Reply To: Scanlines Issue – Gamma and Contrast Effected?

[marqs]

With scanlines set to 100%, every other row (linedouble mode) should look identical to without scanlines, and every other should be pitch black. At 50%, R/G/B value of every pixel on the masked line is reduced by half of the maximum (not scaled by 0.5), so basically every color component below 50% of the maximum becomes 0. Offset (=brigthness) and gain (=contrast) adjusments are not there to compensate any post processing but to allow correcting possibly non-ideal analog input signals. Note that running scanlined OSSC output through any scaler can cause final picture look bad in many ways, so I’d try 1:1 scaling mode on the Dell monitor if it supports that.
