This should be simple, but of course I can't get it to work. I have an Acer laptop with Win 10 and Intel graphics. If I plug my Sony TV into the HDMI port, it all works fine and the driver correctly recognises it as a Sony TV. The problem is that it only displays in a window with big black borders on each side. Whatever I try, I can't get it to fill the screen. I have gone through all the scaling options and different resolutions and everything else I can think of, but nothing changes it. Display on the laptop itself is correct, of course. If I do the same thing on another laptop running Win 7 it works perfectly. How do I get this damn thing to scale correctly on the TV?

On a Samsung you put it in that HDMI which also says DVI. Which Model TV is it and which HDMI port are you in.

Otherwise you may need to set the input type to DVI-PC.

Also there is often a 'Picture Size' that needs to be set to full.

I suspect it'll be your GPU Overscan settings - pop into whichever vendor's drivers you're using and look for that.

I will take a look but I don't want to change any settings on the TV, which is used for different things. I am connecting via an HDMI switch, which links to the HDMI 1 input. The TV is a Sony Bravia KDL-50W670A. This works fine with other laptops. I imagine the problem has to do with Windows 10, which seems to make everything worse.

Sorry, another reply snuck in. This is an Intel display with the stock driver that comes with that. I took a look but it doesn't give away much information. The one thing I don't want to do is screw up what already works, which is the main laptop display. I have been down that rabbit hole before.

I have been here before but went through it all again. I can't find anything that makes any difference, either on the Sony or the laptop. The Intel driver gives lots of options, but most can't be selected or offer only one choice. A lot of options are dumbed down and it is hard to know what they actually apply to. I can't find anything relating to overscan, also not on the Sony. There are a couple of things having to do with the display, but they are unclear and they don't make a difference. I can do all kinds of things that screw up the image in the window, but I can't do anything to make the window any bigger. I will keep looking.

Do you have the actual intel driver software installed or just what windows puts there? Because there should be overscan compensation in the intel software which is on by default because TVs are stupid and follow stupid standards invented by the idiots in the broadcast world.

While you are in there check that its set to full range HDMI and RGB mode unless you are only watching video sourced from the world of broadcast with its illogical limted bit depth.

I have what Windows put there. In the meantime, I tested the laptop on a Panny TV and it works fine. I then tested it on HDMI 2 of the Sony (eliminating the HDMI switch) and I still have the problem. Clearly the Sony is crap or it just doesn't like the Intel driver, which is crap, or both are crap. It doesn't help that Sony uses its own terminology for things. No mention of overscan, just 'full pixel', 'normal' or '-1' (none of which help).

The computer sees the display as a TV and uses the TV modes where it assumes the TV will have overscan, so has to scale it down to be smaller so that its not cut off by the TVs overscan. This is an option in the intel software so go grab their drivers and if it doesnt sort itself out, the option is in there to fix it.

I have the Intel Graphics control panel on the laptop and it recognises the Sony TV but I can't find any options that affect the size of the display. Under scaling it only gives me the option to centre the display. Under advanced options there is nothing that relates to scaling. If I change the resolution, it distorts the image on the laptop but does not affect the TV. It then switches from Sony TV back to built-in display.

i like how because you cant find the setting the tv is automatically crap.

i would say what you want to do is 100% possible which makes neither the TV or the intel drivers crap.

They are both working as they are suppose to as they use different standards which generally are used together, but can be when setup correctly.

Fix Overscan Using Intel Graphics Driver

If you use Intel Graphics Drivers (i.e. if you have an Intel CPU), then you can use the Intel Graphics Control Panel to fix the overscan on your TV.

Go to the Intel HD Graphics Control Panel (either through the taskbar or by right-clicking on your desktop and finding it there). In the Control Panel click “General Settings,” select the TV from the “Display” dropdown, then click “Customize Aspect Ratio” under Scaling.

Finally, use the sliders in the “Preview” image to the right to adjust the picture until it fits on your TV.

easiest way to to do it on the TV though

can also try If you go to device manager and open up your display adapters you should see your Intel graphics chip. Right click on it and disable it. Now enable it again.
