Hi All.

I think this is the right place for this post.

Finally got around to connecting the HDMI cable between my PC and Monitor today, about time I got rid of the VGA.

When reading the below, bear in mind that on VGA, there were 0 problems at 1440*900)

First thing I noticed, the edges of the display were missing (can't see left half, about 50%, of the Start button and the same amount on the other side).

No problem, I thought, wrong resolution. So I go check. The documents for the monitor state that the Native res is 1440*900, and this is what it is set to :(
I change it about a bit and finally find one that works, Finally, I can see the whole screen again. All is good with the world, until I go to read a page in Firefox... The font is barely legible, blurry. I go play with ClearType for about 30 minutes and get something legible but not good by any means. I switch the res back to 1440*900, play with ClearType again and the text is perfect. But, again, I have lost the right and left edges of the display D:

As a last resort I tried the nVidia control panel, and saw that in there was an option for 'Adjust desktop size and position' Perfect! until the options page comes up.. There is a message there saying that my display format does not support this option and I should go to the change resolution page.
Now I am going round in circles, I much prefer having text I can read and not having the edge of the screen to having the edges and not being able to read anything.

Any ideas from you people here?

Short summary: the behaviour described by looks like the monitor (or the HDMI link) is applying overscan/underscan, so a true native 1:1 pixel mapping is being lost and non‑native resolutions look blurry. ’s suggestion to check drivers is on point — both the monitor OSD and the GPU driver control which side does the scaling.

Troubleshooting steps to try (in this order):

  1. Check the monitor OSD for any scaling/overscan settings. Look for names like "PC Mode", "1:1", "Just Scan", "Full Pixel", "Screen Fit" or "Overscan = Off" and enable the 1:1/PC option for the HDMI input.
  2. Confirm the cable is plugged into the discrete GPU output (not motherboard HDMI) and that the monitor identifies as a PC, not a TV.
  3. Update the graphics driver (clean install) so the NVIDIA control panel has full functionality. After updating, open NVIDIA Control Panel -> Display -> Adjust desktop size and position and set "Scaling mode" to "No scaling" (perform scaling on GPU) if available.
  4. If the NV panel won't let you set scaling, try Change resolution -> Customize -> Create custom resolution using the monitor's native 1440x900@60Hz timing so the GPU outputs exact pixels.
  5. If nothing fixes it, try a DVI connection or an HDMI->DVI adapter; DVI often forces true 1:1 pixel mapping for PC monitors.

Notes and cautions: forcing custom timings or overriding EDID can fix the issue but is advanced—use conservative settings (native resolution, 60Hz) and avoid exotic refresh rates. If the monitor manual lists a specific "PC" input mode, use that first.
