Precision 7530 & Precision 7730 owner's thread

Pinstripe effect may be caused by a low bit value (6 instead of 8) of the display, or a low PWM frequency. I'd like to know your display model so I could have a check.

 

It's certainly a 6-bit display with FRC. I'll get you a model number when I get home!

 

Could you post a screenshot of the drivers list after a 5 minute test in latencymon? Are you running the test with the laptop plugged in/high performance plan selected? Do you have c-states on or off?

Idle power draw is probably higher with consistent performance selected but it's unfortunately a required tradeoff if you need the real-time latency for recording/using audio interfaces etc.

Quick tip for any music producers using built in audio on this laptop for producing: if you're using asio4all (which you should be), check the box "allow pull mode (waveRT)" in the menu. I'm not entirely sure what this does (I think it increases the priority of audio threads but I could be wrong) but its allowed me to get a crazy low latency of only 2ms in Ableton and a much higher ceiling with adding plugins before crackling occurs.

 

Here's a screencap from hwinfo on the display:

 

That's basically the normal 100% sRGB display, with a digitiser attached.

Haven't received it yet :/

 

Searching in panelook, I found a very interesting thing. LG+15.6''+1080p+touchscreen+IPS+glossy+72% NTSC=these two results. They are both 6 bits without FRC. So it's normal to see "banding" or as you say it "pinstripe effect" on the 6 bit panel.

 

I think that no comment

 

Oh wow, I had just assumed all 6-bit panels used FRC. That's disappointing. "Banding" eh? Yeah, whatever the name, it sucks as a designer.

Unforunately, I need to run at native 1080p for some applications so higher quality 4K screens aren't an option for me. However, with Intel's integer scaling addition in their Gen10 gpus, running 1080p on a 4K screen might not result in a blurry mess anymore. Time shall tell!

Banding aside, can't complain really. Had it running full tilt all weekend at PAX demoing our game. Ran like a champ!

 

I have a 7730/I7-8850/16GB/P3200. I use two Samsung 970 M.2s, one has WIn10 the other Arch linux. I dual boot 'kind of' only one M.2 is turned on in BIOS, the one I want to boot on. I would like to remove the P3200 as I have been unable in ARCH to get video switch to work. It don't need the capabilities of the P3200 in Arch or Win10. There must be something that I would need to install to replace it, would would the be?

Thanks

 

Probably need the pass-through board that mine's coming with, though I'm not sure if it's interchangeable between the 7530 and the 7730, but it's basically just a pass-through for the Intel GPU.
