Most gamers prefer 1920x1080 144hz over hdmi or display port these days. Can snicker doodle black handle such resolution while inserting an overlay?
No but maybe Yes.
No, as 1920x1080 144Hz is a 357MHz pixel clock rate which is above the TDA19988 HDMI transceiver capability on the piSmasher HDMI in/out baseboard.
Yes, as with a different (read: more expensive) transceiver would be able to do that. You'd likely need an HDMI transceiver with LVDS I/O designed for 4K video.
Generally available HDMI framers/transceivers with pixel clock rates above 297MHz are a bit more rare at the moment but some are starting to come to market.
Most often, at those levels due to signal integrity challenges multi-gigabit transceivers directly built into the FPGA/GPU/CPU are being used to produce the signalling for HDMI and DisplayPort (along with expensive IP in the case of HDMI).
