Overall, this HDMI splitter works decently well, and will probably work very well for most people.My specific use case is splitting a signal from my desktop PC to a monitor as well as a capture card feeding into my laptop. The monitor runs at a higher resolution and refresh rate than the capture card, which maxes out at 1080p60.When using this splitter in “A” mode, it provides the right resolution to the capture card but misidentifies the monitor’s specs and either makes everything tiny because it thinks the monitor is higher resolution than it actually is, or makes everything look fuzzy when set at the correct resolution manually. I tested both HDMI outputs on the splitter in case it was expecting the highest resolution device to be plugged into specifically the 1st or 2nd output, but it didn’t help.So I was forced to use the “B” mode, which allowed everything to work and look good, but now the monitor was capped to 1080p60, since that was the max for the capture card. It could be something about the capture card I’m using that prevented the “A” mode from working as intended, or it could be a limitation of this splitter, so I’m only docking 1 star to be fair.
