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

Tried connecting F520 to a different computer with Windows 7 and GPU with analog port and it is still reported as 220MHz...but - I can actually go upto 400MHz resolutions there - it just works. So I was thinking perhaps the Sunix adapter reads 220MHz from EDID and hard-forces this limit somewhere instead of just "letting it through" like Windows 7 just did in my test.

I have been manually playing with EDID in Windows registry as well (to get at least a little familiar with it), changing the relevant byte for pixel clock, but something just overwrote it back when I restarted video or PC. So I removed permissions from everyone to prevent any modifications of this entry and it just resulted in some BAD_EDID error shown as the registry entry name and no cigar.

I wrote to Sunix about this, perhaps I can get a reply from them :)

What are your EDID reported pixel clocks by the way? I dont remember what it was with my FW900.

On analog AMD cards you can use Toasty X's pixel clock patcher and remove the 400mHz limit. Not sure about Nvidia though. Kind of moot now that even the best analog cards are on their last few years of relevance for modern games.

The Sunix adapter is just passing through your monitor's EDID to the GPU. The problem is on Microsft, Nvidia, and AMD's end, specifically when dealing with displaport connections or displayport splitters.

On my LaCie it's 420mHz, on my Dell P992 it's under 300 I think. Though at some point I'll be getting an EDID spoofer and I'll try to set it to 600 or something.
 
Need help with my Sony fw900 I had it stored at my mom's for about two years. She had it on her porch covered. I recently took it home and I connected it and it doesn't turn on it only has a solid orange light on the power indicator. What does that mean when it's orange? There is no clicking or post. Any solutions?
 
Solid orange should mean it's in standby mode. If you don't even have the white/red/green/blue display there's a problem. Try powering it off/on several times, try slapping the side of the monitor, see if that helps.

But honestly, if I understand correctly and you stored that monitor outside for two years, even covered, that was a pretty stupid move. Moisture may have gotten inside, and temperature variations, especially negative ones, are pretty bad for electronics. Who knows the effects this has had on it.

I know it was a stupid move. Mom didn't wanted it inside her house lol. I will try turning it on and off. I did have a feeling it might have been the temperature variations. I hope something works if not then I'm screwd.
 
The problem is that if there's a failure it's not one happening in normal conditions use, so it may be harder to find out what's wrong, and/or it may be a kind of damage that cannot be repaired. But there's a reasonnable possibility for that screen to be repairable.

A couple of potential issues I could think of:
- General moisture (having it covered doesn't protect it, unless it was enclosed in an hermetical bag). Any sort of smell giving a clue about this ? The obvious thing to do is to let it dry but if it remained somewhat wet for a long time there may be some damage, visible or not.
- Bad solders (may have happened with wide temperature variations, especially if some were already substandard)
- Damaged electrolytic capacitors (bulged or leaking).
- Oxidized connectors

Checking this requires to open the monitor and at least to inspect the boards visually.
 
Wow, the Sunix DPU3000 is out of stock on amazon, the current adapter I'm using doesn't have a high enough Mhz so there's green artifacts all over the screen. My USB-C port is already in use, what to do...

Check out this post from Derupter :

https://hardforum.com/threads/24-wi...ived-comments.952788/page-413#post-1044237251

He believes this adapter could have the same range as the Sunix. You could maybe be the guinea pig for everybody and let us know how high it can go?
 
Well crap, got a 5700xt, and turns out AMD doesn't support custom resolutions with the Sunix nearly as well as Nvidia.

It seems most of CRU's overrides aren't working, like 1024x768@160hz isn't showing up from CRU, Can't create a 1920x1440@90hz resolution for some reason, even though it has a similar pixel clock to 2048x1536@85hz. 85hz worked fine. Any resolution over that is restricted to very low refresh rates. Doesn't support interlaced resolutions over either HDMI or DP, when Nvidia still supports them over HDMI.

Don't know what to do. I guess I'm going to buy something to spoof EDID externally and hope it opens up some possibilities.

Thanks for the warning. My memory is fuzzy, but I think people in this thread were having some issues with newer AMD cards earlier as well.

Good to know. Did you try setting the custom resolutions in Radeon settings ? It allows to do that now so maybe CRU isn't needed anymore or that function interferes with CRU ?
 
Yeah I tried radeon settings but it seemed to be limited to the same pixel clock ceiling as CRU at higher resolutions.

Though I was able to add 1024x768@160hz in radeon settings when I couldn't in CRU. So yeah, there are some other weird limitations that I don't understand yet.

I'm going to send messages to AMD support to see if they can fix some of this stuff. Though I'm afraid to mention that I'm using a CRT because they might automatically trash my request.

Interesting thing is that I was just using a 380x which has analog out, and I was literally able to send 4k over the VGA connection, after using ToastyX' s pixel clock patcher. So this is an HDMI/display port issue.

Strat_84 are you hitting any limits in Radeon settings? Have you been able to get near or above the max pixel clock for you CRT reported in CRU?
 
Well, I didn't experiment with Radeon settings so far. It's not necessary as I'm still using a 380X graphic card, with rather standard resolutions/refresh rates. ;)
 
Well, since my motherboard has 3 pci-e x16 slots, I put my 380x in a spare one. Good news is you can play any game in borderless windowed mode from the main GPU and output it on the secondary GPU. This left open the full range of resolutions from the 380x, including interlaced. Bad news is borderless windowed: it has an extra frame or so of lag. So for casual single player games, it's fine. Also best to hook up to a pci-e slot that doesn't share lanes with the main gpu.

Then I tried with a less power hungry HD 5450, but it's old and on legacy drivers, so I couldn't install both at the same time. Maybe with some registry tweaks and some Device Manager tricks? I dunno, I didn't feel like messing with it anymore.

My next experiment will be to hook up an Extron 101v to a 4k TV, copy the EDID, then use with my 5700xt. That will probably get here tomorrow or monday. EDIT: Did one better and programmed a dummy plug with CRU + edid-rw. See next post

So I played around with some spoofed hardware EDID's.

TLDR: The resolutions on the hardware EDID work as normal, no pixel clock limit, but I'm still hitting a ~350mHz limit from AMD's custom res utility, and anything I put in CRU is still ignored. Maybe AMD is recognizing the Displayport device as a splitter, which "officially" max out at 2560x1600@60hz (sunix specifications)?

Anyway, here's how got a different EDID to the GPU:

So I reprogrammed a dummy HDMI plug with linux utility "edid-rw". Pretty easy to do, since you can just export a BIN file from CRU. I just had to delete a couple extension blocks since the dummy had 256 bytes memory, and a full size EDID is 512 bytes.

After that I hooked up the dummy plug to an Extron 101V, which saved the EDID. Now I just run my Sunix to the 101V, and the 101V provides the EDID while passing through RGBHV.

If you don't have a passthrough device like the 101V, you could also put them dummy plug on a active or passive splitter. You just have to make sure the EDID signals from the actual monitor aren't getting to the GPU, only the dummy. So snip ID wires, use a 5 BNC cable to go to the monitor, etc.

edid-rw could also reprogram the EDID on your actual monitor if you wanted to, but sometimes they're write protected, which then requires snipping a pin on the ID chip

Thanks for those suggestions and sorry I haven't been able to get back to you guys. Well guess what friends? It works now it was so dusty and it had some sort of sticky residue. I cleaned what I could and then it turned on.
 
Well i'll be damned if a fella isn't a monkey's uncle!!! Well i was watching some videos on youtube again my video shak-y-eir than Michael Jay Fox playing Zoro AS USUAL. And i got the notion of interference based on my recent purchases vs when this CRT started shitting the bed! Turned off my air purifier under my desk and the shaky vision STOPPED DEAD!!! Good ol picture as usual!!! All i need now is to dial in color! 2304x1440 @ 79hz!

Here's what my picture looked like before

So was it a power issue or moisture/air issue? You're the guy in Texas whose AC broke down too, right?

Can be a problem with the Displayport link rate.
Radeon Settings -> Display -> Specs -> Current Link Speed:
if you see 2.7 Gbps x 4 you are on HBR and max pixel clock is 360 MHz
if you see 5.4 Gbps x 4 you are on HBR2 and max pixel clock is 720 MHz
The problem is that it shows the current link based on the active resolution,so example you can see at 1600x1200 100 Hz:
2.7 Gbps x 4 or
5.4 Gbps x 2 (if it shows this then there are no problems with HBR2 and the problem is elsewhere)
Eventually you can try with another displayport cable or connect it to another port
 
So was it a power issue or moisture/air issue? You're the guy in Texas whose AC broke down too, right?
As far as I understand it was his air purifier device that was either emitting EMIs affecting the display, or sending noise in his AC line, and that noise made throught the FW900's power supply.

Ney, Missouri, it's some kind of interference from the fan in the air cleaner/filter. i get a lot of dust and shoved a levoit air purifier under my desk to help circulate clean air when running all my electronics, guess that didn't do much since i have to turn it off to enjoy my CRT. :-/

BTW, since the CRT is so long i moved my desk closer to me and away from the wall with a big gap and the CRT's back hangs over said gap, give me more desk space and a space for the air to move a bit more freely. The Filter sits down below and blows air up through that big gap. maybe i might try another model of air cleaner.
 
You know what relay sucks about owning a CRT?
when it has a odd ball tube you can't find specks on to rejuvenate or have a plug for so you have to use a pig tail an hope for the best.
I have a Mitsubishi CRT that is super nice but its dimming :(
 
CRT repair is becoming more popular on youtube, maybe you might get lucky with a bit of info?

Actually, it seems that everything in CRU, regardless of pixel clock, is ignored. Yesterday I checked on my dad's 380x PC, hooked up via HDMI to a TV, and it seemed to be ignoring CRU as well. Either EDID overrides are broken, or intentionally disabled. I'll submit a query to AMD support and see what's going on.
 
Hey, since my fw900 is working again why am I only getting 1920x1080? Could it be the different hardware I'm using? I'm using windows 10.The gpu is a bit old it was never tested with this monitor until a few days ago. It is an Asus R9 390x amd graphics card. I mostly use for gaming such as Apex legends. In the past I used to get 2304x1600 or 1920x1200. Any idea's?

are you sure its the FW900?
You may have to load a driver or make a custom res in you gpu drivers panel. I have to do that for my crt.

Yes, I am sure it is the Fw900. I have tried creating a custom resolution with Amd display settings but it says the monitor is not compatible with that resolution.

If I remember well the R9 390x has digital outputs only right ? So you're now using an adapter whereas you used to plug the monitor directly on the graphic card in the past ? In that case, the adapter is probably the reason of your issues, 1920x1080 is the standard resolution they are usually set to as a default.
Try setting a custom resolution with CRU if AMD display settings doesn't work.

Yes, That card only has digital outputs. Im currently using this adapter which I bought a couple of days ago. https://www.amazon.com/CableDeconn-...n+dvid+to+vga&qid=1568142715&s=gateway&sr=8-7. In the past I used to use a gtx 680 with the adapter it came with and had no problems using higher resolutions at higher hz. I will try CRU later on when I'm home.

According to the specifications, that is limited to 1900x1200@60hz. For most cheap DVI and HDMI converters, that is really about as high as they can go.

I remember some old AMD drivers with the EDID override completely ignored, corrected after some releases.
Maybe they broke it again, which driver are you currently using?
Anyway that limit with the custom resolutions is strange.
 
wow it's been a while since i last posted in this thread. so i've move from california to sorta the middle of nowhere in urbana illinois. unfortunately i (barely) did not have enough room to bring along my cpd-g520p, which is now sitting in my parents' garage. now i sort of regret fitting my bike inside my car i probably could have made space.

just for shits and giggles i thought i'd search for crt monitors near here. and... i found this within driving distance: https://www.ebay.com/itm/IBM-P260-C...itron-Tube-Mfg-21-1920x1440-24mm/323895672149

the price is kinda extreme? or are crts really this rare now? back in the day (well like 5-6years ago) i picked up an fw900 for like $250 or something, and a cpd-g520p for $85

:ROFLMAO:

Forget it, this is just some ebay scam, it's not even sure that screen was worth that when it was brand new. And the guy pretends to charge so much because he "refurbished it". Understand he performed a WPB (or worse, maybe statisfied himself with a dirty G2 change :LOL: ).

Just pathetic. :facepalm:

It's true there are less of them in classified ads than there was a few years ago. But that still doesn't justify such prices, the boys are old and their remaining lifetime is unpredictable without some serious maintenance.
