+===== dummy hdmi ====
+has circuitry to store and transmit EDID (Extended Display Identification Data) emulation information to the GPU. by using an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip programmed with the EDID data of a typical monitor. a.k.a hdmi emulator plug
+there are such dummys that have a passthru female socket. i have not find a nice one yet
 ===== generic HDMI splitter 1x2 =====
 i got the following in my weekly meeting with [[https://www.aliexpress.com/item/1005005972745533.html|aliexpress packges]] at the mailroom.
 === MS9332 IC ====
-The MS9332 is a one-to-two active splitter that supports a signaling rate up to 3.0Gbps. With 3.0Gbps capability, the MS9332 can support the new 4K@30Hz video format. The MS9332 equalizes incoming TMDS data with optimal quality regardless of the incoming signal quality. The highly acclaimed equalization technology provides for support of long or low-quality HDMI cables at even the highest speeds. Input terminations of the TMDS inputs and output current levels are both programmable. The chip also supports on-chip HDCP Keys RAM and EDID Memory.
