Hi, I have seen that there are multiple other threads out there with this complaint. Many of them are "solved" so I can't reply.
I want to add my voice to the annoyed chorus of those who want an option to disable the Acer / Energy Star spash screen while the monitor "boots"
I see Acer's official response is "there is no way to stop the boot process" (lame, since no other monitor I have ever encounters wastes users' time like this one with a multiple second delay showing logos every time it turns on) or "just run a screen saver" (even LAMER ... I'm not interested in wasting energy just to avoid Acer's decision to show an energy star logo every time I turn the thing on).
So, please pass on the feedback to your product team that this splash/logo/boot screen on Acer b243pwl has turned me off Acer monitors from here on. I do purchasing for our department, and although the Acer's price is better than the similar Dell model, we are going with the Dell. No one can fathom why Acer thought it was OK to take so long for a monitor to turn on and show the screen.
