High-Res Monitoring Solution: Low Cost Semi-DIY project

Did you press the button down on the Mayflash?

Also, Zak said he had issues with the HV20 as well. I'll have pics up of m'self actually using this setup soon. Gotta wait for them to show up in me email.

I wonder if the HV20 just doesn't work with this at all.

Off course ;)

But I've tested the HV20 with Mayflash on 5 other displays (3 CRT's, 1 TFT + TFT/HDTV) and none of them worked. All out of range...
To be precise HF 28.1kHz / VF 50.0Hz
That's something most monitors don't support... and I've looked for the display specs of the Hitachi screen inside (Hitachi TX20D16VM2BAA), it says the following:

HF Typical 31.6 kHz / Max 39.2 kHz
VF Typical 60 Hz / Max 75 Hz

Also, I've tried to hook up my component DVD player to my HDTV using the Mayflash and the VGA-in on my HDTV, nothing, same for DVD->Mayflash->Lilliput
That's probably because it's all PAL and the Mayflash only supports 480p, 720p, 1080i, and 1080p and no 576p.

But back to the point...

"1080i/50Hz has a horizontal scan frequency of 28.1kHz, while 1080i/60Hz has a horizontal scan frequency of 33.6kHz"

Monitors usually don't support HF of below 30/31kHz
Maybe all the problems are only due to the PAL frequency?

That's one thing I haven't tried, using it on different displays at home. The only one I needed it for was the Lilliput.

What's your HV20 output set at? 1080i? That's the only mode that works with my Mayflash > Lilliput setup. 720p doesn't work via Mayflash, which is fine anyway for me.
 
Yep, 1080i, it's also possible to select 576i but the Mayflash doesn't support that mode, and the Lilliput doesn't like that one either.
But I've hooked up my Lilliput again to my computer and trying different resolution right now (with different refresh rates, expert mode)
 
Have you had any luck with your PC outputting different resolutions? I got it to work with a whole gaggle from OSX.
 
hi there. i'm back. okay... with the MAYFLASH i get identical results from the HVX200, HV20 and the component out on my Kona 3 brealout box on a final cut pro bay. there is, well, what you can see in the pics below.

this is the output from my Kona card. that's why you see a matted image. along the bottom you can see the "tear".

here i'm outputting bars to the Lilliput. makes it clearer that what the "tear" is, is actually an offset doubling of the image. not like the vDIGI transcoder though. this is much more faint.

close up of problem.

and the odd thing is, that if the Lilliput's video input toggle is set to "PC" when the unit is turned on, i get a double image. however, if I set the unit to Video 1 or Video 2, shut it off, turn it back on, then toggle the input from Video 1 or 2 to PC, I get a much more stable image. but one that still is not perfect (as seen in the photos).

i should add that i get this on both Lilliputs and with both MAYFLASH transcoders and with three different cources (HVX, HV20, Kona card).

That's crazy-weird. How can I replicate that tear on my LCD? I'd like to see if I've just been blind to it or it's not there!
 
Thanks for the info ZAK,I had ordered a mayflash and it came in last night. I hooked it up and the image looks great. I'm not getting any ghosting that I can see, but I have no color bars to work with as the HV20 can't generate any. Maybe I'm blind too :)

I guess you have an NTSC HV20? Are you running it in 1080i component out?

Still no luck with my PAL HV20 :huh: My guess is it's the 50hz (PAL) 1080i signal which uses a lower horizontal frequency than the 60hz (NTSC) version and the Lilliput just can't display it...
 
Hmmz, I checked it with my other HDTV downstairs and the combo works without a problem on that one. So there's nothing wrong with the Mayflash. I'll try to get the specs of that HDTV...
 
Good news for me
I still waiting for my s-video adapter to come by mail, but out of curiosity and a little free time, I decided to hook up my RCA component cables to the lilliput and dvx and presto, I got a beautiful signal.
From the RCA out, I have better resolution and can see better than I can on my 14” Advent TV [that I’ve been known to drag around]. That may not say much for the TV, but 14” vs 7” wow. Better than both lcd and view-finder on the dvx as well. Cant wait for my SGPro adapter now!
 
I told you, Bwest! The RCA looks very nice and is probably more-than-good enough for SD.

On the tearing with the Mayflash, I reconnected it last night and did bars to the screen from the HVX: no tearing at all. I will have my camera today to take pictures of it so you guys can see.
 
Actually... I think I have a 619GL as well. e_e; I can't remember! I'll check when I get home lol.
 
Just a quick question... u guys are also planning on making the LCD's double as prompters? if so can you do it without a laptop possibly from a smart phone? :)
 
Never thought about that! But they're a little small for that, right?

I am definitely going to get into a touchscreen setup w/Laptop, but never thought about Prompter.
