HDMI switch/box with portrait output.

Hey folks.
This is a left field one for you all.

I need a way to take a picture from a HDMI output and rotate it 90 degrees. So it displays in portrait mode on a monitor.

This picture is coming straight out of a CCTV DVR which does not have the option to rotate the image. Right now the only way to rotate an image is using a computer and changing that image out within the desktop display settings.

I need to find some kind of a switch / box that allows a HDMI input signal to be rotated?

Anyone come across anything like this?

Think a finding monitor/ display that has built in image rotation would be easier to locate and a whole lot cheaper than a magic box to change signal to portrait mode

So you've got a CCTV system that outputs in portait mode (e.g. 1080x1920) and you want a device to rotate it to landscape mode (1920x1080) so you can feed it into a monitor that's physically rotated 90 degrees?

That may be tricky to find for less than the cost of professional level kit, what resolution support do you need?

Thank you both for the reply.
Right now iv got a low powered intel NUC running the CCTV desktop application which is rotated and feeding into a monitor that’s mounted in portrait.
That app runs fine on a decent spec machine or laptop. No lag at all. But on a barebone NUC with Windows 10....
With that said the feed out of HDMI is very much in real-time with no lag.
I think you guys are right. Seems the boxes iv come across are between £500-1000 and it will be easier to find a monitor that has this feature built in.
