But with these you cannot blend !?


Yes they will.

http://www.tvone.com/edgeblending.shtml

What you'll need with these tho is a CMS device. Cheapest is the Duo. But then you'll need two HDMI to RGBHV converters to
get to the TV-Ones. You'll need a CMS with any Edge blender anyhow. So the cost for those will be there no matter what.

So this would be my chain. Blu ray, to Moome Mux splits to two duo's or radiance's, then those to an RGBHV converter to the Barcos. Unless the Duo has RGBHV out. I wish the radiance had RGBHV outs.

Or you could eliminate the Moome Mux and get two Moome Externals HDMI to RGBHV but then you'll still need
a HDMI splitter to replace the Mux. I like the Mux because of its flexibility. there are many ways you can get to where you want to go.

but they are analog - for me that was what i wanted as my switcher is analog extron with dual RGBHS outputs.

if you want digital blending then these are not for you. if you have a pair of analog signals these should work well for you.

my chain was going to be

HDMI
|
HDFury
|
extron 304 - RTC2200 - TVone - NEC XG
|
RTC2200
|
TVone
|
NEC XG

and there you go.

yep, Nash that would also work - and I thought about it (even got a 2nd HDFury) but it meant losing my other analog video inputs

HDMI
|
splitter - HDFury - RTC2200 - TVone - NEC XG
|
HDFury
|
RTC2200
|
TVone
|
NEC XG

Thats not for me Eric. Those 1250's are analog only so you need to do a D/A conversion to get to the TV-one 1250 and then leave it analog to the PJ .

Mine is digital all the way till it gets to the Moome card.

Right. I have used the analog outs from My C2-2250's and saw no difference.

IIRC Craig mentioned to many D/A and A/D conversions in the signal chain can cause an issue and reduce image quality. I haven't tested it, so I defer to his experience in this area. Hopefully he can weigh in on this.

I am not sure that is right. While I am not blending but I can tell you that image quality in terms of sharpness at least is better the closer to the projector you can get a digital signal before converting to analog.

I have never liked that calculator. It uses Extron's formula, which takes the whole chain in account. CRT pjs are at the end of the chain.

@Nashou: Did you use the EdgeBlend Software Tool inside the TV one's when you are connected with the COM port ? Or did you set everything on the units itself without connecting to the serial port ?

I do some testings now on my CRT monitors.

Your input into the TV one's is: 1920 x 1080 ? and output 1064 x 800 ?


thanks
ElTopo

No I did not use the edge blend software tool. When I did my blend it wasn't available yet. So i already had the blend set up
manually with no tool used.

Yes to the resolution. I used 1080p@24 into my lumagen and output the same res to my TV-Ones, then from the Tv-One I used 1056 x800. I also have 1064x800. I forgot why I did it that way, there was a reason but can not remember. I use the 1056 . The size will depend on the size of your blend Zone and Zoom amount. So I think the one with 1064 has the smaller blend zone and larger Zoom %.
