Hi there,

I fired up my PC this morning and the display is acting weird—it looks smaller than usual, surrounded by these black bars. (And no, I didn't mess with the CTRL+mouse wheel thing)

It feels like an old issue I used to run into back when I was using Windows XP in safe mode.
Now I'm running Windows 10.

Any idea what's causing this?

Thanks in advance.

Hey, you might want to check if someone messed with your settings and set the aspect ratio to 4:3 instead of 16:9. What kind of monitor are you running?

Dell UltraSharp Monitor

The image is 16:9 inside a 16:9 screen, which means it’s just shrunk down proportionally... leaving a black border about an inch or two wide all around.

I uninstalled Norton last night, so maybe that was causing some interference...

It looks just like this on the website, but I have no idea why my screen randomly shrunk the image and added these borders:

Looks like your resolution got messed up... maybe something went sideways with your graphics card or the drivers? I'd say just head over to your display settings and try to set it back to what it was before...

I played around with the resolution settings for a bit and it looks good now. Thanks. 🙂

Does running at the highest resolution actually hurt the monitor?...

Not at all—if anything, it's better. You really want to stick to the native resolution. For instance, if you've got a screen that's 1920x1080, you definitely want to keep it set right there instead of dropping down to something lower...

Yeah, I set it to the highest one.

I was just asking because I figured maybe those old CRT monitors could get damaged if the resolution or frequency—something like that—was cranked up too high... can't quite remember...

Honestly, I really don't know..

It depends, I guess... I used to have this 22" CRT that could technically handle a 2048*1536 resolution, but man, everything looked tiny and the refresh rate was absolutely abysmal... For me, the sweet spot was probably 1600*1200 at 100 Hz... generally, the higher the refresh rate, the better... though if you're working with an old, beat-up CRT, maybe it makes sense to dial the refresh rate back a little, but I wouldn't go any lower than 60 Hz.

I haven't touched a CRT in about six years; they absolutely trashed my eyes, even if they were indestructible...

Back when I finally picked up my current widescreen LCD, I figured I’d be set for at least a decade or two, and then suddenly they drop these 21:9 displays on us this year!🙂

Yeah, sure, if you care more about the "health" of some old junk than your own eyes.
What do you mean 60Hz, for crying out loud?
I thought the standard was at least 75Hz just to get a flicker-free image, though even that was kind of a flickering mess (just look at a monitor from a sharp side angle and you'll see the massive flickering).
Because of that, those later generations using Trinitron tubes or similar tech could push past 100Hz, obviously depending on what resolution you picked.
That’s why the rule is: you gotta run your CRT at its optimal resolution (linked to the screen size! A 17" and 19" usually had the same resolution, but the 17" made everything look smaller) with the highest possible refresh rate.
There’s no compromise there. Especially nowadays, why would you try to save your monitor when you specifically picked its quality based on what you needed?
Of course, this whole refresh rate thing doesn't apply to LCD monitors since the tech is totally different. You aren't dealing with electron beams hitting phosphor dots that glow and fade; instead, the backlight stays on until the next signal change, and the refresh rate just shows how often that update happens. So for static images, a standard 60Hz LCD is fine, but for fast stuff like gaming, a higher refresh rate helps prevent ghosting and motion blur...

Sure, it might be a bit old-school advice, but you buy gear to serve you. You push it to get the most bang for your buck. Why bother being stingy just to make a CRT last another 10 years?
