I definitely understand your concern regarding your external display not going to sleep and endlessly looping into power save mode when your MacBook Air is asleep.
I found an article with steps to troubleshoot issues with displays. This article is for internal and external displays, so you can skip any steps referring to the internal display. The following steps specifically stands out to me for the situation you are experiencing:
Reset the system

Didnt help at all... still does the same old stuff. I'm going to at least try a DVI-D adapter... i know it shouldnt matter, but I'm going to see if this is HDMI related. This really ***** though. Why in the world wouldn't this work? Apple HDMI adapter.... heck, they make it just for non-Apple displays right?
Hoping to resolve this... so far, it's just a headache.
Thanks for helpful ideas though... keep em coming.

I even bought the Belkin adapter (w/HDMI cable) that they sell at the Apple store... still doesn't work. Glad I can return all this stuff. Should have an DVI-D cable tomorrow.

I was thinking about the issue you are experiencing with your display, and I was wondering if your display and computer sleep settings were the same in System Preferences>Energy Saver. I recommend setting these to the same time if they are not and see if the issue persists.
If you need assistance with this, you can find the steps under the section titled "Change your Mac's sleep settings" in the following article:
If the computer and display sleep both have the same settings, you may find more information by using another one of Apple's support resources - https://expresslane.apple.com/GetproductgroupList.action

Well, it wasn't the display, or the MacBook Air... it's the HDMI usage. I went thru 3 (maybe 4) different combinations using the Apple mini displayport to HDMI adapter + HDMI cable, Belkin mini displayport to HDMI adapter + Belkin HDMI cable (Apple sells from store), mini displayport to HDMI cable and nothing worked.
Bought this (http://www.amazon.com/gp/product/B004CAHTCQ/ref=oh_details_o00_s00_i00?ie=UTF8&p sc=1) off-brand mini displayport to DVI cable for $11 (not really a fan of all these adapters + cable) and it works PERFECTLY.
Not sure what the issue is with the Apple thunderbolt/mini displayport to HDMI solutions, but it sure wouldn't work.
Thanks to all for the help/feedback. Apple really should figure this out... lame that the original Apple supported solution didn't work. Oh well.
