Thanks for the help.
If i understand you properly you mean something like stress testing a CPU for stability. There is no really stress test that can perform that operation that anyone knows of right now but you can take a darker grey or pail bluee background and set it to the background of your screen. Look closely and you may see lines or ripples in the screen. The level of intensity of these lines or ripples gives you an indentation of how well it is running. If you don't see any good for you.
If you do just setting a custom resolution in the NVCP has been found to be the lesser quality way of doing this. This is because it is still registered as a "custom refresh" and not something native(meaning it wont work with some games). It is also better to use CRU because you can reduce the pixel clock further with it by setting your timings to LCD reduced or even doing it manually. This will reduce the "stress" or strain you are putting on the cable which will make the refresh more stable.
Another way of telling how well it is running is setting the screen to an all white background. Check the uniformity level from one side of the screen to the other. If there is a big difference then you are not doing very good and you could very well use some betting timings or a better cable. If you see no difference from one side to the other you are good to go.
Let us know how it goes in the club thread. Also any further questions you have please post them in the thread since we are getting several Qnix and Xstar based threads going on which can dilute the effective information. Having everything in one thread will help others later find it.
