24" Widescreen CRT (FW900) From Ebay arrived,Comments.

I'm looking for a table telling which S-capacitors are used for which horizontal frequency ranges for the FW900 / 21" variants. That's an array of film capacitors used to correct the sweep speed of the guns so that the center and the edges of the display are of the same width.
I found a description of the circuitry of the G1 chassis (21" variant), but they remain extremely evasive on that part.

Did anyone step upon that kind of information ?

The problem is to know if the issue really comes from a faulty FTB. It could well just be a cold solder joint (very likely for intermittent problems) or any peripheral failure that has nothing to do with the FTB itself.

Uncle Vito should still have FTBs for Sony monitors, but as far as I know he sells them with the entire D board, and the price may be quite high.

edit: BTW, when you say losing focus, do you mean a brief (half a second) focus loss with the display area decreasing and a spark gap activated, then everything coming back to normal immediately, or something else ?


We have FBT in stock as the entire D-Board. PM if you need one...

Sincerely,

UV!
 
Some may remember the damaged track I repaired on the N board of a FW900. Here is episode 2.

The repair didn't hold. The display could retract vertically and I often has to spank the screen to fix it. The solder under the memory chip wasn't good enough, but I can't remove it. It's not very safe to play again with some pads that chip is soldered on.
So I called in McGiver's spirit. I removed the lacquer further on that track, stuck a thin electric wire with duct tape between that point and the next solder joint, and soldered it. It will hold now. :sour:

Well ladies and gents, finally got my first LCD monitor in a long time. Reason for purchase was that I wanted to code on it and I didn't want to waste my precious CRT's on what amounted to displaying office stuff. Enter the Viewsonic VA2265SMH. So far I have to say that I'm very impressed by its image quality. Measured contrast ratio was 3033:1. Grayscale tracking is dead on (I got about 0.2 dE on it simply by reducing the green down a couple of notches - more on that later). And primaries seem to be pretty close to Rec 709, so nothing looks incorrect. Out of the box, it was pretty good. I didn't measure all of the modes, but User color mode (with Red, Green, and Blue jacked up to 100% each by default) produced a dE of 2.8 at the worst (100 IRE). Once I dialed it in though, it was perfect.

Not all is pretty though. It pretty much falls apart whenever you try to game on it. Admittedly I have it on an old DP-to-HDMI port that can't take advantage its maximum mode of 1920x1080 75hz, so I'm stuck at 60hz. But even then it looks like ass. Motion blur is pretty bad, even for an LCD. Lighter colors are okay, but darker colors are a mess. Still, I didn't buy this for games. I bought it for casual use, and for that I cannot fault it. For an every-day user, this thing is great. For its price - $112 shipped on Amazon when I bought it - it's even more amazing. I'll update once I get 75hz going because who knows - it may improve the situation. But so far - I definitely like.

EDIT: Update - got 75hz working on the monitor and it marginally has helped things. I still wouldn't recommend this for gaming, but everything else looks great. I think that if there's a gaming VA monitor that delivers this kind of image quality but with good motion clarity and response then these monitors could be CRT replacements (sort of - nothing can really replace them :D).

I hope its okay to post it in here first

If anyone is interested in a great condition, 2003 FW900 in GERMANY feel free to write me a PM.

What Gau or Komissarat? Near former Ostland-Lithuania or Ostprusen?
 
thanks for sharing those thoughts jbl, always interesting to hear stuff like this from long time CRT users. And I like your strategy. Save the CRT for when it counts :)
 
I used that strategy in the last 10 years with my FW900,but i use other CRT even for 2d because i hate LCD and that fucking blur while scrolling web pages.
 
Has anyone tried using their monitor with the nintendo switch?
When I first got the system I remember playing Zelda on the Sony FW900 at 1080p. It's been a few months since I tried playing the switch using this monitor but I tried it again and it locks to 480p. My first thoughts was maybe the cheap adapter was the issue but I'm not so sure.

It's working for me via an HD Fury Nano GX on the latest firmware. I don't have any other adapters to test.
 
I have been one of these sitting in my attic that I want to get rid of. What is the best way to get rid of this monitor? I don't wanna throw it away, and I spent good money on it, but it's just collecting dust in the attic. Ugh!

Having someone come pick it up locally is your best bet. I'm sure there are lurkers here who will be happy to take it off your hands.

I'm in Eastern Prussia, Masuria. I'd take it off his hands, and his car, too. But can't afford a train ticket.

Seriously though, the pictures of your screens are stunning. I still have both an LCD and a small 17" CRT. The CRT is so slow at heating up it takes 15 seconds to even show a picture, but I still rule at FPS games with it.
 
Hey. For some reason I can't send the message to you so I'll write here. Where do you live in Germany and what's the price for your monitor? Thank you.

i can't send you a pm/start a conversation either, maybe because your post count is too low?

Anyway, i am located in northern bavaria and was thinking about 150€

I'm leaving for China for a few months on Friday. If anyone wants to drive to Allentown, PA (Wednesday or a Thursday) and pay me $20 (it is a b*tch to move down two flights of stairs, so consider it a moving fee ), it's all yours. I have no idea the condition. I bought it maybe 10 years ago and it's been sitting in my attic ever since. I know it works and turns on, or at least it did when I got it.

If you can't make it this time, I'll probably be back in February.
 
Paging thread for an update on that digital to analog adapter... :)

I tried to find a software for dump the firmware of the adapter end edit the registry settings, but Delock told me that Analogix doesn't have it.
Looking better the chipset datasheet i saw that the only voltage which can be modified have nothing to do with the digital and analog power,which is the 3.3V 0.5A of the DP source,i don't know if the power is the limiting factor of the pixel clock frequency or if simply the chip can't do more,on datasheet i see a power consumption of 624 mW at 1920x1200 60Hz
I tested the adapter on a AMD 5850 and it worked very bad,probably the DP lanes configuration made for HBR2 mode,so it need at least a DP 1.2.
I did some experiments with reduced blanking (for now only horizontal),i looked the VESA documents (GTF,DMT,CVT) and after some tests on 3 different monitors i noticed that the fastest is the one in which i can reduce the blanking more without compromising the quality of the image.
Is there someone expert on this argument here?
The goal is to reduce the total blanking under the VESA timings without compromising image quality (taking into account the 340 MHz limit of the adapter)
This is very difficult if not impossible using the eyes,so if someone with a colorimeter want to do some tests,the VESA documents explain all things.
Set 2048x1536 a 75HZ,339.19 MHz with CVT timings,try to reduce both the horizontal and vertical blanking and see how many MHz you have recovered.
On the FW900 service manual i see this:
* Recommended horizontal and vertical timing condition
• Horizontal sync width duty should be more than 4.8% of total horizontal time or 0.8 µs, whichever is larger (here VESA set 8%)
• Horizontal blanking width should be more than 2.3 µsec. (Diamond Pro 2070SB here is 2.016 µsec st 2048x1536 85Hz)
• Vertical blanking width should be more than 450 µsec. (here VESA uses 550 µsec)

I am in the market for a loaner Sony FW900, a Sony GDM-W900, Nokia 445pro, Electron22Blue, (or a rebrand of any of the above models) for a specific experiment at Blur Busters.

The higher the horizontal scan rate & vertical refresh rate, the better, though it doesn't have to be the world's highest scanrate CRT.

Blur Busters is located in Hamilton, Ontario, Canada. So the monitor must be located in the Toronto/Hamilton area. I have car transportation for pickup. Reimbursement will be provided for a loaner (or possibly, purchase).

Please inquire within mark[at]blurbusters.com

Thank you!

You should also be on lookout for later Diamondtron-based monitors. My LaCie Electron22blueIV can hit a 140kHz scan rate, which is higher than the FW900 I think.

That one is good, and also suitable too. I'd take that as a loaner, too if you were in my area ;)

A very high horizontal scan rate, combined with a good high vertical refresh rate, is very favourable.

(Still, I am very interested in the widescreen Sony's simply because it is famous, and is still above the minimum scan rate criteria I need for an experiment.)

One interesting detail I can notice is that it features a ferrite core. It's the first time I see that on a VGA adapter.
 
Ferrite beads are used on most vga cables. Analog signal is susceptible to electricity from cables nearby.
Guys... being tired of lcd monitors, is there any way I can go back into crt dream and make it look ok on my Ikea mal desk? Lol the weight of crt alone would make my desk crumble if I could ever get one. My biggest regret is selling my 17inch Eizo crt I had back up to 2004.... man...
 
I know what a ferrite core is used for. I just noticed there is none on all the (crappy) displayport/HDMI -> VGA adapter I've seen so far. ;)
 
The weight issue isn't actually a thing unless you use a cardboard box as a desk. Even the FW900 is only 100 lbs soaking wet. A bit bulky for sure, but really not that heavy. No problem for any desk worth its weight in sawdust. Your best chance at getting a CRT would probably be finding one locally on Craigslist, Ebay, and the like. Check here as well:
 
They're still the kings of the monitor race, what can we say? There is still no "everything is better" upgrade option for these things. Any way you go, you'll be comprising in one form or another.

Edit - glad to see you stop by! :D

If YOu only were living in Poland - I would get on this shit :cry:
 
Delock told me they have already received the first shipment of the adapter and they sell it now,so it should be available in stores in a short time,at least in Europe
 
Well,the adapter is on Delock homepage,it is aesthetically different from my sample,it seems to be built with better quality,i hope it works well.
When the USB-C version appeared on Delock home,after two weeks it was on sale,maybe even this time.

Delock 62967
http://www.delock.com/produkte/F_1287_Displayport-Stecker---VGA-Buchse_62967/merkmale.html

Weren't they supposed to have 340MHz Clock? That's kinda saddening, 270 Mhz is quite far from 323Mhz required for 1200p @ 96Hz. Waiting for tad faster adapters...

If YOu only were living in Poland - I would get on this shit :cry:

Tracking this thread few years back it seems that Poland has to have one of the biggest CRT fan base around the globe, me included :)
 
The datasheet of the adapter just reports the specs of the Analogix chip it uses, that doesn't mean it's limited to a 270 Mhz pixel clock ...
 
I thought I was clear with the chip specifications,i don't know if all the chip can do 340 MHz and clearly Delock can't indicate that speed on specs,what we know is that two sample with the same chip (because 9847 is 6212 for dongle) have reached from 340 to 342 MHz.
Maybe some chip can do 344 and others 338,but don't worry 322 MHz is easy.
If it breaks at that speed only time will tell,my sample for now is all ok,I did not keep it at 340 for hundred hours,but some good playing time at 2112x1320 85Hz without problems.
Sorry i don't have the power for such resolutions and in the last weeks i played most of the time at 1680x1050 100 Hz.
I have a question for those who have bought the vcom converter,how is the video quality compared to the native DAC? (specify if with AMD or Nvidia)
Another thing,if you like downsampling with CRT don't buy AMD cards,it is a pain in the ass.
