Since day one my rig has had some issues with chopping. At first I thought it was faulty driver software for my dual Radeon HD 7770's but I have ruled that out, thought it was a poor quality HDMI cable (which it could have been) but now I'm using DVI which has removed about 90% of the chopping from cutscenes and gaming.
I have looked through all of the settings on my display and the video card software and I have come to the conclusion that the chopping is happening because my vertical and horizontal frequencies are not the same, I only get horizontal chopping. I have done some extensive googling and haven't been able to find anything that has helped.
I don't know if the vertical and horizontal frequencies are supposed to be different but I am assuming they're the vertical and horizontal refresh rates and I don't understand why they're different. It's incredibly annoying and puts a hindrance on single player and multiplayer gaming.
Some help with this issue would be marvelous. Thanks in advance.
Here's some information about my setup and if more is needed just let me know.
Displays: Sceptre x270w-1080p (DVI) drivers are installed
LG L227W (HDMI to DVI adapter)
Video Card: CrossfireX AMD Radeon HD 7770 XFX (Dual obviously)
I was under the impression that horizontal scanning rate was something that applied to CRT monitors (since they actually have a moving electron beam), but like I said I'm no expert.
Could you better describe the "horizontal chopping"? It sounds to me like screen tearing which can be alleviated by enabling vertical-sync. Are you using v-sync?
I have tried vertical sync and it makes things much worse.
Here's a video I just took, please excuse everything going on in the background. Feel free to jump to the 30 second mark, if I knew a way to describe what's going on I would most certainly use words rather than recording it with my S3.
