are you running amd apu / hardware? DVI and HDMI are the same electrically. Could be driver / software related. Also can some tell me if running a higher DPI affects the Istripper software. This may be why I can see a change. I run my DPI at 115%. Makes all my icons and texts nice and big and clear on 1080p.
Maybe we are getting our gold wires crossed... ;)
Technically, I'm agreeing with you! At 100% on HDMI the image is cleaner and crisp... on a bigger monitor that would look good.
However where we disagree is daily usage (and maybe brand name) the trade up for hard drive space and processor power at 75% is marginal...
On paper, monitor wise our DPI is the same, perhaps the sharper image comes from the fact that my DPI has to cover 2" squared more...
What CPU are you running that gets 75% with 3K. My AMD FX 8320E uses 15% at tops with 3K content. I know any Intel core i5/i7 since Sandy Bridge should be able to match or more likely beat that. Unless totem has coded istripper for better multi-threaded support.
