My modded moome Marquee v3 does 207mhz pixel clock with no problems above that the moome breaks up on red channel and neck cards blow at 1080p 72hz
Its kind of hard to recommend something not knowing what its for, so it would be a great help if you list your videochain from source to display, every step, and even better with pictures.
Analog displays is not perfect, and some will look better with a dac that is not to high bandwidth, most analog displays are not made for high bandwidth use, not that some of them cant display, but thats far from the same as resolving, or working well with it.
Also you mention the moome, there is like 20 moome products, so if you tell what specifik moome product you have, ill be able to see if i have it to.
As i mentioned in the last post, most/ all the converters i have will support any resolution inside the bandwidth they can handle, so if you have a moome that dont, ill guess its defect, or you have something else in your videochain that dont like the specifik resolution.
I think you might have a defect, or picky moome, if they work right they will work with anything balow 165Mhz you can trow at it, and its not uncommon to see defect moome cards.I have a number of CRT projectors at my disposal and I don't want to be limited in the d/a conversion before the projector that I happen to use as otherwise I would have to get the internal cards for Barco, Sony, NEC and Ehomes. So I would want an external box with the least rolloff at 200 MHz, if it goes up to 300 MHz even better as there are claims for Modded barcos and Marquees that supposedly go that high.
Sorry about the Moome Box, I left out that I have the V2 version that syncs very well to for example 1080p 72 but not to custom resolutions that I often like to use so it is only of limited use. Just for fun I tried for example a resolution of 2400 by 1000 with the Moome V2 external box and a Moome IFB Full HD - no problem with the IFB but no joy with the external box, both signals were under 165 MHz bandwidth by the way and the IFB card even syncs happily to signals that have a bit more than 200 MHz bandwidth.
It is rather hard to do pics of the smpte pattern, I can remember that from a long time ago when I made them with my 10 PG when I still had a decent camera - now I only have a smartphone that is hard to hold still and focus in a low light situation.
I will never come from the player directly, too many limitations and I need multiples of 24 so it has to be a video processor. Regarding the Moome card as I mentioned I may also want to try and use a 1209s, Marquee or Barco so I would definitely prefer a high bandwidth external solution - if I only feed the G90 1080p 48 most of the time or even less than it won't be an issue anyway.
Can you elaborate on the reduced bit depth and chroma issues of the Radiance?
Surely they will show up in test patterns?
I need it in any case for setting the gamma curve the way I prefer and also for custom resolutions and a few other things that are important to me but I would like to know about these limitations you mention.
The other day i was testing 1080P 60hz 422 12 bit out of my Panasonic UB900 UHD player, and tested true the Hdfury4, wich is listed as deap color capable.. It do accept it, and output it, but somewhere in between something is not so lucky.
The moome card deals with whatever 1080P i trow at it without messing it up.

Hi Stridsvognen
Any updates on converters since last year?
I have Sony GDM-FW900, it's a 24" CRT monitor. I need converter that would transparently resolve 1920x1080p at 120Hz, that would strip HDCP and could display 24FPS with triple flash or more (96Hz, 120Hz).
I would like to run 5 year old PC games at super sampled 3840x2160 Nvidia DSR at 120FPS from latest flagship Nvidia GPU.
Besides PC I would like to connect it to Apple TV 4K and Oppo UDP-205.
Could you recommend me some options?
Thats way above the bandwidth of any of the converters i been dealing with.. Above 200Mhz pixel clock is a tough one to crack, and i very much doubt your monitor will resolve a 300Mhz pixelclock, as your surgesting 1080P 120hz.
There might be some graphic cards with VGA out that can do 300Mhz
What would be interesting is to see how your monitor deals with the SMPTE pattern as you run it now.
As you see all the converters i tested here strugels to do 1080P 60hz, and the best ones will do 1080P 72hz.
4) You were criticizing HDFury for weak price to performance ratio. Do you think used 3DFury or HDFury X4 at $165 with shipping are worth it? There is no hassle of modifying $20 Chinese converter.
looking at the specs of your monitor, and i think you would be best off trying to get 1920x1080 72hz running, but as your porch timings are high, it ends at 216Mhz, and thats not any standard timing, so ull need a processor or HTPC of some sort to make that happen, ill think as i mentioned earlier that a video card with VGA out that can do 300Mhz will be your best option, the other is a Lumagen Radiance Pro, and then custum timings to do your 1080P 72 timings, and see if you can make a moome converter deal with the 216Mhz, its a close race, ill say its a fairly slim chance of getting that to work well.
4K is way off limit as you would push 600Mhz, and as you cant deal with WCG and HDR, there is no need to bother dealing with 4K content at all.
