iPhone 11 – Uneven lines and Low Quality

#1 · 25/08/2026, 19:05

Hi,

I’m experiencing an issue with my iPhone 11 as my secondary monitor where the image rendering is having some issues.

Some lines appear normal and some lines appear very thin, and text becomes indistingushable at times (Shown in the screenshot), but all appears normal on my regular desktop monitor.

Device / Display settings:

Viewer Device: iPhone 11

iOS version: iOS 27 Beta 5

spacedesk iOS viewer version: 2.1.6

spacedesk Windows Driver version: 2.2.30

Resolution: 1792 × 828

Refresh Rate: 60hz

Windows Display Scaling: 100%

Viewer image quality: Maximum

Encoding: Hardware Encoding (H264)

==Troubleshooting already performed:==

I tested all encoding settings but they didn’t work

I tried it at native resolution, 100% scaling, 60hz, but the issue still happens

The issue is also visible in a screenshot

I would appreciate if this could be investigated.

Thank you!!

Hi @faulty,

For further analysis of the issue, please send us the logs of your Primary PC by opening the spacedesk Driver console as administrator and clicking on Diagnostics then follow the steps below:

1. Download the DebugView.
2. Check the Diagnostic Collection box.
3. Reproduce the issue e.g. by connecting the spacedesk Viewer app.
4. Uncheck the Diagnostic Collection box.
5. Click “Save All Information” button (this might take a while to finish).
6. Compress/Zip the folder which contains the logs, then attach to your next reply to this post. If the folder exceeds 512kb, you may upload it to Dropbox or Google Drive then include the download link on your next reply.

Thank you.

Hi @faulty,

This is expected since spacedesk does not exactly match the quality of a physical display even on the maximum quality setting. You may try lower resolutions to see if the image quality is better. Thank you.

I tried doing lower resolution qualities (1366×768, etc), but there was no effect whatsoever and the problem still continued.
