the overscan has nothing to do with the driver. It is a "feature" of your Rear Projection TV. Check the user guide of your Rear Projection TV for an option which allows you to switch off the overscan. Very often this option has a name which seems to be not related to overscan. Sometimes the device has no such option, then it's bad luck.
Of course the overscan is caused by my TV. All CRT TVs have overscan, and none of them allow you to turn them off. Only Digital TVs , (LCD and Plasma) have 1 to 1 pixel mapping (no overscan). That is why all the good companies, (ATI and Nvidia), have a correction you can apply to fix overscan. Only Inte has decided to turn off the overscan correction. I have fix the problem by hacking the registry and adding a custom resolution using DTD calculator, no thanks to Intel.
In 184.108.40.2066, there is an "underscan percentage" slider on the Custom Resolutions settings that may meet your needs. In my case, I have been able to address the underscan issue using the "horizontal scaling" and "vertical scaling" options under the general settings for my digital television (a 42" westinghouse).
My Samsung M86 has a "Scan" function, but forgets it whenever I change the source. This means that I have to change it manually each time I use my HTPC. I installed the latest drivers and used the "horizontal scaling" and "vertical scaling" options to fix the overscan.
Does this ruin my 1:1 pixel map or is this an "ok" solution?
This ruin your 1:1 map. After applying H/V sliders, final screen is blurry, interpolated.
Its a crap, i bought new NUC device and I am very angry about this.
My old HTPC with ATI Radeon had overscan correction option, which doesnt affect sharpness, its like 1:1 maping, everythink includind text was sharp!! unlike intel HD4000...grrr
What video interface are you using in that NUC? What is the model of it? What operating system and driver versions are you using?
Is there any adapter or converter being used in between?
I have NUC DC3217IYE, latest BIOS 0042 and latest video driver (downloaded directly from intel support page), Windows 7 64bit Ultimate Edition.
NUC is directly connected with TV (older Samsung) through high speed (class 2) 1.4a HDMI cable.
When I try fix overscan with H/V sliders = final screen is blurry, interpolated!
Please try the troubleshooting available on the following article;
Specifically check under "My HDMI TV overscans where the sides of the desktop screen are not visible. How do I fix this?" and try setting the resolutions listed there.
