I recently found out that r9 390 is not listed as having 4k (3840 × 2160) resolution on 1920x1200 monitor? Could anyone care to explain me why is that? r9 380 and r9 285 have that option.
VSR is hardware based and cards that are GCN 1.1 go up to 3K. They could support software implementation like Nvidia but thats probably in the future.
I just recently found this option on CCC, is it missing from the tab to enable or you're not seeing the resolution as an option after enabling?
One thing to also consider - it could be a ratio option. 1920x1080 evenly ratios for 4K, 1920x1200 doesn't.
Not seeing it at my screen resolution settings. And r9 390 isn't listed as well on amds site as having 4k on 16:10, even though 380 does
Seems that only GCN 1.2 cards (Tonga, Fiji) support 4K VSR
Oh, well. That's kinda dumb.
this is ridiculous, the r9 390 is far more powerful than a shitty r9 380. So AMD has been BSING about the r9 390 not being a remake of an r9 290, im here all happy and crazy to play my 4k tv at 4k resolutions but to know that the r9 390 isn't fully capable of even doing VSR thats sad really.... im so pissed this is ridiculous i spent 700 dollars on my 2 gpus on crossfire set up. what a shame seriously, a r9 380 being able to VSR but not the r9 390 WOW just WOW
thanks for the answer though very informative.
R9 390 will play 4K just fine with a 4K Monitor via Display Port or 4K TV (HDMI 1.4) 4K @ 30Hz or buy a DP to HDMI 2.0 adapter to get full 60Hz. VSR is only for rendering higher resolution then your monitor support.
Where is there a real dp to hdmi adapter i have tried many and are all lies.
This is the real one: DisplayPort™ 1.2 to HDMI™ 2.0 4K60Hz UHD Active Adapter - Connect and do more
Thank yoy How sure are you ?
Yes. This one came after Fury X card and was designed for 4K 60Hz. Other adapters as far as I know dont work.
i checked on the websites it seems like they dont have it in stock, i have been looking everywhere lol. Thanks though.
Yeah, you need the right adapter and then you can skip the "VSR" and just actually display actual 4k res without needing to "upscale" it. Might contact your GPU manufacturer to see if you can get it from them. VSR is basically just meant to emulate 4k on a non 4k monitor; in a nutshell it lets a game actually render the 4k, and then downscales it to display on a 1080 monitor, if your hardware is actually capable of displaying the 4k to begin with, then VSR is a completely unnecessary function and thusly is irrelevant to its inclusion.
Even if you had a 1080 monitor instead of a 4k screen, from my experience some games don't necessarily like running with it (Metro 2033 Redux springs to mind, though it's got its own finicky display setting issues) and doesn't make enough of a difference in my games to warrant the FPS hit, I'd rather run them at 1080 on ultra. I expect some of these issues to always be present when you're trying to make something render onto a display that shouldn't really be capable of rendering it, so the fact it works at all is pretty amazing, just know that since you have 4k, it's a completely unnecessary function for you and even if you didn't, I wouldn't miss it much.
