Hi,
I have an Intel Core i5 with built-in HD GMA Graphics and I run into a problem that is just really frustrating to solve.
I'm not a gamer and I mostly want to watch videos and DVDs out of my PC and I want to connect the computer to my Samsung 50" HDTV.
However, when I use the HDMI-to-HDMI cable, the picture that is shown on the HDTV is too big and it spills out of the border of the TV and I cannot see the edges of the monitor, including the BIOS setting page from the motherboard. Intel supports GMA drivers and graphics utility that can set the resolution to native 1280x720 and Windows 7 looks good and normal on TV. But it's just that I cannot play around with the motherboard BIOS to set up certain things that I wanted to do.
So I have another HDMI-to-DVI cable that came with an old DVD player and when I use this cable from HDMI output of my PC to the DVI input of the HDTV, the BIOS image and text comes out perfectly just like a PC. But when I go to Windows, the resolution for 1280x720 is cut off with black bars around the image, it's too small and it's not looking like a real full-screen HDTV. Using the Intel graphics utility, I can change the resolution to 1920x1080 and manually adjust the horizontal and vertical scaling to fit the length and width of the TV. But in doing so, the text quality is awful and too small. My HDTV supports both these resolutions.
So in short, HDMI-to-HDMI produces good pictures on Windows but scaling problem with native BIOS settings, HDMI-to-DVI produces normal image on BIOS but reduced resolution on Windows.
Questions:
1. From what I understand, HDMI and DVI have identical video data so why on earth the DVI and HDMI resolution can be so different on the same TV? What's going on?
2. Is this a hardware problem that is inherent to Intel GMA? I don't want to spend any money to buy a graphics card if I can.
3. Any suggestion how to fix this?
Thanks in advance.
