalling the driver via Windows* Device Manager under the Display adapters section. Reboot the computer and let Windows start normally. Then, re-install the Intel graphics driver.

7. If the above suggestions do not help, please contact your computer manufacturer for more information and further assistance. Your specific computer configuration may not support the maximum display modes or resolutions supported by the Intel integrated graphics and/or may be customized by your manufacturer to exclude certain display modes or resolutions from being available.
