The Intel graphics driver does not detect the native resolution of 1360×768 on many of the earlier “HD Ready” Samsung TVs, should you connect your laptop or PC via the VGA cable. But this resolution is possible to configure giving a very clear pixel per pixel display, even via the analog VGA cable. Strangely the HDMI connector will not give 768p resolution, only 720p max, so the VGA cable is your better option for these TVs to get the maximum resolution without any black bars or doubled lines due to scaling.
To get the resolution do the following:
- Download the DTD Calculator from Clever Technologies here. This will allow you to enter a custom resolution and save it into the Intel driver’s registry entries via the “registry hack” feature.
- Run the tool, make sure to “Run As Administrator” on Visa and Windows 7 with UAC turned on (that’s the default in case you don’t know what it is or if you turned it off).
- Below are the “modeline” (also known as “EDID” display ID) settings for the Samsung HD Ready TVs. This is what you enter into the DTD Calculator program along the left side top-to-bottom.
- Pixel Clock (MHz) 85.5
- H Active Pixels: 1360
- H Start of Sync Pulse: 1424
- H End of Sync Pulse: 1536
- H End of Blanking Interval: 1792
- V Active Pixels: 768
- V Start of Sync Pulse: 771
- V End of Sync Pulse: 777
- V End of Blanking Interval: 795
- Interlaced: No (Clear Checkbox)
- Sync Profile: +Hsync +Vsync
To find modelines for other displays, go to places like the MythTV “Modeline Database” Wiki. Alternatively you use tools to read the EDID (VGA plug-and-play display information standard) directly from your monitor, such as the free version of the Monitor Asset Manager (also known as MonInfo) program from EnTech Taiwan.
