Given the desired horizontal and vertical\nresolutions and refresh rate (in Hz), the parameters for a matching VESA GTF mode are printed\nout.   Two  output formats are supported: mode lines suitable for the Xorg xorg.conf(5) file,\nand mode parameters suitable for the Linux fbset(8) utility.\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS**\n- **DESCRIPTION**\n- **OPTIONS** (3 subsections)\n- **SEE ALSO**\n- **AUTHOR**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n"
