Overscan

[CubeTheory]

Probably some stupid questions, but here goes:

I've just moved my A500 off of a 23" LCD 1080 tv with enforced overscan to a dell 1080 monitor with no overscan, connected via a scart to hdmi adapter. both monitor and tv were set to 4:3

i had never really noticed it before but its painfully obvious now how everything is shifted off to the right. booting into wb3.1 on my ACA500Plus i get a huge border around workbench and as i say its offset to the right.

I can fix this by altering the overscan settings in prefs and make it fill the entire space which is nice and everything is central, and i get loads of real-estate, but running games in WHDLoad, they are offset again. booting into a game is the same.

First question is, why is the A500 like this by default? its the same on WB1.3 and although i can centralise the pic on wb1.3 i cant adjust the overscan (i dont think).

Second, although i can fix this in wb3.1, is there anyway to transfer these settings to other bootable disks? i dont know where the overscan settings are stored, to be honest.

EDIT

This is the default


this is with overscan correction


thanks

Brill! thanks!

hey, another Scouser! pleased to meet you

Best to learn to live with the fact that the Amiga's display is like this. :-)

If you start a game or demo, it will not respect your overscan prefs, but at least you will be able to see all of it, no matter where the coder decided to locate the screen at.

Yeah using the standard 320x256 values in the hardware reference manual you get offset to the right by about 12px - always used to bug me. You can use different values (which is what the overscan prefs will do) but you start losing sprites and using extra DMA - so most games/demos will use the defaults.

Ah, thanks. It never bothered me until i switched to a monitor, now its so obvious. looks great in WB though with the overscan settings going right to the edges.

One thing i was curious about though is you dont see the same effect in UAE.

UAE defaults don't show the entire overscan area. I'm guessing Toni decided he doesn't want to be contacted about this aspect of the Amiga display hardware. :-)

Thankfully UAE can be easily configured to display the entire overscan area, just like Jay Miner intended. ;-)
