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

Well,it seems that someone is interested to make an adapter with the Analogix chipset,i will inform you when i will have more informations.
Analogix is only a chipset maker,is the chinese manufacturer of the adapter that fucked us.

Awesome.

So do you guys think it would be possible to manually overclock these things to go higher than 400mHz?
 
Personnally I would think myself very lucky to have an external displayport -> VGA adapter that reaches the 400Mhz of internal graphic cards DACs. Not even talking about picture quality.

Going above is really (too ?) ambitious.
 
Well the DAC's on our video cards (that support VGA) can actually go above 400 with Toasty X's tool. So I don't think it's too ambitious, I'd like for it to be as high as possible, especially considering that even a 360mhz cap will limit the range on most 21" CRT's.

That's great news! On my side, I'm still looking for both the ANX6212 and ANX9833 chips pinout. If these ICs were ever sold new on the market, these informations should be public knowledge, and should be readily available from the datasheets. The only documents I can find are the "product briefs" on Analogix website. That's weird.

If anyone here happen to find the complete datasheets for these, I'd be really interested.

Yes but, the DAC in external adapters and internal graphic cards aren't the same. You need a good, high frequency DAC in the first place. Then come the power consumption and heat dissipation issues, which may be a limiting factor or at least a design annoyance with adapters in the usual form factor.
 
Look this:
https://www.paradetech.com/products/ps8611-dp-to-vga/
a chip from 2009
4 lanes HBR total bandwidth 360 MHz 24 bit (DP 1.1a)
DAC 250 24 bit
It says NOT RACCOMENDED,use our updated product.
The updated product would be the PS8617:
two lane HBR,DAC 170 MHz,1920 60Hz bla bla bla
Instead of moving forward they go back
It seems no one wants that analog output puts more than 1920x1080 60Hz
 
Here https://wenku.baidu.com/
i found the datasheet for ANX9832 and ANX9837,the pin diagrams are very similar exept for a few pin,but the two ic have different functions.I think that ANX9833 and ANX6212 are more similar between them.
 
Haven't been here for quite some time, I was really interested in Analogix. By the way I got second FW900 with scratched AG and mine polarazing foil is just too dark. Will have to look for something less light absorbing.

UNKLEVITO if that is not a secret, when was the last time people like directors bought CRTs from you? I guess they might have been popular around 10 years ago, but are there any influential folks still using them?

Hey, long time lurker from Poland here.

Anyway, I'm selling my FW900. It's a unit from the first batch(oct 2000) and it's 100% functional. Could use some windas/focal point adjustment which I've never gotten to though. The coating is intact and the only visible scratch requires a bright static image to be seen.

So any polish and german people as well since I live near the border(150km from Berlin) are welcome to PM me.


Got a Mitsu DP2070sb as well.



EDIT: I've changed my mind and decided not to sell them yet. Feel free to PM me with offers though.

Z ciekawości, gdzie i jaki przedział cenowy? Możesz zrobić dokładniejsze zdjęcie rysy?
 
I have the coating issue on my "to deal with" list. I already got enough technical informations about it a few months ago (it's somewhere in this giant thread), I just need to pick my FW900 with a damaged coating and take brightness measurements with/without coating to confirm the data.
Then there's a US company that can make custom films, I'll contact them to see if they can do something. Of course I'll keep you updated when this happens. I just can't say when I'll have time for this. ;)

I am in the DFW area, and I have a working one of these that I originally had shipped from CA for the low sum of $950 or so... and yet it is sitting here on the floor of my office collecting dust. It DOES need a windas adjustment, but otherwise it works fine. I don't have it in me to send it back to CA for adjustment, but I also don't want to just pitch it... Anyone in the DFW area want to just swing by and grab it? If you promise to actually use it and fix it up, I would happily give it to you, but I would want a picture of the "finished" product after the adjustments. It is the gray fw900 made in January 03. It needs a good caring home.
 
Can anyone recommend a DAC converter that will handle 1024x768 @105hz. This is the resolution i run my Hitachi Superscan Pro 21 at, I have held off upgrading my GPU until a good DAC arrives. At this low resolution should i be okay, even at higher hz?

BTW, I used to own two F900's (a7217a's precisely). Foolishly sold them for $300 each a few years ago, still regret it. Hitachi is nice for its age (1996), but no substitute for the FW900...

Any converter avaible will do the job. Most of them have a 165mhz cap, so I suggest you to go to your local ebay and get the cheapest one (in europe you could get them for ~5€).
I'm using right now one of those at 1280x960@95hz, really happy with it.
 
Mmhhh I think there is some confusion. If we already knew good adapters hitting 300Mhz, it wouldn't be such a necessity to find new ones.
 
Why limit yourself to 1024x768? HD Fury Nano GX and the VCOM displayport adapter can hit fairly high pixel clocks, close to 300mhz
My monitor can't do 100hz at any higher resolution I don' think or I would run a bit higher. I'm okay with this resolution though, its easy to pull 100+ FPS is any decently coded game. I should have waited for the reply here before buying an old gtx 950, I wish i had gone for the 1070mini or 1050ti in my mini itx build...
 
Would it be better to convert from DVI-D to VGA or Displayport to VGA?
No difference in quality, but I would chose the displayport because dvi is already dead.
Im quite sure that your monitor is capable of higher resolutions, could you post the exact model? Sounds like you are only using the monitor presets. Download CRU (Custom resolution utility) to enable 100hz at higher resolutions.

Actually I think the analog signal is gone on the GTX 1000 series, you would need a GTX 970 or 980.
On the AMD side, the best card which still has an internal DAC is the R9 380X. There's also a R9 380 4Gb made by Sapphire in the ITX form factor, it's slightly less powerful but it can be found quite cheap. I guess it's a way to get rid of the remaining 380 chips they had in stock.

Its a "Hitachi SuperScan Pro 21" model number: CM211OMU. I could hardly find a trace of info, but one .pdf I found online had an ad listing some supported resolutiosn 1024x768 @105hz being one of them

That's just a recommended resolution. I can run my 19" Trinitrons at 125hz with 1024x768. So I imagine your 21" could go much higher. Just use CRU to add whatever refresh rate you wish. If it's too high, your monitor will tell you "out of range".

In that case I'm sure you're going to be able to run higher resolutions&refresh rates. Once you have everything set up, download CRU and then;
1st: On the detailed resolutions box click "Add"
2nd: On the pop up window, select timming "Automatic- Crt standard" and input the resolution you want at the refresh rate you want. Using a gtx1060, you're going to be limited to the pixel clock of the adapter, most likely 165mhz, so don't surprass that number or else you'll have problems or directly no image.
3rd: Once done, press Ok to close the box and ok again to close the main program.
4rd: Restart your pc, and you're done. You will be able to select the new resolution in windows and any game. If you wanna make that resolution the default one just move it to the first position on the "detailed resolutions" box of the cru program.
What kind of games are you planning to play?
 
have a bead one on buying one of these, anything I should know before buying it? And whats the easiest device I could get to test it before taking it home? (Craigslist.) I think the only computer I have with analog video out is my big desktop.
 
Hello hardforum CRT masters.

I was going to sell/toss my Sony F500 but I decided to get an hdmi to vga adapter and hook it up to my playstion 3. So I set it up and I have a question; Should I be using full range (0-255) or limited range for the hdmi output. Full range seems a little too dark for films and some games, even after turning up the brightness (my sweet spot is 35 brightness), while limited is far better and doesn't really look washed out.

In my understanding, always use full range with CRT's. What adapter are you using?

If the seller is selling it for a good price, it might be worth the risk, especially if they vouch for its condition and you trust them. But no harm in bringing your desktop there or asking them to set it up on their computer to test.

can you set the playstation 3 for full range?

I am using a J5Create HDMI to VGA with Audio.

Yes I can change the settings between full and limited range. Full appears to be too dark. Limited still looks great, better than my current PLS lcd monitor.

you're changing it to full on both PS3 and your video card settings right?
 
right, but what I'm asking about is the playstation settings themselves. According to that link I posted, it looks like you can set the RGB to full on the playstation itself.

Yes you can set it to full or limited under settings > display.
 
ok, so you've set your ps3 for full. And in your video card settings too I assume (nvidia control panel assuming you're using Nvidia).

So you've set full RGB in two different settings (one for ps3, and one for video card)

If both those are set to full, then I don't think there should be a problem, but I have very little experience with this particular issue.

One thing you might try, to see whether the darkened image is due to poor gamma or because you're actually crushing levels in the signal pathway is to try to get a test pattern on the ps3 that has shades in the lower region, and see if they're distinguishable at high brightness.
 
Yeah, you're absolutely supposed to use Full range RGB. My guess is your Nvidia card is outputting limited, and you set brightness for that. Then when you go full on PS3, you're getting crushed blacks. You need full on both.

My advice is to go to http://www.lagom.nl/lcd-test/ and download some of the images and put them on your PS3. Stuff like black level, white level, grayscale gradient. Then adjust your brightness/contrast with the PS3 set to full range. Then also make sure Nvidia is outputting full range RGB. Then results should be the same on both PC and PS3.
 
oh, I see, the ps3 is connected directly to monitor. So no PC video card to go through.

maybe it's just a gamma issue, either the crt isn't well tuned, or gamma/brightness on ps3 is off?

I'll probably mirror them on the CRT (ps3 only, not hooked up to pc atm) and LCD and try to get them to match.

My pc has a GTX 660 ti with DVI-I so I've never needed to set my black level while using the crt with my PC. LCD I have to reset every time I clean install the drivers, which is normal. (LCD hooked up via HDMI)

Yeah its an old CRT, still works good but CRT's just dim a bit over time. I think I still have the cables and software for a G2 calibration if needed. Lotta work though lol.
