It doesn't make any sense to invest a bunch of money in an expensive monitor or an even more expensive GPU, if you don't tweak the monitors settings.
- Set the monitor/TV & GPU to their default settings.
- Unless your monitor/TV has the possibility to set two presets(like my LG 32"LD350 with 2 Expert settings one day-1 night) set the lighting in the room for when you use your PC the most.
- Set your backlighting to where it's most comfortable.
- Go to LCD monitor test imagesThe Logom LCD monitor test pages and read through first and make sure you understand everything, then follow the instructions.
- You may have to flip/flop between tweaks because an adjustment here can change an adjustment there. for example contrast and brightness- after setting the Black level(Brightness) then going to White saturation(contrast) it can/will make the Black level brighter meaning you have to reset it again, which will, of course, change the contrast a bit and so on and so on. The idea doing it visually without a colormeter is to find the best compromise acceptable for you. The same goes for tweaking the sharpness.
Some might say "Hey I have a Blu-ray movie that came with a tweak section" or like me "I have the HDTV Calibration Disk from AVS forums!", well that's just fine for your Blu-ray player or Home Cinema, but for online gaming or browsing you need to set your monitor for that. It's like with my TV I have slightly different settings for my Blu-ray(1080p) and television(1080i & 720i) because of the differences compression, and also to reduce artifacts. Another reason is that for any differences in types of connections and the difference between a PCs GPU and the integrated graphics of a player.
After you have tweaked your monitor/TV you can then tweak your GPU, being that they are now optimized your GPU/integrated graphics will also have to work less thus reducing lag time and improved performance & resources where it's really needed--online gaming, you tube, or whatever.
