Hello folks, first of all, what a nice place you have here, congrats.

Well, I have the classic noisy 480p image: I have tons of different DACs, consoles, cables, TVs and so on, so long story short: I only need a inline LPF dongle to clean the 640x480p image from my GBS control and my extron IN1508.

720x480 works great in all my escalers and even my cheap wii2hdmi clon does a better job outputing 720x480p than its big brothers (outputing 640x480p). After MONTHS of research (I'm not exagerating) I realized that it was not my cables, it was not the caps, it was not a bad grounded device, it was not the power supply etc etc etc etc. So don't you bother to tell me to modify the gamma, the phase and so on, please, I'm not a tec guy but my common sense works very well if you give me a couple of months.

So, could anybody kindly share the schematics for an "image cleaner" wich could cut off any wave above the 640x480p resolution (RGBHV via D-sub 15pin cable)

Thank you very much.
