A quick update to an old post of mine.
I have been spinning wheels researching options on my original post. I know most people could care less, but for those select few that may care down the road, at least the info I have been putting together can at least be archived for a while.
My main point of contention is that I built an arcade cab nearly 2 decades ago with width dimensions that would fit a 25" television as a display, and not only am I using a 25" TV, I'm also using a standard arcade monitor bezel around the display. If I were to replace the TV just because I can't find an appropriate output solution with current PC standards, my options would be to go with either a smaller widescreen display that will fit (and need to come up with some weird bezel), or redesign the cab to become a pedestal cab. One other option would be to locate a 25" computer CRT and replace the TV, but, even then, VGA video card output that fits PCI Express is nearly as old at this point and only adds to the cost of replacing the TV.
Over the last few months, I did a lot of research into video signal converters and the associated issues with converting digital to analog signals. And even though I haven't actually tested many of the options available, I have read that nearly all the options suffer from some degree of display lag, which is probably not a good thing with certain arcade games. I don't have any proof on this, but am simply relying on theoretical reasoning at this point.
While researching all of this, I did find out that the last two video cards that include s-video analog outputs are the ATI Radeon HD 4890 (a slight upgrade to my current 4850) and the NVidia GeForce GTX 285. Both cards are PCI Express 2.0 x16 and both will work with my current motherboard. The GTX 285 looked most promising since it natively supports DX10 (MAME is still using DX9 libraries) and there is still supposedly driver support in Windows 10. With an onboard DAC and drivers that are still possibly supported with today's OS, I was able to pick up a used GTX 285 for a very reasonable price, so this is the option I am going with for now.
The worst part is that, after this, there probably won’t be any more upgrades as SDTVs are now a thing of the dinosaurs, unless better DAC options become available at reasonable prices with lower latency. I'm not holding my breath.
