i was wondering if a common and cheap radeon 4xxx pci xpress card would get the job done. i never checked the multiple monitor settings in the ati option menues . maybe cloning with subd for screen1 plus dvi-sub d adapter for screen 2 will work .
ps. : arcade + scart : i picked some old grundigs with 5xxx chassis and analog adjustments . they are as close as it can get to my philips valvo vcc chassis build in several arcade cabinets. very nice appearence . first time i tested a st63 650 grundig (a59 philips tube ) with umsa , quality cables and games like battle bakraid i nearly pissed in my pants. the look was 100 % authentic + it synched any ---steaming pile of meadow muffin--- up to rtype .. the only prob with such 20 year old tvs is the weakening of the tubes. they tend to lack sharpness on the edges ( same thing i noticed on some of my philips / valvo bases cabinets ) . it appears fresh or modern philips tubes dont have this prob .
on the other hand i found out that even some digital chassis like cuc 2030 are capable of outputting 256 p . last week i replaced a damaged cuc 2030 of my 25 inch vertical table with one of a backup tv ( grundig st 63 780 ). i have some of this digital models in storage , so i didnt waste my time with reparing the chassis . i knew there have been older " normal " philips tubes and black matrix versions in the same model . nevertheless this one was a surprise. the tube was a black blabla toshiba liscence made by tesla cssr ( very sharp, nice contrast and colors ) and this 2030 chassis revision was able to display 240 and 256 p without tinkering in the arcade osds v- porches setting. most 2xxx cucs are showing missing and or crippled lines on the top of the screen . i would have replaced the broken chassis with a 5360 , but the size was an issue here. there was no way to mount it with the pots in range .
