act labs light guns and k7400

[newmanfamilyvlogs]

I've got two act labs usb light guns that worked great on a pc monitor, but I've been unable to get the calibrate screen to come up on my K7400, Soft15kHz, and separate v and h sync setup.

I've tried several non-interlaced resolutions and all I get is a single white line at the top.

Anyone have any insight on anything else to try?

Decided to re-visit this issue since I'm really itching to play some gun games on my large monitor..

I pulled out a beleaguered K7000 I have (really needs a capkit, and the plastic retainer on the yoke has disintegrated) and hooked it up to a PC off the 'pile'. The PC has on-board ATI graphics (Radeon IGP 320 according to display properties) running drivers 6.14 10.

I hooked up one of my guns, flipped it to calibrate, and got a proper white screen, just as I should.

In fact, even though the convergence is off by almost a quarter of an inch on all colors, the image is flag waving like a hurricane, and the top and bottom is rolled, it was still surprisingly accurate.

I guess it's time play musical video cards/drivers and see what happens.

Well perhaps it's a monitor issue then.

I just hooked my existing configured cab PC to this K7000 and it worked and calibrated correctly.

Now I'm really confused. What could be different about the K7400 that the calibration screen would not display?

can you post a photo of the non-working monitor on a standard game test screen (something that fills the screen crosshatch etc.) and then one with the calibration screen in it's line format.

perhaps if we had some photos of the actual monitor with the issue, we can better give out opinion of what the issue may be.

Will do. I'm away from the the machine at the moment to take a picture with the gun attached and in calibrate mode, however here are some pictures of a crosshatch. I was attempting to do a single large panorama. None the less this should show you what you want to see:

I also swapped out the video cable for the one I used on the K7000, in case using the second set of h/v sync pins rather than the first made a difference; it didn't.

does the 7400 display a regular white screen (not the calibration screen) properly? if not, i would suspect a B+ issue

if it does, i'm wondering if the calibration screen has a weird sync signal or refresh rate.... you could check by displaying it on a pc monitor. most monitors will tell you the frequency and resolution of the signal somewhere in the menu....



i'd compare a regular game screen (where the 7400 displays properly) and the calibration screen (where the 7400 lines on you) and see if they are different.

Ill try an all white screen but that seems strange since I've not had any other issues like this so far.

As for the other suggestion, im not sure I have a monitor that displays that information to guest it with. That calibration screen is supposed to be identical to what's going in since you recalibrate at every resolution. Moreover on a multisync crt it doesn't change modes when you go into calibrate.

Is this thread of any assistance?   Link from Act Labs

I've looked over that several times. That's where I initially saw about not using Composite sync. Like I showed in earlier pictures, it WORKS on a K7000 just like the guy in that thread is using, using the same cable between the two monitors.

I saw a thread from back in 2003 where a guy claims he had his guns working on a K7400:

Of course that's the only post that person ever made.

When I pull the trigger, the screen flashes what appears to be green, which is even more odd since the colors are correct any other time.

lilshawn:
I filled the screen with all white, and the display was unaffected.
