16K MegaHD

[Pyromania]

When will Amiga support 16K MegaHD monitors and televisions? It’s very frustrating not having this must have feature. This resolution is only 15360 × 8640. Come on guys what’s the delay?

Thank you, I needed this XD

Yet another thing the Amiga didn't get right from day 1.

Here ScreenMode shows max size = 16368 x 16368. So 32k would be a problem.

Well... vertical is not a problem - you can easily stretch video in vertical direction - probably beyond 8640 lines (at a cost of the vertical refresh rate) - issue of course will be horizontal line length... not sure if same trick can be applied to H length.

(apologies for trying to be serious)

I'd wager the required Chip Memory size for even a 1 bitplane screen might also be a 'small' problem, given you can't actually fit more than 4096x4096 pixels in it to begin with - if you have one of them new-fangled AGA machines, or a fully expanded ECS one.

Then again, perhaps you could use the Copper to reuse chip memory by rapidly shifting pointers around and fill in the required bits in memory with new data as you go along... So yeah, WHERE IS IT!?

We need it!

Only interlace mode is supported!

[Lord Aga]

Yes, we need 16K for our Python 6

[Pyromania]

64K UltraBadAss Monitor support would be even better!

Or we can do compressed bitplane and decompress this in HW... should be possible (alternatively treat FAST RAM as CHIP RAM trough some HW assisted shadow/bank window) - Copper could be used to control actual pointer...

I'm sure some of the newer RTG cards could support this resolution

The problem being that window, layer and cliprect coordinates are all 16 bit signed, thus "limiting" the screen size to 32768 pixels.

My eyes cannot even make out the difference between 4K and 8K resolution. Instead of more pixels, higher dynamic range would help. (-;

No worries - to easily determine 4k res you need at least 75' TV and for 8k over 100'.

btw ultra hi res is nothing insane but in fact quite right approach...
