Ok, just found this forum and hopefully it will be a life saver. I cannot get the screen to the right resolution. The video card I have is the HIS Radeon 9550. I purchsed it to get the DVi output until I build a new rig. I can only get it to 1024x768. When I did get the resolution to 1360x768 I head those green dots that appear randomly. So close yet so far away I am also using DNA drivers. Any help would be wonderful.

I have an Element Electronics 32" LCD Specs as follows:

Product Specs:
• Resolution: 1366 x 768
• Brightness: 500 cd/m2
• Contrast ratio: 800:1
• Response time: 16 ms
• Viewing angle: 170 x 170

Inputs/Outputs:
• HDMI input
• VGA (D-sub) input
• 2 Component video inputs (YPbPr/YCbCr)
• S-video input
• Composite video input
• 2 TV/CATV coaxial RF inputs
• 7 audio inputs
• Audio output
• Coaxial digital audio output
• Headphone jack

Product Features:
• 1080i/720p/480i/480p digital compatability
• Progressive scan
• Dual Tuner Picture-in-Picture (1 ATSC, 1 NTSC)
• 3:2 & 2:2 pull-down with motion compensation
• Built-in stereo speaker system with SAP sound (10 watts x 2)
• Simulated surround sound and digital noise reduction
• Bass, balance, EQ and treble control
• Trilingual on-screen display (English, Spanish, French)
• Input and channel label
• Sleep timer
• Closed captioning
• Includes full-function universal remote control and detachable TV stand
 
the green dots are called artifacting or in other words your video card is overheating.
 
Thanks. Is there a card you can suggest. So I can get that resolution "1366x768". Looking for an AGP card for a quick solution until I go PCi express.
 
With a DVI input and a max res of 1366x768, the BEST resolution for your TV is 1280x768. I have a system running on a dell 26" tv/monitor with the same max screen resolution and 1280x768 should be optimal. You can force 1680x1050 with an adapter if you want. And your TV should be set at 720p.

You can also attempt to customize your resolution settings if your cards control panel has the option.




 
theres a guide for this in the HTPC section.

heres the link to the FAQ for "Stuff for HTPC": http://www.hardforum.com/showthread.php?t=759011

go to the "Powerstrip and You" section and check out the link for "Creating Custom Resolutions"

the green dots you are seeing could either be:
1) video card overheating
2) dead pixels (if the green dots appear in random places then they are not dead pixels)
3) forcing a "weird" resolution on the LCD

you should check the ventilation on the video card and if it seems cool enough, as its the most likely cause of the green dots.

EDIT: you said you're using the DVI output on the radeon 9550 to connect to the TV but how exactly are you doing this? the specs you posted for the LCD does not list DVI as a input? i would recommend you use the vga input on your LCD for best results if you are not already doing so.
 
Sounds like you may be trying to display a rez either the card or the LCD doesn't like

I think the OP already knows this info, but I'll post it for ppl who may not(taken from here) :

So I have one of the 1366x768 flat panels how do I get the best results with it?
Using 1366x768 causes one issue for a PC which is that 1366 pixels is not divisible by 8 and due to legacy issues PC graphics cards cannot typically produce a resolution that isn't divisible by eight. Thus 1360x768 or 1368x768 are the closest resolutions. The newest drivers from NVIDIA and ATI are fairly good at working with the 1366x768 sets and can set 1368 and trim 2 pixels off to match it.

NOTE: Custom resolutions such as 1360x768 are only available with VGA or DVI/HDMI. Component video ouput is locked into the standard DTV resolutions (480i, 480p, 576i, 576p, 720p, 1080i).

I'd give the official drivers a shot before you blow more money.
 
I have a 32" 1366x768 Sharp Aquos and I got it running at the native resolution using powerstrip on a geforce 7600gs...

I used the powerstrip tutorial linked above...
 
I had hooked my system to my roommate's LCD TV with that resolution. However, somehow, my framerates dropped a lot in all my games. FEAR went from 70-200 to 30-50 just by forcing 1360x768 (the TV's manual said that computers should be set to 1360, not 1366)...dunno what you've experienced.
 
I am using a DVI to HDMI cable. I got it set at 1280x720 right now. I cannot even get it to show at 1360x768 at all I could before but now nothing. The text is not as crisp as it is when the resolution was at 1360x768, when I could get the monitor to show at the resolution, but I had those radom artifacts. I gues I'll have to deal with it for now. Thanks for all your help. Still open to suggestions.
 
Be careful suggesting people use Powerstrip. The OP is using a Radeon 9550. Even using Powerstrip it cannot do 1366x768 due to inherent ATI hardware limitations (see Entech's own advice here: Horizontal timing and pixel-perfect resolutions).

Also, don't forget that many manufacturers don't want you to connect the TV to a PC and have done weird things to the digital inputs (esp. HDMI, but even DVI can be stuffed up). E.g. see:

whats 6 more pixels? lol

Quite a lot actually ... they "break" the original VGA controller design (see the Entech link above).
 
Well tried VGA and still no luck. Still cannot display it at 1360x768.

I also tried it on another PC I have set up running as a server with a Radeon 7000 VE. and cannot get it to display anything but 800x600 at first. I got it to use 1280x720 but it did not feel the whole screen.

Is a Nvidia card a better solution or should I be looking to upgrade to PCI express or a HDCP card?

I got an Olevia 32inch LCD TV. MAx resolution is 1366X768. (yes i use the DVI output)

What I found to work was using powerstrip and putting the resolution at 1280X768, because thats the max PC resolution it said it can go to (on the specs, on there website),

Might wanna give that a try. Everything works great so far except CS:S I lag so hard in that game now and CANNOT figure out why.

Hopefully this helps man
