I think I may have a new project.Īnyway, I start this thread for the purpose of inviting discussion about LCDs that can accept RGB input with the appropriate synch. But the fact that some of them can do 24 kHz reminds me that I have a disused Sega Model 2A arcade board sitting around that I've never found a screen for. None of these guys give you the magical 15 kHz horizontal synch, or if they do they only do so through a composite or component analog connection meant for TV input and not for RGB. Scan Frequency - 20 to 83KHz (Horizontal) x 50 to 76Hz (Vertical)

Out in the Internet archives there's a dysfunctional Commodore Amiga discussion board where they explored exactly this topic and came up with a short list of candidates: Is there, on the current market, a commercial-available screen that can handle the RGB horizontal synch frequencies we love from our game systems and arcade cabinets? I also recalled that there are now many retro arcade cabinets in the wild that use LCD screens, which are lighter and cheaper than CRTs but which are also likely connected to proprietary emulation systems not unlike PCs. It occurred to me that it's been quite a few years since anybody has asked the question. Sadly, I struck out because the monitor bottoms out at 30 kHz like every other VGA tube known to man. I piped up because one of the monitors has lovely BNC connectors on the back and inputs for both separated synch and composite synch, which in my mind raises the chance of 15 kHz horizontal RGB to fifty-fifty.

So my workplace is disposing of old computing equipment, and it will cost them less for me to haul away a couple of old tube monitors than it would to pay the environmental disposal service to do it.
