Just to make it clear, it's about GTA IV.
I'm having some trouble with video output on my Playstation 3. I bought the console back in 2009, and everything worked perfectly, but one day, while we were cleaning the house, my brother accidentally pulled the HDMI cable and ripped it in two parts. So, we bought a new HDMI cable (which was a lot cheaper) and since then, the video output sucks - the resolution is bad, car and object edges are pixel-ish and also while going fast in a car, the game lags a bit.
I'm guessing that HDMI cable is bad, because it was cheap, but here (http://reviews.cnet....e-buying-guide/) they say the price doesn't matter and that all HDMI cables are same and output the same audio and video quality. That cheered me up a bit and I thought I could solve this without getting an expensive HDMI cable, so I started looking for fix on internet.
Somewhere in V forums, I read that people have same problem with GTA V, and they say downscaling the output resolution from 1080p to 720p should fix it. So I tried it, but it didn't work. Tried it with 1080i, too, and it downscales to 720p ingame itself, but still nothing.
What else can I do? Any suggestions?
