Wondering if anyone has tips? Have several questions.
- Read on forums that PC Mode doesn't output 0-255 even when selected, since the Nvidia Control panel only applies it for the Video. Came across a registry hack but haven't messed with that yet. I tried compensating for blacks with using Low Dark adjustment (forget the setting name) but that's only available in I think the Standard mode on PC.
- Speaking of...Entertain and Standard being the only 2 settings in PC mode, which is better? Entertain seemed more vibrant, but I don't know how much I'm losing in terms of color accuracy. (For what it's worth I always end up on Warm 1 in other settings, even though I know this isn't the most accurate, it seems more accurate to my eye).
- Game mode seemed too harsh. Jaggies and colors felt way too overblown. I tried messing with the contrast/backlighting but didn't have enough time tonight. Although I heard Game Mode is more accurate?
- Nvidia Control Panel's setting of RGB vs the other setting (YcBcr?) - which of these is better to choose?
- Do you guys leave sharpness at 50 (which I understand is the equivalent of 0 at other modes)? Or do you take it down notch. Wonder if that was contributing to some jaggies/edge play more than usual.
Kind of feel defeated but it's 4 am lol.
madvr comes with a little tool that can adjust the nvidia HDMI output ranges with a click.
Entertain is terrible, I wouldn't even consider it.
I'm not aware of any reason to output YCbCr 444 instead of RGB.
For Game Mode, Sharpness=0 is no sharpening; for PC Mode, Sharpness=50 is no sharpening.
PC Mode displays the RGB color input without lossy conversion through YCbCr 4:2:2 for processing (we discussed with some test patterns a ways back). So the color is more precise, but not necessarily more accurate (that determination requires a baseline to compare against). PC Mode is significantly less saturated than other modes by default, but I lack the expertise to speculate whether that is more or less "accurate". Subjectively, I think the more saturated colors look better for console gaming at least.
I actually tried to get used to PC Mode for over a week. One reason is the effect of lossy YCbCr 4:2:2 conversion is actually visible without a microscope in my Win7 HTPC's wallpaper. The other reason is that the F7100 automatically disables PC Mode when switched to 1080p24, which translates to convenient automatic switching for video in my setup -- way nicer than the ridiculous 5 step Game Mode toggle.
Having said that, I recently switched back to Game Mode because it just looks way better to me. Particularly ambient glow kind of effects (from flames etc) were lost almost entirely in PC Mode.
I'm curious how PC Mode will compare when calibrated to the same target as non-PC mode. If that showroomcal guy really does a F7100 calibration we might find out. (I checked his thread a couple days ago, seems like he has been on vacation.)
