this is one method of displaying win 98 on an arcade monitor but it does have its faults.
It is also a useful benchmark to comparing scan converters,svideo tvs and other video methods
as picture quality is as good as it gets on a 15khz the signal is not degraded or converted in any way.and is as clear as the signal that enters your svga monitor.
Step 1.
these are the specs of the hardware i know this works with.
Ati Radeon 64ddr vivo(this should work with all radeon cards i doudt it will work with pre radeon cards as dont think they support custom resolutions)
hanterex 25 polo 15 khz,
j-pac,
software- windows 98,powerstrip,3deep,
you will also need an svga monitor
NOTE: do not try this using windows XP it will crash you pc.
Step 2.
make sure you you have a blue monitor icon displayed in you windows taskbar.
if you dont ,this is how to get it there:
Right-click an empty area of the desktop.
Click on Properties.
Click on the Settings tab.
Click on the Advanced button.
On the dialog box that appears, check the Show settings icon on task bar box.
Click Apply then OK.
A new display icon will now appear on the taskbar. Click the icon and a list of possible display settings will appear. Click on a setting to change your display options.
Step 3.
stick the pc display on your 31khz monitor
open up powerstrip.
[Custom Resolutions]
736x288=736,24,64,80,288,2,2,20,14160,6
What you want to do is this:
1. PowerStrip menu > Display profiles > Configure > Advanced timing > options >
2. Cut "736x288=736,24,64,80,288,2,2,20,14160,6" from this message to the Windows clipboard > > >
3. Paste the timing into PowerStrip by clicking the paste-from-clipboard speed button (the middle icon between Cancel and Apply)
4. If the timing is in the correct format, you'll be told the resolution has been added to the Custom list
6. Click the "Custom resolutions..." and then click the "User defined" list and you should find the new resolution listed
7. Highlite and click "Add resolution"
8.close powerstrip
step 5.
click on the blue display icon in the taskbar/toolbar 726x288 should now be added to the list.
step6
download and install stretch mame32
if you cant find this install mame32plus instead
open up stretch mame
goto Options,defaut options,display,
check the fullscreen box and set the screen area to 736x288.
set the gamma to about .75
step 7
the only windows emulators that will work are ones that you can set the resolution to 736x288
to get zinc to work just check the run in window box an paste 736x288 into the box.
change all the emulators you want to use on your arcade monitor to run at 736x288.
this are the emus i know work.
pj64,final burn,snes9x,zinc,epsxe,
Make sure you configure every thing in the emulators before switching to the 15khz monitor.
I mean every thing video,controls etc.......you dont want to be configureing anything while on the 15k
step 8
download and install 3deep software ,open up the control panel and press the set game gamma button.
this stops the desktop being too bright when viewed on a 15k
step9
click on the blue monitor icon and change the display to 736x288,
turn off your svga.
plug in the arcade monitor
turn it on and tune the h-sync and v -sync in and adjust the picture size.
you should now have a clear and stable picture of the windows desktop displaying on your arcade monitor.
step10.
run mame or zinc..................
(in the mame 32 gui click on the square in top right corner so the gui fills the screen)

The pros of using this method:
cheap.
very easy to set up.
you can use mame32
runs all games full screen
all vertical games in mame run at about the corect screen ratio(more or less)ie with black boarders
u can use Zinc and other windows emulators
dosnt degrade or convert the picture in anyway
zinc and pj64 look amazing
it rus on radeon cards so no more slow trident blade cards.
dosnt use interlacing
no colour bleeding
text is easy to read
can still use dos mame as well
stops people trying to work out wierd and wacky ways of trying to get windows displaying on an arcade monitor(i like the amiga monitor one)
cons of this method:
mame 32 uses h/w stretch
games in mame are all forced to run at 736x288 instead of there original arcade resolution
in windows all pulldown menus are cut off at the bottom due to the fact windows not supporting resolutions as low as 288.so u have to configure everthing on a svga monitor first or use a 25/15khz auto switch monitor.
cant use any front ends unless some one makes one that supports 736x288.
cant use windows xp
if you want a perfect method you will need to find a video card that has been specally made for this perpose,works on xp dosnt use hw stretch,plays all the games in mame at there correct resolutions and runs all windows programs and aplications ................................
.............if only someone could design such a card?
at the end of the day ,if u dont like it dont use it
