I am curious about HDMI inputs (especially on HDMI 2.0 and later inputs with 4K support) which have an EDID with more than one 128-byte extension page.
On an Onkyo TX-NR509 AV receiver, all of the HDMI inputs have an EDID Extension Pointer at 0x60h (I2C Address Scan with a Bus Pirate) and all only have one 128-byte EDID Extension; on a Samsung PS59D8000 (Series 8+) TV, all of the HDMI inputs have only one 128-byte EDID Extension and all do not have the EDID Extension Pointer (0x60h does not show up on an I2C Address Scan with a Bus Pirate).
There is a good chance that there would be EDID problems (at 0xA0/0xA1) with inputs having more than one 128-byte EDID Extension without an EDID Extension Pointer (again, at 0x60h); an I2C memory device =<256 bytes requires only one address byte, but there would be problems (and certainly the danger of corrupting its contents) in accessing an I2C memory device requiring two address bytes (I2C memory devices >256 bytes but =<64KB) like a device requiring only one address byte.
Do you know of any TV/display devices with HDMI input(s) having an EDID with more than one 128-byte Extension page?
Beware, the EDID on each HDMI input (on the same TV/display device) can be different as each HDMI input can have different capabilities.
