CRT TV 100Hz Scanlines and 240p games

Hi,

I tried several combinations of your modeline unfortunately without success.

Now I’m sure this TV cannot accept 100hz input.

With your modeline I managed to change the pixel clock I could increase to 63hz maximum (the picture was not good little jumping) at 64hz I have a black screen so in my opinion 100hz input is impossible.

I don’t know why but with a 320x240 @ 60 modeline, crt switch turned-off, I have 60fps with the vsync on or off. I did a test with an another TV before the release of crt switch (a small 14 inches vhs samsung combo) I had only 30fps.

Another thing, I do not know what happened, when I had the 320x240@ 60 modeline activated, I only had a quarter of the screen when I started the game.

Retroarch was fully activated in full screen

I managed with a custom aspect ratio and the menu of retroarch put a resolution of 640x480 with an interlaced shader I saw the scanlines, against the flicker was still there (headache), retroarch crash soon after.

When I restarted it took the resolution of 320x240 and I had to change my aspect ratio to fit the TV screen

I wonder if this TV can accept 480p @ 60hz with 15khz input by scart.

I did not manage to calculate a pixel clock for a 480p @ 60 15khz input modeline.

If it’s possible, could a modified interlaced shader reduce flicker?

What do you mean by “double 50hz pal”

Thanks, and I wish you understand me

Edit:

From a 720x480p modeline

"720x480p" 35.496 720 782 949 1128 480 488 494 525 -hsync -vsync

I have this, maybe it can accept 480P ?
