Universal Modeline Calculator Reviews

Perfect for hacking my HDMI 1.3 output for rudimentary 4K support. ^^

It's a lot more powerful than gtf and cvt because it lets you specify what pixel clock you want and lets you adjust other parameters. I'm having some trouble... maybe you can help. I'm using a Sunix DPH2000 Displaylink > 2xHDMI adapter. It uses unusually low pixel clock rates. Using the modeline it provides below, for 59.90 I'd like to be able to construct my own modeline for 59Hz for example, or 50Hz even. (It runs a little hot and seems to be cutting out out when running at it's max supported res and I'm hoping a lower refresh rate (pixel clock) would help) ... though the problem could also be my HDMI > LVDS converter boards which are also running hot. I've ordered heatsinks for all these things as I'm in a very hot country. Those numbers that come after 3840 and 1200 remain a mystery to me. Somehow they make sense in conjunction with the pixel clock. Is it possible to configure umc to produce the same modeline as the 3840x1200 @ 59.9Hz modeline below? if so, hopefully I can use the same settings to produce 59Hz and 50Hz to try them out. Here are some examples of how it differs from gtf and cvt $ gtf 3840 1200 60 # 3840x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 386.31 MHz Modeline "3840x1200_60.00" 386.31 3840 4096 4512 5184 1200 1201 1204 1242 -HSync +Vsync $ cvt 3840 1200 60 # 3840x1200 59.92 Hz (CVT) hsync: 74.60 kHz; pclk: 386.75 MHz Modeline "3840x1200_60.00" 386.75 3840 4104 4512 5184 1200 1203 1213 1245 -hsync +vsync #I've composed modelines from Sunix DPH2000 EDID offerings (untested) Modeline "3840x1200_59.90" 295.8 3840 3888 3920 4000 1200 1203 1209 1235 +hsync +vsync Modeline "1920x1200_60.00" 154 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync Modeline "1920x1080_60.00" 148.5 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync Modeline "1920x1080_59.90" 148.4 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync Modeline "1920x1080_50.00" 148.5 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync
