I have exactly the same problem:
Laptop: MacBook Pro 13", Mid 2012
External Monitor: Samsung SyncMaster SA550 (HDMI input)
Mini DisplayPort to HDMI Adapter: Moshi Mini DP to HDMI Adapter with Audio Support (H1824ZM in the Apple Store)
Colors are generally washed out, very low contrast, very high brightness, some fonts are distorted.

Nice to know that I'm not the only one.

This might be the reason... https://discussions.apple.com/message/18789011#18789011
I was pulling my hair out until I found that. I never knew that Control-Option-Command-Period had that function!

I called Apple, they had me reset the PRAM, but it didnt help at all.
They are having me bring it into a store to have it looked at, they believe that it may be a manufacturing problem, especially when many people are having the same issue.

Interestingly enough, I tried it on a really old 720p tv and it worked fine. I wonder if the hd4000 isnt calibrated to output 1080 well....

Same here. Checked with my Samsung Syncmaster 27" and an older Philipps 37" TV.
Color, fonts, nearly everything looks like crap on external devices.
However I'm using this adapter http://www.amazon.de/gp/product/B003ORJOX0/ref=oh_details_o01_s00_i00 and this one might cause the trouble, I don't know. I'll try to check another adapter and another cable and will report back then.

MBA 13" i7. Moshi HDMI adapter.
Samsung syncmaster t240 (24"). Colors are horrible. Tried calibrating with the expert mode. It feels almost as before, expect some colors and specific places comes off realy bad. Like the casted shadows from a window to another if terribly rendered.
You are not alone !

Same here: mid-2012 MBA 120G/8G RAM
WhenI connect my Air to external BenQ 24" HD screen [GL2440 HD] with Apple HDMI cable - picture quality is poor (being kind here) but when connected using DVI cable, picture is crisp - NO comparison in picture quality - HDMI image quality ex Air is garbage. Text is soft/fuzzy and colours washed out, colour profiles make minimal to nil difference to picture quality. Swapped to DVI cable and image is HD crisp and colours spot on.
Firmware issue re HDMI calibration perhaps?
