This test directory contains some special test EDIDs: Three test files to check the edid-decode file parser: quantumdata.test: an EDID as generated by the QuantumData (nowadays Teledyne LeCroy) software. xorg.test: an EDID as logged by xorg in /var/log/Xorg.0.log. xrandr.test: an EDID as reported by 'xrandr --props'. Six hand-crafted EDIDs to test rarely seen EDID extensions or data blocks: cta-vesa.test: has VESA Display Transfer Characteristics Data Block and VESA Video Display Device Data Block in the CTA-861 block. ls-ext.test: has a Localized String Extension Block using UTF 8. ls-ext16.test: has a Localized String Extension Block using UTF 16BE. ls-ext32.test: has a Localized String Extension Block using UTF 32BE. blockmap-128.test: has a single Block Map extension and a total of 128 blocks. blockmap-255.test: has two Block Map extensions and a total of 255 blocks (the maximum possible EDID size when the second Block Map is used). 256-blocks.test: has the maximum number of 256 blocks. cta-timings.test: contains various DisplayID and OVT timings in the CTA Extension Block. cta-vfpdb.test: use to test correct VFPDB parsing. This EDID has a 1080p60 DTD 1 in Block 0, and a 1280p60 DTD 2 and 2560x1440p60 DTD 3 in Block 3. The Video Format Preference Data Block says DTD 2. If the display driver selects 1080p60, then the driver does not support the VFPDB. If it selects 1280p60, then it supports the VFPDB correctly. If it selects 2560x1440p60, then it supports the VFPDB incorrectly, ignoring DTDs in Block 0. cta-eeodb.test: contains an HDMI Forum EDID Extension Override Data Block Examples of old EDID versions: edid-1.X.test: EDIDs with version 1.0, 1.1 and 1.2. Test EDIDs from several standards: cta-annex-a.test cta-annex-d.test vesa-edid-1.1.test vesa-edid-1.3.test vesa-edid-1.4-1.test vesa-edid-1.4-2.test vesa-edid-1.4-3.test
