Display on desktop looks fuzzy when increased to higher resolutions on TV

post #1 of 12
Thread Starter 
Hi guys, so i built a computer for my friend according to his budget he got an MSI GTX 650ti and he currently is connecting it via HDMI to a 40" Samsung LCD TV. I do not know the exact model of the TV right now but i can find out later when i come over again to my friend's house. Basically, the graphics card itself is capable of 1920x1080 resolution.... its at a 1024x768 (i think) recommended resolution... which looks clear and crisp...with text easy to read and colors vibrant as they need to be... but then as soon as i increase my resolution (not in Nvidia Control Panel - in Windows Screen Resolution window) to 1920x1080, it can do it.... but then the display picture quality gets really dull and kind of blurry and hard to read with the text being really difficult.... im not sure how to describe it. I had to leave from my friends house but i have to go back later to fix it.... not sure where i should start on troubleshooting... for the 5 minutes i had before i had to leave i tried to do some things on Nvidia Control Panel but everything i would do at a resolution higher than the 1024x768.... would be unclear... why is it like this? He currently doesnt have internet for the computer as he is trying to order a wifi USB stick right now so we cannot install new drivers.... but is this a driver issue ? or is this a monitor issue? I could always try reinstalling a new driver, (im using the one in the CD to temporarily get it going while he is ordering his wifi USB stick)... but if its not a driver issue then what could it be ?

Has it been possible before that a 40" TV just cant display 1080p? If its only like 720p or something? Im not even sure if the TV he is using is 1080p or 720p, it had a pretty thick bezel around it so it might have looked like an older model? but not too sure....

what can you guys say about this? im really not sure why this is happening, i have a 40" TV too thats 1080p and it seems to do fine when i put the resolution that high, but on his TV it doesnt work...

Will give out reps to good advice. Im completely stumped confused.gif

Even if the TV can support the max resolution, TVs in general are very problematic when you try to get a crisp picture from PC.
Once I literally counted the pixels on my TV and set the absolute correct resolution, and it didn't set it correctly, it was a complete mess, uneven blurriness everywhere..

There are settings in Nvidia control panel which you can use to regulate the width and height of the image so that it fits correctly on the TV. From then on... It very much depends on how this particular TV behaves. You might be able to get perfect image, or you might not.

On the lower recommended resolution, it would show the desktop perfectly fine, perfect size no help needed from NV control panel, but i know what youre talking about with how you can adjust it in NV control panel... but when i up the resolution, its supposed to just get bigger.... but the display actually becomes super unclear... why is it like this ?

Its the TV right? Its not the graphics card i chose him? Thought i got him a good card for his budget...

Check in the windows resolution settings what the TV reports as its native resolution?

If the TV can display 1080p, and it still looks fuzzy it can just be a overscan/underscan problem. I'm not really familiar with Nvidia Control Panel, but there should be a setting for Overscan/Underscan (Panel options?, HDMI?) that can be adjusted, assuming there is a black bezel *on screen. Sound like the same issue when I plug my PC to my TV over HDMI, if the overscan isn't set correctly at 1080p, then everything on screen looks fuzzy and lacks sharpness.

Native resolution said it was the uhhh 1024x768.... I remember trying to do underscan/overscan on NV control panel and that didnt work.... or change anything... maybe i can try it again....

Make sure the av channel is designated PC ( label or whatever they call it i.e HDMI PC )

And have found text is usually affected by the sharp settings smile.gif

ive never gotten TV's to look right when hooked up to a PC unless you do some super low res. 1080p always looks like crap no matter the cost/brand of tv.

Try changing the actual TV settings, usually called "AV Mode" or something and set it to Game or PC mode. I get crazy amounts of lag or horrible picture quality without doing so on my home setup. We have a number of TV's displaying only power point presentations at work, if the TV's are not set to the proper mode (PC) it looks like crap even though it's just a slide show.

Damn..... 1024x768 native on a 40" TV wth.gif I'm assuming its a normal 16:9 aspect ratio, so the TV is not reporting correctly....

Only two things that I can think may be the problem.... Drivers and TV settings. I know some TV's have a setting that must be selected in order for it to correctly display from a PC(seen it called PC Mode, Display Mode). A lot of TV's can just adapt automatically to whaterver is feeding it a signal but I have come across a few that don't.

Otherwise try the drivers and try hooking up a different PC to the TV

I remember it having a PC mode for this TV, and in the back for the PC mode, is a VGA input. I tried putting in a VGA cable and using a VGA - > DVI adapter... but i couldnt get a resolution higher than the 1024x768 native resolution. So PC mode isnt even HDMI. Seems like its an old TV?

The only options are PC mode (VGA), Cable, or HDMI inputs that are in... and the only one showing is the only one plugged in to the computer and that is HDMI 1.

What does aspect ratio mean? Like in terms of this problem? Okay i will try reinstalling drivers (hopefully that fixes the problem) but JUST IN CASE i want to try other things just so i wont look dumb or anything like i dont know how to fix it..... or know whats causing it... But i will try to find some sort of setting on the remote to adjust the display mode made there is some sort of button that changes how wide or something it can be.... so maybe thats messing it up? Im not too sure if there is that setting at all but maybe when i go over next time i can check it out?
