CRT bros....you lied to me...
I got the MiSTRE VGA to RGB SCART cable from arcade express, but the image is fucked.
I've used the costume resolution utility, but nothing seems to work.
any ideas on how to fix it??

I thought this was interesting, so I was reading the product description, it has a bunch of requirements, so you should have read them:

100% Made in Spain by Arcade Express
ArcadeVga to Scart cable (Euroconnector) to broadcast in RGB Pixel Perfect
USB with voltage amplifier 5V + 12V
Supports PC / Raspberry Pi / Mister FPGA
Auto power on and change channel to AV / RGB for CRT TV
Requires graphics card that outputs at 15khz
120cm long cable

You should take particular close attention to the thing that says:
>Requires graphics card that outputs at 15khz
I imagine most GPUs don't, since is the frequency that old TVs require and not exactly a modern requirement. I don't even have a way to know if mine does, so I'm not going to risk buying it, even though this does seems like a good product.

>> No.9033508

>>9033495
>>Requires graphics card that outputs at 15khz
This is easy to get around, you just have to edit graphics.ini in C:/Windows/ and change the line hz=60 to hz=15. I don't recommend doing it though since it makes your fps per second really choppy, but if you're playing on an old CTR TV it probably won't be able to input many frames anyway.

>> No.9033572

>>9033473
You're feeding it a resolution that's too high for the display to handle. You need to send it something with a 15KHz horizontal refresh rate, either 240p or 480i (note the i in 480i) for an NTSC display, or 288p or 576i for a PAL display. If your GPU can't go that low consider getting an older GPU with VGA output and putting that in your computer as a secondary GPU, newer versions of Windows will let you set one GPU as display-only and perform all the rendering on the other, more powerful GPU.

Pretty much this zoomers and millennial casuals are jerking off to things they never really understood, never really had. Crash course in how things work, they never touched a computer until long after the concept of PnP existed. Yeah, those CRTs are going to the dust bin. All I can say is welp, there goes your retarded hobby, to the very few people that did their due diligence to understand how things work. Anyway, the people doing the work on shaders is the way to go. TV/monitors are just gonna get better and having documents of how things worked, or at least the resultant, on old devices will provided better results than a haggard CRT that well past it designed lifecycle.

Your CRT is being fed a 720p signal and it can't display it. That's why you're seeing 3s at 480i. You need to send the right resolution to it

This is likely your problem here. You can probably get your GTX 1070 to output NTSC but it will probably require some hackery. Try livebooting Grooveymame and doing the tests and seeing if any display properly. There's so much variation in CRT sets, and video hardware and GPU hardware and drivers you're going to have to try and brute force a solution which is what groovymame will help you with.

You need a DP to VGA adapter and a proper mode set up in CRU.

>>9033483
This is very wrong. Lucky you didn't blow up your CRT.

You need 240p/288p or 480i/576i at 60Hz. Also remove ALL the 31kHz modes. Make sure you pay attention to sync polarity and the timings, this isn't villy-nilly shit and you shouldn't just randomly try without research, you can destroy your hardware.

>>9034053
>>9034379
Nope, all you need is a DP to VGA adapter and a 15kHz modeline, plus any cable that works for you, like VGA to RGB SCART or BNC.
I've yet to see someone who didn't manage to make it work who didn't fuck it up themselves like OP here.

There's no reason to use CRT Emudriver anymore.

There's like two thread on /vr/ right now, CRT thread and another one talking about filters that showcase this method working perfectly fine for all the people who claim this isn't possible.

P.S. I'm not saying HDMI or native VGA doesn't work, I've seen HDMI work and iGPUs with VGA, but only online and not with my own eyes, so I won't claim it does.

>what adapter should I get?
The DeLOCK 62967 gets recommended for VGA and it also works fine for 15kHz output. The adapter does most the work so graphics card is less relevant as long as your drivers let you output a mode like that, from my experience most newer Nvidia cards have no problem, have tested a few myself, currently running a 2070S.

>Also got any proof?
This was on a 15kHz CRT.
>>9036409
>>9036608

Do make sure you get right modelines and don't do what OP did.
To support most home consoles and arcades, 224p, 240p at 59Hz, 59.6Hz and 60Hz will cover most bases and 288p 50Hz. Use a super resolution for aspect ratio correction, RA will switch to the closest mode itself with CRT SwitchRes and even if it's a mode that you don't have, you'll just have slight black bars or over/underscan with still 1:1 output and perfect aspect ratio.

>Why can't I just use DVI to VGA or HDMI to VGA?
You'll just have to test, like I said in >>9037096

>why does it have to be DP?
DP has just less limitations, plus the adapter does the work, so it's a safer bet to know it works.

>and how do I know which resolution works for me?
For starters, try deleting EVERYTHING in CRU for the adapter that goes to your CRT TV (NOT your main display) and copy this one exactly: >>9037094
Restart and try again. Make sure your TV is turned off while you reboot your PC or it send 31kHz modes to it.

>Sorry I don't know jack shit about refresh rates and resolutions
Just glad you didn't break anything.

>>9037150
Like take the checkbox away from >>9033483 1024x768 so Windows can't accidentally select a 31kHz+ mode.
Delete all the other modes you've rated too, from the Extension block also.

Try putting in the mode I mentioned about: >>9037094 under "Detailed resolutions" on the very top. Also click edit on the top/right and make sure under Range limits it's set to V rate 50 - 60 Hz and H rate to 15 - 15 kHz with max pixel clock 60 MHz, check the box that says Include if slot available and press OK.

If you want to add more modes, add them under the extension block, like for 224p and 288p, but first start with 240p and make sure that works, don't do too much at once, otherwise you won't know where the problem is if you have one, go step by step. Good luck.

>> No.9037208

>>9037059
I'm guessing PAL would be [email protected] and [email protected] try both sync polarities negative. If that doesn't work, try the polarities you haven't tried yet.
