Fudoh's ode to old display technology

[Fudoh]

right now speculating if this could be caused by a PAL60 signal for sync.

Unfortunately I only own NTSC systems, so I can't check this. Maybe somebody else owns a BVM along with a 60Hz-modded PAL system ?

[SGGG2]

Fudoh, how does the Pioneer handle odd resolutions like the NES's 256 x 224?

[Fudoh]

lines are mapped 2:1. Horizontal resolution doesn't matter - we're talking analogue signals.

[SGGG2]

I have a line on one but it's got prominent image retention. Seller says he was told if you leave it on with TV fuzz (snow) for several days it would go away. Does this sound right?

[ryu]

i'm afraid you're unlikely to ever get rid of that bar.

[Fudoh]

yeah, the row of missing pixels is certainly a defect.

And the image retention (his words) look more like proper burn-in to me. I doubt that it's going away.

[SGGG2]

Thanks guys! I thought it looked hopeless, but since these don't pop up too often I wanted to be sure.

[Ed Oscuro]

Somebody sure precisely farmed that set into the ground! Bet it was in front of some shop or headquarters for a building, surely. I'm sorry but that set is done; needs to be thrown in the bin.

I would say the seller is insane but I remember some years back there was argument about whether channel logos could permanently burn into plasmas / LCDs; some people (i.e. the channels) insisted you couldn't "burn in" on these sets but of course they were just trying to cover up bad programming behavior. Nevertheless, that false idea is out there and some people cling to the "it's not a CRT so it can't burn in" story.

You can really get burn in on an LCD, how long does it take?

[Fudoh]

depends on the panels. I've seen the windows task bar burn in after a year of 24/7 use on some panels, while it doesn't burn in in 10 years on other panels.

Just stumbled across these pictures....

However I have a few consoles that just don't work right.

RGB modded PC Engine Duo




RGB modded SuperGrafx




This same effect happens with the Sega Master System and also AV modded 7800, Colecovision and Intellivision consoles. Anyone have an idea what causes this?

Solution proposed was "APC/VCR"-Settings ...


Currently, I got a very similar problem with my PVM 2042 QM.
Picture is unsteady at the top, but rocksolid at about 1/3 down.

Don't get it, never seen something before ....

I got no idea on how to adjust that. What does AFC do? Why does this happen?
When at home, I hope I find a AFC trimpot inside ...

whats wrong with the TV/signal?

Please enlighten me,
ninn

[kamiboy]

I doubt it. That AFC setting is only present on certain high end large screen BVM sets.

What system are you using?

Hello all,

My office is getting rid of a Pioneer PDP-v401. I see that Fudoh mentioned he had one in his original post but nothing else about this exact model other then that the 402 is better.

Is this worth taking for N64 (modded)/Saturn/SNES/ps1/gamecube Scart? Other than Scart to BNC, is there any other equipment needed to connect to the RGB inputs on this monitor? Picture quality of this display?

Thanks for the help, I'm really new to this stuff!

[RGB32E]

Fudoh, look what shenanigans you likely instigated!

I've recently come across a set of PVM's and was wondering if you guys had any feedback on the model #'s that were given to me:

BVM-20E1U
BVM-14E5U
PVM-20M2U
PVM-1954Q

The BVM-20E1U is one letter difference from the BVM-20F1U. It seems to have the same user manual too. I am not an expert on PVM's but this one seems like the logical best choice since everyone raves about the 20F1U. Is it more or less the same? Any thoughts are appreciated!

[Fudoh]

The E1 is the "deluxe" version of the F1. 1000 TVL instead of 900 on the F1.

[Christoph]

Nice! Thanks for that.

Think the 20E1U is definitely the best option out of that list?

[Fudoh]

certainly.

[Christoph]

Nice! Stoked.

Going to pick it up in a couple days

Do you know if the BVM-20E1U has an input board with a SCART connection available?

[Fudoh]

No, but the stock connection already accepts RGBs through BNC.

Hello all, what is the opinion about modern plasmas for emulation? I think still there are some monitors made by Panasonic

I ask because some say it might be the last year of plasma production

[beharius]

We have that Pioneer PDPV402 beast for more than a decade(13 years?) and it's still running great. It's left in one of the rooms and not used for a while.
I just checked its service menu and it's 13249 hours. Amazing performance, brilliant colors, it just lacks black color. I recommend to play Dreamcast over its VGA. Both 15khz and 31khz modes supported. I also check that RGBS works well on its HD15 VGA input.

Thanks Fudoh for reminding me that display.

I am currently using Panasonic TH42PWD7/TH50PH6 for gaming and Pioneer Kuro 60" for movies. Panasonic is great for retro gaming too...

[Fudoh]

Just a matter of having a little patience...

[ryu]

you gonna start hoarding these?

[kamiboy]

You better spread the love.

Qq: recently picked up a 20" Sony pvm. According to manual it has sync on green or separate BNC sync input. I plan on using SCART to BNC cable + consoles with SCART cable. Do most consoles support sync on green or should I be using separate sync input?

[Fudoh]

There's not a single console which supports RGsB in 15khz mode.

[Magicalbottle]

Can someone let me know which of the following the best choice is for a PVM?

PVM-20M4E
PVM-20M2E
PVM-20N6E
PVM-2130QM

Which are the newer sets? And what are the main differences? I think the QM has a scart, the rest don't. I also read I would need an ohm-resistor or something, I thought these were plug and play with RGB cables?

PVM-20M4E

[Ed Oscuro]

BNC connectors are fine. If your cable has a SCART-style adapter, you can still probably just buy a SCART-BNC adapter and use that.

I'm not sure if SCART plugs are actually a positive thing for our uses, if you get confused between the rare (but sometimes still seen) JP-21 RGB pinout and a SCART plug - the two aren't compatible and there is a danger in using the wrong types.
