Ok, so I connected my new TV to my PC via a HDMI. My PC-screen works (still) and the TV otherwise too, but a little bit from the top and bottom is hidden in the TV. How to get identical display happening for the TV too?

Click on the Windows 10 notification symbol in the low right on the task bar -> Choose Project in the lower panel -> choose Duplicate, or Mirror or something. Otherwise you will just extend the display, and, if the TV screen has a different resolution than your PC monitor, the picture will be cut.

I have done duplicating already, everything is otherwise ok, but yeah, the TV has it's very top and bottom cut out. Is there anything I can do for that problem then?

Try the "Only secondary display" option then. Duplicate should work though. I don't know why it doesn't work in your case.

check the TV settings - most have an 'overscan' option per port (may be called other things) - often defaults on to get around artifacts in the top few scanlines of tv broadcasts by slightly upscaling the image, turning it off will give a 1:1 pixel relationship

make sure the tv isn't zooming the signal. on a roku tv, it calls a clean signal "direct"

I only picked up the TV for my PC.
And now the dimensions are ok. 1762 x 992
But the quality of the screen itself is like given on the attachment pic. i.e. shit.

This is a Samsung 32*

The joke is on me if the quality for you is ok though.

Televisions are not usually very good as monitors, but anything over 1080p should look okay in theory. Even a Walmart Roku 4K television looks pretty fantastic up close, actually. I think we are used to IPS screens from our laptops and phones, and so to compensate, you have to go higher resolution than normal to get the same quality out of a television.

If the quality is bad, then the TV is probably not running at its native resolution.

And why do you run 1762 x 992? That's surely not its native resolution.

Try to use only the secondary display (the TV). That should make it run at its native resolution.

I think that is the television's native resolution and part of the problem. Televisions are not made to be looked at from less than a meter away, with exception of many 4k ones. 720p may look good on a phone screen, but on a television like five times the size, you need a higher resolution if you're going to be working closely and expect that same pixel spread. This isn't accounting for LED verses IPS screens and a variety of other factors, as well. Turning up the sharpness can help, but only so much.

that the viewable area is that really odd number ( which is exactly 82% of fullHD/1920x1080) indicates the tv has the overscan/zoom function enabled. As I and others have already said, go hunt thru the TV menus for the setting and disable it - chasing the issue from the PC side is not going to give you a fix

chk071 · Post by **chk071** » Sun Mar 21, 2021 7:10 pm

Yes. 1762x992 is definitely not the native resolution of the TV, and also the reason why the picture isn't sharp.

Thanks for helping me, but I've decided to use it as a TV only and buy a proper 4k screen - I can get a proper one for 300€.

My main problem with some computer displays and almost ALL LCD TVs, is
that they use PWM.
Why PWM is bad

https://www.notebookcheck.net/Why-Pulse ... 240.0.html
At least avoid the low frequency PWM models...

Look at this chart sorted by Flicker-Free score, click in the model name for the review.

Best display review sites: (Check for PWM, flicker free probably means no PWM)

if you're in Windows and have an Nvidia card, you can adjust overscan in the nvidia control panel (adjust desktop size and position panel). also make sure to go to the advanced tab under "adjust video color and settings" and set dynamic range to "full".

Need help to get the new TV/Monitor resolution right
