I can't stand input lag. My current setup is a Vizio E series 40" (E400i-b2) and a Yamaha receiver (RX-V475). I used to have a nice Denon one, but it fried when I swapped an HDMI while everything was turned on. Anyway, I'm out of HDMIs and I'm wondering if I'd have more or less input lag using an HDMI switch and bringing the audio from the TV via SPDIF. I only use a 5.1 setup, so I don't expect to notice a difference in the audio. I just need to know if it'll cause me more or less input lag depending on the switch vs the receiver.
