On my old and small tv:
- I see only about 336 pixels in width and the screen is shifted one character to the right
- I see only about 256(?) pixels in height - starting from the 16th line (from a 288 line screen)

Is this normal or is it just my tv?

That would mean that ep has considerably bigger pixels than the c64 (on the ep I have no place for the c64's side borders), I guess...

Thanks for the links.

I wonder what is the reason for such "magnified" and shifted display...
Well the TV was broken many times before...

However I remember reading in the nick doc:

"10. Vsync Mode - Vertical Synchronisation
[...]
These LPBs make a total of 25 lines, leaving 287 lines left for the display. In practice, because of overscanning, it is not possible to use more than about 256 of these for display, the rest must provide top and bottom borders. "

So is there a problem with displaying screens of vertical resolutions bigger than 256 or there's nothing to worry about?

Generally we can say (I think) that every monitor and TV sould display the size of the 320 X 240 (with HIRES 4 size of pixels) WITH some border ...

It is basically for example the IS-BASIC screen.

If your TV cuts the BASIC screen or there is no border around it,
then your TV shows too less, far less than generally.

You can set the border on the BASIC screen like:

set border 255

Vertically it would be around 240 lines so I guess the TV satisfies the general criteria.

In this case ... Yes.

But (of course) the wider is the better ...

There are screens of tools and demos (maybe games aren't but only one or two) and such using larger screens.

For example now I write a thing, using 368 X 272, and I would not like to be smaller,
because I use LORES 4 and doubled vertical scanlines,
so the effective resolution of my game will be as little as 184 X 136 ... at the same physical size on the display.

So if I were decreese the size of the screen, my resolution would be even smaller ...
So the screen stays the biggest possible what displays usually shows ...
And that is the 368 X 272 (with the standard pixel size, again) ...

It is bigger than the "must display" size, but the "not limited" displays usually display this big screens ...

Above this, there are a few TVs what show the screen without cutting ...



The EXOS doc says about NICK:

http://gafz.enterpriseforever.com/Dokumentacio/Konyvek/EXOS_2.1_technikal_information/hardware/Nick.html

"allowing up to 42 characters per line", what is 42* 8= 336 (HIRES 4 pixel) wide ...


What is far below the 368 I use in my game ... Maybe we just found the reason why my game does not run on the real steel ... ?!

These are not unusual on a TV, although the screen is more commonly shifted to the left by one character.

Ugh:oops: ... It's "shifted to the left"....
I'm almost 30 and still have problems distinguishing right from left.. .

EP pixels are closer to square shape (in 4-color PIXEL mode), on the C64 they are narrower.

Maybe was this because of the quality of the CRTs from that age ?
I noticed on all of my CRTs, that pixels are wider than their height (in HIRES 4, too) ... Maybe the C64's pixels arent as wider, because of this trick ?

running my game wip

Can I see a screenshot somewhere about it ? (Beacuse of the game, not because of the pixel width ... )
