Another modern monitor supporting 15kHz - AOC 24G2U

[Craigt]

Hi all.

I've found another modern monitor which works well when hooked up to an Amiga via a RGB to VGA adapter (mine is the buffered version from AmigaStore.eu).

The monitor is an AOC 24G2U. It can also be configured to a 4:3 screen ratio, and has built in speakers. All the Amiga's main screen modes work well (including DBLPAL/DBLNTSC), apart from Interlace modes which are displayed but flicker quite badly.

Vertical banding is visible - I'll have a play with some settings to see how much it can be eliminated.

Here's a few pics and a video of it running SlamTilt Pinball. I switch between screen sizes in game to demonstrate the monitor coping well with the change.

does SHRES work ? For the vertical banding there’s a VGA adapter being sold on AmiBay that helps.

Yep. Here's a photo of PAL:Super-High Res: https://imgur.com/DRrr03P

and PAL:Super-High Res Laced (Laced flashes really badly): https://imgur.com/zSntZ3r

I've tried a few other NTSC screen modes and they fail. Here's a list of the ones I've tried:

PAL:High Res - WORKS
PAL:High Res Laced - WORKS (bad flicker)
PAL:Low Res - WORKS
PAL:Low Res Laced - WORKS (bad flicker)
PAL:Super-High Res - WORKS
PAL:Super-High Res Laced - WORKS (bad flicker)
DBLPAL:High Res - WORKS
DBLPAL:High Res Laced - WORKS (bad flicker)
DBLPAL:High Res No Flicker - WORKS
DBLPAL:Low Res - WORKS
DBLPAL:Low Res Laced - WORKS (bad flicker)
DBLPAL:Low Res No Flicker - WORKS

NTSC:High Res - WORKS
NTSC:High Res Laced - WORKS(bad flicker, blurry)
NTSC:Low Res - WORKS
NTSC:Low Res Laced - WORKS(bad flicker, blurry)
NTSC:Super-High Res - WORKS
NTSC:Super-High Res Laced - WORKS(bad flicker, blurry)
DBLNTSC:High Res - Input Not Support
DBLNTSC:High Res Laced - Input Not Support
DBLNTSC:High Res No Flicker - Input Not Support
DBLNTSC:Low Res - Input Not Support
DBLNTSC:Low Res Laced - Input Not Support
DBLNTSC:Low Res No Flicker - Input Not Support

does super 72 monitor 800x600 work?

Not in a usable way, no. The monitor accepts the frequency and the screen is stable (no flashing), but unfortunately the text is illegible.

Just tried MULTISCAN: Productivity (640x480) and that's working fine, with a nice stable image.

well ok

did u tried copying "VGAonly" monitor to devs to see if this fix the issue?
do you found a way to fix the vertical bands? in which screen mode are more visible?

Na, didn't help. When VGAOnly is in there, super 72 reports "Input Not Support".

Nice find. The Original G2U isn't available anymore around here but there's a G2U5 in some stores. I just wasn't able to find a technical difference, but given it's another model number it's a bit of a gamble to just buy it on a hunch ?

I heard the vertical banding can be fixed changing the resistor values of the 3 RGB resistors in the adapter
do u know something about this?

nope I just bought a ready made RGB to VGA adapter that got rid of the vertical banding
