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!

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

- 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?

Odroid Go Advance has 480 x 320 screen which allows pixel perfect scaling for GBA. The screen is an Ilitek ILI9488.
My Portable Devices: Sega Game Gear, PSP 3000, PS Vita, Nvidia Shield Portable, GPD Win, GPD XD+, Bitboy V1, Coolboy RS-97, PAP KIII Plus, LDK Landscape, 1Up-Pix Portable Landscape (RPi 3B+), Anbernic RG-350.

Maybe this should go on the Other Game Systems board, but here are some close-up photos I took of Mario on various handhelds. I do include a shot of the LDK which has a staggered TN panel:

My handheld collection isn't exhaustive. By all means, share your Marios.

Shots taken during the start screen loop when Yoshi hatches. I used unfiltered and no scaling (or integer-scaling) for all of these:


GP2X F100:



RG 350m:

Shield Handheld:


And, using Super Mario Advance 2:

GBA Micro:

DS Lite (Top):

DS Lite (Touch):

Of course, I'm getting close to 40 so it's not like I can actually see the screen when I'm playing anyway.

Just checked the PocketGo, PocketGo 2 (original model), and PocketGo 2 (new model), all seem to be aligned but with a few differences:

PocketGo generation 1

PocketGo generation 2 (original)

PocketGo generation 2 (new)

The first generation PocketGo display panel has the red, green, and blue sub-pixels stacked horizontally while both second generation consoles have sub-pixels stacked vertically. Additionally, the second generation PocketGo is supposed to have an evenly grey wallpaper but looking at the sub-pixels shows that adjacent pixels appear to be display slightly different colours and these arrangements are actually slowly alternating between the two colours (red + green vs red + blue).

Odroid Go (ESP32) has aligned pixels (horizontal subpixels).

I would have posted the unlicensed NES version of SMW to continue the bit, but it isn't supported by my currently installed version of Retro-Go.

Does anyone out there have a production RG280m? There's been confusion over what kind of screen it has and I would really like to see it settled.
