Problem with Fullscreen Resolution in Mono Game - c#

a couple days ago I started game developing in MonoGame with Visual Studio 2017 and porting my code which i wrote in WinForms to MonoGame. Now I have a problem with the fullscreen mode. I searched the internet and the only thing I found out is that it depends on the resolution the monitor has.
In the default window mode of the application the screen looks like follows:
Now when I switch to fullscreen mode - this happens:
Now my problems are:
One can not see it on the picture because I used the print button and pasted in to paint but the image is largely strechted.
The right part of the screen is cut off
the sprites are moved to the top.
I'm using
graphics.ToggleFullScreen();
Is there a way to keep the original status like it is in window mode? Maybe to put flexible bars for a 4:3 mode and keep the sprite positions? My positions are fixed. So use something like
spriteBatch.Draw(Params.CUR_SPRITE_P1, new Rectangle(Convert.ToInt32(POSITION_P1.X), Convert.ToInt32(POSITION_P1.Y), 750, 476), Color.White); for the player position and the screen (to implement scrolling).
Or maybe adjust everything in full screen mode bu keep the positions of the sprites on different screen resolutions...
Thank you a lot!

Ok after searching and searching I finally found an answer:
var scaleX = (float)ActualWidth / VirtualWidth;
var scaleY = (float)ActualHeight / VirtualHeight;
var matrix = Matrix.CreateScale(scaleX, scaleY, 1.0f);
spriteBatch.Begin(transformMatrix: matrix);
This has to be put in the Draw()-Method.
My virtual screensize was 800x480. I tested it with my Monitor size 1920x1080 and this did the job.

Why my Canvas is not on same positions as on my device?

I hope I am not too boring because again I have one dumb question.
I have made my game near till end but now I have one big problem. My images , text etc in my Canvas panel are not display correctly on all devices.
I made the game and it looks perfect on unity. Then I build the same game to my Galaxy S8 Device and i realized that some images are out of the screen in other words I can not see some images in corners or some text .. That means my canvas settings are not correct ..
This is my canvas settings.
When I change UI scale mode to constant pixel or constant physical size It doesn't show properly even in unity or on phone seems like he zoom in automaticlly too much. I made the best settings for UI SCALE MODE - > Scale with screen size, but on some devices it doesn't show up correctly ( it shows with little errors like corner text is not shown because it looks like he is outside of screen)
I hope someone has solution for this.
Here is my general settings of canvas, which i always use and never got any issue in positioning.
Also when you put any object, RectTransform's value(marked in following image) is not set properly then it will go outside of screen.
For more details see : https://docs.unity3d.com/Manual/class-RectTransform.html
Also you can check different screen ratio from unity and even add new to it and test.

Build android app as a unity stand-alone (for use on a PC) while maintaining correct aspect ratio

I am attempting to build my Unity Android app (1080 x 1920 res) so that it can also run on PC (1920 x 1050 res). To do this, I need to fit vertically to the computer screen while maintaining the correct aspect ratio. I'm nearly there.
I'm using the following code to scale my app resolution down to fit the vertical 1080 of the monitor (android vertical 1920 down to monitor vertical 1080):
#if UNITY_STANDALONE
Screen.SetResolution(608, 1080, false);
Screen.fullScreen = false;
#endif
popUpConfirmRemove.enabled = false;
This works for the most part (after I manually set the pivots of each gameObject corners of the that transform). However, I have a scroll rect UI element, that doesn't scale correctly! That is because there is a vertical layout group on the scroll content that automatically adjusts the pivots.
When I build scale my app to fit on PC, the scroll content doesn't adjust properly.
I would love some help with this!
How do I scale my Scroll Rect - Vertical layout group contents?
Thank you
Have you stretched anchors to full?
Use cntrl key on anchor selection and try the last option.
Try setting the CanvasScaler to "Scale With Screen Size" and set your reference resolution to match your Android app (1080 x 1920) so all UI layout calculations are done to that target resolution. If the aspect ratio is the same it shouldn't matter what you set the Screen Match settings too.

C# Setting cursor position - different results with WinForms and WPF

I have a strange problem. I am trying to set the cursor position with WPF. So far so good. The problem is the following:
On my computer screen (1920x1080, 100% windows scaling) everything works fine, but on my surface laptop (3000x2000, 200% windows scaling) I have run into some problems. Because of the scaling factor the "new resolution" is 1500x1000 (because of the 200% every pixel is "twice as big").
When I set the cursor to 750, 500 with WinForms the cursor appears in the exact middle of the screen but when I set the cursor position to the same point with WPF the cursor appears in the upper left section.
So apparently WinForms uses the resolution 1500x1000 and WPF uses the resolution 3000x2000 when setting the cursor position...
Why are they using different resolutions here? This doesn't make sense to me. Because when I am reading the ScreenWidth and Height with
System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width // and Height, WinForms
and
System.Windows.SystemParameters.PrimaryScreenWidth // and Heigth, WPF
both are showing 1500x1000.
Can anyone help me? Maybe it is just a WPF/WinForms difference?
Code to set cursor:
Cursor.Position = p; // with imported System.Windows.Forms;
// or (tryed both)
[DllImport("User32.dll")]
private static extern bool SetCursorPos(int X, int Y);
SetCursorPos(p.X, p.Y);
First post so please don't kill me!
I am not an expert in this topic, but maybe:
WPF uses vector graphics to render things, and has a native support for scaling. If you change font size in Windows to 200%, every WPF application will be 2x bigger.
But in WinForms, if you didn't write your application correctly, scaling can ruin your UI.
To avoid this, if you run WinForms app (in Windows 10) it will just use 100% font size and it will stretch rendered image to 200% size. So you can see for example blurry text. If image is stretched - screen coordinates must be stretched too.
But that's just my guess, I'm not an expert at this.

XNA game starts drawing off screen on laptop

I currently have my XNA PC game running in a borderless windowed mode which has worked well until recently on my new laptop. It seems to start drawing a few hundred pixels off the screen to the top left. This leaves a gap at the bottom of the screen and on the right where you can see the desktop below the game. All the mouse coords are accurate to where you should have to mouse over and click on things even though it's just not drawing in the right place.
My older laptop it drew correctly but this new one I just got it seems to be off somehow. I am using David Amador's Resolution class to set up a virtual resolution via:
graphics = new GraphicsDeviceManager(this);
Resolution.Init(ref graphics);
control = Control.FromHandle(this.Window.Handle);
Resolution.SetVirtualResolution(GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width, GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height);
Resolution.SetResolution(GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width, GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height, false);
I set fullscreen to false and then once I create the game screen I do the following to set it to borderless:
Form gameForm = (Form)Form.FromHandle(curGame.Window.Handle);
gameForm.FormBorderStyle = FormBorderStyle.None;
I tried doing "gameForm.Location = new System.Drawing.Point(0, 0);" to try and force set it to start drawing at (0,0) but with my current set up that doesn't seem to do anything because I can set it to (150, 150) and it won't start drawing there. Here is a screenshot from my laptop that shows how it's moved the window and cut off the left and top side exposing the desktop:
Does anyone have any idea why it could be happening now on my new laptop when it hasn't happened on my desktop or old laptop ever before?

Blurry textures after resize on certain computer?

So here's the thing. I made a game in 192x108. Yes, that small. I also made it borderless windowed, and it also resizes and stretches itself to it fits the main screen.
HERE'S THE PROBLEM:
When I start the game on my home PC, it stretches out to 1920x1080 with nearest neighbor and it's not blurry at all, just a pixely beauty. BUT when I start the game on my school PC, it stretches out to 1366x768 and becomes BICUBIC? I even added PointClamp to the spriteBatch.Begin(...SamplerState.PointClamp), but there was NO difference.
So how come it's different depending on the PC I use?
Looks like you can do this for every frame outside of the sprite batch:
GraphicsDevice.SamplerStates[0] = SamplerState.PointClamp;
https://gamedev.stackexchange.com/questions/6820/how-do-i-disable-texture-filtering-for-sprite-scaling-in-xna-4-0
However, I'm wondering if it isn't the sprites that are being scaled, but the device after the sprites are rendered. Hard to tell without more information. Make sure your DisplayMode, ClientBounds, ViewPort, and BackBuffer are all the same width and height as well.
