Reply To: Confused about how OSSC works with PS2

[Res1s7]

OK thanks Harrumph and BuckoA51. At first I thought I was just being a bit thick with everything to do with the OSSC, but now I’m beginning to understand the concepts I can see that what I was getting into was a Jujitsu master class and crash course in video processing all rolled into one ! Maybe VGP should give out some kind certificate ?

So far …

1. The reason that I have a box within a box on my display is that the larger box represents the full extent of the CRT display that the PS2 is expecting to find. The gap between this full box and the smaller actual display of the game is where the edges of the curved parts of the actual CRT tube would have been. Is this called “overscan” or is that something else ?

2. Having grasped that this device is actually well established way of doing this I beginning to understand that I can alter the timing to adjust the final image geometry. I already shifted the image left/right using the horizontal timing adjustment in the OSSC menu. What I don’t understand is if I can enlarge or shrink the final display using some of these timing settings. Is this possible ?

3. Scanlines. Someone suggested that you can use the OSSC post-process scan lines to mask the flicker effect of the “bob” interlacing … “I have the OSSC black out the repeating lines from 480i games. So essentially no more annoying bob deinterlacing flickering while still getting the benefit of no added lag.” ( source ). I tried that but could not reduce or remove flicker. Am I barking up the right tree here ?

So I’m slowly getting used to the OSSC with the PS2. I takes a bit of getting used to as its as if an actual CRT display is my HDTV !
