I can't confirm it definitively for that monitor, but most PVMs are happy to accept cvbs-sync, c-sync, luma-sync, etc. My 14L2 certainly is. BVMs are the ones that get picky, IIRC.

In terms of the hue, I believe that the phase knob is what you're thinking of, but that particular model features the auto chroma/phase setup, so you'll want to just have it auto-detect that using some SMPTE colour bars. You'll want to use s-video or RGB instead of composite wherever possible, though.

I have never seen a 14m4e/u but from what I've read it's like a 14m2e/u but sharper (800 TVL instead of 600). So if true it should be an incredible CRT.

The HUE is ajustable via a knob on the front.

And yes PVMs take composite video as sync just fine

PVMs are pretty tolerant of their sync sources. I don't own an M series, but I've not read about them having sync issues.

It's a nice sharp monitor. 800 lines on 14" is pretty cool looking.

Not all PVMs take anything as sync. The 2950Q for sure needs a pure/stripped sync signal, it won't work with composite as sync.

M-Series monitors are very tolerant of different sync types, and even seem to play relatively well with weak-ish sync sources even.

As an alternative to the CSY-2100 clones, consider the Shinybow SB-2840:

http://www.ani-av.com/shop/product_info ... cts_id=220

It costs only $25 more, supports audio, and outputs correct colours out-of-the-box (does not require tweaking potentiometers to get the right colour).

Cool, it'd be interesting to get a comparison between it, a specialty-av one and a reference Kramer.

I had a question about the SLG Mini. If I connect it to the VGA output of say, an iScan Pro, and then use a VGA-to-YUV cable to connect to my TV, will it work? Or does it require RGB color space?

The Mini SLG uses the sync signal to time the scanline effect, so you those.

This said, I guess the iScan does still output H/V sync even when set to component output. The Mini SLG will then apply scanlines to the Y channel as well (which now contains sync information), so compatibility on the output might be questionable.

Thanks, the SLG Mini is on sale for $15 right now in the official shop.

SNES via S-video through an iScan Pro with VGA out and an SLG Mini. This is on a Samsung PDP 550 plasma screen. The SLG Mini makes the picture really dark, so it's kind of hard to calibrate the colors on the plasma; I didn't try very hard for these pictures, I just drove the cell light to maximum and tipped the gamma to +1. Because it's S-video and not RGB, it does have a wonderful CRT-like effect thanks to color bleed, which you can see in the second picture.

I'll connect to my LED soon, which will undoubtedly fix the brightness problem.

Do any of you guys happen to know what it means when this happens?

It's my PC through an extron RGB 192 to an Ikegami TM14-20R. The game is just for illustration, it does that with everything. The picture holds stable like that, and it happens with both 240p and 480p. It's less distorted at 480i but then it jumps rapidly. I tried both composite sync and H and V seperate. It really doesn't like sync on green. Component input from consoles and stuff work perfecly on this display.

I wanted to report that this didn't work. Switching on the SLG Mini resulted in a "signal not supported" message when using a VGA to YUV cable. Oh well!

I have a quick question about PS2 AV.

I picked up a 14M2U PVM and I've been playing my PS2 on it via Component cables. Now, I noticed while reading the documentation that the PVM supports Sync on Green, RGsB, and the PS2 outputs RGsB. Both component and RGsB are three cable formats, and Y Pr Br versus RGB is just a software switch on the PS2, so I'm wondering why I can't just use the component cable to output RGsB to the monitor. I've tried, and the colors comeout right, but the screen warps and flickers.

On one hand, it's a component cable. On the otherhand, they're just wires. All I can think is that it has something to do with the pin outs on the PS2's connector? Anyone know why, Physically, I can't just use the component cable to output RGsB?

The PS2 does output RGBs in all 15khz modes. You can only get RGsB with a 31khz game, but your monitor is 15khz only.

Thanks! I was trying to look up the frequency of PS2 RGsB, but couldn't find it. Thanks!

Their CRTs were high quality. Probably on par with Panasonic. Certainly on par with Sharp and JVC. Maybe not quite on par with Trinitron, but they were invar shadow mask.

Of course folks around these parts already know about the Mitsubishi Megaview. RGB capable monitor.
Thanks for the info!

Anyone got any experience with this set? It's available for free in my area at the moment:

I managed to get this far by turning on the serration switch and messing with the H shift on the extron. I really don't know how the image is being doubled though. It's not the delay setting on the monitor.

I'm pretty sure you answered your own question already when you used the magic word regarding its availability.

Well I found out that I needed a VSC all along. I tried the 240p DDSP trick on my RGB with a PS2 and it didn't work so it probably won't work with the VSC either. It did remove the interference I usually get on my PS2 image though which is interesting. So like, does a VSC alter the vertical refresh rate you put through it? What if I put a scan line generator on its VGA port and then put 120hz through there to make up for the flicker of removing an interlaced line?

Exactly. Two lines are getting drawn on one.

Dont know if this is the right place for this, but here goes.

Did anyone else check this out. A device (pi2Jamma) that connects to a Pi3 and outputs an 15Khz to Jamma without scalers or HDMI to VGA dongles. The RGB signal outputs straight from the GPIO pins and passes it on to the Pi2Jamma thingy :-)

Can anyone spot any problems with such a device?

I have one of those running through a supergun. It works as it says and allows me to play arcade games on my pvm in 15hz. It's bloody brilliant playing original R-Type or final fight

Ok, but it's not even released yet? Or is it the HDMI->VGA->Scaler->Jamma model you have?

Can anyone identify what model TV this is? It's apparently a 36" RCA of some sorts (North America).

Might pick it up from Craigslist if it's half decent.

Ah yeah. I didn't see that was a new thing. I have the other one. It works great

I just picked up a PVM-1943MD and a PVM-1454Q today, totally free! They were only minutes away from being loaded onto a truck for electronics recycling:

Image

They were used with microscopes for microelectronics work. As expected from machinery operated in a cleanroom, the insides are immaculate:

Image

The focus on the 19" one is a little soft, and convergence needs a hint of work, but this is excellent geometry. I suspect it has been serviced during its lifetime:

Image

Meanwhile, the 13" one is razor sharp, and the only real problem is that it has a bit of ringing. You can see the bright left edges and darker right edges:

Image

Both are 600 TVL horizontal resolution. With a few cap kits I think these will turn out great. My only beef is that they have speakers, but have no audio input for RGB!

The current PVM family:
