Indivision AGA MK2 screen mode problem
« on: August 30, 2012, 02:18:56 AM »
Hi,

I recently upgraded my A1200 with an internal Indivision AGA MK2 flickerfixer from Individual Computers.

Installation went easy and without any problems and the Amiga still powers up fine and boots. However, while the flickerfixer outputs a signal, the signal itself is actually so weird that neither my HDTV (through VGA) nor my DVI monitor could display them.

The HDTV complains about the signal being out of range while the DVI monitor (Eizo 15 inch) displays a heavily distorted picture: the Workbench screen looks like it's been tilted in 3D projection, very weird.

The instructions of the flickerfixer state that the timings are not yet perfect for all displays and things are expected to improve with future firmware updates. However, up to now, there are no real updates available.

Any suggestions on how to fix the timings?

99% of the problems reported here about the AGA MK2 are due to faulty user installations, usually the board hasn't been seated properly and has to be pushed down with considerable force.

Does not sound like a timing issue. Your HDTV probably cant display the low resolutions set, download and use HD720 for your TV, try SUPERPLUS laced @ 800x600 and see if that works on your monitor.
Might be as above said, faulty installation, try the modes I posted then remove and reseat your Indivision and see what happens.
Also make sure you are using a strong enough power brick for the Amiga.

Without the firmware updates and config tool you are going to have issues I'm afraid.

The best you can do at the moment is to use the SuperPlus 800x600 monitor driver and install the BorderBlack utility.

Nice Ports on AmiNet!

It actually works fine when I connect the Amiga to my Eizo display using the VGA signal (using a DVI-VGA-DVI adapter as the display has only one DVI-I input).

The HDTV seems to be very nitpicky about the timings. It didn't work with an old Sun Ultra 1 as well.

Thanks for the suggestions,

I have similar issues - i could not get it to work with my HDTV at all.
On my Philips 170c LCD monitor (quite old now but works fine) -
I had to fiddle with the screen position and size setting in the monitors
own menus till i got the best i could.

Also changing screenmodes on the Amiga helped - I installed some monitor drivers HD720 and (I cant remember the other one someone here help me please!). You should try these and see what work for you.

In the end I think its clear that a lot of people are having less than satisfactory results with the picture quality and we just have to wait for Jens to get his bum into gear and drop us some firmware / driver updates to fix these issues!

I've got two MK2's in both my A4000 Amy's, but I use USA spec Westinghouse 1080X1920 monitors; the 32 inch one is a HDTV with VGA & HDMI input, and the 42 inch is just a monitor sans TV (VGA, HDMI, 2 DVI, and composite).  Both work very well with the Indivision MK2's with some minor vertical banding seen when no video output is displayed.

I personally think it is a pixel clock mistiming issue between the AGA MK2 and the monitor, and yes it is soon to be addressed. Jens is a good guy with a lot of Amiga hardware "on his plate."  Better for us users all around though.  I'd prefer him working for us, than not

Using VGA and you will have issues due to different pixelclocks and you will get vertical lines. I Use DVI and since it's digital no sampling required and no vertical lines :)

DVI doesn't work for me at the moment, that is what I said in my original post. Using DVI on the Eizo display gives me a heavily distorted image.

Well, did you the Amiga up using DVI or VGA? I've got only issues over DVI and this case is already mentioned in the installation manual of the flickerfixer and should be fixed with future firmware updates.

VGA works fine for me as well. Just my Sharp HDTV doesn't seem to like the signal but it also just displays "out-of-sync" when I connect my old Sun workstation.

Yes I know, but getting a second hand DVI monitor might be worth it to get rid of vertical lines until the new firmware/ConfigTool comes for the Indy. (depends on how much they annoy you ofc)
So I would try the Amiga on another DVI monitor to be a bit more sure thats it's an issue with that monitor and DVI, ive tried mine on 7 monitors and all worked (varied results and a lot of black borders on some but worked).

I myself got tired quick of the lines so went DVI, the reason I stayed a few days on VGA was because then you can adjust the screen position to get a near perfect fit in all modes.

I use VGA so I can use an external monitor switch between the AGA MK2 output and Radeon 9200 output.  My 32" HDTV has only one VGA and one HDMI, and lacking both a DVI/HDMI switch, I use VGA.  The other way involves using the remote to swith from HDMI to VGA each time I switch between the two.  Same problem with the 42" monitor with the 2 DVI inputs, I need to use the remote to go between.  HDMI switches are abundant, but I'd prefer a DVI-d switch, much harder to locate (KVM's are quite expensive).

Yes, I might take the Amiga to my work place, we've got dozens of DVI monitors sitting around. There's certainly one that works.

Well, no. It's not an issue with the monitor as the manual explicitly states. Jens said he knows the DVI output doesn't work with all monitors yet and he will be fixing the issue in the future.

I suppose that some monitors have just a higher tolerance for improper signals.
