No. I have a Sony G520 CRT monitor with a hardware switch. When I flip the switch, the other image appears in less than a second. In the past I had a Samsung (I don't remember the model) that made the switch without even interrupting the electron beam, in mid-frame. First 2 frames were garbage, until it sync'd to the new signal, but it only took a blink of an eye to switch (at 85 Hz). It was also very quick to sync after a mode change. I could see BIOS screens that modern flat displays are to slow to display before they dissapear.
