Appiah's comprehensive 15KHz monitors list of caveat emptor

[th4t1guy]

I can confirm that Asus VZ249HE works with 15khz modes through VGA using standard Commodore RGB->VGA adapters.
Both NTSC and PAL look great, but interlace flickers badly. Also, image will be slightly stretched for widescreen and theres no option to set aspect ratio.

Sure.

https://15khz.net/ <- the list presented from github readme.

https://github.com/planeturban/15khz <- repo

Edit: My end-game is some kind of android and ios app where one can scan the barcode of the monitor to get its 15khz status. Just to remove the need of everyone having their own 15khz-tester.

you can add the Acer K242HYL to the list (it's not there but I got the info from EAB anyway). It's LCD and takes 15KHz VGA input from A1200 or CD32 with riser

Added at 15KHz.net

Good job with 15khz.net! How about adding a column about (Amiga) interlaced modes handling?

That's the beauty of repos.. Just fork, add and create a pull request..

Anyone ever try NEC ea241wm? I read it is supposed to accept 15khz. Just wondering if anyone has tried and what kind of results.

Yup, works fine with Amiga and Atari ST, at 50 and 60Hz.


You can either show an unscaled proper ratio image in the middle of the screen, or, if not it shows the complete image stretched to 16:10.
There's no option to set the aspect ratio.
Otherwise it's great.

Thanks Mikerochip

I wish I had waited for your reply. I ended up getting a Samsung SyncMaster 913N 19" because I saw it on the list https://15khz.net/

But I have also read it doesn't work with Amiga according to this list

http://www.retropix.com.br/lista-de-...aceitam-15khz/

So now I dunno

[rabidgerry]

So this monitor should be removed from the list Samsung SyncMaster 913N 19"

It does not work when I connect Amiga to it. I was using a commodore RGB to VGA adapter. Gutted. I will have to sell the monitor on now.

I can't write this often enough. Leave PC monitors be. Go for 4:3 LCD TVs (800x600 or 1024x768). They are cheap as dirt, guarantee PAL support and have Amiga-friendly ports.

I have had very little success with LCD TVs - the picture quality is generally awful on the 4:3 ones as they are now ancient, and all the ones I have tried have had significant lag.

I would however welcome any suggestions for something that works well!

Add to this the fact that outside of Europe.... they *don't* have Amiga friendly ports. SCART wasn't a standard adopted in Australia - LCD TVs here typically have Composite and S-Video (if you're lucky). You will find the odd unit with SCART - but it's very much an exception rather than a rule.

The RetroTink 2x SCART looks like a decent solution to all this hassle - then you can add RGB SCART to any HDMI display. Not as expensive as the OSSC and much easier to use.

You probably tangoed with older/crappier 640x480 panel TVs. I would imagine those are not very good. They can't even cover the full PAL resolution (they will display the image, but it will be yucky). And most smaller screens are like that.

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).

Yes, that is unfortunate But S-Video isn't all that bad. A buddy of mine even says that he prefers S-Video to SCART because SCART is too sharp And S-Video adds just the right amount of fuzziness. Anyway these pics were taken of the S-Video display. Judge for yourself.





Don't forget to click "Load full resolution".

I’ve got one of these - it’s fixed resolution so you are at the mercy of the scaler in the display in terms of image quality. I have found so far that TVs give a better image at the expense of lag, and that modern 4:3 PC monitors have no lag but are business focused so non-native resolutions look awful.

I haven’t tried one of the modern fancy “gaming monitors” yet.

[rabidgerry]

Which one of these lists is the right one?

Is this?

As mentioned before it lead me to believe Samsung SyncMaster 913N 19" was ok for Amiga but it appears it is not so who ever is looking after the list should strike it off.

Unless I am doing something wrong?

****edit**** the monitor does work using a GBS8220 but there is a lot of noise for some reason.

@Mikerochip

What is the lag like with the NEC?

Also what option on monitor allows you to shift between 4:3 and 16:10?

I still might get one of these monitors.

[Mikerochip]

There's no real lag. It's the same as plugging a PC into it.

As I already said, there's no option on the monitor to allow you to shift between 4:3 and 16:10

You can display it in a tiny 4:3 screen, or stretched to 16:10. There's no other scaling options.

Also, unless you do a few hardware mods on the GBS8200, the display isn't great, with every monitor.

I'm confused.

If there is no option to allow you to shift between 4:3 and 16:10 then how are you able to

You can display it in a tiny 4:3 screen, or stretched to 16:10. There's no other scaling options.

Do you mean do this via the Amiga?

Well I have the GBS8220 modified using GBS control firmware which is lag-less apparently. But the whole point if my interest is so I don't have to use the GBS with this monitor. I only mentioned it because the monitor I tried which is on the list of working with Amiga does not, but it does work using the GBS as you would expect.
