Title: Tv geometry adjustment
Post by: Yenome on October 09, 2013, 10:08:56 pm

I got my oem remote for my jvc av-32cf36 and started playing with getting a nice square pic in the service menu. my whole point is to just use the tv in a showcase cab. and only for mame games of the 80s 90s. im close but it still a lil off I was wondering if anyone had any tips on what I could use to help speed the process along. I was using umk3 monitor test patterns to help with it but if anyone knows a game with a better pattern or a pc program with good patterns id be most grateful. thought I had posted this last night but I was so sleepy I might of forgot and just shut down the pc.

thanks this should help lots. I found street fighter 3rd strike had a nice cross hatch pattern works really good too. tho I noticed diff games have diff amount of black space around them. like street fight has a cm or two. where killer instinct has 10-20

More recent versions of MAME will allow you to adjust that border on a game by game basis, hit TAB while in the game and look at the slider options.

Thanks guys its looking a lot better still not as great as it could be. still need a power strip compatible video card and a transcoder, just using svideo at the moment. was using component but the colors started to go wonky during tests so went down to s video. plus it easier to get 640x480 with svideo on this tv than I can with component NVidia keeps defaulting it to a hdtv tho it is not.

I wouldn't use Soft15kHz/Powerstrip anymore.  CRT_Emudriver is the way to go:

I use an ATI HD4350, which can be found on eBay for around $20.

so did you write a new guide on using emu_driver and an ati card? do you still use the transcoder in the loop I think I read on one of your other post recently that you was still using it.

Yup, transcoder is still used.  Check the latest post in the Newbie TV thread, second link in my signature, for an update on transcoder choices.  The switch to CRT_Emudriver is addressed there too, it doesn't change much in terms of what was discussed there.
