CRT Switchres on PC Monitor

What connections to you have on the 15khz CRT?

Kuipumu · 6 July 2018 14:25

Only has a composite, I was trying to do a RGB mod on it but, that did not worked. I will try to connect from VGA to composite, at least is something.

Alphanu · 6 July 2018 18:26

You won’t get composite forest from RGB, you’ll need a video converter to encode the signal from RGB to composite. As you can’t video data on the centre pin and sync on the outside.

If you have tried a RGB mod did you tie vertical and horizontal sync together. This will create composite sync. You’ll need to use diodes to protect each one.

There not to expensive. Have a look here.

I tried running it without declaring the Modelines, but I still get the same error, I throught the problem was because im running dual screens in the Xorg setup, but I still get the same problem, either If I declare the Modelines or not.

Here is a copy of my Xorg.conf.

Do you have any idea of what I am missing?, could you help me?.

Alphanu · 13 July 2018 23:35

Well I’ve just started working on 31khz switching.

Check out the video.

@hunterk I need some help with menu options. I have no issues adding them but I can’t seem to figure out how to have them change E.g. the superresultion option. I need to have it change when pressing left and right. There needs too be a few more options for swithing now especially with this 31khz mod.

Kuipumu · 14 July 2018 00:08

Great.

Did you got it working on 480p?, What are all the resolutions you made?, Which options you used in Xorg?, What files you modified for the compilation?.

Alphanu · 14 July 2018 00:27

In the video sonic 2 switches to 480i. Why would you want 480p? However, 480p would output fine.

I have not changed anything in Xorg! Also I have no pre-installed resolution. Retroarch does all the hard work for you.

There are still some bugs that need sorting and a few menu options that need to be added. However, I don’t foresee this taking to much longer to complete. Maybe two weeks to a month.

hunterk · 14 July 2018 00:32

Man, that’s really awesome. I never had any luck producing 31 khz 480i modelines, so that’s really exciting to me.

I just asked Twinaphex if he could help out with adding the options. We need the super-res to be selectable, do we need a switch to choose between 31 and 15 khz? Are there any other options we need?

Alphanu · 14 July 2018 01:21

I’m thinking that CRT Switch should now have it’s own submenu. I think in total there will be 5 or 6 options.

Superres.

15 - 31khz 240p toggle.

Ouput ID and number. E.g. HDMI-1 or DVI-1 *

31khz compatability mode. Two or three options for hz.**

Custom refresh is sync does not work. E.g. 138hz. ***

it will speed up swithing and fix a resolution switch bug. This will only be needed for Linux.

**A few pre-set porches to help centre and or sync the image

*** used if pc monitor needs a different sync. Also for windows users when installing modlines through CRTEmudriver.

There may even be a couple more towards the end.

I’m trying to think of options that would help ease the process for the users.

Kuipumu · 14 July 2018 01:17

Wow, but did you made a custom compilation?. I try to run at 3840 without any modeline added and it still dosen’t work, and the refresh rate runs at 60 Hz. I also tried to run at 480i but it has not worked for me, what is that CRT model you have?. I have no idea why It dosen’t work this way for me.

hunterk · 14 July 2018 01:33

Ok, yeah, that probably necessitates its own submenu. Twinaphex has asked us to open an issue on github that explains all of the stuff we need and he’ll handle adding the options to the menu.

EDIT: I went ahead and opened an issue. Feel free to add whatever:

Kuipumu · 14 July 2018 03:55

For some reason I can’t get to make it work correctly, I get this in the log when I try to run the emulator without adding the modelines.

I’m not shure if its something related to the nvidia driver, I will need to try with nouveau.

The same happens if I try to do it in my custom build compiled for 138hz, it fails with 2560 or 3840, It only works by adding the modelines at Xorg.conf and overriding any check from the nvidia settings, but, the same error of Retroarch trying to delete the resolution happens, probably the issue in Github will figure how to make it work, but I leave this for the record or if someone have an idea of what might be causing to not work in my case.

Alphanu · 14 July 2018 08:50

Go to terminal and type xrandr. What does the output say?

Most importantly what is/are the connected device/s?

Kuipumu · 14 July 2018 15:50

I only have the CRT connected in the analog DVI port.

This is the ouput of xrandr:

The 3840 resolutions don’t work on my monitor for some reason, they have a very low khz making them unable to display at 120hz.

Ok that answers it. Currently RA only switched DVIX or DVI-X. New code is being incorporated to include other IDs like DVI-I-X

You would need to edit the ID loop with the display server to include your ID. If you need it now. There is a bug within this loop which causes unessisary swithing. If you wait a few weeks I’ll have all the new code ready to merge.

It should have those DVI-I-X or DVI-D-X to cover all cases.

Do you know any way to change the monitor ID?

I do this is the reason for the upcoming merge. DVI-I-x and DVI-D-x are rare IDs which is why they were not initially included.

Excellent, I just saw it on the issue. I would be really good if every other possible ID is included, there is probably some other weird ID out there.

Standard IDs will be included in the menu and an option for config where odd IDs can be added manually by the user.

Any new update on this?.
