Questions that do not deserve a thread

I'm getting some slim speakers to go next to/underneath my BVM. I'm guessing that the shielded case of the BVM would mean that speakers might be able to sit right next to it without damaging/distorting the display (which is a problem when putting speakers next to a consumer CRT).

The only bit of the BVM that isn't shielded is the screen at the front. Would that mean that putting speakers directly on top/under/next to the set with the front of the speakers flush with the front of the screen might be a bad idea as there is potential for magnetic interference? If that's the case, would it be preferable to set the speakers back a bit, towards the back end of the BVM?

Cheers

No need to be so anal about that. These monitors were designed to be stacked so I doubt you will have any of those issues. Furthermore, quality speakers are shielded. I use Klipsch ProMedia 2.1 and they are shielded.

[CkRtech]

Even if they aren't shielded, I believe that you can just "break in" your setup after the monitor has degaussed a few times with the speakers nearby. Of course if you move the speaker at all, you'll most likely see the changes in the image on your set.

TBH I'll probably play it safe. I expect I am being anal but I've just bought a super low hours BVM with a 3 year old tube so I don't want to risk it as I doubt I'll easily find another like that. The speakers aren't shielded but the monitor is so I'll just set them back a bit. Thanks for the input guys

but the monitor is

I am not so sure about that. I had mine sitting about 4 ft from my Subwoofer for a test session and the sub caused visible discoloration on the BVM.

[andykara2003]

Oh wow - thanks for that timely intervention Fudoh! I'll definitely set them apart now, your advice is highly appreciated Did the problem sort itself out?

[andykara2003]

Just a thought, Fudoh, I had been planning to place a consumer Trinitron right on top of the BVM and to use both - is that a bad idea for the same reason?

I use Creative T20 II speakers on top of my PVM on their sides, end to end with the bass ports facings outwards like a sound bar. No effect on picture.

Anyway, to answer my own question about a sync stripper circuit, following the mmmoney guide I had built one before and it only worked for Megadrive and Wii, not PS1, PS2 or Xbox even though pin 8 on the scart cables was measuring between 4.98 and 5.03v I guess it wasn't enough amps. So earlier I cut the B end of a USA A to B cable, attached that to the LM1881 and used a phone charger to power it, and I got a picture the sync was bad. So I tried the USB ports on the PS2 and got the same result. So I connected pin 8 up again and the powered usb and it now works for the Playstations (pin 8 alone is enough for wii/megadrive).

[Fudoh]

Did the problem sort itself out?

by moving the monitor 2 ft. further from the sub, the discoloration was gone. And no permanent effects. But to be fair, the sub's membrane was facing the monitor. I was still surprised though to see how extensive it's magnetic field was.

Hi, I'm looking to buy an auto-setup probe for my BVM-20E1E. I think the right probe is a BKM-14L
But I'm not sure as it always seems to be mentioned as a probe for the BVM A series monitors. Does anyone know if this is the right probe for my monitor or do I need an older model?

Cheers.

[Fudoh]

It's the right one. It's mentioned in your monitor's manual as well.

[Zapf]

is the rgb on pal / s-video on ntsc wii output tied to software or hardware? IE could I change the region to something like the UK, and get rgb output?

[blizzz]

It's a software thing, but I'm not 100% sure if the NTSC consoles have the correct resistors and caps for RGB installed on the motherboard.

[andykara2003]

It's the right one. It's mentioned in your monitor's manual as well.

Cheers for that - I'll pick one up as soon as I can find one (easier said than done it seems!)

[andykara2003]

Looking to callibrate my BVM - is there a definitive resource that people here find to be the best for callibrating these types of monitor specifically?

Cheers.

Simple question with probably a pretty complicated answer:

What would be the best/easiest/cheapest way to get 15khz from a PC to a monitor?

I'm planning a mame cab build, and so far I'm leaning towards using a pre-2003 consumer CRT, but I'm confused as to how I would connect my PC to the CRT. Are there any known north american consumer CRT models that accept VGA or DVI? If not, what would be the best way to retain the 15khz quality? Is there an inexpensive processor that could do this well?

[Fudoh]

What would be the best/easiest/cheapest way to get 15khz from a PC to a monitor?

use a video card that fully supports Soft15khz, e.g. a Radeon HD 4350.

[Xyga]

Probable stupid question but would the 72Hz output refresh rate available on my DVDO VP30 be of any use with a monitor known to be overclockable at that same refresh rate ? (Through HDMI)

[Fudoh]

If you want stutter-free playback from NTSC DVDs you need 48Hz or 72Hz. Today's TVs have solved this by simply going 60Hz and dowing the reverse telecine on their own.

Does this also force 15khz on the monitor itself even if it doesn't do native 15 khz? So I could use any old PC CRT with VGA or DVI?

[Fudoh]

I don't get the question. You can run the same video card in 31khz or higher as well, but if you want to use PC monitor you don't need 15khz at any point. Standard VGA (or DVI) from any video card to the PC monitor's fine, but - as said- the I don't get why you were asking for 15khz.

I'd like to run the games in their native 15 khz, but it was my understanding that PC CRT monitors could not do 15 khz. So I was wondering if the soft15khz or an arcadeVGA card would force 15khz on any CRT monitor. I am somewhat new to this so I apologize if my question is confusing. Thanks for all the help, your website is a godsend

[Fudoh]

No, the 15khz was intended for your "so far I'm leaning towards using a pre-2003 consumer CRT" and I assumed you meant a television or video monitor by that, not a PC monitor. PC monitors are usually only compatible with 31khz and higher signals.

[Xyga]

Actually I was wondering if there would be any benefit for my combo-with-xrgb use, maybe slightly reducing the perceived motion blur (?).
I will most certainly purchase a new pc monitor that happen to be able to handle 72Hz, but that's with pc video cards and I don't know if an external processor like the VP30 that happen to have a 72Hz output setting would be able to bring a monitor to behave the same...

[Fudoh]

You cannot lock a 60Hz input to a 72Hz output, so the framerate conversion would kill it all. No more smooth scrolling. For 60Hz sources, 120Hz is the only other option.

[Xyga]

Arf. *facepalm* Of course that makes sense. Stupid me.

It is by any chance possible to play 2nd gen consoles on a sony PVM?
I recently purchased a ColecoVision and there is no cable plug for the RF box. What can I do to get it to play on a PVM?

I've modded my consola for s-video, or composite in the intv case.

They look great. http://www94.pair.com/jsoper/cv_svideo.html

[BlackStealth08]

Ah thanks man. Wasn't sure if I had to mod it or not. This looks like an easy mod.

Are there any audio receivers that can automatically detect if an analog/digital stereo source has Pro Logic/Pro Logic II encoding? I feel like there's no flag data for it, but maybe some high-end receivers can detect properly encoded surround channels and auto-switch to pro logic?
