What you might want to try is to access your TV's service menu. This is what I had to do way back when.
Basically, a service menu is where you can adjust all kinds of settings for your TV. It's possible to mess your TV up completely if you just randomly change values. A good precaution is to write all the default values down after first accessing it.
As for actually accessing it, that might be a bit tricky. Unless your TV happens to have an easy access to the service menu via a dedicated button (unlikely), it's accessed by inputting a code on your remote control. Something like 062595 and [Menu] button. Try searching Google for your TV's make/model and "service menu" or "service mode".
In my TV, the settings I needed to change were under "Geometry"-heading. There were a bit cryptical titles for the values such as VAM, HSH, SBL, H60, V60...the important ones were H60 and V60 which control the Horizontal and Vertical area when the TV is in 60hz mode. I just changed the values one by one while keeping a shmup running in the background until the game was displayed correctly. This doesn't, however, mean that all games will be displayed exactly the same way (ESPGaluda still crops a little at the top), but you can find a good middle-ground that works for all.
The procedure's not that difficult to do, you just need to be careful doing it.
