DVI -> HDMI & Goodmans GTVL27W23HD HDTV help (1 Viewer)

[cheetah05]

Hi there,

I want to use the HDMI socket on this tv set: Goodmans GTVL27W23HD for my HTPC.

My HTPC has an ATI Xpress200 graphics card, but picks up as an X1150 in Catalyst, probably due to the fact i have set the memory to as high as it can go in the bios.

Now i have a DVI to HDMI cable (1 meter) manufactured by HD Cable. The specification of the cable can be found here: Clicky!.

I have plugged the cable into the DVI output on my computer and the HDMI input on my TV but i can't seem to get it to display correctly.

Basically when i got to display settings (Windows Vista) and i select the resolution 1360*768 it shows on the screen and the screen refreshes but thinks the input is 1080p (1920*1080 - it displays this on screen) and it does a weird resize/scale/pan and it displays all squashed and in the middle.

When I open up CCC it picks up the tv and the model but things it has a maximum resolution of (1920*1080) when infact its 1360*768.

Also the screen has a flicker on it.

Does anyone know how to solve my problems.

When i use a VGA cable from the VGA output, it displays properly, but I want to setup HDMI.

Thanks.

I have experienced similar issues with my setup and I found out that my (and many others) TV sets are clearly differentiate between:

VGA input
If the VGA input is used, most TV sets accept the native display resolution only. This resolution is unique to each TV set but today most likely 1360 (or 1366 or 1368) * 768 (or 760). The refresh rate has to be set to 50 Hz or 60 Hz (please have a look into the users manual of your TV).

DVI / HDMI
If the DVI or HDMI input is used, most TV sets accept only 720p or 1080i resolutions. That means 1280 x 720 or 1920 x 1080. Also, the refresh rate has to be set appropriately to either 50 Hz or 60 Hz. Again, please see the users manual of your TV set.

In addition, some TV sets are doing an overscan, if you are using the DVI/HDMI input. My Samsung LCD TV e.g. is doing a 20% overscan, which unfortunately cannot be influenced. This results in the cropping of the Windows task bar...

If the VGA input is used, most TV sets are not performing any overscan. For this reason, many people are still using the VGA input instead of the DVI / HDMI input.

Best regards,
