Instead of a 2way splitter, you could try and clone your displays using the gfx driver <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> Matters are different with AVR though <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" />When I try and keep the HDMI signal alive for the AVR, which is connected through HDMI, then I see big problems.Turning off the AVR will remove the AVR from device manager, also I will lose the HDMI audio device as seen under control panel => sound. Applying the basic pin19 trick will keep HDMI alive, regardless of me turning on/off the AVR, this is until I resume from S3, then it wont re-detect it. which remindes me...about your splitter and detecting it's failure in re-detecting a HDMI connection.Try this:After you have just resumed and concluded that it hasn't connected to your splitter, then try and connect to htpc using teamviewer. Then enter device manager, click on your root entry, then select "scan for hardware changes".(the same can be done with a "devcon -rescan" on resume.)you can find devcon.exe on google <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> I use the tool hibernatetrigger to call a batch file containing this devcon cmdline onresume. It might do the trick. If "scan for hardware changes" works in device manager, then you would could take the step and use devcon. HDMI = something the devil invented !!! /gibman</blockquote>
