Sorta. It would take a hell of a new VP to upscale to 4K as good or Better than the Sony 1000ES. So far all the blu ray players and receivers haven't come close in sharpness. The best so far has been the latest Samsung 7500. Either way VPs are still fading fast. 4K is their last gasp.

My Duo is freeze and can't do nothing. Can't detect input and no out put. Can't use button or remote.
Tried to unplug power cable and plug it again but it didn't help.

So sad that my unit was ran out of warranty last month.

I contacted Iscan duo for RMA (maybe if they can repair) but still no response from them.

Now I'm looking for used duo or maybe upgrade to lumagen 2021.

Does anyone know how to reset duo ?

I've recently acquired the Marantz AV8801 and I'm curious to find out if anyone is running there blu ray player through the Duo and just audio out to the marantz? The reason why I'm asking using that type of configuration I just mentioned Marantz recognises the audio as PCM 2.0 stereo coming from the Duo. I removed the Duo out of the chain and plugged the blu ray players into the Marantz and everything was fine.

@Franin,
Are you sending the audio to the receiver using audio HDMI output? Have you tried the optical or coaxial digital audio outputs from the Duo?

I'm sending audio to reciever using audio hdmi. I don't want to use optical or coaxial because I prefer Dolby true hd and dts HD MA. It worked fine with my previous pre amp but now it seems there is a compatible issue with the Marantz.

Why no new VP's from DVDO? I wonder if this unit can be upgraded to do 3D LUT calibrations.

There hasn't been any development of the ABT processor since the ABT2015. I doubt that there will be any further develpment of it. Time waits for no one, with 4k around the corner. I personally would like to see them investigate the new Qualcomm Snapdragon 800 with the coresponding Krait 330 GPU SOC. Qualcomm is the owner of Hollywood Quality Video now. I bet DVDO could come up with a terrific scaler/ switcher/ re-sizer/ noise-reducer/ artifact-reducer based on this CPU/GPU combination. If I knew how to do it myself, I would. It seems to me that we are entering a new golden age of less expensive, but more powerful silicon than ever before.

The DUO should be sending out the lossless audio out to you Marantz. I suspect its an audio ouput setting and/or an input setting on the DUO for you bWhat happens if you send the audio out from the either of the 2 video ports? Checked to see if any of the setting changed when you changed out the receiver. Or you may need to check for update for the Marantz.

I just noticed that my DUO firmware is build 0.79. Is there any compelling reason to update to 2.0 or stick with what I have?

Going to 2.0 will get you a color management system, as well as new features and fixes for various bugs. The latest firmware is v2.41, I just discovered. You can check the website for details if you like.

Ah, okay. The CMS is one reason I bought it in the first place so that is pretty important. I don't have the equipment to utilize it at the moment and will most likely have a local ISF person do that for me. The only issue I have experience with the DUO in my limited use thus far is that sometimes when I press the aspect ratio preset button to toggle between those, the label in the upper right hand corner will stay there until I start a movie or do something to change the image on screen.

When using the Duo as my pattern generator during calibration, how do I set it up so it does not affect the results? I found where to put CMS in "passthrough" mode on my duo. How would this be done with grayscale? Move all settings to zero? Any other settings that should be changed?

Or, should I just leave everything alone?

Thank you,

Steve

If you simply want to use the Duo as a pattern source, then turning the CMS bypass "on" will prevent the Duo's CMS settings (including grayscale) from affecting the patterns.

Am I alone here?

I have had to carry out a factory reset once again as my Duo will not pass all the Audio to my TV, I get some Audio but no dialogue. A factory reset fixes this.

To be fare it has been about 6 month's since the last time, all the same it's a tad annoying.

I'm running version 2.32

I've never had this issue. Try the latest firmware. If that doesn't work for you, or causes other issues, you can always go back to an earlier firmware version.

Cheers.

I tried the latest firmware a while back, it gave me nothing but trouble so I reverted back...... No worries, I will just keep an eye on things smile.gif

Hi there,

I was wondering if anyone has tried using Chromapure to connect to the DVDO Duo using a USB-RS232 adapter. I am using a MacBook Pro Retina running a Windows 7 (64bit) using Parallels 8 software. I can't seem to get Chromapure (or possibly the Virtual PC) to connect to the DVDO Duo. I kept getting this message:

"Unhandled exception has occured in your application if you click Continue, the application will ignore the error and attempt to continue. If you click Quit, the application will close immediately.

Access to the port 'COM 4' is denied.
"

I have tried to change the port from COM4 to a higher number such as a COM11, and I kept getting the same error messages. As a result, I am unable to run the Auto-Calibrate module for Chromapure at all.

Has anyone calibrated your DVDO Duo using Chromapure Auto-Calibrate module using a MacBook Pro (OSX-Mountain Lion) virtual PC environment? If so, would you be able to help walk me through this process? At this moment, I have just paid for a rather expensive software without being able to get it to work.

Here is a screen capture of the error:

Thanks so much in advance for any response. Thank you!

I don't think the issue is the Chromapure but the settings on the Virtual PC (Parallels) or Windows 7 (OS of the VPc). Oh btw, here is the error report:

Not that it will help you, but I've used ChromaPure with my DVDO iScan Duo connected with a USB-RS232 adapter, and it has worked flawlessly with Windows Vista, Windows 7, and now Windows 8. Absolutely no problems whatsoever. I don't use Apple products.

It is possible that the adapter you're using is the problem. You might consider trying a different USB-RS232 cable , or check the drivers for your current one. You also need to make sure that you have the same configuration for your adapter com port as the configuration for it in ChromaPure (usually Data bits=8, Parity=none, Stop bits=1, Flow control=none, and make sure the baud rate is the same as you have set for the Duo and in ChromaPure (19200 works for me))

I have bought a new USB-RS232 adapter but haven't try it yet. I hve made sure the configuration is the same in both the PC and the Duo so it might be the usb-rs232 adapter, or the handshaking of the virtual pc or the rs232 cable itself. In any case, thanks!

You have to ensure that the baud rate is the same in three places: CP, the PC, and the Duo. 19200 is the default.

If it still doesn't work, then close CP, delete the configuration file, and then try again. You'll have to setup the signal generator from scratch.

Hi Tom,

 

yes I have done all that. I left the Duo at default and then configure the Chromapure and the PC, but no dice. Initially I thought it was the serial cable bed I used a Null variety instead of a "Straight-through" Replacing the cable didn't help. So I have bought a new USB-RS232 adapter and hope that this will work. Have not try this yet.

 

I suspect iot may have nothing to do with CP, or Windows 7 but the Virtual PC environment in Mac OSX Mountain Lion. There must be something I didn't do right in the settings of the hardware emulator of Parallels 8.

 

In any case, will try this weekend to see if the new usb-rs232 adapter work.

Coming up - Seiki 50" 4K and the iScan Duo - should be interesting! (or Not!)

Did you delete the config file?

Hi Tom,

 

Haven't started on this yet because School Term is in session and has been rather busy. Will try to work on this in the weekend and then update. Thanks v much for your help.
