The selectable resolutions on your computer depend on both the computer configuration and the resolutions supported by the monitor or display. Use the following suggestions to resolve your issue:
- Install the latest Intel® Graphics Driver
- Install the latest .INF file for your monitor
Check with your monitor manufacturer on availability of an updated .INF file or monitor driver.
- Install the latest system BIOS for your computer
Check with your computer manufacturer for the latest system BIOS and video BIOS with added support for the larger display mode. Or, check for instructions on how to update the system BIOS on your computer. Video BIOS can only be updated through a system BIOS update.
- Check your video cable connector
Your external display and your computer must have one of the following connector types: DVI, HDMI, VGA, or DisplayPort*. Extended Display Identification Data (EDID) does not pass through other connector types such as S-video, composite, RCA, component, or YPbPr.
- Check the supported resolution of your display if you are connected using VGA
Some displays only support lower resolutions (such as 1024x768) when connected using analog VGA. Check the user guide or user manual for the maximum resolution supported for each display connector. Some documentation lists the VGA connector as a D-sub input. Displays (especially TVs or HDTVs) can only support their large native resolution using a digital DVI, HDMI, or DisplayPort* connector.
- If set to Clone mode, switch to Extended Desktop mode
In Clone mode, the resolution defaults to the highest resolution supported by both displays. To set a separate resolution for each display, select Extended Desktop mode:
- Right-click on your Desktop and select Graphics Properties. Click Display, select Multiple Displays. Select Extended Desktop mode and click apply. You can now select the largest resolutions for each monitor.
- Windows XP users, verify that your monitor supports the resolution you want and deselect this Windows setting: Hide modes that this monitor cannot display
Deselecting this setting allows the display mode or resolution to be selectable if supported by the monitor. This setting cannot be selected in Windows 7 or 8.
Deselecting the setting Hide modes that this monitor cannot display and then selecting a display mode your monitor is unable to process can cause damage. We are not responsible for resulting damage from use of this setting. Verify with the monitor manufacturer that the monitor can support the display mode you want. Check with your computer manufacturer regarding the use of this setting. Some computer manufacturers do not support deselecting this setting.
- To change this setting, click Start, Control Panel, double-click Display, click Settings tab, Advanced button, and Monitor tab.
- If the display mode or resolution is still not selectable, click Start, Control Panel, Display, Settings, Advanced, Adapter, and List all modes. Then, select the desired display mode from the list and click OK.
Note If your monitor display becomes unreadable after selecting a display mode, recover by doing one of the following:
- Press the Esc key shortly after selecting the new display mode to undo the selection. Windows gives you about 15 seconds to decide on keeping the new monitor settings or reverting to the original settings.
- Power down the computer. Connect a different monitor or television and reboot.
- Power down the computer. Power on the computer and boot into Windows* Safe Mode by pressing F8 as Windows starts. Uninstall the Intel® Graphics Driver by removing the driver via Windows Add/Remove Programs Control Panel. Or, select the Windows Device Manager under the Display adapters section, reboot the computer, and let Windows start normally. Then, reinstall the Intel® Graphics Driver.
- If you are having trouble using the native resolution of a Digital Flat Panel display (1920x1080, 1680x1050, and 1440x900)
Use the Intel® Graphics Driver for the integrated graphics controller to specifically address this issue. Get this driver.
