15khz and regular Lcd same gpu Help

[m.andrade1]

Hello Guys
Have a Ati 5450 with VGA and DVI ports, on vga port it´s running win7 64bit CRT_Emudriver beta 8 with 15khz, GM 0.194b running perfect with an arcade monitor.
Is it possible to get a regular LCD on DVI port with it´s on desktop and everything, i mean not just to display marquee on dvi port, but use it as a regular pc with lcd display, the reason for that i want to play around with some HLSL just to check if it´s good or not.
Doing that want to keep my arcade setup untouched, with my desktop thru vga 320x240, 15khz, running beaultifully.
And want to have a secondary port with lcd running regular footage 1280x960 or 1600x1200(4:3) with it´s own desktop and plan to have 2 GM versions, one that already have (Generic_15) and another with LCD setup
Any clue how start it will be very glad !

Thanks
Marcos

Yes, it's possible. The other thread on the front page about 15kHz and 31kHz monitors applies, even though it's technically about marquees.

Hello buttersoft
Thank you so much for your help !
Will follow those steps, but do you think i can have diferent desktop with individual resolutions, on the vga port 320x240 15khz, and the dvi port 1600x1200 with regular LCD hkz?
I´m a CRT fan! but as people are talking much about HLSL stuff, decide to give a try, to see the results if worth, do you have any experience with that, i have a 4:3 Dell Ultrasharp 2007fp monitor, with very good contrast and brightess settings, i think will try some fake scanlines and effects on that !
Did you make any tests on that ?

Thanks
Marcos

Yes. The EDID for each monitor tells the driver what that monitor can handle, and the driver tells windows. The CRT has it's EDID emulated by crt_emudriver if you have a 5000 series or newer Radeon card. The LCD provides it's own EDID the same as all newer monitors do.

All my MAME/GroovyMAME efforts have been bent on 15kHz - i know nothing about HLSL or filters or CRT shaders save that none of them look quite right to me. And that's even before you take into account that a photo of a butterfly looks nothing like the butterfly itself in motion, if you follow me. But that's personal preference for you
