Bought a Dell 2007FP for dedicated Amiga use - no 15KHz

[AmiNeo]

Hi guys. After getting my miggy 600 finally set up and working, I decided to grab what I've been lead to believe is a great monitor for retro computing / consoles, the Dell ultrasharp 2007fp. Unfortunately it doesn't display using my scart adapter I was using on my main monitor because it isn't wide-screen so doesn't accept the 1080p signal. I tried connecting via Component RCA which it has, but I forgot about the 15KHz signal the miggy puts out...

So, my dilemma now is, is there a cheap fix for the 15 KHz signal these days or does anyone know of an RGB SCART to HDMI converter that will output 5:4 resolutions?

I have seen HDMI conversions for miggys. Are these a potential solution?

The standard buffered VGA adapters won't convert a 15Khz signal to something the 2007FP will use, you'll need a scan converter like the OSSC etc if you want to do that.

Some other points:

The 2007FP is a 4:3 display;
The 2007FP doesn't do 50hz or 15khz input over VGA or DVI, but 2001FP models made prior to June 2005 will;
I'm surprised the composite input doesn't work as the one I tried does accept a 50hz 15Khz input, with very low quality and high input lag.

In the end I gave up with converting the RGB output as the quality was never better than very average and bought an Indivision (digital HDMI output) which I am very happy with.

None of my monitors are 15Khz capable but a VGA adaptor gives a very acceptable crystal clear picture. All I had to do was copy the VGA Only monitor driver to DEVS/monitors.

I am using the Dell u2410f; a 24” widescreen led monitor with composite, component and 15khz vga input.
In general, all dell monitors with composite/component inputs are 15khz capable over vga
second hand. Last purchase just last week.

I've been using an RGB scart to HDMI which I was happy with but it sadly only outputs to 16:9 aspect ratios. It has a switch to swap between 720p and 1080p. Just too modern for the miggy.

I thought the point of it being buffered is to adapt to that? Seems to be some examples online of people using them on the same monitors? Maybe they have something else too.

That’s my only issue with non transparent sales.

You ask how they work and whats the benefit of “extreme super duper edition limited gold” actually means to be met with hostility

The amount of different versions of the same item just confuses everyone.


Buffered is what it is. Not a converter.

Only reason I assumed it would help is because it was recomended to me when I posted my issue really. I'm guessing not from this conversation and if that's the case, my search for a solution continues...

Too right! Anyone who claims that these VGA adaptors convert the signals is basically talking out of their rear. All they do is take the RGB signal from the Amiga and send it to the monitor via the VGA cable. You do need the extra monitor driver(s) as listed in sales thread tho.

Buffered and visible line removal variations are out there and yes, which one to choose can be confusing. My VGA adapter is just the buffered variety, nothing fancy. It lets me have my Workbench running quite happily in 800x600 on a 4:3 ratio 19" monitor.

Next for me is the RTG side of the PiStorm32-Lite. Never done anything like it before but I know a nice man, Doug aka 'Mr 10 Minute Retro Amiga Cast' who shows me the way via his Youtube channel.

But I'm guessing it wouldn't work on mine? 15KHz support is needed still?

 

[Sardine]

Yes and no

No wont work standard amiga video modes are 15khz and you need a 15khz compatible monitor

Yes it will work with dedicated 50hz screen modes typically in workbench and productivity software but not until workbench has loaded the monitor driver so scrambled or out of sync until loaded up. pretty much useless as anything that changes the screen mode would screw up your display. A bit like using a pc graphics card on a mac. You see nothing until the fixed screen mode loads up or until you load summit else and then nothing works again. This also means 99.9% of games will not work especially if you boot from floppy

*looks over at ProjectX running via VGA adapter

*boots Elite

Those pretty graphics are really disturbing, where is the black screen?!?!

 

[Sardine]

On a non compatible 50hz display show me the wizardy without an upscaler

 

[miggymad]

Everything I throw at my Amiga and VGA monitors work, be it from WB or floppy disk. YMMV of course but I can only go by my personal experience and I stand by it.

I don't have any non-compatible monitors here.

 

[Sardine]

Then your display is 15khz compatible

If it was as simple as using a vga adapter then the indivision mk1 or any other upscaler wouldn’t exist.

 

[miggymad]

@Sardine

You would expect an A1200 using the original Commodore VGA adapter to work if the monitor is15kHz compatible yes?

So why doesn't it?

Curious.

At the end of the day, the modern day VGA adapter works for me and countless others judging by the feedback. I am more than happy to recommend them purely on my own experience.

 

[Sardine]

I think your confusing the op with “vga” its not vga from the amiga its rgb over the same shaped 15 pin plug that can support pc vga screen modes but the amiga is natively rgb 15khz which most pc vga monitors don’t support hence the reason the flicker fixer / scan doublers and indivision exists like the gb 8800 range

@AmiNeo have you looked into RGB2HDMI I believe there is an A600 version
