My HP monitor is on the blink so I'm trying to get my Acer AT2001 TV/Monitor to work. On initial bootup all looks fine until windows starts coming up when my screen goes daft. I get the left hand side of the screen on the right hand side and the right hand side on the left with a black line down the middle. It takes great skill trying to click on things with the mouse as clickable items are also inverted. When I go into desktop properties - settings - advanced - monitor it says it's using the default monitor settings which are obviously wrong ! I can't see any drivers on the web for the Acer AT2001 plus I thought XP was supposed to detect new hardware and deal with it ... any ideas please ?

Short diagnostic route to narrow this down (building on ’s report and ’s cable hint):

  • Confirm the physical input in use (VGA, DVI, composite, S‑Video, component). TV inputs and passive adapters need different signals; if an adapter is in use, try a direct VGA/DVI cable first.
  • Boot with basic video so the GPU driver and advanced modes are out of the equation. Restart, press F8, choose “Enable VGA Mode” (or Safe Mode) and observe the picture. If the image is normal in VGA/Safe Mode, the problem is software/driver/resolution; if it’s still wrong, it points at the monitor or the cable.
  • Check the monitor/TV on‑screen menu (OSD). Switch the input to “PC” or “RGB” if available, reset the display to factory defaults, and look for any image flip/mirror or TV processing options and disable them.
  • Update or reinstall the graphics driver if the issue only appears under the normal driver: Device Manager → Display adapters → uninstall/reinstall or install the latest driver from the GPU maker. Also open the GPU control panel (Intel/NVIDIA/AMD) and verify there’s no rotation/mirror set.
  • Swap hardware to isolate the fault: connect the Acer to a different PC, and connect the original HP monitor to the PC that behaves oddly. If the fault follows the Acer, it’s the monitor; if it follows the PC, it’s the GPU/drivers.

Notes and cautions: composite/s‑video inputs from PCs often require an active converter — a passive lead can produce strange images. Inspect cables and connector pins for damage. If the problem persists after trying different cables, inputs, and PCs, the scaler/electronics in the AT2001 may be failing and service or replacement is likely. Prioritize the quick tests above to avoid unnecessary purchases.

are u using vga, dvi, composite, component, hdmi, or svideo? if vga, run in safemode with video, or something like that and see if it works
