Fudoh's ode to old display technology

[amontre]

I recently got this PVM which i couldn't tell what model (no sticker at the back). It works perfectly when i connected my wii using component.

But when i connected it using scart (via scart to bnc) to my megadrive or saturn, i got these faint horizontal bar moving up.

Am i missing something ? bad cable ?

JVC TV lookin' good! Does anyone know which model numbers were component ready?

[atheistgod1999]

Yeah, how do you get rid of hum bars? I have them to a much smaller extent on my 13" PVM.

[tacoguy64]

They got a few of those JVCs around my area, you guys are tempting me

Figure I'll post mine here too, since I recently joined the cult. Here's my Sony PVM-14M4A:

Quite happy. Yes, that's a cut-down cork to the bottom-left - at some point the poor thing lost one of its feet. :<

On a related note, I'm sure the question has been well worn out at this point, but it bears repeating: any hard-set precautions regarding tate? Did a brief search and saw that unplugging it and leaving it for ten minutes before AND after rotating it is good practice, is there anything else to consider?

[Einzelherz]

My precaution is to not TATE an aperture grille screen. That's why I bought a shadow mask.

Is there a way of knowing which your monitor is? I've been thinking of using my PVM14n6u for TATE stuff

I don't know if there is a list or anything, but if you google whichever model you find out in the wild there is plenty of info on the JVC website on the old models. I was able to find out the inputs/line count/comb filter/physical dimensions/weight etc.

If you have a Sony CRT, it's an aperture grille. There are also some early 2000's flat sets with it after the Trinitron patent ran out- Mitsubishi Diamondtron is the other big one I've heard a lot. Easy to tell by the bars of phosphors instead of circles/dots.

Huh! Good to know. Guess I'll keep it right way up and feed it horis. :B

[atheistgod1999]

Why can't you TATE an aperture grille? Too heavy? Is 13" small enough?

[Einzelherz]

I never said you can't. I said that I choose not to because I'd rather not risk disrupting the wires.

[atheistgod1999]

I never said you can't. I said that I choose not to because I'd rather not risk disrupting the wires.

Oh, OK. Do the 13" ones have them?

All aperture grille screens are composed of wires.

Took some half decent pics of the XM37 Plus the other day so... meh, might as well post them (I don't think I've posted 240p games pics of it yet).
The color temperature my camera picked up is not on point though. What I saw with my own eyes was different. It is also a bit sharper and more vivid in person. Oh well, still gives an idea of what the monitor is capable of :

Someone is offering a Sony BVM-D32E1WU 140km from where I'm living. This past weekend I drove there to take a look at it and to test it. I brought a PS2 and the necessary cables with me. I also bought a control unit prior to my visit since the monitor doesn't have one anymore.

Sadly things didn't work out the way I imagined. The monitor didn't do much besides powering up. This was my first time using such a monitor. And the current owner doesn't know anything about it either, probably picked it up very cheap (or for free) and is now trying to make some money with it.

I really could use the opinion from someone experienced with these Sony BVMs.

Okay, all the thing did was to power up when you push the power supply switch at the back. The display turned on and displayed a blue screen with white text saying "Initializing". That's it. Nothing after that. It did not react to the control unit. It also did not react to the PS2.

The question is what is the normal behavior. What should happen after this "initializing"? Would it start to display the video of a plugged in video source such as the PS2 by itself or do you need to press some buttons first?

What also was curious is that the colors changed the longer the monitor was on. At the beginning it was blue and later drifted into magenta-ish and then green-ish colors. Could this be a sign that it is broken or could this be fixed by recalibrating it?

Also it seems I plugged the control unit into the wrong port. I plugged it into that board that's on the far left of the unit (looking at it from the back). Judging by videos I looked at afterwards the control unit is plugged into the port that's at the bottom in the middle. But can it also be be plugged into that board on the left?

I also have a question about the cooling of this monitor. I could hear active cooling. I read the HD SDI card has cooling. Does the monitor itself have cooling or would it be silent if you remove the HD SDI card?

In any case, this monitor is huge. I knew the measurements from data sheets but seeing it in person is always something different. What a monster. The thing was stored in the basement and was standing on it's side, it almost looked like a refrigerator.

To the people having trouble finding RGB input cards for their JVC monitors. Panasonic sold rebranded monitors that used the same cards but with a Panasonic model number. Try searching for BT-YA702P for the Panasonic RGB card and BT-YA701P if you need the composite/S-Video input card. I own a JVC DT-V1710CG which came empty with no inputs. I bought both Panasonic cards for it and both fit and at least the composite/S-Video card works, I didn't get a chance to try the RGB one yet.

I'm trying to locate a BT-YA702P Panasonic RGB / Component card. I would really appreciate help with this. Would possibly be interested in trades.

[OldSchoolGamer1203]

I think I got it figured out now, in regards to the best monitors for specific resolutions, would it look something like this?

Sony BVM-20F1U = 240p & 480i (Both 4:3)

Sony BVM-D20F1U = 480p (4:3)

Sony BVM-D32E1WU = 240p, 480i, 480p, 720p & 1080i (All 16:9)

Yeah you gotta fiddle around with the menus in order to get going but I don't think the monitor is bad. Could something like the degausser not working correctly which isn't too bad of a problem.

In anyways you should give him the low ballest of all deals and run with the monitor.

The 20F1 has no advantage over the D20F1, so the D20 just adds 31khz compatibility and has otherwise the same quality for 15khz sources.

[Einzelherz]

And beyond that it's subjective.

Setting up an emulator box to use with pvm/bvm and have a few questions:

-it's better to go with XP or 7 ?
-i know there are mame versions optimized for crt emudriver. How retroarch/other emus work? Is pcsx2 ok with low resolutions?

[LDigital]

I have a bvm 2011P which is by far my favourite 4:3 monitor due to the punchy image and level of geometry options available. It really is amazing. Anyway I recently moved home and noticed that the image has rotated a few degrees anti clockwise in its new home. I can't for the life of me find a tilt or rotation anywhere on the control board. Does anyone know how to adjust this?

I've had to deal with this more than once with my 2015S, as changing which direction the monitor is facing affects how it's aligned with the earth's magnetic fields.

One option is to simply alter your setup so that it's facing the same way it used to.

The other is to open up the BVM, loosen the clamp on the yoke, and manually rotate it. This is what I've done, and it's actually not that hard. It's a little scary in that you have to have the TV on while you do it, though, unless you want to turn it off and on a million times while you hone in on the best position. Put a hand in your back pocket and wear rubber-soled shoes.

You'll want a screwdriver with a large female hexagonal tip to loosen the clamp. It looks like it will take a normal Phillips screwdriver, but the screw has weird notches that make it hard to turn.

What is the best option to play 480i games on a pvm?

I researched a bit and came up with sync strike->extron rgb->pvm
This shoul down scale 480i to 240p, will it look better than feeding 480i directly?

If the game has a native resolution of 480 lines you'll lose 50% of information. If it's 240p linedoubled to 480i you'll get a sharper and more stable picture.

[jhonny_d]

Good, and about 480i native games? Is a scart cable enough to get the best image?

[kamiboy]

Yes.

Hey Everyone!

So I've gotten the opportunity to get a used JVC TM-1700G from work (I work in Post-Production) for basically the cost of a cab ride home. Looking at the monitor and online, it looks like it only takes Composite and S-Video inputs, which no slot for a component or SDI card . However, I'm going to to be using this for my SNES, which is currently connected via composite to my 50" plasma (Panasonic st60, so not only is it muddy looking, the input lag is awful.) is it worth the $45 or so cab ride for this use, or should I bite the bullet and get a real deal RGB capable CRT?

[jhonny_d]

Thank you for your answers and patience! For each answer I get more questions pop out
Fudoh's page is proving unbelievably helpful during my research .

Let's say I want to hook a VGA 31 khz source to a 15 Khz monitor (480i and 240p, PVM/BVM), looking at the downscaling solution I found these possibilities:

-Extron Emotia + Extron RGB interface
-Extron VSC + Extron RGB interface

Would these solutions yeld the same results or is one better than the other?
