Daewoo CRT Settings

Unread post by splintercell70 »

Can someone with experience with CRTs help me out? I'm using component cables (VGA to Component) and I'm having strange issues. On 1st screen (Main screen where you select core) it in constantly is motion (wave-like motions) also, many cores don't look right and really bad on the portable console cores (GBA, wonderswan, etc...etc....) with a badly deformed edge of the screen.

Note 1: These current setting work perfect on my Sony Trinitron. So I think these setting need to be slightly tweaked to work better on DAEWOO, but I have no idea what to change.

My DAEWOO CRT is model DTQ-20U4SCU

My current Mister Settings for CRT:

Code: Select all

If this config works on Trinitron it should work on Daewoo. You can try to change composite_sync=1 or switch the SoG switch on your IO board, but I doubt it'll help. Not all CRTs are made the same though and maybe your model is too sensitive to MiSTer's signal or something like that. Or maybe something in the service menu needs changing, if it has been previously tweaked.

Did you try any other 15kHz source on this TV (eg a Playsation or some other console)? Also, after recent similar post: are you sure you actually switched to AV/Component on the TV and all your inputs are in order?

change composite_sync=1
Did nothing

switch the SoG switch on your IO board
Screwed up the screen so I switched it back to previous position

Not all CRTs are made the same though and maybe your model is too sensitive to MiSTer's signal or something like that.
Maybe I'm just screwed. All of my physical systems work great on this Daewoo CRT Tv (SNES/N64/PSX). I guess the Mister just isn't very compatible with this CRT.

If anyone else has a Daewoo CRT and it works without issues, can you please copy/paste your config file here so I can compare it against mine?

Thanks in advance!

Not 100% sure but I sem some of the later consumer crt TV weren't able to display half res progressive video modes; just 480i or 480p.

Try:

Code: Select all

forced_scandoubler=1
