On my nspire, in the maintenance menu, there is a screen contrast option that has a much wider range than in the OS, and when turend all the way up, turns the screen blue, without the rapid flipping.

When removing the Nspire keypads while running an ASM/C game (I think it happens when a 84+ game crashed in 84+ mode too), a blue line appears in the screen for a short while.

Nice.  This would be a very cool effect for a final boss battle. ;D

I wonder if there is a way to do this without risk of screen damage?

Woah.  This is very cool.
Alarming at first (from looking at the first video), but if you can control it so you can get actual bluescale, like in the second vid, then this could be really awesome!

Source code please?  (or did I miss it?)

ok, here's the source for my video

Code: [Select]
:.A
:DiagnosticOff
:ClrDraw
:Rect(63,0,32,64
:Repeat getkey(15)
:RectI(31,0,32,64
:Dispgraph
:Shade(0
:Pause 4
:Shade(63
:End
i doubt this will be of much practical use, though, and you use it at your own risk. furthermore, it should only work on the 84 lcd's

EDIT: changing the pause length also changes quality, flashiness, etc, so test out different times to see what you get! so far 4 seems the best(with this particular code) when running in 6mhz mode. the optimal time varies if you add in different draw functions, movement code, other stuff

I noticed that it does not appear very blue at first, and you have to leave it running for a little bit to get it to fade to a blue-ish color.

That's actually a pretty cool piece of code. If someone could get white to show up with the blue and black, I would definitely consider using this for something...

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

That looks really cool guys :) Is there any way to test to see what does damage and what doesn't? I mean I know Quigibo (I think) did that test a while ago on how to achieve the blue screen. This could be really sweet though if we can utilize this some how without damage :D Great job guys!

does this work on the 83+? if so, is it safe to run?

Nope it will not work on a 83+ nor a Nspire. Also I forgot shade does contrast x.x.

At certain values it's pretty cool but try to not let this run for extremly long.

i actually managed to get a few white blocks to show up, but it was not intentional(and i doubt i could do it intentionally). this blue stuff only works predictably for vertical lines, meaning it's not really worth the effort XD.

EDIT: also, i just realised that i've started calling real life photos screenshots

Reminds me of that Screentest command in Assembly. You know, the one that destroys the LCD by applying full power to all of the pixels :P
