I remember when there were comparisons of video quality and enhancements between ATI & nvidia, and results of an "HQV" DVD quality test for multiple cards. I've seen no mention that AMD, in their drivers since 7.5.1, have cut off detailed settings for video - you can't combine high sharpening and dynamic contrast, for instance. And they even now don't let you control the overall brightness, contrast, and gamma. They refer you to an MS thing in Win 7 where you set the brightness on your monitor. Well, ever monitor I've had set to 100% brightness still needed an adjustment at the video card to bring out the shadow detail.
The enhancements are great - I run my R7 240 on the old drivers at 100% sharpening and dynamic contrast on, affect web video, etc. DVD's in Media Player Classic look like something much better, and 1080 looks 3D. It only works on certain players, though. It works for Flash mp4-AVC. I've always wondered if it would work on everything in Linux?
I see that the cheapest nvidia with the latest enhancements is the GTX 1050. I'm wondering if it can sharpen the new YouTube? I have to use a Firefox plugin to force YouTube back to Flash to get the sharpening.
I wish reviewers would get into that stuff, and for each card.
I'd love it if reviewers of video cards would attend to these things.
