Re: HOWTO: Create Custom HDMI modes

Yes, 15.4Khz. With a HDMI to VGA adapter (Or a VGA666 to output VGA from GPIO) and a VGA to SCART cable (a good cable), you get a 15Khz frequency. Perfect for CRT TV PAL or NTSC . But, i can't confirm if it will work with your HDMI adapter. Few resolutions i use with my Rpi2 and my old CRT TV : 512x...

Re: Uae4arm: Amiga emulator with JIT and DispmanX

Hi all Thanks a lot Chips, for uae4arm, i use it from a long time and i am very happy. I tried uae4arm with my GPIO2SCART on my CRT TV with a 320x256 resolution. (Can be done with a Gert VGA666 and a VGA2SCART / GVA2RGB cable). But, I think you know, on a 320x256 screen , the GUI isn't viewable. Is ...

If i use a HDMI to VGA converter and a VGA to RGB cable, i can use Rpi ont a CRT TV at 720x240x60Hz with hdmi_cvt . But, if i use a Gert VGA666 (GPIO to VGA) abd the same VGA 2 RGB cable, it works b...
