Fuzzy text on AOC 22" LCD TV (L22W761) as PC monitor

antk 208 September 2, 2008 at 11:31 PM
Greetings everyone,

I recently purchased the AOC 22" LCD TV (http://www.newegg.com/Product/Pro...6889197004) and wanted to use this as a tv/monitor, which it appeared to be perfectly capable of doing.

No issues on TV quality. BUT when I connect my PC via HDMI and try to set the resolution to 1680 x 1050, there is some flickering in application windows and the text appears a bit fuzzy. When I try other lower resolutions (1440x900, 1280x720) the flickering goes away, but the text is still fuzzy.

Here are my hardware specs:

LCD TV - AOC L22W761 (manual says that it should support 1680 x 1050)
Graphics - integrated ATI Radeon XPress 1250 (maybe this is the problem?)

I've updated my graphics drivers, but it didn't do anything. I tried the ATI Catalyst Control Center to manipulate some of the settings, but couldn't find anything there, either.

Does anyone have any suggestions or thoughts on these issues? I'd really appreciate any input at this point. Thanks everyone.

Yup, i'm 99% sure it is the integrated graphic card. I had the same problem when I gave my dad my 17'' monitor, and with his onboard graphic card it's kinda fuzzy with the desktop text, but with my computer I have a PCI-E 256mb Nvidia Gigabyte., it looks good.

I would say get a decent graphic card, mine was 89 bucks.

Not the video card. My old Nvidia GeForce 4 32MB PCI can support 1600x1200 with no issues or flickering. No issues either with my Radeon Xpress 200m on a 22" LCD either.

I'd download the Drivers for the monitor first and give that a try. It made a HUGE difference even when dealing with my IBM 19" LCD - Also needed them for my Dell 20" WFP display.

Have you tried VGA? I had an older monitor which gave issues like this when using a digital source HDMI/DVI, but worked fine over VGA. Most likely you're running your TV setup through component, and don't see any issues.

I haven't tried downloading drivers for the monitor. The website indicates that the drivers are for LCD monitors. Is it the same if I download for an LCD TV? I'm not too educated when it comes to stuff like this.

Yes, I tried VGA, but I wanted to set up dual monitor, so I had to use the VGA port for the second monitor. Also, the max resolution for VGA on my LCD TV is 1440x900. I wanted to get the full 1680x1050 out of it by going HDMI. I guess HDMI isn't really made for PC signals? No idea.

Does your Video card support HDMI? How are you hooking the AOC to your PC?

I'm hooking the AOC to my PC through HDMI. My motherboard has integrated graphics (GIGABYTE GA-MA69GM-S2H).

Your HDMI ouput should be able to do at LEAST 1080p (1920x1080?) so it's definintely not the Video Card. I'd load the drivers. The specs on their TV's are pretty close to the specs on their Monitors so the panel is probably the same or similar. The differences primarily seem to be related to a built in Tuner or Audio input/output. ... which is really the only difference between a TV And Monitor these days. - It was different with CRT Monitors because a TV only had a resolution of 320x240 where a 14" CRT monitor was running 640x480.

Next step is Monitor drivers.

In case there are a few others with this problem following this thread, I also found this wiki:

http://pixelmapping.wikispaces.co...+explained

It's a year old, but the info's pretty interesting. Maybe my lcd tv doesn't do this 1:1 pixel mapping.
