Question / Help iThinkiNeedHelp with a display issue

[iThinkiNeedHelp]

Hello everyone. I am new to OBS, and this forum, and am looking for some help on a problem I am having.

Log : https://obsproject.com/logs/DgpRB0ryuz5EjwWH

Problem : I am attempting to create some instructional videos and what is displayed in OBS cuts out the top and left inch of the screen (pictures below for reference).
As you can see from the pictures the top part of the icons are cut off and the first Lock icon on the left side is completely cut off.

Equipment : To make these videos I am using a Surface Pro 3 running Windows 10 64 bit OS powering a MiraBox HD Video Capture Card which is then connected to a Linux based machine.

Connection : I have the MiraBox powered by my laptop through the USB port, then a HDMI-DVI cable connecting the Linux machines monitor to the MiraBoxs output, and a HDMI-HDMI cable connecting the Linux machines video output to the input on the Miradox.

When researching how to fix this problem I have tried to do the following
- Fit and Stretch to screen
- Alt + Click to crop
- Attempted many different Base and Output Resolutions (ended up missing the same portion of the screen)
- Tried on a Linux OS laptop
- Ran as Admin

Let me know if any more information is need.
Thanks in advance!

You can select the capture source and resize it manually to fit your screen with the handles.

If your output resolution is not the same aspect ratio as your capture resolution, you'll either end up losing some of the screen or having black bars.

Narcogen thanks for the reply.

I went back and tested a few different resolution combos with little to no change in the cut off portion of the screen. Below I have short clips of each resolution I tested.
I tried test a 4:3 to 6:10 resolution because on my monitor I see block boarders on the left and right, so I assumed I am outputting a 4:3 resolution onto a 6:10 screen. (https://imgur.com/AZBalH9)

The strange thing is that when I switch from the software GUI to the Linux machines camera the image is perfect, see link below.

Hope this info can help narrow down my issue.

Most likely the camera image is just being cropped and you don't notice it, whereas with the app GUI you would definitely notice that parts are missing.

You shouldn't need to guess at the native resolution of your display-- you should be able to see it in your OS settings.

In fact, it's in the OBS log, I should have looked earlier:

09:58:48.218: Adapter 1: Intel(R) HD Graphics 5000
09:58:48.218: Dedicated VRAM: 117964800
09:58:48.218: Shared VRAM: 2147483648
09:58:48.218: output 1: pos={0, 0}, size={2160, 1440}, attached=true


2160 × 14401.5:1 (3:2)

This is your problem. Your screen isn't ANY of the aspect ratios I talked about. It's 3:2.

The problem is that if your screen's native aspect ratio isn't 16:9, then someone is going to see an image that's cropped, letterboxed/pillarboxed, or stretched. The only question is whether you distort your own screen to present a normal image to your audience, or watch a normal image on your screen and let the audience see an image that is either cropped, letter/pillarboxed, or stretched.
