[Discontinued][17-09-22] RatRefresh - refresh rate switcher, stops LCD tearing

<< < (8/31) > >>

Hi, I've been very busy lately, we are about to remodel the house and add a few meters as well. So we are busy with constructors and the like. Also it's carnaval here  :cheers:

In the next few days I'll try to work on the tool again. Currently I've implemented a way allowing you to select a monitor and it'll read the edid and modify it, whichs means you don't need the edid file and registry. I'm not too fond of it though, so I'll redo that I suppose :)

Rataplan626: I got advanced mode working in IntelAddCustomMode. I don't think it's adding the decimal part of the refresh rate but give it a try anyway and let me know your results.

You can cut/paste this command line:

--- Code: ---IntelAddCustomMode.exe mode=adv verbose=true hactive=1920 hfrontporch=48 hbackporch=80 hsyncwidth=32 vactive=1200 vfrontporch=3 vbackporch=26 vsyncwidth=6 vscanrate=59.150
--- End code ---

Thanks for this. I've been taking a look and can confirm it works perfectly as intended.

I was able to get games to launch at the correct refresh with GameEx and MAME for every game I tried.

Unfortunately GameEx will not reinitialize the direct3d device after return from a game. It produces an out of memory exception. It does not like the device being enabled/disabled and I was unable to work around this.

Still, very nice work and again I can confirm it does work for me.

A couple of thoughts on other options rather than resetting the video.
1. Try putting the monitor into powersave mode.
2. Try resetting the actual specific device rather than the whole video system.

@tspeirs; thanks for the reply, glad to hear it works. I am currently working on the tool again, I've had a couple of really rough weeks and haven't had any free time at all. I'm still working to get it to read the new edid values without restarting the driver, and I am implementing a better way to select the wanted display from commandline, rather than supplying that EDID file (which will always be optional, as one might just have some different edid, who knows).

Hi Rataplan626,

I've been extensively searching through the web for something similar to what you seem to have achieved  ;)

... and to be honest, the main reason for me to join this forum was to be able to speak with you  :)

Since I cannot (maybe because I'm new) leave you a pm, I'll ask you something right here:

- first of all, is it safe to run a 'custom' non standard refresh rate on a general LCD monitor ?
... as far as I know, on digital hw, worse case scenario is the monitor not picking up the correct synch ... but I could be wrong  :-\

- second, what is the granularity/stability achievable when dealing with refresh rates ?
... I mean, if my hw says it can go from 30Hz to 60Hz what are the chances I can go 59.59hz stable, for example ?

- third: how much all the above is hw dependant ?
In other words, is it possible a specific monitor/brand won't allow me to play around at all ?

Cheers  :)
