Hey guys, so I've finally gotten my hands on a professional grade CRT, and want to get some of that beautiful GroovyMAME action going. The monitor is an Ikegami TM2017R, and I found a cheap a Radeon R9 350X to use for my GPU. One thing I'm concerned about is that my W10 PC already has a gtx 1060 6gb installed, and I'm hoping that I can keep it in there for more demanding games on my LCD monitor. Would I need a dual boot setup for this?

Other than that, I'm just trying to make sure that I'm ordering all the right hardware components to get this working as nicely as possible. This is what it should look like once everything gets here in the mail:

R9 350X > DVI-I to VGA adapter > VGA cable > Extron RGB 201rxi > 5BNC cable > Monitor 

Any possible caveats to this setup that I should be thinking about? And are the cables linked below the correct BNC cables for going from the Extron to the monitor? I was watching a Youtube video of someone using a similar Extron and a BVM, and it looked like there was only a single sync cable coming out of the Extron / into the monitor instead of two like the cables below, but he said they were 5BNC cables so I'm a little confused about that.

My sincerest thanks for any wisdom you guys can provide, as I start out on what is sure to be a long journey to get this working nicely.

The Extron RXI will convert the RGBHV signal to RGBS on the fly. I use the 203rxi myself and it works great. Good luck!

Which means you'll only need a 4 BNC setup. :)

When it comes to calibrating your monitor specs, make sure you turn of the horizontal and vertical centering functionality of the Extron or you'll be forever chasing your tail.

Turn that stuff back on once your GM is calibrated and you want to introduce hardware (i.e. consoles) that require manual centering.

Thanks. So does that mean that a 5BNC cable won't work?

No. You'll just have a spare BNC. ;)

In theory there's no issue installing both an Nvidia GPU + driver and a separate AMD GPU + driver, but i'm not sure we've had reports of anyone actually doing it with crt_emudriver. Would be nice to know if it works seamlessly, or if you get any hiccups :)

I will definitely let you all know how it goes! I'm super excited to get started on the project. I've been looking through tons of guides but I'm still not sure how crt_emudriver actually works, does it just act as a replacement for the ATI drivers, and theoretically not have any effect on my ability to output a "normal" video signal using the Nvidia card and drivers? Would a fresh Windows 10 install prior to getting started help to reduce possible issues?   

Edit: I should maybe add that I have no real need to use both monitors at the same time, except maybe to use the LCD for audio. Not sure if that changes anything.

Treating that as two questions: yes, crt_emudriver is a video driver you install instead of the normal AMD drivers. And yes, in theory it won't interfere. In practice, i would guess you're going to have an interesting time sorting out which resolutions are allowed on which screen.

Would a fresh Windows 10 install prior to getting started help to reduce possible issues?   

For sure. Anything you can do to minimise confusion the first time round is going to be a godsend.
