Turning on a fluorescent lamp in my girlfriend's kitchen used to make her TV cut out. It turned out it was the HDMI signal rather than the TV - presumably the EM pulse was enough to disturb the HDMI signals for long enough that the picture couldn't be decoded.
An electro-static discharge is effectively a broad band RF transmission (see spark gap transmitters) - so it's not surprising that it would interfere with a sensitive high bandwidth communication link. It's more surprising that the monitor would go into standby or restart, rather than just losing sync on the HDMI signal.
