I also tried the predefined resolutions. 720p@120 works fine for example.

Firstly, I lead you guys a little wrong with the timings... I haven't thought in terms of interlaced in a while. My spreadsheet for clock calculation will not quite get you the correct clock with interlaced resolutions. What you need to do instead is just copy my timings from the photos above, or use this formula for interlaced.

Fc = [Vt * Ht * (72/1.001)] / 2

Where
Fc = the clock rate
Vt = Vertical total pixels
Ht = Horizontal total pixels

With standard 1080i timings just change the clock to 89010989 Hz to get an output of 1080i 71.93 Hz.

I tested 1080i 96 Hz but it did not work. The Radiance reported 96 Hz, but the projector did not.

Thanks a lot Craig for all your explanations and screen captures., but I give up because it still doesn't work even by putting the exact same values as yours.
I will keep my HDQ (unfortunately) to get the 1080i@96.
There will still be a mystery to me that the HDQ can give me 1080i@96 when my XD Radiance cannot.
Tomorrow I will do a last test with my Pionner TV instead of the BG808.

If I select that mode or any other non-60Hz mode, then switch to the new 1080i 72Hz mode I get what looks like 1080i 60Hz (not sure how to tell for sure) along with a bizarre status indication like Fh=31.7k, Fv=56 (it varies) on the Barco. If I switch to the 1080i 72Hz mode from a 60Hz mode I get what looks like 1080i 60Hz along with the usual indication (Fh=33.8k, Fv=60). It seems to be trying to keep the refresh rate of the previous mode.

I saw the same behavior before the firmware update.

Yes, I am past that now. I was talking about other custom modes I have already been using including 1080p48, 900p72 and 817p72 which all work as expected. Then I am switching from one of those, or even a standard HDTV mode, to the already CORRECTLY programmed 1080i 72Hz. I am not going back in the Custom Modes Timing menu. My only point was that the outcome on the Barco seems to vary depending on which of the other custom modes I transition from. In any case the status either changes to nonsense values or stays at 60Hz.

The indication on the Radiance however, is the same as yours "1080i 71.93Hz" regardless how I get there.

We had this discussion before about hardware vs. Software limits in the non+ Radiance models. I don't remember exactly the outcome but there was some doubt I thought. I wouldn't be surprised if the software is limiting output in some way based on a combination of factors, which increases possibility for a bug.

Craig,

I can display 72, 96 even 120Hz correctly with my XD on my BG808 but only with progressive signal (720p in my case). The problem is on interlaced mode.
Anyway, I tried on my PC monitor and I have the same result as on the Barco ie 33.7KHz 60Hz (1080i@60) whatever interlaced signal I put on the Lumagen (1080i@72 or 1080i@96).
It seems that there is something wrong with my XD.
I don't know if it is related, but after I installed the last firmware some of Custom Mode labels have strange values. For example, instead of having Custom Mode0, I have BAR80i or BAR80p for Custom Mode7. If I do a factory reset, I have sync problems (with any input signal) on the BG808.
I'll email Patrick with my results.

That's weird about the labels!

What are you using for a video DAC, HDFury?

Test repeated with 040513 - still no go.

Email sent to Jim and support@lumagen.

I talked to Patrick again and he may add 1080i 72Hz to the default output modes so that you guys can just select it instead of creating it. He says he will also look at 1080i 96Hz and if it's any easy fix he will make it.

Craig, believe me or not, I never changed the custom mode names. I don't even know it was possible Wink

. All I did on my XD is calibration (auto-cal and manual) and chage of resolution.
I'll try your service level reset and I'll send you my config. file

Please you two, send me your config files!!!
