I'd rather not buy a pricey 4k monitor - NEED to be able to screen capture windows PC desktop in 4K

Found 2nd Oct 2016
I need to be able to record a windows PC desktop at 4K resolution... My current monitor only goes to 1920 x 1080...

Does anyone know a cheap way to be able to force a monitor to be a bigger resolution (*I don't need to be able to visibly see or appreciate the extra quality) . I'll then be using the footage in a video edit.

We're a 2 man band animation studio in Plymouth and we're trying to fine tune the making of these 'mixed reality videos'... Which involves all sorts and being able to record the screen at a resolution of 4K will ultimately mean we can produce full HD 'mixed reality video'.

If anyones intrigued you can see our mixed reality filming videos and overall progress toward the bottom of this page stormystudio.com/mix…-1/

Any help technical low cost help on the 4K issue would be great. Otherwise I might buy a damaged screen4k monitor off of eBay and see how that pans out.

Thanks

Jon

Why would you screen capture? Just render it at 4k, are you sure you know what you're doing?

If you know a way to stretch a dwarf to be a full sized human then you "MIGHT" be able to figure a way to make a monitor to display 4K when it cant

If it cant;;; then you'll understand that you can't force a monitor to do it, the maximum resolution means just that - maximum

Thanks... we need to screen capture live gameplaybeing experienced by someone in VR, which is output in 4 layers into shown in each quarter of the screen. Foreground, background, etc etc... We then record the whole screen, cut up and overlay each quarter, plus footage we're filming with a live action camera... which makes the mixed reality film..... By the time you cut up a HD image we're left with 960 x 540 .... if we did the same with an origianl 4k image... we'd get a HD image which would be much nicer....

you can record 4k with geforce experience if you have an nvidia graphics card but I think you might need to have a 4k screen.

use your tv as a screen if its 4k?

Thanks that lead to some tiny amount of potential hope. We've got a good Nvidia GPU so I'll investigate their 'shadowplay' options which might just work... at least worth a go before buying a monitor. Thanks for the heads up.

Thanks for the dwarf themed answer... it seems there might be some potential after all.. Nvidia Graphics cards allow for something called shadowplay which records the screen at a higher resolution.... may/maynot quite work...works for stills it seems at the very least...reddit.com/r/n…ay/

You can record 4K easily, however to edit it and display it as you want to do - you'll NEED a 4K monitor, or tv or you can';t see the results, or see if it's worked the way you want

Thanks... and I know what you're saying but I had hoped there was an option.. and it turns out it is possible...if you have the right graphics card... which we do... We've got it working without a 4K monitor.

I've put together a quick tutorial incase anyone else ever needs to achieve the same thing. Could save someone from buying a 4k monitor.

Essentially if you have a suitable Nvidia graphics card, you can turn on a setting called DSR.. which essentially means the image the computer is producing is 4k, which allows you to up your screens resolution to 4k... (*You can't see any extra detail on your physical monitor, if anything it's actually softer)... Though when you record the screen it records in in full 4k.. (We're using free screen recording/streaming software OBS). You can then bring this file into your editing software and work with a 4k composition... (We've also checked the quality on a 5k iMac and it is a perfect 4k capture and is not simply HD thats been upscaled).

So great for us and our current mixed reality filming R&D... but no doubt great for anyone who wants to record the gameplay footage or software tutorials at a higher resolution than their monitor supports.
