Mounting LED monitor upside-down (2024)

It'll be fine, whichever orientation you want your monitors to be - it will NOT kill the monitors. In fact, Windows allow you to rotate the screen (90, 180, or 270 degrees): https://www.softwarert.com/rotate-screen-windows-10/

You would want to have a dual vertical mount for this setup, such as these:

The important thing is to check the monitor's VESA mounting holes against the dual vertcial mount's VESA bracket design if it will fit your monitor (specially the one oriented upside-down), as most brackets only rotate 90-degree max. on either direction when the monitor is mounted.

Thanks for the quick reply! I've actually got a quad stand with it, in hopes of adding more in the future. Mounted it up and it works perfectly (well, did, for a moment), although now there's another issue, it appears i can't run three screens at once? AMD control center asks me to disable one before enabling the third, and windows "screen resolution" settings just say settings can't be saved if i choose to extend to the third. However, everything works perfectly if i only run two at a time. Any clue to how i could fix this?

You might be forced to run at least 1 monitor off the DisplayPort video output of your GPU in order to enable 3 monitors at the same time (the 2 using other outputs, such as HDMI or DVI or VGA, in your GPU). Does your GPU and monitor/s have a DisplayPort?

Another method is, if your CPU/motherboard allows it, to run off the other monitors via integrated graphics (at the same time using your dedicated GPU), unless your CPU/Mobo BIOS doesn't allow it.

It's got what i'm pretty sure are two mini displayports (that's a thing, right?), in addition to the hdmi and dvi (in use). There's another dvi on the panel right below it, which i'm currently trying and failing to use (it however works if i disable a monitor using one of the other outputs).

I tried the BIOS method following a youtube tutorial, but i couldn't find the right settings to change for it, so i think that doesn't work with my system.

The monitor itself has dvi, vga and hdmi, but if the displayport route is necessary i'm sure i'll manage to find an adapter.

Are there no other ways to force this beast into submission using only the hdmi and dvi outputs?

As far as the AMD GPU issue in enabling 3 monitors at the same time, the use of the DisplayPort (for at least 1 of the monitor) is the common solution. What's your actual GPU (model)? Also, what's your CPU and motherboard (model)?

If you decide on using the DisplayPort output in your GPU, make sure you get either the DisplayPort-to-HDMI or DisplayPort-to-DVI-D active adapters (active, since your monitors are not native DisplayPort monitors), as these will not necessitate convertinig digital signals (DP, DVI-D, HDMI) to analog signals (VGA).

The GPU model is the HD 6800, CPU is Intel i7 870 and the motherboard is (i think) intel dh55hc

It's a pretty old machine by now

Yup, just what I've thought. The old links I posted in my previous reply (as I assumed you had an old setup before your reply), would be specific to your situation. Resolved it using an active DP-to-DVI or active DP-to-HDMI adapters. Then, enable first in control center before windows detects them.

Here are some other links with the same HD6800 GPU you have, having the same problems (resolved also using the above solution, i.e., using the DisplayPort):
