Precision 7530 & Precision 7730 owner's thread

Would the hdr400 4k panel from the 7540 work in the 7530?
My 7530 has the 6bit fhd panel and it has really bad colors.

 

Anyone else here have Lightroom Classic and a 7730?

The 8.4 update to Lightroom doesn't seem to be seeing the Radeon Pro WX 4150 in my 7330 -- only the Intel UHD Graphics 630 -- so performance in Lightroom is sluggish compared to 8.3.

Is there anything I can try to get Lightroom to "see"/use the 4150?

 

Is it generally safe to install new drivers directly from a video card manufacturer's site?

I see that AMD released new drivers fro the Radeon Pro at https://www.amd.com/en/support/prof...-pro-wx-x100-mobile-series/radeon-pro-wx-4150.

I'm hoping that addresses the issue I'm having with Lightroom.

 

Can't speak for AMD but I've done this for both NVIDIA and Intel, and it is "usually" fine. Worst case, just roll back. The easiest way to do this is probably to just make sure that you set a System Restore point before installing the driver from AMD.

Nowadays I normally suggest to stick with what Dell has put out unless you have a specific need to do otherwise. In that light, maybe consider rolling back if the new driver from AMD's site doesn't fix your problem.

 

Okay, I just installed the new Dell-specific drivers from AMD. That did not solve the problem with Lightroom. Lightroom is only seeing the Intel 630 adapter. If I disable the 630 in Device Manager, only then does Lightroom see the Radeon Pro.

I've posted in the Adobe forums about this. Not sure if this is a Dell/Intel/AMD driver issue or an Adobe issue.

 

Try this with the Intel graphics adapter enabled.

Windows 10 settings.
Click "System" -- you should end up in the "Display" area.
Scroll to the bottom and pick "Graphics settings".
Select "Classic app" from the list and then "Browse" for the Lightroom executable.
After you select it, pick "Options" and then set it to the "High performance" GPU.

 

DUDE! That was it.

I set that up a while ago when the version of Lightroom that I use was located at \Adobe Lightroom Classic CC\lightroom.exe. It was already set to high-performance.

However, a few weeks ago Adobe renamed Lightroom Classic CC to just Adobe Lightroom Classic and it turns out they changed the folder name as well. The executable is now located at \Adobe Lightroom Classic\lightroom.exe.

I deleted the entry for the previous folder name, created one for the new folder name, setting the entry to High Performance and now Lightroom detects and utilizes the Radeon Pro.

Thanks very much for your suggestion. This will save me time every day.

 

So, more strange behaviour.

The Lightroom/Illustrator/Photoshop power-saving 'feature' works only until the notebook sleeps. Afterwards, upon reawakening, power draw skyrockets to 30-35 W, even with all 3D applications closed (and 12 W on the CPU alone—the CPU might be sending draw calls to... what? I have no idea). Maximising Lightroom, oddly, drops the power draw to around 18 W.

On Linux, when the SDDM service (I use SDDM) is disabled, power draw is equally bad, at around 30 W. When it is enabled, Arch boots to a black screen (I have to change TTY using Ctrl-Alt-F2 to be able to log in), but power draw is at a gentle 8-10 W, and I can make the battery last 12 hours or so.

This is beginning to get exasperating.

 

To everyone still having audio latency issues post bios update, if you have an nvidia gpu make sure you select "prefer consistent performance" in nvidia control panel. I get perfect latency performance with this bios update and never get over 750 microsecond interrupts in latencymon after 5 minute+ tests.

 

Ok good to know I will try it but how about the power draw in this case. I suppose that it will be much higher than without this option
Edit.
A have tried but the same latency sometimes higher than 20000us. But normally i use integrated CPU graphic processor so i think that this only get an effect if i switch it off permanently. Maybe similar option is somewhere in integrated graphic processor settings?
