I tried that a few years ago to send a HDMI signal to two outputs. The results were not that good. This goes basically to a lot of threads I have seen on the topics. However, it appears, since about two years, some have had great succes doing so. Anyone has tried that before and which devices would you recommend?

Basically, a laptop has a HDMI output. So, the laptop has its own screen. Then, a 27-inch monitor is the second one. That is the current setup. On top of that, we need to send the output to a 42-inch monitor.

The result has to be as is, nothing less. Any interruption or random interruptions won't do, timeout issues or anything like that. Suggestions?
