My understanding is that the PSX in that mode operates on the same dot clock as the NES and SNES, but I'm not clear on whether there are other differences that complicate the matter. I can get 5x Generic 4:3 on my LG C7 in any of the 1920x1080, 1980x1200, or 1600x1200 modes. But switching to 256x240 optimized mode causes a number of columns to be darkened or skipped. I've experimented with the horizontal sample rate, sampling phase, and video LPF to no avail.
I'm not complaining about generic 4:3 - it looks terrific. But I'm curious to see what an exact dot clock match would look like if it's possible. I'm working with one of the late model, slimline PSOnes if that matters.
I wound up making a few different profiles for ps1 some 256 opt. some 320 opt. I've only tested a small handful of games so far but all seem to work in one profile or another. I had to do lots of messing around with those three settings you listed, changing one till its close then changing another, going back and forth till it dialed in. I am sure once I learn more about what each setting does I'll wonder why I spent hours going the wrong direction haha. Once dialed in it looks razor sharp.
Not sure how much a difference it makes but I am doing this on a ps2 so things might be slightly different then an actual ps1.
Also something to try, I have an LG tv as well but mine is a few years old and I had a lot of trouble getting the optimized modes to work at all until I set TX Mode to DVI. This did cut out the audio so I ran the audio cables into my reciever instead of through the OSSC.
