To be honest, it's hard to beat a BenQ BL702A or BL 912 connected directly to RGB with finetuned pixel and phase clocks. Only thing missing is scanlines. But they look really good still. |

When you say noise in the picture, are you referring to RF noise? I wonder if the ribbon cable that is used would be improved if it were shielded.

In certain resolutions like if you make a custom 720x576 Vsync profile there is quite abit of noise (waves going over the picture). However, on most other resolutions there are no noticeable noise. And in general there is slight ghosting in the picture, just like it was with the ECS V1. I know people tried with shielded cables on the V1 to get rid of ghosting without it helping. But the ghosting is not so bad that it ruins the picture.

Unfortunate to hear shielding did not help. I am seeing some ghosting in addition to some faint diagonal lines. I reduced the length of my VGA cables that did help to improve the picture but only in a small way.

Occasional stutters are the best I was able to manage with the Aga mk2 as well. So It will not be a demo watching board for me, I can deal with this discrepancy in workbench use, so that board is in my music Amiga. Quote:

Yup, same setup here nowadays.
Indivision AGA MK2 is in the 4k, but when the machine is used for any games or demos the OSSC comes out.... |

Would the OSSC be better than the Indivision for demos that have mid-demo resolution switching as there can be a few seconds where the monitor display is black whilst the monitor is switching resolution?

One or two positive things about the Indivision scandoublers that don't get mentioned very often is they can use any type of standard monitor as long as your willing to accept frameskipping at 60Hz. Or 50Hz with the right monitors. And since you put them inside the Amiga it's a very clean solution with no cable clutter.

I hope that I have some time tonight to get a resolution that shows overscan and will try your 1472x1060/736x530. Provided that I'll figure out how to change the right values. The benq probably switches to 1920x1080 because 1472 is higher than the standard resolution of 1280 and it's the same ratio as 1280:720? The firmware is probably generic with widescreen monitors. |

I tried some things tonight, and although I seem to get now how I can create a resolution that allows the overscan to show up, I can't get it to look as nice as the predefined 640x512@50Hz with scanlines enabled. I've set the resolution to 736x530 and even to 720x576 but it looks a bit distorted, although my bl702A stays at 1280x1024.
Btw, how do you adjust the refresh rate? Can that only be done with the Pixel clock slider on top of the VGA mode screen |

To make this work correctly you need to put the VGA resolution at twice the Indivision resolution. To get a clear picture the Indivision resolution must be able to be exactly half of the VGA resolution. However, the Vertical part of the VGA resolution can be the same value as the Indi vertical resolution. Putting the vertical resolution equal in both VS twice in VGA VS Indi will make the monitor use different resolutions for each case. So in your case you would want to put 1472 x 1060 for the VGA, Vsync on and start to tweak the pixel clock until the monitor switches to "1920x1080" and then set 736 x 530 in the Indi profile. I know this is not easy to understand, took me alot of experimenting |

Bad camera but it looks good in real life. Shows the overscan in Pinball dreams correctly. However, there are a few games that will cut off a very small bit of the horizontal overscan. I have made successful 720x576 profiles (monitor switches to 720x576 and with full overscan) but get alot of noise (waves) in the picture on that resolution. So the one I'm using here is the best I've found so far that will also allow enough overscan for almost all games. Also, for pixel clock, you could manually change the number instead of using the slider. Remember to press enter after you change the number. Note: These are the settings I use for the BenQ BL702A monitor which is pictured below.

Thanks for your explanation! I don't think I understand all of it yet and I will take some time to digest it .
I only created a new resolution based on the 640x512 PAL profile and adjusted the resolution to 720x576. I kept the VGA mode at 1280x1024 50Hz. The refresh rates of this mode are 57.5869 and 54.6366. It doesn't look as nice as your image yet. Probably because of the reasons you describe. When playing games I don't notice it that much though and scrolling seemed a lot more fluid than at the predefined 1280x1024 60Hz. And a lot more of the screen is shown. BTW, I don't seem to be able to save my profiles. I get a program failed error (#80000003). |

Those screenshots look really good! I do not see any ghosting as others reported and the scanlines are very natural looking. Interesting that you are mapping to a 1920x1080 resolution on a 4:3 monitor. You would think your BenQ would not accept that at all when it says your optimal resolution is 1280x1024.
I was curious if you have the latest firmware installed. It was supposed to allow more overscan area. I was having enough difficulty with mine that I removed it and I'm just using a cheapy SCART to HMDI adapter for now. My monitor is an HP E271i and it doesn't quite know what to do with the default 800x600@72Hz. The image is shifted vertically and my manual adjustments are not saved. I hope that if I can figure out how to customize the screenmodes, I can output something it will accept better. This particular monitor also has an annoying problem that it does not auto-sense a signal input over VGA. I think it is a bug in the monitor firmware as all other inputs do auto-sense.

Does the Indivision ECS V2 have a HDMI output yet ? Or am I missing the point ?

So the BenQ will accept 1920x1080@50Hz and make some sort of sense of it? I am going to have to try a few things on my setup now as that potentially changes everything! (not an Indivision) Surely that has to just be something strange going on. |

I have two of these. They have horrible input lag and oversaturrated colours. I do not recommend these for gaming because of the horrible input lag. Other than adventure games or demos where the input lag wouldn't matter that much. They also upscale the picture in a way so you don't get smooth scrolling.

You're right there is some input lag, but for a casual gamer (like me) this is the most affordable way to use hdmi monitor.
