Indivision ECS V2 ghosting

I still think it is highly sensitive to what monitor and vga cable that are used. Like for instance. My Sony monitor....

If I use it on my IndivisionECS V2, then I have never seen such ghosting on vertical scrolling in my entire life. It is in pinball dreams and fantasies. It is like really bad. And it is not only when using the IndivisionECS V2. When using that monitor on a 486dx33 ISA-Only motherboard with an Orchid ET4000 ISA card and playing Dynablaster in MS Dos 6.22, then all vertical lines will start to make a wave motion 0.5 centimeters to each side. And other games have troubles.

Yet I need that monitor, as it gives perfect picture on my other Amiga500. That is a revision 8a.1 board, full ECS chipset and with an ScanPlusECS scandoubler that only outputs 50hz refresh rate.

Yet on anything non-50hz and non-Windows98, it really sucks.

FWIW, my ghosting issues are also on a Samsung - to be precise, a Samsung SyncMaster 701T (really 701, not 710).

I would like to add that using the GGLabs A520HD for Component output from the Amiga RGB to a CRT TV the ghosting is present for me. It is much less visible but I did start to notice it when working in PPaint the other night. So for me at least it is not limited to only the VGA out from the Indivision ECS v2.

Any news how to fix the ghosting. I have a similar problem with my ECS v1.0 on my a600. I was interested in buying another one for my a500 but i want to solve this issue first.

Dear Jens, has there been any fixes with ECS Version 1?

thanks

I'm experiencing ghosting on both a viewsonic and a BENQ monitor only when i connect the indivision ECS V1. I checked the RGB out on a 15khz BENQ monitor and the ghosting disappear. Does JENS replies here?

I do reply here, yes. I've purchased a Samsung monitor, as over in the German part of this forum, people reported that Samsung monitors show the worst ghosting.

Jens,

just to let you know that my ViewSonic VA-951S connected to my A500 with Indi ECS V2 also experiences major ghosting issues.

K.

Edit: same configuration with ECS V1 did not experience ghosting.

Ghosting here too with my HP E271i (1920x1080p) monitor.

I have to say, I was so discouraged by this and not having luck with the default screenmode that I actually removed the ECSv2. I also did not realize before purchasing it that the RGB port would no longer work. That's my fault for not researching it more.

Like others, I find the screenmode tool very confusing. I am glad to see software updates (as well as firmware) are coming in so I may want to give it another go.

I am curious about something. If it is found that source of the ghosting can be tied directly to the ECSv2's output signals, does that mean future FW updates can tweak these signals in such a way to eliminate it? When I hear about other monitors not showing the problem, that makes me think the monitor is just doing a better job of cleaning up the signal.

The RGB port does still work. Probably a small detail that you're missing? Cable connected at both ends?

I have a suspicion that it's a mismatch between source and target termination - just need to find the time to unpack the Samsung monitor that I purchased just because of the ghosting reports here.

Sorry, Jens. I was certain I read that the RGB port would no longer work since the actual Denise chip is taken out of the loop with the v2. Glad to hear it!

Thanks for the info on the ghosting. Hope you are able to track down the source.

Another month has passed - any news on this?

I was hoping to send my Micromys V5 back together with the Indivision, but I guess I'll have to do that separately...

Still working on that flash issue, but we're making progress. My next step is to investigate the Indivision ECS V2 flash in an A600 setup. Already spoke to a customer on the phone, so I can replicate his setup exactly like his and hope that I can really brick the unit, so I can see what's going on. That'll be after easter, though. The A500 has now moved to the table where the new Samsung monitor is, so it's closer to where I will do the ghosting test. Getting there!

To replicate the flashing issue, then try my setup, and flash an IndiECS V2 with 1.6 firmware....

Then use the following thing's:

- Amiga 600 Revision 1.5

- a604n with a "full-pin" socket.

- Kickstart 2.x version 37.350

This should make you able to replicate the bricking.

2.5 months since the last update... any progress?

I've tried connecting the Indivision ECS V2 to the VGA pass-through of my Piccolo RTG card, and the image is smearing much worse when routed through the Piccolo.
With my limited understanding of electronics, can I suppose that it really is a matter of bad/missing termination there? How can we solve this?

I've also tried on three Dell monitors of different years / models, a Vizio 46in TV from 2006, and a brand new Philips 32in UHD monitor. I have tried 6ft cables shipped with new monitor, several 3ft long cables with thick ferrite blocks on both ends and really heavy cable. Nothing makes any difference. I am confident enough in my soldering skills to perform any modifications to the board that might be needed.

I have ghosting aswell, with ECS V2 and a Benq G2400W monitor.

I can at least reproduce ghosting at very high output frequencies on a Samsung monitor. Seems like Samsung uses a different termination. I hope to have time for more investigation in the next few days.

The updates are appreciated Jens, even if infrequent. I just want to post a pic of the artifacts I see on each of my monitors tested for reference.

Basically high contrast areas like white to black transitions bleed or badly ghost across the screen. It is very distinct in the test pattern of the Individision settings app and in the PPaint UI. (Moving the window on the test screen causes distortions in the pixels to the right all the way across the screen.) You can also see color bleed in the orange and yellow into the black of the color palette.

For now I have moved on to using an OSSC which provides a perfect picture but I would rather use an integrated solution for conversion.

Any news on what to do about this? It would be nice to actually use the Indivision ECS v2 output at some point if it can be corrected. It has been over a year since it was first reported.
