Soft-15KHz - slim new tool for 15KHz on normal vga cards
DirkDiggler_ESQ:
I am seeing a lot of posts that have some things in common with my issue, but not enough for me to get it fixed.
I have:
Wells Gardner K7400 (15 kHz)
Radeon HD3450 (Catalyst 11.5)
Windows Vista x64
J-Pac (jumpers on 15 kHz and 31 kHz)
DVI to VGA adapter is plugged into the DVI port. PC boots and I see the BIOS screen split. Windows loads and the screen is blank. Connect a regular monitor, run soft-15khz, install the 15 kHz mode, re-connect arcade monitor, and I now see the desktop, but it is split and the top section is slightly skewed. No changes of the horizontal position controls will get the two images to become one.
In Windows, the lowest resolution that is shown (in either that Catalyst Control Center or the built in "Change Display Settings" in Windows) is 640 x 480 and nothing lower. What am I doing wrong? I thought that once I installed the 15 kHz modes via soft-15khz, that I should then see resolutions lower than 640 x 480 in the display settings?
Would installing Windows XP make any difference?
SailorSat:
First, use QuickRes to select lower resolutions.
Second. On the blank screen issue. Try the OTHER Port :)
Split Screen = 31kHz active.
You don't have to install it every time.
If it doesn't stick -- it should read "installed 15kHz" in the status -- try running s15khz as administrator.

i've found my way to this thread because i have been trying to get my laptop which has a geforce 8200 card to work with a jpac.
is it correct that what i need is a dongle to get my arcade monitor to accept a 640x480 signal?
at the moment it looks like this with quickres and soft15khz (on the jpac, 15 & 31 are jumpered)
if i go down to 320x240, it is okay, but then lots of games i can't play at such low resolution
can you offer any advice? many thanks.

Well, you should have other resolutions available (check with quickres!).
you may have to to set the ports in nvidia control panel. vga out should be port #1.
As you can acutally see ONE screen currently, I don't think you need a dongle.

many thanks for your advice, i will check when i get home.
yes, there are many, many resolutions available on quickres, higher than 640x480 and lower than 640x480, but i have only found 320x240 to offer a stable and clear image on my arcade monitor, most of the other ones are just totally out of sync. - what i am doing is that i am cloning my laptop screen to the arcade monitor, not sure if there are any issues with that.
anyway, i will check the nvidia control panel and look for vga out and port 1 and report back.
vib_ribbon:
as this stands to be the best possible opportunity for me to get to the bottom of this problem, lemme give you, sailorsat, as much information as i can.
so i am on a laptop, with a nvidia geforce 8200 card built in with soft15khz is installed.
quickres offers a long list of possible resolutions, i pick 640x480
it is possible to select 240x240 and the laptop screen won't have any problems with it.
so with the jpac connected (jumpers on 15 & 31), i select clone (laptop screen as primary, arcade analogue screen as secondary)
as i have showed in the previous post, this is what i'll get:
if i make the arcade analogue screen as primary and laptop screen secondary, it is worse:
why it makes a difference, i dunno, but this is what it looks like:
the only success i've had, is select 320x240 res and then clone to the analogue screen (as secondary):
but that is no good to me, because i need 640x480 to play certain games.
can you see anything within nvidia control panel which i could try?

not sure what is meant by "vga out should be port #1." does it simply mean make sure the arcade monitor is set as primary display?
i have also tried only having 15khz jumpered on the jpac and not 31khz, but that is also worse.
many thanks for being so patient, and your input is much appreciated.
