Display problems - Black lines on screen

[FLiebe]

1st at all ... Hello everybody this is mi first post here. I´am a new retro-player user.

 

in last 2 months I made a full restauration of my 2600, 130Xe and 1050, buy a Harmony Cartdridge , a Fujinet interface , 1050toPc cable and Sdrive Max.

 

A lot of updates!!

 

I have a problem to solve , when connect the 2600 to the proyector , the menus of Harmony displays only 50% of lines , one is present and the next is black.

 

After load a ROM the picture is 100% present.

 

Any idea about whats happends ?

That's your projector, which cannot handle interleaved graphics well. You should experiment with the projector's settings.

Exist some 2x scaler then can handle  interleaved graphics well? 

 

I read some post and find due a "timming isues" some games perform good and other not ... but al least y want have a correct display of Harmony menú in my LCD :-)

It is not the "timing", it is just that the graphics mode of the 2600 is frequently not supported well by modern hardware. And that leads to missing lines.

 

A scaler might help, but you should check if the input and output it uses and creates fits to the 2600 and your projector.
