I had a Dynex 1080P 19" TV which I used for both TV and as a computer monitor. It worked perfectly, right out of the box. Then, I upgraded to a larger DYNEX and had the problem in which the PC @ 1080P doesn't fill the screen. It turns out this TV was defective. (The computer controls on the TV wouldn't activate when connected to a PC and there was no way to manually activate them.)
I returned it and bought a Sharp LED LCD. My PC didn't fill the screen on it, either. That's when I discovered the overscan setting on my Radeon HD 5450 graphics card. Making that adjustment in the Radeon control panel filled up the screen beautifully.
(It turns out that the Dynex actually was defective, but that didn't have anything to do with filling the screen and the overscan setting on the PC graphics card. It is odd that I never had this issue with my old 1080P Dynex, but did with the new Dynex and the Sharp... Maybe someone can explain why I didn't need to set the overscan on my old 1080P tv, but I did on both of the new one's!)
When I switch between the Blu-Ray and the PC on two separate HDMI inputs, the TV doesn't detect that's it's connected to a PC, so it doesn't switch from video to graphics mode - which is required for it to look good as a computer monitor.
Since the TV deosn't recognize the PC and auto switch to graphics mode, when I switch from Blu-Ray to PC, I have to dig down into the menu and switch the HDMI mode to graphics manually - and then back when I go to the Blu-Ray. -- Major pain if I'm switching back and forth.
So, I have 2 questions:
1. Do any of the HDTV's out there allow you to set the various controls for each input individually and have them remembered? -- So I can have HDMI 1 set to video, and HDMI 2 set to graphics? I've searched and either the feature doesn't exist, I don't know what it's called, or no one bothers to mention it in their specs.
2. Would having a monitor specific driver instead of using the generic Windows 7 monitor driver allow the TV to detect the PC and switch to graphics mode when the HDMI is set to Auto? Right now, Auto just stays in video mode all the time.
I'm using Windows 7 64 bit Home Premium with the Radeon HD 5450 on a Sharp LC-26sv490u tv.
3. Any other tricks to get the HDMI Auto mode on this TV to actually detect the PC and switch to graphics mode?
This TV is only a temporary measure. I plan to get a different model soon, so any sage technical or shopping advice would be greatly appreciated.
