it is a problem with the technology, somethings you can do too reduce it, calibration.. lower the contrast &/or brightness, turn off auto contrast on the tv, turn on the power saver mode, lastly is adding a low watt 6500k light behind the TV (ambient lighting).
Has nothing to do with the cable, it is the TV it self, ghosting is found on all LCD brands & models, in any price range... I do not know if ghosting is found LED LCD's
If it really really bugs you, look at getting a plasma or DLP RP
I have a 32" Samsung LCD TV, I have had it for about a year now. It has always been connected using component cables, I decided to upgrade to using a HDMI cable. Because of my set up I need 15 ft of cable to connect the TV to the HD PVR cable box.
From my research on google I believe what I am seeing is called Image Persistence. It is not always there though, it only happens when a frame goes to black. For example it happens when a commercial ends and goes to black to got to the next commercial. That second of black you can still see what was on the frame before its just looks ghosted. I can view the exact same thing with the component cables connected and you I do not see anything but nice crisp black, no ghosting.
Does anyone have any suggestions on what it could possibly be? TV maybe?, PVR box? as for the HDMI cable I have tried another HDMI cable, this one was a 6 ft. cable and it does the same thing (ghosting). Both where purchased form the same spot though (www.monoprice.com).
Any help in getting to the bottom of this would be greatly appreciated. Thank you.
