Photoshop CS5: Pictures get resized and altered after transfering them to another machine / seen through another screen

(first excuse my lack of grammar and vocabulary, english is not my first language aha)I use photoshop CS5 on a PC with which i paint pictures. I recently got a new laptop on which i noticed that pictures i painted on the PC get altered when seen through the screen of another machine. Not only the size but also the overall saturation of the picture gets modified. Here is an example :Here is the photo of a painting i did on my PC, opened through photoshop. Its is roughly, colour wise, how this picture appears from the screen of my PC, whether i open it with the windows picture viewer, with photoshop, or upload it on the internet (always seen from the original pc screen of course)Now this is how the same picture appears once saved through PNG, seen from a screen that is not my PC screen. The saturation of the colours is obviously different, as well as the size (the picture got... elongated ?) With both images, the size is 1013x1553Why does it appear different between those two screens ? The pixel size is exactly the same ! Now I would understand if the problem was the original screen of the PC on which i drew this picture, if it showed a distorted version of everything. The thing is, iit doesn't. Everything appears fine. (i will still try changing the screen of the PC in a few days, once i get a new screen) This problem is highly frustrating as my paintings end up on the internet, seen a way that i didn't intend for them to be seen, a way i don't even see them when i make them ! With a painting of a landscape, the differences (except for the colours) are minor, but once a human is painted, getting an elongated, desaturated picture is terrible...Is the problem photoshop settings that i have to tweak ? Should i really just change the screen on which i usually paint ? Or is it something else entirely ?Thanks for your time and any help or advice !

First of all is you monitor(s) calibrated with good calibration hardware/software? What is your working color profile? The web is only sRGB so you should convert your image from the working color space to sRGB to upload to the web. I have a calibrated monitor & when I view even a sRGB image in Windows Picture Viewer the colors are off; its the same problem if I save it as a desktop picture. This is a Windows problem, although I haven't tried it lately, possibly they fixed it. But the same image looks good in some of my other picture viewers like FastPictureViewer, Bridge, Lr & PS. As for the change in size, I don't know what the problem might be. I don't use PNG files except in the Snipping Tool in Windows so I'm not sure about that. I don't think PNG files have colorspace written in their metadata, so any viewing software will assume its sRGB & if it is another profile like Adobe RGB it won't display the color properly. Some viewing software doesn't even look at the color profile which means it will display it as if  it were sRGB. Unless the people viewing your image have a quality monitor that is calibrated the colors will be off & look different on each monitor and lighting in the room they're viewing it in. I have a second monitor I use for my tools in PS & it's calibrated too (although cheaper & older), but the image doesn't look the same on it.

Thanks for your comment !

The change of size problem solved itself when i switched my original monitor with a new better one, so there's that, but the colours are somehow still off.
My working color profile is sRGB and i have never calibrated my monitor with any hardware/software. I am only a beginner on "the advanced side" of photoshop and english isn't my first language so technical terms are often hard to grasp. Because of that i don't know what should be default calibrations and settings between my monitor and photoshop. Do you perhaps know of tutorials that explain this ? I saw a lot of them, but they were always about the problems between PS and a printer or between PS and the web. My problem is more about my screen VS other people's screen.

Anyway thanks for your time !

Windows has a "Calibrate Display" under Control Panel>Color Management> then click on the Advanced tab & near the bottom left is a bar "Calibrate display". I've never used this so I can't offer any further help there. I've always used Calibrating hardware that reads the color displayed by its software & automatically creates a color profile that it loads in Windows Color Management. I use X-Rite ColorMunki Display (CMUNDIS). It costs about $109 US dollars. It was a little difficult to set up the first time without help, but their support guided me thru the process & now that it is set up I don't have to do anything, it's all automatic. They also have a cheaper one for $73. Even my $109 version doesn't calibrate the printer too. They have several other models with added features for <$359.  Or you can buy a professional monitor with its own calibrating software for $4000! The X-Rite website has helpful information about calibrating a display & overcoming problems with Windows overriding your calibration for some strange reason. I hope I didn't get too technical. I just viewed some prints in my 5000K light at home & then took them to show my sister in her 2700K light and they looked totally different. It's hard to find consistency in this ever changing world.
