/vr/ - Retro Games

I just got a B&O MX4000, and I'm struggling to properly adjust the geometry settings through the service menu. I messed around in the 240p test suite for a couple hours, trying to make the grid test look nice. But every time I thought it looked decent, the linearity and scrolling tests would look off.

I don't even really understand what I'm supposed to be aiming for, if I can't make it perfect. Are the outer edges of the red squares in the grid test supposed to be visible on screen? It seems impossible to get the image linear, so things get distorted when scrolling near the edges.

I've skimmed through the guide in the OP, but I'd really not want to open the TV, I don't know what I'm doing, and don't trust myself.

Need some advice. I know it's nearly impossible to get the geometry to be perfect as this, but is the aim to have the red boxes inside the screen?

On my PVM, I can align it almost like this picture but most of my games don't look right. I want it to fill the entire screen. Should I stretch the size of the screen until the red boxes are almost out of sight? Or ideally should I leave the red boxes intact?

Oh, yeah. Also a pattern like this helps when trying to fix geometry.
You can generate it with the 240p test suite, or some games actually come with it in the options menu (Makeruna Makendo for SFC/SNES being one)

So first time actually doing the grid adjustment, also probably doesn't help I don't know jack shit about CRTs

Is it harder to do on a flat CRT? Are flat CRTs shit by design?

Because I can't really seem to hit the mark, it's always distorted, and even when I think I found a happy compromise I start playing some side scrolling game and it's the distortion is so noticeable.

I had no idea this shit was so fucking hard.

Something that doesn't seem to be explained.
When using the grid what should be displayed.
Do you leave the red in when underscan mode is on? Do you only show white normally?
