Na tym monitorze lepiej widać małe litery niż na telefonie.

With screens and display devices, Polish often uses na where English uses on:

• na monitorze = on the monitor / on the screen
• na telefonie = on the phone

This is about what appears on the surface/display of the device, not inside it physically.

By contrast, w usually means in or inside. So w monitorze would sound like inside the monitor, which is not the intended idea here.

Because na here requires the locative case when it answers a question like where?

So:

• monitor → na monitorze
• telefon → na telefonie

The adjective/pronoun also changes:

• ten monitor → na tym monitorze

This is a normal case pattern in Polish:

• na + locative for location

So na tym monitorze means on this monitor.

Ten is the basic nominative form of this for a masculine noun:

• ten monitor = this monitor

But after na (in this location meaning), you need the locative, so ten changes to tym:

• na tym monitorze = on this monitor

So both words change:

• ten → tym
• monitor → monitorze

Widać is an impersonal form meaning something like:

• one can see
• it is visible
• you can see

It does not name a specific person doing the seeing. That is why the sentence feels more general than widzę (I see) or widzisz (you see).

So:

• Na tym monitorze lepiej widać małe litery. = Small letters are easier to see on this monitor. = You can see small letters better on this monitor.

This impersonal structure is very common in Polish.

Because Polish often leaves the experiencer unstated, especially in general observations.

Here, widać already gives a general meaning like:

• you can see
• one can see
• it’s visible

English often needs a subject, but Polish can express the idea without one. So the sentence is naturally general, not specifically about I, you, or we.

Lepiej is the comparative form of dobrze (well), just like:

• good / well → better in English

So:

• dobrze = well
• lepiej = better

In this sentence, lepiej modifies widać, so it means can be seen better.

Using bardziej dobrze would sound unnatural here. Polish normally uses the special comparative form lepiej.

Małe litery is the direct object of widać — the thing that is seen.

The dictionary forms are:

• mała litera = a small letter / lowercase letter
• plural: małe litery

Here it is in the accusative plural, but for non-masculine-personal nouns, the accusative plural looks the same as the nominative plural.

So:

• nominative plural: małe litery
• accusative plural: małe litery

That is why there is no visible change.

It can mean either, depending on context.

In everyday Polish, małe litery very often means lowercase letters, especially when talking about text, typing, reading, or fonts.

But in a sentence about visibility on a screen, it could also simply mean small letters in size.

So the exact interpretation depends on the context already given.

Niż is the standard word for than in comparisons.

So:

• lepiej ... niż ... = better ... than ...

Example from the sentence:

• lepiej widać małe litery niż na telefonie = small letters are more visible than on the phone

This is the normal comparative structure in Polish.

Not in this sentence as naturally.

You can often compare with niż or od, but here the comparison is between two viewing surfaces/devices, and the phrase na telefonie matches na tym monitorze.

So the structure is nicely parallel:

• na tym monitorze ...
• niż na telefonie

If you said od telefonu, it would not fit as cleanly, because the sentence is really comparing visibility on one device vs on another device, not just comparing two nouns in a more abstract way.

Because Polish commonly treats the display as a surface:

• na ekranie
• na monitorze
• na telefonie

So if something appears visually on the device, na is very natural.

Using w telefonie would usually suggest inside the phone, for example:

• mam zdjęcia w telefonie = I have photos in my phone

But if you are talking about how something looks on the display, na telefonie is the usual choice.

The given word order is very natural:

• Na tym monitorze lepiej widać małe litery niż na telefonie.

But Polish word order is flexible, so other versions are possible, depending on emphasis. For example:

• Małe litery lepiej widać na tym monitorze niż na telefonie.
• Lepiej widać małe litery na tym monitorze niż na telefonie.

The original version emphasizes the location first: on this monitor.

So the word order is not completely fixed, but the original is smooth and idiomatic.

It is neutral and natural. It works in everyday speech and in normal written Polish.

Nothing in it is especially slangy or especially formal. It is just a straightforward observation about readability on devices.
