Monitor issues/ GPU. Help!

post #1 of 10
Thread Starter 
I have got a monitor using with that video card ( AMD HD 7870 XT JOKER), and the monitor can support a resolution up to 1920 x 1080, if I apply this resolution I won't be able to read text, gaming graphics gets bad and ugly. Apparently if I use it for my big TV in my living room with is Sony 42 inches, every thing works fine, good graphics, clear text and so on. Can anyone tell me what to do with this my monitor? The monitor is got both TV, CD drive included, and also compatible with PC. here is the monitor http://direct.asda.com/Luxor-LUX-19-822-COB-19ins-HD-Ready-LCD-TV-with-Built-in-DVD-Player---Black/000593759,default,pd.html

can you further elaborate cable type connection from graphics card to your monitor? is it HDMI, DVI or VGA? if your monitor output is VGA and your graphics card is DVI and you are using an adapter e.g. VGA to DVI and vice versa, its quite possible that is the culprit.

got the same problem with my daughter's desktop pc using a 19" monitor with VGA output connected to a GTX 285 DVI terminal using an adapter that causes the monitor to blackout, continuously flickers and remains black. You can try using converter VGA to DVI installed at your monitor terminal, you can also try a new highly rated DVI cable (1920 x 1080), that is if you are using a VGA to DVI adapter.

and lastly, buying a new monitor with both DVI and VGA output terminal solve my problem. I highly recommend monitor with DVI output terminal.

Yes I am using HDMI cable, do you mean it is the quality of my cable that is causing this problem ?

The monitor you linked is 1366 x 768 resolution.

The TV is probably trying to scale down 1080 resolution.

Try going into CCC and looking under "My Digital Flats". Try looking at scaling and make sure it is at 0%. Actually I'm thinking of the wrong word for it. Just mess around with some of the settings.

its highly possible that your HDMI connection is creating that problem, i highly recommend to use HDMI.

I've also have this problem before using HDMI cable connected directly to HDMI terminal of my PC with GTX 560 and resolve it using purely DVI cable from monitor to graphics card without using any adapter, since my monitor has both DVI and HDMI terminal.

Try using purely DVI connection from monitor to graphics card.

how, it has only VGA port and HDMI port. If I chose a resolution as low as 1024x768 (not very sure) I can get 75 Hertz which makes the monitor a bit better. Instead if I chose above that resolution I only get 60 Hertz which is very bad to even read texts. If I am playing games such as fifa 13 the graphics looks like the contrasts , brightness and color is too high. I get the same problem if I play videos from the monitor, but the fact is the monitor is got DVD from built in, I insert a dusk and try to watch a movie, there was nothing wrong with the quality of the movie, there was nothing like hight contrasts and color. Just like if I play video from my hdd if I am using the monitor in in PC mode. I was watching movie if was fine I switched to watch clips and play games with the PC the graphics got very bad.

try using an adapter VGA to DVI either on your monitor terminal or GPU terminal. Below are link to sample photos of these adapters. since your monitor only got VGA and HDMI port.

I will buy that cable, but for now I am thinking of buying a new monitor. I think the fault is from the monitor , this is because my 42 inches had no issues with my PC when I connected it to it last time, but I also had no issues when I conneted this monitor r http://direct.asda.com/Luxor-LUX-19-822-COB-19ins-HD-Ready-LCD-TV-with-Built-in-DVD-Player---Black/000593759,default,pd.html to a lads pc.
