Sorry, I accidentally posted an experimental extract from the MDF, the actual screen mode which is generally used for the monitor is as follows... # 920 x 600 (56Hz) startmode mode_name:920 x 600 x_res:920 y_res:600 pixel_rate:36000 h_timings:72,128,0,920,0,24 v_timings:2,22,0,600,0,1 sync_pol:0 endmode The computer says that it's 50Hz. Is there a simple mathematical relationship between the screen width, screen height, frequency, and pixel rate? >But why are you using such a non standard mode on an LCD anyway, its >going to look rubbish? It's not the LCD Tv, it's the CRT monitor normally with my Iyonix. Standard modes can look very peculiar on it, but the 920 x 600 mode comes out okay. > If you must use it for something increase the >pixel rate to 44400 so its 60Hz. I tried that out, and got a slightly sharper picture at 62Hz, so thanks! How would I make the screen a bit wider without dropping the Hz too much?
