I was very uncomfortable playing GTA4 with blurs on bright day light along with lack of clarity. I searched everywhere on the Web to find a solution for this so that i could enjoy playing GTA4 in my new PS3 console.

Here is how you fix the blurry and dull graphics on GTA4.  Here are the possible solutions i have compiled to get rid of this blur and fuzziness in the game.

1. Download PS3 2.35 system update.

Download here

Something there in the update, that fixes this problem. i dont know what! I installed the update and when i ran the game, those blurs were gone and the graphics were much crisper with vibrant colors in GTA4. Just like magic!

2. Go to Game > Display > Flicker Filter off

Turn the flicker filter off which many people have suggested to remove the blurs.  It may that you may not find this option at all in your game settings. It may depend on the type of TV.

3. Set the display settings to 720p for GTA4. Although 1080i is the most common resolution, the 720p works pretty well for GTA4 .

4. Use a HDMI cable to play GTA4  as it supports superior audio/video quality . If that doesnt help, try using component cables to reduce the blur.

Remember the most important step to fix blurs is the firmware update to enjoy your GTA4
