That's probably what I'll do with this thing, once I get it, and I find a used Panasonic plasma that isn't ruined by burn-in :D
Be a shame to add all that input lag though, I think a DVDO scaler would be better.

Is it much different in terms of lag? Not that I have any experience, but Fudoh's page suggests the Gefen is only slightly slower than a DVDO, and it was stated here recently there is no lag from the HDFury.

I'm interested in the best way to get analog VGA output here as well as I'd be interested in potentially using this with a 31kHz-only arcade monitor.

If you buy the version with DVI Out, you could buy a DVI-D to HDMI Adapter and then connect that to an HDFury or HDFury clone. If you buy the pre-order version, you could simply connect directly to an HDFury type device.

Quoting Fudoh's advice from This thread, a $30 chinese clone would probably do the job nicely.

That converter you linked may work nicely, but I have no clue as to the quality of the device so I cannot say for sure.

Should work fine... StarTech makes solid hardware, and I ordered the complete version with DVI-D out, so this should be one of the cheaper straightforward solutions. Still, I wonder what Marqs thinks... Marqs?

Form complete. Really looking forward to it. HDMI-VGA adapters are dirt cheap and work really well in my experience.

Hopefully this stays around for a good number of years so I can buy it when I'm no longer a college student. Good luck with the first run marqs, sounds like you'll easily hit the first 50!

Definitely don't order one of those! The reviews are entertaining though :lol: Startech adapter you linked should work great or any cheap ones of those type. I've used them before with no issues.

I clocked it at 30ms with Leo's lag tester, compared to 6ms with the DVDO, with the caveat that the DVDO gets much more lag with systems with off-spec refresh rates (though apparently the VP50, 30 etc do not).

Can we still test if 720p will work with the modeline from last year? Seems to work perfectly fine on my Sony TV.

Edit: Tested again with Linux. It doesn't work.

Will the current hardware layout be identical to the final one?

That's true, but there's noy many options. Ideally the whole system would be in a metallic case like 80s electronics, but that's way out of scope for a DIY project. A small amount of glue holds the display quite firmly in position so it shouldn't get detached easily by accident, but of course packaging must be done carefully.
Could use longer spacers and a slot for the toggle switch?
Is that an on-off switch, it's not noted on the plan view?

I was wondering today if the whole thing couldn't be designed to fit in a standard 1U mini-PC rack-mount case. You can pick these up for £20 or so, of course then you'd need to design backplates etc... so lets get the existing one out of the door first before entertaining such notions :mrgreen:

I was about to make a separate thread on asking about the XRGB units, but this thing looks far more interesting. How much better does this thing perform compared to the FrameMeister & XRGB-3 on down? I want something for PS2 & Xbox and have a low-lag LG 24gm77 gaming monitor. I was considering picking up one of the Micomsoft boxes, but I may just wait for these.

Yes, you can still use that to test whether linetripled modes would work. Interesting to hear that it's accepted by a Sony TV - which model is that? It'd be awesome if their new low-latency TVs would support modes like that.

No problem, it's just for convenience.
xadox wrote:Will the current hardware layout be identical to the final one?
Aside from DVI replacing HDMI in non-DIY version, the remaining changes will be mostly aesthetical.

The current height of the spacers matches the height of input video connectors, so top plexiglass keeps them firmly in place when swapping cables. It's the power switch as you suspected.

It's an older model, Sony KDL-40EX650.

30ms of lag, I already answered that above :) I can confirm HD Fury 2 is lag free though, at least that's what Leo's tester says.

I get what you are saying. But the DVDO Edge does craptastic 480p to 1080p scaling. Adding so much ringing destroys the purpose of this thing in the first place :p

I'm joking, I know most people doesn't mind. But I wouldn't like it :)

Craptastic is way off the mark, it's hardly cutting edge and indeed worse than what many modern TVs do, but honestly I did side by side comparison of DVDO and Gefen's scaling and most people couldn't tell the difference. Add scanlines in and the DVDO's scaling is absolutely fine.

I'd take less lag over less ringing any day anyway.

Preordered a complete one... I'm thinking of preordering the diy for having also an hdmi version... Are very high soldering skills needed?

I'm so pumped to try this!

I believe the both the DIY kits and the complete units of the first batch will have HDMI ports.

EDIT:

Seems I was misinformed. As you said, DIY kits will include HDMI ports while complete units will have DVI ports.
