low quality rgb output

good morning to everyone and nice to meet you!

...I hope you can help me with the problem I have ...

I own an AES rev. 6 to which I made the RGB mod. that consists of cutting the three tracks on the PBC.
despite this, the RGB output, both connected to a modern LCD and an old CRT, appears with a lot of shadow and ugly, as shown in the pictures.

the rgb cable was made by retrogamingcable.co.uk

... has this ever happened to you?

another info:
the composite output still works, it still works and seems to be producing an even better RGB output, but obviously less defined, and this is strange because when cutting the traces on the motherboard the composite output should not stop working?

the 3.6 have some disturb from oscillator, you need to cut the 3 trace of R.G.B and put a 120ohm "best quality" for each from dac.

Yes, make sure you add resistors on the RGB lines, your picture just looks too bright making it look bad.

thank you for your quick advice!
... i have alreaday cut the 3 traces, but actually the very strange behavior is a "checkerboard" effect on all color displayed.... then SNK logo, too, at bootup it is not displayed as a clear "blue", but with a checkerboard effect...
there are an easy tutorial on how to add the resistors?
