New DVDO iScan Duo [2.0 firmware released] - Page 119

Thanks for your help.

Hi all
Im just about to order chromapure the auto calibrate package but before I order my equipment is in the next room will a null rs232 extension cable work at 5m length-10m length?

Thank you

I use a Serial to USB adapter, then I can use USB extension cables with a powered USB hub. I mainly use this in projector calibrations where the equipment is in a separate room.

Thank you. Will go down that track

Just ordered, Im looking forward to it.

I'm using a 10m serial cable and that is after a USB -> RS232 adapter (FTDI chip). No issues.

Thanks

Frank, DVDO run A standard rs232 cable (Supplied ) its the lumagen Radiance series that use A null cable..
The FTDI chipset based USB to RS232 addaptor's are the best to use & What both DVDO & Lumagen recommend..

I use A 5Mt USB-2.0 extension cable between the USB to RS232 addaptor and the supplied RS232 cable with no issues. Any longer & its prob best to use A USB 2.0 Active extension Repeater type to avoid possible unwanted issues..

Hope this helps..
Cheers..

Thanks Jase.

hopefully receive my Chromapure bundle next week. Just want to say a big thanks to Tom for his great service by responding to questions quickly.

Is the Duo still worth buying for auto cal or is it an old product now ? I thought the mini 3D was around $1400 but I see $2K now

The Lumagens allow 125 Point 3D LUTs and 21 Point Greyscale, but there's a limitation on Inputs on the Mini unless you upscale a few hundred dollars. Have 3 Duos on the wife's sets to make them easier to calibrate, but my set has the XE-3D to both give me enough Inputs, plus the 125 / 21 Point.

From only a calibration point it really depends on the display. With some displays there will be no noticeable benefit with the superior calibration capabilities of the Radiance. Unfortunately this is hard to determine beforehand. Also the single input of the Mini 3D should be a non-issue for anyone using a modern, multiple HDMI input AVR.

With the current prices of the Duo it is tough to beat. With my display it is very hard to see any differences. I would not invest more than a grand these days on a VP. Well maybe if it did 4K better than my display. Still for me if I am going to spend more than a grand I may as well get the REDRAY 4K player (when it comes out).

I am thinking about getting the CP auto-cal and D3 Pro to calibrate my Kuro KRP500M and Sharp Z30000 projector. Is the Duo good enough ? I may or may not benefit from Mini3D's 125/ 21 point. Is that correct ?

Try out samples each of Calman and CP, and see which meets your requirements the best.

Hi all
Just curious is still recommended to do calibrations every 100 hours ? Is that what most are doing on here ?

Thanks

I've never heard of calibrating every 100 hrs, and from personal experience I'd find it to be way too excessive. If you have the requisite gear, twice a year should be just fine. If you have OCD or are a perfectionist, at most once every QTR. When I did that my readings were within the repeatibility margins of the meter, and even where there was deviation, it still resided well within dE error threshold, so it was kinda pointless. I know with the auto-calibration packages it's now incredibly fast and easy, but even then that kind of frequency should be unnecessary unless your display is very unstable.

Thank you for your reply. In terms of hours in the globe when will it best to do a calibration?

I'm planning to have a 135 cinemascope 2.35:1 screen with the Epson 5010 projector. My question is, can the duo Iscan fill the 2.35:1 with a 16:9 format? I will be watching blue rays movie and must of the format are cinemascope, but somedays I'm sure I will be watching TV Shows and those are 16:9. I want to see those shows to fill the entire 2.35:1 screen. I see contrary information about this. Some people say yes and some people say no. Can somebody that have a 2.35:1 setup without a lens confirm if I be able to do this? Those the Duo do the zoom or the projector?

I think you can use the "Stretch" mode to customize the image to fit (but it may distort the image), or use "Zoom" to fill the screen and preserve the picture's aspect ratio, but the picture will then be cropped. The stretched and zoomed settings can then be saved as a user preset.

I seem to do it every time there's a new CP or Calman that comes out, and the last little while, quite a few Betas to check!

I think 100 hours is excessive. But then it might not be so excessive if you are dealing with a projector whos lame is set on high, when compared to an LED Flat panel.

It depends on how linear your display is. With the DUO you are setting only 6 colors each at a single intensity and saturation. For your displays thay maybe great, for other displays you are dancing around with a rubber chicken. Features like the Advanced Color Management feature in ChromaPure and I think Saturation Sweeps in Calman can give you a better idea of what is required. To get the best most accurate color out of a display the EE Colorbox is probably the way to go. They can do 17x3 cubes.. that is over 4 thousand individual colors corrected with interpolation color can be virtually perfect on an even wacky display.

Ive noticed Calman 5 does auto calibrate as well. Are they both very similar in there job or does one preform better than the other? Ive downloaded the calman 5 trial version, have to admit the layout looks very impressive.

CP is currently stating it's going to withdraw the 21 Point AutoCal in favour of only 10/11 Point. After putting a request in on the Calman Forum, the following replies are given back:

Note: This will not apply to the Duo since only the Radiance and/or Colorbox support the higher Point Calibrations.

Thank you for that. Is the Autocal on the calman just as easy to use as its on the CP?

Definitely.

Thank you.

For members on this thread what is the most preferred calibration software for the DVDO DUO?
