Help with new LCD Tv

[Postbiological]

Hi, I just bought a Samsung 26" LCD TV and hooked it up via HDMI to my Radeon HD5770.

I am getting a picture, but if I am using monitor scaling (with the GPU scaling tab unchecked), the picture looks like crap... hard to read text, fuzzy and kind of pixelated (at native resolution of 1920 x 1080)...

However, if I select GPU scaling, the picture looks good, text looks fine etc, except that about 30% of the screen is cut off... in Windows if I move my mouse to the right it scrolls over to the rest of the screen...

I don't know why this is happening when I have it set at 1920 x 1080, which is the monitor's native resolution....

Any ideas on what I can do? I have already tried upgrading drivers and playing around with the various options

Thanks!

Did you adjusting the picture size on the TV - ie. zoom, just scan, etc?

Some Tv do not like the resolution timings that video cards put out. I have a hitachi that looks bad if I send it the resolution 1280x720, it is 720p tv. The reason is that the actual resolution of the screen is 1366x720 . Hitachi does some post processing to increase the resolution slightly but still list the set as 720p. If I look at the tv info for 1280x720 it shows 1280x720 . If I go into ATI control panel , under HDTV support and click ADD 720P60 format then use that resolution the tv looks great and the info on the tv shows 720P. Try adding 1080p in the HDTV menu on the ati control panel and see if it looks better. HDMI is funny how it determines what resolution. If you set the resolution and send it to the tv, it will try to display that resolution, but if you set a format like 720p/1080p the tv will work off the internal presets.

That is the main reason I tell people not to buy a LCD tv and plan to use it as a pc monitor.

@ Icepickfreak, for some reason those options are not selectable in the menu

@ Modelworks, thanks for the suggestion... my concern is that when I try to add a resolution, it says it could damage the monitor

It won't harm the monitor. It will either show a picture or it will not show a picture. That warning is a leftover from CRT monitors.

Not in the menu, it should be on your remote. There should be a button labeled "P.Size" that will cycle through the different modes.
