1. We all know that HD movies are mostly 24 FPS. Say, we watch it on 1920x1080 @120Hz monitor, it will refresh it to 120Hz = 120 FPS right? We also know that rendering movie can be done by GPU (hardware acceleration) or by software, is this correct? We don't have to do anything because the monitor EDID supports 1920x1080 @120 Hz. The display processor is also capable of 120Hz at that resolution. We can also choose the video quality is thru the display processor instead of graphics driver (GPU). From all the options we are still well within the DVI-DL bandwidth limit but it has nothing to do with GPU if we select software to render these movies, am I wrong?
2. The supported EDID of this Korean panel is 2560x1440 @60Hz right? So in order for the OS (Win 7) to recognize the panel capable of 2560x1440 @120Hz, we modified the EDID. Now, back to this HD 24 FPS movie, if we let the software to render then send the signal to monitor thru DVI-DL, the monitor will still refresh it to 24 x 5 = 120 FPS = 120 Hz. So is this all we are doing by telling the OS that the plugged in monitor is capable of 2560x1440 @120 Hz?
Let's leave gaming alone, because it's so confusing if we mix it with this DVI-DL bandwidth limitations, because while playing games @200 FPS on a 60 Hz capable monitor we are still seeing 200 FPS on the counter.
If what I am thinking is flaw, please kindly explain.
You only see 200fps on a 60hz monitor if you have vsync off. I have games that report over 1000fps. When vsync is enabled, the refresh rate will not
exceed your refresh rate. Whatever you have it set to. 60. 80. 100. 120. 134. whatever it is.
As for movies, yes. Whether you're watching 24fps, 30fps, or interpolated 60fps, all of them are multiples of 120hz. Which makes it a desirable refresh rate. And once you follow the guide I told you about, then your computer will believe the monitor has a much higher rated actual refresh rate. As you can see here. So don't worry about it. You're thinking far too much of it. Haha. And we've already confirmed the dl-dvi bandwidth limit doesn't come into play as it was for the stated 300mhz, not the upto 537mhz that we run ours on.
Thank you very much for the work you have done. I am sure it's very useful for the community. We should see more users to come up with such guide as yours
Back on topic, I guess we all can give the DVI-DL source bandwidth limitations a rest now. It has nothing to do with it
A bit dissapointed, hoping to hear you say "you're wrong" then I can learn how to overclock TMDS
