Fudoh's ode to old display technology

[danielretrogamer]

Never seen a pro CRT bigger than 20" here in Brazil, and probably would be $$$ as hell if I found one.
For a bigger screen I'd save money and just go with a regular 29" WEGA TV, but that's just me.
I know the picture is not nearly as good, but here they go for 1/10 or less of the price of a (smaller) SONY PVM.
I think 1 20" + 1 14" (TATE) is good enough for me, even though I have more monitors at the moment.

Anyone got pictures of a PSP on a SONY PVM/BVM?
I am considering getting one soon.

Oh, another question: The seller has a 1942q for sale. This model apparently takes 'Digital RGB' in, which looks like a VGA connector. The manual doesn't specify the operating frequencies, so does anyone know if this'll take VGA output from a laptop?

[Guspaz]

No. Wrong connector, wrong signal, wrong timing.

No, but you can use it with an old PC with a CGA or EGA card or a Commodore 128.

That's what I thought, thanks!

I think I'll pass on this monitor and wait a bit. Thanks!

[Einzelherz]

If you're looking for something that will accept VGA, why not just get a PC monitor?

[Xyga]

Fun fact: there's still a fairly large number of TVs with a VGA input being released, even over 50+ inches, all from lesser known/popular name brands though.

Hey all, I've got a BVM 20G1U that has about 11k hours on it.

It's got a *very* slight yellowish hue happening on a pure white screen in the bottom right corner.

I've tweaked the geometry but nothing else. Any thoughts on how to address this?

I'm probably going to get it rebuilt early next year, but I was just curious. Thanks!

Like reduced brightness output, a yellow tint may be a symptom of CRT aging (phosphors deterioration). Apparently blue phosphors degrade earlier than red and green - white is made by combining all three primaries, and it turns yellow when the blue channel is lacking. You may be able to fix this by adjusting the balance between the primaries. See here: http://wiki.diyfaq.org.uk/index.php?tit ... olouration

That said, I don't know if a BVM may exhibit such issues after just 11k hours. Did you wait for the tube to warm up before reaching this conclusion? Also try to adjust the brightness and contrast settings as well if you haven't already. You can do it manually with Artemio's 240p test suite.

Edit: Actually, I guess BVM's will have test patterns for all your calibration needs.

They only have black and white test patterns, so you can mess with brightness and contrast, look for any convergence problems, etc., but not a single color test pattern (like the common NTSC test bars you would think it has!). At least my 14F1U and D20F1U don't seem to have them on channels 91-99.

Duh. How long should I wait for it to warm up?

[ChuChu Flamingo]

The usual recommendation is 20-30 minutes.

[Einzelherz]

Fun side note: my stupid Viewsonic XG2401 LCD monitor takes longer to warm up than my CRTs.

[Charlie97L]

Not nearly as bad after I let it warm up.

Still a bit disappointing, but I don't notice at all during gameplay. Gonna mess with the settings too.

Hello everyone. I wanted your help finding a good crt, I only have pal ones here, and I wanted to know how do I know that the crt I'm buying is SD and not HD?

HD CRTs are rare as hell. Usually you'd know if you're buying one. If they don't mention anything, it's gonna be SD. Go for a PVM, if you can.

[KatKya]

I've heard it's relatively easy to happen upon 100hz sets in Europe, though I admittedly don't have any experience with that.
That said, at least in the US, they're more than common enough for someone to accidentally happen upon a Sony HiScan model without realizing it, and those late Samsung HD models seem to be at least somewhat common as well.

Have some problem with a french n64 rgb on a ikegami 1990r (work on my jvc dtv, sony bvm or ikegami TM20-80RP) seem a sync issue, but other console like snes and ps1 work without problem.
The scart to bnc is with sync stripper.

Hello there,
I just connected my Wii to my PVM-1442QM with the original nintendo rgb-cable and the standard euroscart to BNC cable by retrogamingcables. The picture looks just fine, no distortions or so but it is just red. What could cause this?

Best regards

The video looked like it could be caused by bad capacitors, but you said it works with other RGB consoles, so I doubt thats causing the problem. Not to say the monitor doesn't need a recap though!

I have a feeling the issue is with the RGB mod in your N64 – is it a standard mod? I assume it isn't Tim Worthington's RGB board?

Does disconnecting each color separately have an effect on the display?

If I understand you right: I just disconnected the RED-Cable and it shows a dark picture, with a little bit of greenish stuff to see (the WII menu in general is pretty white)
I then reconnected the RED-Cable and removed the GREEN one, it shows a picture but with the heavy red tint just like it look like when all three cables were connected.
Last but not least I turned the monitor on using only the red and green cable, same red picture like before.

I also noticed that the official nintendo rgb-cable has only a few pins in the euroscart adapter, quite a few are missing, does this have to mean anything?

Would this be a PAL or NTSC Wii? Only the PAL model outputs RGB so if it's NTSC you'll likely be getting YPbPr out which could well result in an image of some sort but with missing colour channels resulting in the symptoms you're describing.

Just a wild stab in the dark, I could very well be jumping the gun on this one.

Ohhh, I actually have a PAL Wii but your post made me think and you know what? For whatever reason I must have changed the video output of the Wii to ntsc years ago when I was playing around with homebrew. Changed it back to PAL and now it works!

Thank you very much for pointing me at the right direction!

yes , was done in 2013 (kit buyed from a french website) the problem is only with the 1990r, the 64 work without problem on other monitor.
and the 1990r is manifactured in 2009 so the capacitors are not really a problem.

That looks really really nice. I happen to be picking up an Electron Blue IV in the morning for the exorbitant sum of £15. I have an Extron DVS 510 for upscaling to 31khz but unfortunately no scanline generator Still, it'll do well for Dreamcast VGA and pseudo-15khz output from my PC for the time being.

ETA: Forgot about Wii, I have a VGA cable for that too

fantatic 4fxtwin! I hope you enjoy it. yes an SLG or other such device relly gives 240p titles that PVM/BVM look. (i'm using an old school line doubler for this, so no input-lag. but i'm intrigued by your Extron DVS 510, how does it handle 480i content?)

since you mentioned the WII you can use retroarch and its inbuilt scanline function for a very nice a 240p scanline style on retro games. the only quirk is the default scanline pattern needs a little adjustment as most NTSC games register at 244p instead of 240p so I made separate folder with my own scanline patterns on the SD card (let me know if you would like an upload).

but after that RA and native Wii (and gamecube) titles look fantastic on the Electron Blue IV in 480p. I also enjoy all the 480p original Xbox and PS2 titles on the monitor as well. and a good amount PC titles in 1080p or 2560x1920p with 4:3 aspect ratio support. I also have an nvidia android system hooked up for media purposes (as well as a few android games) and it's a treat to watch movies and TV on the Electron. take some pics if you get a chance!

Ooof... that SoR pic is nasty(in a good way).

That's like hardcore CRT porn, lol
