Helloo
Trying to get my tv to display at 120hz from my computer.

In the intel HD control panel i have the option to select 800x600 up to 120hz but if i select anything higher than 85hz the tv says "not support". :eek:

This is odd as the driver detects i can display 120hz but something goes wrong.

Any ideas?

_____
and yes i need 120hz as it provides a more perfect control with the quake engine and i play on a professional level.


thanks for your help

I contacted my tv's manufactur and they stated that it should indeed accept a 120hz signal and display at 120hz. They even suggested that I try another pc if i had one.


It also has a 120hz badge on the front of the tv.


and also 85hz works. so its not capped at 60 for sure

It will take 85hz. So it's definitely not the standard tv capped at 60hz.

Also the hdmi cable the tv specified stated it was 120 hz ready.

IDK i'm just leaning towards a problem with the intel video drivers or windows 7. As i've seen some complaints rolling around about not being able to set more that 85hz.
 


It doesn't matter how high speed the cable is, the TV's HDMI connection has to support HDMI 1.4b to run at 120hz. It is only as strong as its weakest link, and the TV's connection is the weak link.
 


You'll have to search for the HDMI version, but if it is not HDMI 1.4b, which there are none used yet in the industry, it will not support 120hz, except through frame packing, which is a HD3D thing and that requires HDMI 1.4a.

i was in a house fire and my equipment burned. I was also burned with 2/3 degree over 30 percent of my body. Had to have skin grafts.

this tv thing is the only thing i have to work with atm as i'm disabled and back living with my parents ;(

also this tv work really well out of the rgb port. I was pleasantly suprised therese very little noticable ghosting and only 5ms response time. It works better as is than with alot of the monitors i've used in the past. If i coulda got the extra 35 frames it would work.

It is a little 2 big though. :heink:


thanks for you help guys

The worst that will happen to your TV if you try to force 120 Hz is that it will just say the signal is not supported.

In the back of the manual, it should have a table that shows the maximum resolution and refresh rate the TV supports.
