I have a new laptop and I've connected it to a HDMI-splitter because I want to mirror the laptop screen on to two separate tv's. Both are connected through 15 m HDMI-Cables but goes together in a splitter because the laptop only has one HDMI.
When connecting only one of the two screens directly to the laptop HDMI, no problems. And I didn't have any problems until a few Days ago. So for a week or two it was perfect.
It is only the laptop screen that's flashing. Pretty slowly. About one time/a few seconds apart.
Seems like it has something to do with the splitter maybe.
Tried to update the Graphics card, but there was nothing to update. Tried to bring down screen resolution AND Hz to 50 but no results.
I am not sending anything demanding through the Cables, only mirroring the desktop and showing an excel-file (work Schedule).
Does anyone have an answer?

By flashing what do you mean? It might be that the cable might have a damgadeg spot, which interupts the connection for just enough time that the laptop thinks that the cable was unplugged. – Mario Stoilov – 2014-03-21T08:52:50.490
15 meter HDMI cables? Theoretically that should be OK (e.g. http://www.avsforum.com/t/783852/max-length-for-hdmi) but can you try with shorter cables? And please edit your question because it is not clear in what configuration you have problems and in what configuration you don't. Also, it's irrelevant what screen data you send over the wire, only resolution and frame rates count.
