Amiga 1200 RGB problems?
So I have BL 702A monitors connected to my Amiga 1200, A500 and A600 Using RGB to VGA adapters. So the problem is that both my A500 and A600 give a crystal clear image while my 1200 gives a bit blurry picture. Not bad but a bit more blurry vs my A500 and A600. Also I noticed the super frog image, igame logo is more yellow (probably like it should be) for my A500 and A600 while my 1200 shows it more orange.
Could this be a problem with the RGB on the 1200? Maybe some resistors or video dac? |

Solved my issue I think. First of all my Amiga 1200 was running 32 colours in Classic Workbench VS 16 colours on my A500 and A600. Turning it to 16 colours in the A1200 made the igame logo look yellow on the A1200, just like the A500/A600.
Also, it seems like A1200's RGB is outputting quite different from A500/A600. When I turned gamma from 3 to 5 and contrast from 50 to 70 on my BenQ BL 702A I pretty much got the exact same picture I have on my A500/A600 with Gamma at 3 and the contrast at 50. So now it looks perfect to me. I got the same level of blackness on the A1200 with gamma at 5 as I have in my A500/A600 with gamma at 3 on the same monitor. I also read that Amiga 1200s RGB works through a video dac and does not output the exact same way the A500/A600 does? Anyway, I'm happy with the picture quality now. Also, one of the reasons why I think the BenQ BL 702A is so good for Amiga use, appart from it handling 15KHz and 50Hz PAL with a nice picture is that this monitor has sharpness settings. At default it's set at 1, and this gives it free "anti aliasing". If I turn it up to 2 it will look similar to my sony 17" LED connected to my AGA MK2 via DVI. The letters and everything becomes blocky. So I think this low sharpness mode is really nice for the Amiga. Last edited by turrican9; 18 January 2016 at 00:09. |
