Is hdmi broken in xbox 360?

Lately when playing any game on the 360 via hdmi i have noticed that the picture quality has been degraded. Specifically when playing GTA IV I notice that the picture is not as sharp and there is also a really bad ghosting effect where if u look at the sky at night and there are light post nearby when you move the camera the light post smudges the screen a really bad ghosting effect. This effect is found everywhere in the game when played via HDMI thus degrading the picture quality .I have tried every setting on the Xbox 360 but it hasnt helped. This is completely gone when playing via component where the picture is sharper, has more colour, and has no ghosting effect at all. Has anyone else encountered the same problem with hdmi?

Usually if that happens, it means your cable has problems and you should get a better cable. I am pretty sure nothing is wrong with your connection port on xbox 360 or tv

first time Im hearing a problem like that with the hdmi, sorry to hear that man, maybe u should try playing using the component cable instead I still use that up to this day no problems, the only problem I had really was my xbox being overheated yea I pretty much got the red rings :(
