Precision 7530 & Precision 7730 owner's thread

Just received my 7730. Very fast! I have only one complaint and that is with the 4K display. One, I have a bit of light leak in the lower right hand corner of the display. Need to figure out how to lessen the pressure of the case to help it. 2nd, I notice a lot of banding on the display. Can someone else verify? Go here: https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-p/ThinkPad-P72/p/22WS2WPWP72 and let me know if you see horizontal banding in the blue/grey background of the lenovo picture. On my macbook pro, banding is virtually non existent. On the Dell, it is very prominent, makes the display look very low quality. Getting same issue in resolve...may make me return this system if this is the quality of the display...

 

I think that the 6 cell battery is required if you choose a discret GPU dGPU. That's what the configurator said.

 

That's because the display Dell uses is only 6 bits per channel—even though you've got the high-colour gamut one.

That's a terrible pity, honestly. I detest colour banding and time and again, Macs get the display on point, all the time.

 

You have to be kidding me??? They said it was an 8 bit panel. Here's the strange thing. If I disable the integrated gpu, and only use the P5200, it get's better. Especially in resolve. I don't see the banding any more. On the lenovo website, I still see banding, but it is much cleaner and not nearly as bad.

 

A lot of laptops use the panel that's in the Dell: it's the LG LP156WF6 panel that's 6-bit. It's simulated 8-bit with dithering. I might see if I can find a proper 8-bit panel that fits the Dell at some point in the future.

Hmmm. I tried the very same thing, and noticed not much of a difference.

 

Is anyone using the Thunderbolt port and external drive? If so, do you have any benchmarks to share? I am interested in possibly using this as external storage to run VMs in a lab setting and it would 'seem' fast enough to do so.

 

That links to the HD panel not the 4K UHD panel

 

If this banding issue can’t be resolved, I think I might have to return it and look at the Lenovo p72 once it’s released...

 

Oh, right. Perhaps you can download HWINFO, and check what panel you've got, and compare it against the Panelook database?
