This is a long way of getting to the last paragraph. If you're inpatient, just skip to it.
I had an interesting situation a couple days ago that may have led me to the resolution of the overscan problem with HDMI input. I never had that problem, but many other people have reported it. I ended up solving a temporary overscan problem I had with VGA.
A couple days ago my son told me the set wouldn't tune any channels. It kept saying it was on channel 65535. Being a computer person, I recognized that number as something going wacky, probably in memory somewhere. It didn't clear after unplugging the set, and when plugging it back in, it immediately turned on and went to channel 65535. I did get it to tune down to something like 182.5 (with no picture or sound), but it stayed stuck there. I couldn't get into the service menu, adjust volume, turn it off, or anything.
After trying unplugging and plugging a couple times, I was able to catch it just before it displayed the channel and locked up, and changed the input source. I was able to go back to TV and get a look at the channel list and each entry had "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿÿÿ" as its name.
Eventually I was able to get into the regular menu to retune the channels, and they worked again, but each time I changed channels there was a residual "ÿÿÿÿÿÿ" that showed on the screen while the channel number displayed. So I figured I'd try to reset the TV.
I went into the service menu, into Other Settings, and did the EEPRom Init. Then, after retuning the channels, the "ÿÿÿÿÿÿ" was gone. So far so good, and I'm only recounting this in case this happens to anyone else.
Of course all my previous changes in the service menu were back to factory settings so I went in and made a few adjustments. I accidently changed a few while looking through all the settings and set them back to what they were (I thought). Later that day I was using my HTPC on the TV and VGA didn't look as good as it had anymore.
I recently built a new HTPC to use with the Dynex, and for some strange reason HDMI wouldn't display. Only VGA would. I use HDMI with a DVD player and have used it with other video cards on that HTPC and another one, but the built-in video chip on the new HTPC won't work with the Dynex's HDMI. But surprisingly, VGA is so good that I really can't tell the difference. I was amazed to find VGA being so good, as I generally can't stand VGA on a monitor larger than 17". But it really looks 1:1 pixel mapped just as HDMI does on the TV. Dots on "i"s are perfect, there's no blurring to adjacent pixels on anything.
But after resetting the EEPROM back to factory settings and probably messing up some setting as I was scrolling through all the other settings, the VGA ended up with overscan and was definitely not 1:1 pixel mapped anymore. Desktop characters were fuzzy and not very pleasant to try to read. So I initialized the EEPROM again and VGA went back to no overscan and perfect 1:1 pixel mapping.
I figured this long story might help people who were having trouble with their HDMI having overscan. Mine never did, but many other people reported problems with it. If you have that problem maybe try resetting the EEPROM and see what happens.
