Every image that I process has consistent horizontal lines through the whole image. Wish I knew how to attach a photo to this message.

Hi, this could be your GPU, are your drivers up to date
Hope this helps
Thanks! I’ll check on that.
I am also having these issues too. Boxes and lines on my photos.
Are you seeing a grid pattern (horizontal and vertical lines), or horizontal lines only?
If you see a grid pattern, please send the original file you are processing so I can try to reproduce the issue. You can securely submit your image(s) to my Dropbox using the link below. Please be sure to send me a note to let me know you sent something.

If you see a horizontal line only, it’s a driver issue. Please send your system profile.

As @andrewlankester said, this is usually due to a NVIDIA driver issue. Here’s the latest driver for your NVIDIA Quadro RTX 4000.
Please install that and let me know if you are still having issues with the artifact.
Yes, it’s horizontal lines only. Thanks very much for the info. I’ll have my IT specialist help me install the new driver. I’m rather clueless!
Sounds good! Just let us know here once you’ve had a chance to update the drivers 
Thanks for your help Preston. Yes, the driver update solved the problem!
