Good follow-ups from and . The suggestions already in the thread are useful; what follows adds concrete checks and fixes that aren’t mentioned yet and often make the picture noticeably cleaner.

First, software and drivers: make sure the ATI TV drivers and the TV application are up to date. Try a different capture/viewer (for example a generic capture tool) to see if the problem is the card or the TV app. In the TV software look for picture filters — deinterlacing mode, comb/noise filters, chroma/luma adjustments and any sharpening. Switching deinterlace/filter modes or turning off aggressive sharpening can reduce visible grain and combing. Also check capture format (YUY2 vs RGB) and CPU usage while viewing; high CPU load or bad codec settings can introduce artifacts.

Hardware and signal path: prefer the tuner’s Y/C (S‑Video) input over composite/RF when possible. Inspect the coax run and all connectors for corrosion or loose F‑type fittings, and avoid multiple cheap splitters in the chain. Use good 75 ohm, low‑loss coax and proper compression F connectors rather than makeshift adapters. Keep the coax away from mains wiring or noisy devices and add a ferrite choke if you see interference. If over‑the‑air signals are weak, a proper inline preamp/distribution amp helps; don’t rely on marginal splitters.

About Monster Cable: brand name matters less than correct specs. For TV tuners get a 75 ohm, low‑loss RG‑6 cable with solid compression F connectors and good shielding. Expensive retail brands don’t always outperform a well‑made run of the right spec cable.

If those steps don’t help, try moving the card to another PCI slot, check Device Manager for resource conflicts, and test with a known clean source (DVD/player or set‑top box via S‑Video) to isolate whether the tuner itself is the limiting factor.

Use better cable. That's a big help sometimes. (Especially if you made a coaxal cable and didn't buy it. They're hard to make!)

Run the input through a VCR first. The VCR amplifies the signal before it gets to the TV, so you get a stronger signal. I can pull in Comcast Sports net only if I go through the VCR. (Comcast in Fort Wayne has really poor cable quality.)

You will probably see some fuzzyness. The reason is NTSC (standard TV) resolution is 388x240, while standard computer resolution is 800x600. Many monitors run at 1024x768, so what probably happens is digital enlargement. Digital enlargement tends to be grainy.

Better cable as in Monster Cable?
