Zoom and Scaling: Making Your Browser Session Readable

Short answer: If everything in your browser session looks tiny, open the Ctrl+Alt+Shift menu and change the display or zoom setting there — not your browser’s own zoom. Browser zoom scales the picture and makes it blurry; the session setting changes the resolution and keeps it sharp.

Applies to: Browser access · Infosaic cloud desktops

A browser session shows you a picture of a Windows desktop. How big that picture is, and how big the desktop inside it thinks it is, are two different things — and that is why the obvious fix often makes matters worse.

Press Ctrl and plus in your browser and the picture is enlarged, pixels and all. Text that was small becomes large and soft. Change the setting inside the session instead and Windows redraws everything at the new size, crisply.

How do I make the text bigger in my browser session?

Three approaches, best first:

Change the display setting in the session menu. Press Ctrl+Alt+Shift, find the display or zoom control, and adjust it. Windows redraws at the new size and stays sharp.
Change scaling inside Windows. On the cloud desktop, open Settings → System → Display and raise the scale percentage. This makes text and icons larger everywhere and is the right fix if you find everything small.
Use full screen. Press F11 in your browser. Losing the tab strip and address bar gives back a surprising amount of usable height.

Browser zoom is the last resort. It is instant and it works, but the result is soft, and it can also push part of the desktop out of view.

Why is part of my desktop cut off?

This is the other half of the same problem. The session was sized for one window, and then the window changed — you resized the browser, rotated a tablet, or plugged in a different monitor.

Reconnect after resizing. The simplest fix. Close the tab and open the session again, and it will size itself to the window you have now.
Check your browser zoom is at 100%. Press Ctrl+0 to reset it. A zoom left over from another site is a common cause.
Go full screen before connecting rather than after.
On a tablet, pick an orientation and stay in it. Rotating mid-session is what leaves an unreachable strip at the edge.

If sharpness really matters — detailed spreadsheets, drawings, long days of reading — connect by RDP instead. An RDP client negotiates resolution and scaling with Windows properly, and can use a second monitor. See browser access or RDP.

On a phone or tablet

Touch devices behave differently, and the rules are simple:

Pinch to zoom in on something fiddly, then drag with two fingers to pan.
Work in landscape. Windows dialogs are laid out for width, and portrait wastes most of the screen.
Raise the Windows scale percentage on the cloud desktop if you use a tablet often. It makes buttons big enough to hit with a fingertip.

Questions and answers

How do I zoom in on my cloud desktop in a browser?

Use the display or zoom control in the Ctrl+Alt+Shift menu, or raise the scale percentage in Windows display settings. Both keep the picture sharp.

Why does everything look blurry when I zoom?

Because browser zoom enlarges the picture rather than redrawing it. Change the setting inside the session instead and Windows renders at the new size.

Why is the bottom of the screen cut off?

The session was sized for a different window. Reset browser zoom with Ctrl+0, then close and reopen the session so it fits the window you have now.

How do I go full screen?

Press F11 in your browser. Doing it before you connect gives the session the whole screen to size itself to.

Should I change scaling in Windows or in the browser?

In Windows on the cloud desktop, if everything is too small. That setting follows you to every device you connect from.

Does browser zoom affect other people using the same desktop?

No. Browser zoom is local to you. Windows display scaling, however, is a setting on the desktop itself and everyone signed in will see it.

Why is text sharper over RDP?

An RDP client negotiates resolution and scaling with Windows directly, so text is rendered at the right size rather than scaled after the fact.

How do I make things bigger on a tablet?

Pinch to zoom for a moment, and raise the Windows scale percentage if you use a tablet regularly. Work in landscape.
