So it's like the ANX9847, some chip are better than others, max pixel clock of my eight samples:
Another thing is that 62967 doesn't work with all the video cards and when this happen the DP cable must be replaced.
It would be interesting to know if the same...
The first prototype of 62967 was better, both the connector and the adapter housing, 340 MHz is also the speed of it.
About the ANX9847 test you can try to swap the chip from the 62967 to the HBFBB.
I think that the electrical diagram of the ANX9833 is like that of the 9847-6211-6212 but there...
Extending the DP cable may cause performance degradation with that adapter like no stable HBR2 mode, so be warned.
About 10 bit adapters read here
Also chipset like LT8711X-B or LT8712X of the Vention adapters may have 10 bit DAC.
No one did 10 bit test with these adapters.
A very nice job...
Try to contact the seller (Vention Technology) and ask why the CGMHA is unavaible.
Also ask if they can sell the CMFHB which is the new HDMI 2.0+VGA model with the new Lontium chipset.
Eventually try to search for CGMHA or LT8711X-B, you will probably find adapters with a different name...
The limit factor is always the digital receiver of these chipset.
If the CGKHA really has the IT6562 chipset it can't go over 360 MHz, the digital receiver can't do more than that.
If it goes over 360 MHz it means that the chipset is one of the Lontium and the Ventium specs are wrong.
Can be that Amazon web page description is for the old model,but they actually sell the new model (CMFHB) which is aesthetically the same.
Or maybe they have both models and you don't know what is shipped.
You can use some hot glue to block everything and adhesive copper foil to shield, or use the shielding cover (if it fits) and the molded part around the cable end of the original connector.
He has probably read about it here, but the model shown in the video can't do more than 360 MHz.
Yes 32AWG, aesthetically identical to the others and the connector is different from all the others, 8 samples and 4 different connectors.
Maybe that day the guy who assembled the adapter used a good cable or the connector made the difference.
About those samples:
Cables aren't much different exept for the last sample with AWG30, they are not bad like those usually used on most adapters but obviously not good enough for the ANX9847 chipset with most video cards.
Connectors are at least mechanically much better with a proper lock...
AMD 5850 does not support HBR2 so even if the adapter was perfect it couldn't go over 180 MHz.
With 380X is another story and if it isn't stable with HBR2 the only solution is replace the cable or at least the connector.
About AMD cards and 62967 i tested 8 different samples, some with cable and...
This happens when the monitor is seen as non plug and play, when for some reason the monitor EDID is not seen by the graphic card.
Try with CRU monitor utility and set a custom EDID or copy-paste a full EDID backup of your monitor if you have it, it also works with non plug and play monitor...
Oh i forgot that the USB-C voltage is 5 V to 20 V and displayport is 3.3 V, the chipset should have a dedicated pin for that if it is designed to be connected directly to the displayport cable as well as to the USB-C cable.
Unlike other chipset here the USB-PD controller is inside the chip, with the four DP lanes and power is easy because they go into the same pins.
The problem is with the AUX channel and the hotplug lane, AUX should go to the two SBU1 SBU2 and hotplug to CC pin but i don't know if the signal is...
Ok, so now we know that they have connected all the four lanes to the chip, i was worried about that.
About the 10 bit, just ask if there is an option in the graphic panel to set 8 or 10 bit on the digital output, because without that I have doubts that it can work.
There is a miniDP to VGA...
Interesting, can you ask them to try with higher resolutions like 2304x1440 80 Hz, image quality or if they can set 10 bit on the digital output?
DAC speed is by specs 200 MHz, like the Synaptics chipset of the DPU3000, but a Lontium engineer told me that it can do much more than that.
It is important to check the specific model code of any card because with their names it's a mess.
Example with Gigabyte RTX 2070 Super:
GV-N207SAORUS-8GC with USB-C
GV-N207SGAMINGOC WHITE-8GD no
GV-N207SGAMINGOC WHITE-8GC yes
GV-N207SGAMING OC-8GD no
GV-N207SGAMING OC-8GC yes
I don't know why they don't list the USB-C output but actually all Nvidia RTX reference cards (Super or not) have it, the controller is inside the GPU.
From what i have seen most of the custom RTX 2070-2080 have the USB-C connector while most of the custom RTX 2060 do not.
Anyway with cards like...
If you can set that resolution on desktop you are fine, after that load the game and make sure that the resolution in not changed (with game previously set to 800x600)
If the game limits the FPS to 85 look here for some tips:
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.
Anything you put in CRU is ignored over that pixel clock?
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...
It's nice to see that 62967 works with your new card and good to know that those registry keys for dithering are working, now let's see how long Nvidia takes to implement it officially.
About the USB-C adapter it should works without problems with RTX cards, at boot time and without any need of...
I found an adapter that can potentially have the same performance of DPU3000.
The chipset is the Lontium LT8711X-B which has the same specs as the Synaptics VMM2322.
I asked Lontium about the DAC precision and seems to be 10 bit,but it's a thing that must be tested.
The adapter is the Vention...
That Logilink CV0109 is a dual chip design PS8339+ANX9833
Parade PS8339 is for DVI and HDMI
Analogix ANX9833 is for VGA and its digital input bandwidth is limited to 180 MHz
So with this adapter you can do max 180 MHz on analog output
Delock 87685 and Sunix DPU3000 are one chip design with...
Sunix DPU3000 Power Consumption 1.45W (don't know if max or typical)
Displayport 3.3V 500mA (1.65W Max)
Classic USB 2.0 power 5V 500mA (2.5W)
USB 3.0 power 5V 900mA (4.5W)
The adapter works with only the displayport cable (the included one) so the chip is probably powered by the 3.3V line,not...
Well the DAC integrated on old graphic cards is inside the GPU so it seems impossible to cannibalize it.
Also with the integrated DAC you don't have to take care about the digital output for the same reason.
But with an external adapters with a proper 10 bpp DAC we must take care of it because...
By digital input i mean the input of the adapter which is the digital output of the graphic card
By digital output i mean what exit from the graphic card and what you set on graphic options
Digital receivers of these adapters usually pass the signal as it is,if the DAC is 8 bit the receiver...
That is only a DAC, it needs a digital receiver and everything else and i don't know custom adapters with that chip.
Adapters with 10 bit DAC:
Not 100% sure but these seem to be the correct specs:
HDFURY Nano GX 10 bit DAC but digital input is 8 bit
HDFURY2 11 bit DAC but digital input is 8 bit...
I don't want to break balls but are you sure you want to buy the DPU3000?
Because if you use resolutions like 1920x1200 90Hz or 2048x1536 55Hz there are much more economical solutions.
Anyway if the card you will buy (already bought?) doesn't have USB-C output or you want experiment with very...
That is the max possible digital input bandwidth because the displayport receiver is a four lanes HBR2,so 720 MHz 24 bit or 576 MHz 30 bit.
The max analog output is another story,i said tested up to 500 MHz thanks to your report,if i remember correctly someone else in the past has tested...
Don't worry,most of the adapters are officially 1920x1080 60Hz, that's why we search for chipset specs and we test them to see how much they can do.
The most important thing is the digital input bandwidth, DAC can do much more than official specs.
Sunix DPU3000: max input 720 MHz 24 bit (tested...
About Plugable USBC-VGA, it works without known problems up to 1920x1200 96 Hz, but has been tested with laptops and special USB-C cards like Sunix UPD2018.
Nvidia RTX cards are the first with the USB-C output, it should works without problems but it's a new thing so who knows.
If your RTX card has a USB-C output and you don't need more than 1920x1200 96 Hz you can buy on the USA market these adapters:
Plugable USBC-VGA https://www.amazon.com/Plugable-Compatible-Thunderbolt-resultions-1920x1200/dp/B015X0CV1C
tested by other users with a pixel clock of 330-335 MHz...
Very strange with native DAC, do you have other monitor connected to the graphic card?
I had the same problem in the past but only with a secondary Samsung monitor connected with an adapter and never with the FW900, i thought it was an AMD driver bug.
Initially i used your same solution with...
DMT isn't a timing formula, but it is a VESA document containing a list of resolutions and refresh rate with different timings.
Timings can be GTF or CVT or CVT-Reduced or custom (very old resolutions)
If you set a resolution in Windows who is on that list, it uses those timings.
So with some...
