Software TV Flicker Fixer for A600
« on: April 24, 2011, 08:44:21 PM »
I've recently re-acquired an 15khz Amstrad CTM644 monitor and have it hooked up to my A600 (better than blur I was getting via a composite to LCD converter I had) but the interlace screen modes have headache inducing levels of flicker.

Can anyone recommend a software ECS alternative to MagicTV or a monitor screenmode hack - NTSC is not supported :(

Thanks

As far as I know, there's really nothing you can do in software. Changing the color palette to something less clashy can help, but not much. There were also some screen covers back in the day (sort of like sunglasses that you put on your monitor) that did a little more, but flicker is the nature of the beast with interlace.

Shame. I thought I recalled a tool that was for ECS machines or an early ECS version of MagicTV which I used to use with my Amstrad and 1084s monitors back in the day. MagicTV made the flicker bareable :(

the fact that your monitor won't do ntsc limits what you can do. i used to use a hacked euro monitor driver, but that scanned slightly above ntsc .

maybe you can install visual prefs and tick the 'double line' options. also, as Matt pointed out, tweak your WB palette in visual prefs- make black a dark grey, and white a light grey. might help a bit.

Why you don't get scart cable?? You live in UK and your LCD TV must have at least couble of scart inputs??

Thanks for the suggestion but my first post mentions I'm using an Amstrad CTM644 monitor :) The reason for this is that I had a lead made up 15 years ago so I could use these very cheap monitors. :) Back in the day I was using it with an A1200 + Visual Prefs + MagicTV which gave a very bearable picture.
