[QUOTE="_Micha_, post: 975588, member: 138466"] Hi [B]gibman[/B], I tried it but in a different way because I do not have the mentioned HDMI-adapter. My idea was to modify my HDMI-splitter (Ligawo® HDMI Splitter: 1 HDMI-in -> 2 HDMI-out, its price is around 20 EUR). This splitter was in use by me over 3 years, no problem. Then I bought a new NVDIA-ION based motherboard and since then this was (and unfortunatelly is) my problem: [I]After recovering from windows energy saving state (in my case S3) the splitter is only detected by Win7 if I restart windows or if I unplug the HDMI cable and plug it in again.[/I] (I do not use HDMI-audio.) The proposed solution (apply 5V with an pull-up resistor to pin 19 = Hot-plug detection) was from my point of view a good approach. I have NOT cutted the connection to the PCB but simply applied the 5V to pin 19 because if it is realy only looking for this voltage level then a pull up should work without cutting the PCB connection. After my modification I measured that there is the expected voltage and then tried it out: Nothing changed. Only the two above mentioned ways bring it back :(. I would now expect, that the [B]static[/B] [B]5V[/B] is the problem (with the rising / falling edge of a appearing / disappearing 5V it may work ?!). May be I will order the proposed HDMI-adapter to try exactly the solution but I don't know if it is worth to continue. Greetings! Micha P.S.
