Fudoh's ode to old display technology

[lettuce]

Has anyone had any experience with the Ikegami monitors?

I know a man who has.

any ideas on the out come??

[K-2]

So I have 2 BVM-20F1 and like them very much , but I was wondering what expansion board I need to get another set of RGBS inputs?

The idea being that I could have my Saturn plugged in along with my Super Emotia without swapping a load of wires and breaking my neck in the process.

I bought a 24N NTSC decoder and that allows me to plug in component/composite but as far as I know you can't use it for RGBS. I also bought another main input board (the one that comes stock on the BVM) and tried to use that, following the order of installation outlined in the manual, and got it register as a new slot in the input configuration menu, but everything I sent through it was garbled and it made everything going through the other input slots garbage as well...Tried plugging all the outputs with 75ohm BNC terminals also and no luck.

He loves it. He also has PVM's so he has decent references to make against.

you can't. But I think you can switch the component inputs on additional boards to external sync nevertheless, as long as you feed the sync line into the single SYNC input on the stock-board. You can probably add a simple composite switch to the EXT.SYNC input to use more than one sync source.

Hi everyone!

How can I check the number of hours in a BVM-20G1E?

Thanks!!

[Ed Oscuro]

Did you already search out and download a copy of the service manual?

[Fudoh]

I assume that it's the same menu as on the F1 units. The hours are displayed in the STATUS submenu.

Thats good to hear, i wounder how the JVC broadcast monitors compare as well then

I was using a 2006 composite/s-video only JVC TM-H150CG before coming across the PVM-14L2 i currently use.

It produced an incredibly bright and sharp picture through composite and was a lot more tolerant to funky video signals than the PVM, pretty much in the same way standard crts do.

It had an issue where the picture was very, very slightly bent (C shaped) which i think was due to the lack of sufficient shielding around the picture tube.

The difference in quality became all too obvious when opening up both monitors though... The Sony is *much* better built than the JVC, complete with proper shielding, actual Sony parts and tube as opposed to a generic chinese tube inside the JVC and a chassis that looks like it's been made out of various bits and bobs.

On a different note, some Ikegami models are said to be re-branded JVC/Victor units.

Finally bought a PVM-14M4E ! Anyone have the owner/service manual(s) ? Or where I can buy them ?

Thanks.

@Fudoh : do you know this PDP model > PDP-V420EA ? A seller is selling it but I think that is mislabelled.

[fagin]

PM me your email address.

certainly a 402. If it's in your driving range, pick it up! The price is good!

[fagin]

A Sony BVM-D24E1WU was up on eBay yesterday and I lost my bottle after my bid was surpassed at £850. It went for just over £1000 in the end. I probably would have cried had I'd won it for £850 in any case.

ok thx, I will see.

About PVM-14M4E, when it say RGB/COMPONENT,does it means that YpBpR is supported or I need a transcoder ?

Lol, nice try .

[akumajo]

Received a PVM today, quick test with a PS1 and quality is good. Is the noise normal while using those monitors ? I remember that my old crt was doing same noise, It just seems to be too loud. I hope that you understand what I mean .

[ryu]

you mean buzzing sounds? that seems to be normal with pvm units, yes

[kamiboy]

My PVM's are whisper quiet. Often I forget that I've left them on. They are both L series models, L2, and L5.

I think CRT buzzing in general is a sign of old age.

aren't the L models pretty recent though? i think L5 models have been produced around 2005.

anways i've played hundreds of hours on loudly buzzing pvms from the 90s - never having had any problems with those.

[akumajo]

ok, does not sound good (this is a 14M4E)
I will check in menu if there is something related to hours .

[kamiboy]

Buzzing should not mean that a display is on its way out, only that it has been well used.

I am just guessing though. No buzzing could be a sign of a CRT with a better build. In my experience though, the older the CRT the louder the buzzing.

MY L2 is pretty much mint and does not make a pip.

[fagin]

Is it a buzz or a squeal / whistle type noise?

[cyborc]

I have two pvm 20M2MDU. One is NOS and one is used. The used one makes popping sounds for about 5-10sec when I turn it off. It sounds kind of like when bubble wrap is popped but not quite as loud. The NOS one does not make the sounds when powering off. Should I be concerned? The unit works flawlessly otherwise.

[NWrain]

My BVM when I first got it made a noise so loud people thought it was some kind of fire alarm. Now it just makes a small eeeeeeeeeee noise.

[lettuce]

Is there any PVM or BVM models we should avoid for retro gaming?

[IronSteel]

Hello,

Sorry for not making a new thread. Got a relatively cheap 20M2DU. Have one problem with it though.




As you can see there's horizontal colored line going through across the screen near the top of the screen. I can "make" it go away if I use the overscan button but then the image gets cut off. Is it possible to fix?

[mesmer]

I got my rca->bnc adapters in the mail, so I was able to hookup my PS2 and PS3 through sony component cables, and finally test out my BVM-A20 at resolutions higher than 240p

PS2 GG 480p:




PS3 Kof 1080i:
(Was using a tripod & longer shutter speeds, so moving chars are blurry)



Took some close-ups to try to see if 1080i is any better than 720p for 1080p games
Kof 1080i:




Kof 720p:


looks the same to me, and 720p has no flicker, so that is what I'll go with for originally 1080p games.

[Fudoh]

very nice! thanks for the pics. The monitor can hardly resolve the 1280 TVL of a 720p signal, so that's better than 1080i in every regard.

I'd say for PVM models stay away from ones that are composite only, and for both better stick to the models made in the 2000's because unless you know a unit's work history you can pretty much count on it having many thousands of hours on it already.

For BVM's make sure they at least come with an input board for analoug RGB as most come with digital SDI boards which are useless for home consoles and securing the proper input board could end up costing you more than the TV.

Also certain BVM models do not have any picture controls and require a seperate controller unit to do that. If the controller is not included, yet again more hidden extra cost.

[Fudoh]

All BVMs come with YUV/RGBs as a standard (non-removable board). SDI is always optional.
