Preset for CRT TV (1080i, 480p and 576p)

[ID4]

Hi

I have an CRT that workd at 1080i, 480p and 576p.

What can be the crt_range for this CRT?

Thanks!

Hi ID4,

Assuming it's 576p@50 Hz (31kHz), you can just take the arcade_31:

crt_range0  31400-31500, 49.50-65.00, 0.940, 3.770, 1.890, 0.349, 0.064, 1.017, 0, 0, 400, 512, 0, 0

...and do these changes:

crt_range0  31400-31500, 49.50-65.00, 0.940, 3.770, 1.890, 0.349, 0.064, 1.017, 0, 0, 400, 576, 800, 1152

(yes, it will handle 1152i@50Hz too)

Hi Calamity!

Thanks you! Really it supports 50 and 60 Hz modes at 1080i. 480p and 576p are supported too as I said.

This CRT supports 576i and 480i too, but it scales to progressive so quality is lost.

If you want 1080i@ at 60 Hz you'll need to increase HfreqMax a bit in that crt_range.

This CRT supports 576i and 480i too, but it scales to progressive so quality is lost.

Yeah that's because it the TV works at 31 kHz natively so it needs to upscale 15 kHz signals.
