I would guess there are only two options:
- 1:1 pixel centered (which gives you a tiny image)
- full screen (which stretches the image to full 16:10 screen)

There is no "keep aspect ratio" (or whatever it may be called on various hardware) option to have a full height 4:3 picture with black bars on the sides.

20 and 21 inchers, on the other hand, are more modern, and can be found with 800x600 and even 1024x768 panels (although there are still cheap 640x480 ones, so everybody be careful and check the specs before buying).

I’ve tried a few actually - none of the really old ones but a modern ish plasma and a couple of current gen wide 24” screens (All via a Retrotink 2X-SCART and via built in SCART if they have it). I haven’t found any panels made in the last 10-15 years with an 800x600 or 1024x768 panel so if you have any recommendations I would appreciate it.

Yup, sorry, this.

There's 2 options: unscaled, so, tiny 4:3 320x240 etc screen in the middle, or, stretched to 16:10.


I can take a picture of both, if you're interested.


Any game or resolution you particularly want to see, to compare against?

Aye if you can take a picture of both settings.

So give me your workbench screen on both settings first.

Then a few games to try:

Micropose F1

The First Samurai

Virocop

Ruff n Tumble

Gloom Deluxe

Mortal Kombat

No Second Prize

I could go on. Do a couple of these can't have you arsing about with my list of games all day

Do you get vertical bars with your display? Those bastardin things I get on both Amigas?

And are you using a buffered RGB to VGA adapter? Or just plain one with no buffer?

[amiman99]

I have Samsung SyncMaster 912N (I got it for $3 in Thrift Store for a project)
The monitor works partially, basically no PAL resolutions, or 50Hz
I made some tests:
NTSC High Resolution - YES
NTSC High Resolution Lace - YES
NTSC Low Resolution (320x200) in Games - Yes
NTSC Low Resoultion in WB - NO
PAL High Resolution - NO
PAL High Resolution Lace - NO
PAL Low Resolution in games - NO
NTSC Super High Resolution and Lace - YES, but hard to read, not useful
Multiscan - YES
Productivity - YES
Productivity Lace - NO
DoubleNTSC - YES
DoublePAL - YES
DoubleNTSC Lace - NO
DoublePAL Lace - NO
Double NTSC No Flicker - YES
Euro72 - YES
Super72 - NO
Euro36 - NO

[rabidgerry]

I might try getting one of these Samsung SyncMaster 204B

[peceha]

INFOTRONIC L2130S (21 inches)
Displays everything.

NO INTERLACE IN LACED MODES

Only one drwaback: to display 320x256 corectly first you need to set 640x512 resolution, after that 320x256 will be fine

[Lord Aga]

Wow, that monitor looks really good! And a MVA panel to boot!
You connect it via VGA I suppose?

What about 50Hz? Smoothie smoothie or choppy choppy like Dells?

iiyama ProLite X2474HS.
Not only supports 15kHz modes, but also have flicker fixer.

- can the aspect ratio be set to 4:3?
- I hope it doesn't flicker fix progressive modes?

It's not my monitor, just fount information on PPA. I was asking owner of it about more specifications, maybe he write more informations.

[Solo Kazuki]

Ok, i have more info. It's more complicated and depends on exact model. Some supports only PAL/NTSC lo-res and doesn't accepts neither laced modes nor Super72/Multiscan/etc modes, some accepts all modes - it probably depends on firmware version. This exact model with blue screen should work with Amiga, other models with black or other random screen could not. But to be sure, if You can, best way is to check this before buying.

Anyone had issues with a Acer g276hl kbix? I bought a referbished unit and I'm not seeing any video on it. My 1084S died on me so I was trying to get this working with a newer monitor. Another monitor I have benq, at least says out of range when plugged in.

I have found the Dell P1917S (5:4 1280x1024 IPS 19") works with a 15Khz signal, I'm using the Commodore adapter. I haven't managed to tune out the clock/phase lines yet and it is a horrible mess in interlaced mode.

[DerSheriff]

Working in industrial automation field I managed to "keep some days" some oldish displays now and then, many with VGAs, usually used as HMIs or for supervision. Nothing worked with Amiga.

The best image I got in 640x256, without using anything else than a simple DB23-VGA cable, is with a BL702A.

LG M1717A also works with Amiga, but the image was not so good. Quite wavy and washed out

[brett71]

Is there a North American equivalent to the BL702A? Or any other modern monitors that are available in North American that can do 15kHz?

Looking for recommendations.

I don't know, I know that also the BL912 works, but never tried it. I bought a BL702A a year ago, but it was already quite difficult to find. I think they're being phased out. Of course beware of "marketplaces" offerings.. I saw some used ones on ebay Italy at 2x or more the original brand new price.

What model exactly? I was trying new Dell P1917S and it has only partial support (it's my addition here). Could You check it more, e.g. put here exact product code and/or date and origin of production?

Sure - it's a P1917Sf made in China in November 2016. It works in 50hz and 60hz at 15Khz with no juddering but the vertical lines make it generally unpleasant to use.
