I had the same problem and when I read this thread, it dawned on me that I had not thought of there being an "Input Select" option in the monitor settings. Sure enough, that was all my problem was. Now, having my HP laptop connected to my ASUS monitor via HDMI works fine. I had just thought the monitor would work if you had a good connection to a source, but then again, I should have thought about how the monitor would handle it if you had more than one source connected simultaneously, like VGA and HDMI at the same time. In that case, it makes sense that the monitor would have to ask you what source you wanted to use or there would be a "Input Select" option to tell it what source/connection to use.
Another thing to note, when I changed the monitor input selection to HDMI, I had no audio/sound then. I figured the audio was being then sent thru the HDMI cable, but because my monitor doesn't have speakers (I didn't want a monitor with speakers... would rather have decent separate speakers) I wasn't getting any sound. Sure enough, that was it. Once I had opened my audio settings and set "Speakers and Headphones" as the default place/ports to send audio to, my audio/sound was back as usual.
