I teach you how to widescreen (21:9) native 16:9 monitor

post #1 of 12
Thread Starter 
I will teach you the steps to create a ~21:9 (actual 64:27) ultra wide resolution on native 16:9 display

What are the advantages of this?
To test what ultrawide feels like.
To lower the resolution on a native 4k display for higher FPS.
To maintain 1:1 pixel mapping.

Fun Fact: A 40" 4k display ran as an ultrawide will have a higher resolution and a larger screen than an actual 34" 3440*1440 ultrawide display.

Step 1) Open NVIDIA Control Panel and click "Customize..."



Step 2) Check box "Enable resolutions not exposed by the display"



Step 3) Click "Create Custom Resolution"



Use following resolutions

4k Ultrawide: 3840x1620
1440p Ultrawide: 2560x1080
1080p Ultrawide: 1920x810

Step 4) Aspect Ratio should be set to either "Aspect Ratio" or "No Scaling."

Should be same to do 3440x1440 as well with black border all around to maintain 1:1.

40" 4k is same ppi as 34" 3440x1440 ultra wide.

Anyone have an idea how to do this with an AMD card? Specifically change the resolution while maintaining 1:1 aspect ratio?

Just guessing, but perhaps CRU would work. Also make sure the TV/monitor is in 1:1 mode if it supports that option.

Try this:


1 - Right click the desktop and open the AMD Catalyst/Vision Control Center.

2 - In the upper-right corner, select "preferences". Make sure "Advanced View" is
selected.

3 - From the tabs on the left-hand side, select "My Digital Flat-Panels."

4 - From the list that drops down, select "HDTV Support (Digital Flat-Panel).

5 - There should be a list of "HDTV modes supported by this display." Choose the one relative to your monitor's native specifications. Since my monitor's native specs are 1920x1080 @60hz, I choose "Add 1080p60 format to Display Manager (NTSC)."

6 - Click the green apply button.

If you now see one or two resolutions listed in the "Predefined and Custom HDTV Formats" section, you may be ready to go. Open the game and see if your native resolution is now listed.

If you're still not seeing anything, or if you'd like to add a new resolution, continue on.

7 - You should now be able to click the "Add" button next to the list of "Predefined and Custom HDTV Formats." Go ahead and click it.

8 - From here, you can create a custom resolution. When you're done, click accept.

9 - Click the green apply button again.

Tried this but it wouldn't let me go higher than 1080p. I'll try it with the utility above and update. Thanks anyway.

So I tried out CRU and it worked perfectly! I created a custom resolution of 3840x1620.

Tried it on a few games (Witcher 3, CS: GO, BF 4) and it worked flawlessly. The best part is that I can run the desktop in full 4k but have access to that resolution in-game for ultrawide mode. Nice boost in fps too. Thanks for all the help in this thread!

Thanks for the tip!!! I was waiting for an ultrawide 144hz gsync monitor, but now I'm just going to get a swift. This works better for me since I'm not gsming all that much and I'll have the extra vertical pixels when I need them.

Does the ultra wide resolution on a 4k monitor works only in windowed/borderless mode in games?
So far that's how i can only get it to work.

I would like an answer on this too. Since I returned my X34 I'm thinking about jumping on the Crossover 404K boat so this is fairly important to know for sure. Does it depend on the scaler in the monitor?
