Aligned vs Staggered Screens
« on: March 12, 2020, 12:53:52 pm »
Hi all!

Well, I finally found out why I could NOT have pixel-perfect scaling in my RG300 which, incidentally, got returned because of dead pixels. It's like a digital camera screen, with alternating pixel columns, and for pixel-perfect scaling we need aligned pixels...



I actually found out when taking pictures to get it refunded, so dead pixels came in handy for once!

But I liked the RG300. My only issue (dead pixels apart) was the fuzzy scaling I got with GBA games, for which 480x320 should be perfect. Cave Story looks beautiful at 480x320, even with  those stupid-non-aligned pixels. So now I'm wondering... Are there other handhelds with this resolution out there? Are there compatible screens which have aligned pixels?

I know the Sony Cybershot WX300 screen does work with the LDK firmware (check snakewa's video). But when I watch the comparison with the original screen both look like... Have they alternating columns too? Could anyone confirm this? Do you know of aligned replacement screens we can use?

I can't go and buy every console out there to check their screens. But this being a community... Could you guys please check your devices' screens and tell if they have aligned or alternating pixels?

Thanks in advance!

Edit: I'm listing here the devices we know have aligned or staggered screens. Help wanted!


Aligned:
- RG350 (thanks to renejr902)
- Powkiddy Q80 (thanks again to renejr902)


Staggered:
- RG300 IPS (3", 480x320, RetroFW Type 5B)
- Clockwork GameShell (2.7" TFT, 320x240, Linux)
- G100 (GBA SP clone, 2.8", 240x320, no CFW yet)

Ok guys, I don't mind if it's 320x240. Could you please share with the rest of us if your devices hace aligned or staggered pixels? I can't be the only one preferring aligned pixels.

Look, this is a G100 screen (240x320, rotated, staggered):


This is what it would look like with aligned pixels:


Do you know of devices which look (mostly) like this?
